From Coffee Shop Counter to Wholesome Home Creation

Before diving deep into the world of nutrition and fitness, I spent several fulfilling years as a barista. It was, without a doubt, one of my most cherished jobs. I thrived on the daily interactions, the vibrant social atmosphere, and the joy of connecting with people over a cup of coffee. But what truly ignited my passion was the endless creativity of crafting new drink combinations. I vividly recall one particular drink that soared in popularity: a luscious white chocolate mocha infused with creamy peanut butter and a hint of toasted marshmallow syrup. It was a symphony of sweet, nutty, and creamy notes that customers couldn’t get enough of, and it left a lasting impression on my taste buds.

Reimagining the Marshmallow Latte: A Nourishing Upgrade

That magical coffee shop creation inspired me to embark on a mission: to recreate its essence at home, but with a focus on wholesome, natural ingredients – free from artificial flavors, preservatives, and refined sugars. The result? This sensational Peanut Butter Latte with homemade marshmallow fluff, and trust me, we are still completely obsessed! It’s built on a foundation of real, velvety peanut butter, ensuring the richest, most authentic flavor. The star, however, is our unique homemade marshmallow fluff, naturally sweetened with pure maple syrup and ingeniously crafted to support gut health. This latte isn’t just a drink; it’s a nostalgic journey back to classic “fluffernutter” vibes, elevated with a nourishing, guilt-free twist. It’s a testament to how truly decadent treats can also be incredibly good for you.

Crafting the Perfect Peanut Butter Latte: Key Ingredients

To achieve the ultimate rich, creamy, and wholesome Peanut Butter Latte, selecting the right ingredients is key. Here’s what you’ll need and why each component plays a vital role:

Peanut Butter: Opt for a high-quality, natural, creamy peanut butter with minimal added ingredients (just peanuts and salt is ideal). The smoother the texture, the better it will blend into your latte, creating that luscious, velvety mouthfeel. Real peanut butter not only provides incredible flavor but also healthy fats that contribute to satiety.
Milk & Cream of Choice: The foundation of any great latte is creamy milk. For a truly indulgent experience, I highly recommend using a rich and creamy option. My personal preference for a dairy-free version is cashew milk combined with dairy-free NutPods creamer, which offers exceptional richness without the dairy. If you’re not dairy-free or vegan, whole milk and whole milk creamer will also yield fantastic results, providing a classic, full-bodied latte experience.
Homemade Marshmallow Fluff: This is where the magic happens! Our special homemade recipe (detailed in the recipe card below) is simple to make and transforms this latte. You’ll need pure maple syrup for natural sweetness, grass-fed gelatin (or collagen peptides) for that essential gut-healthy boost and fluffy texture, and a touch of vanilla extract to round out the flavors. Making it from scratch ensures you avoid artificial additives found in store-bought versions.
Espresso: The robust heart of your latte. Two shots of freshly brewed espresso provide the perfect caffeine kick and deep coffee flavor that stands up beautifully to the peanut butter. Don’t have an espresso machine? No problem! Check the tips below for excellent alternatives like store-bought canned espresso or strong brewed coffee.
Vanilla Extract: A dash of pure vanilla extract is crucial for enhancing the overall aroma and taste profile of the latte. It adds a subtle warmth and complexity, complementing both the peanut butter and the coffee without the need for additional sugary syrups.
Sea Salt: Just a tiny pinch of sea salt is a game-changer! It beautifully balances the sweetness, amplifies the nutty flavor of the peanut butter, and creates that irresistible “candy bar” effect that makes this latte so uniquely satisfying.
Sweetener (Optional & Customizable): While the marshmallow fluff and maple syrup add natural sweetness, you can adjust to your preference. I often use a few drops of organic monk fruit sweetener for a zero-calorie option. Other great choices include melting a little granulated sugar into your hot espresso, shaking a scoop of flavored protein powder (my favorite is Macro Mike – use code “amb-dani” for a discount!) into your milk for added flavor and protein, or simply adding a dash more maple syrup or honey.

Simple Steps to Your Best Peanut Butter Latte

Creating this gourmet-style latte at home is surprisingly straightforward. Follow these steps for a perfectly blended and delightfully topped beverage:

Step 1: Prepare the Gut-Healthy Marshmallow Fluff. In a small saucepan, sprinkle the gelatin evenly over 1/4 cup of water and let it sit for about 5 minutes to “bloom” and thicken. Meanwhile, gently warm 1/2 cup of maple syrup in a separate pot until it reaches a soft simmer, around 240°F if you’re using a candy thermometer. Once bloomed, carefully stream the warm maple syrup into the gelatin mixture while continuously whisking on high speed (a hand mixer or stand mixer works best). Continue whisking for 5–8 minutes until the mixture transforms into a light, airy, and fluffy marshmallow consistency. This step is crucial for that signature texture!
Step 2: Blend the Latte Base. In a high-speed blender, combine your freshly brewed espresso shots, chosen milk, creamy peanut butter, your preferred sweetener (if using), vanilla extract, and a pinch of sea salt. Blend thoroughly until the mixture is completely smooth, creamy, and develops a beautiful frothy texture. This ensures all ingredients are perfectly emulsified, eliminating any clumps of peanut butter. Pour this luscious latte base into your favorite mug or a tall glass filled with ice for an iced version.
Step 3: Crown Your Creation. Finish your masterpiece with a generous dollop and swirl of the homemade marshmallow fluff. For an extra touch of café elegance, you can lightly toast the fluff with a kitchen torch – this adds a subtle smoky flavor and a beautiful golden-brown finish. Alternatively, if you prefer a cold foam, you can prepare our marshmallow cold foam (recipe included in the recipe card) and spoon it over the top for a decadent cloud-like layer. Stir gently and savor every harmonious sip!

Expert Tips for Your Perfect Peanut Butter Latte

Elevate your homemade latte game with these handy tips and tricks:

Espresso Machine Alternatives: If you don’t own an espresso machine, fear not! You have several excellent options. You can purchase store-bought canned espresso – simply warm it up gently, just enough to easily melt and incorporate the peanut butter, then proceed with the recipe. Alternatively, a strong shot of coffee brewed in a Moka pot, an AeroPress, or even a robust pour-over can serve as a great substitute for traditional espresso.
Boost with Protein: Transform your latte into a post-workout recovery drink or a more substantial breakfast by adding a scoop of your favorite vanilla protein powder. Just add it directly to the blender along with the other latte ingredients in Step 2 for a smooth, creamy, and protein-packed beverage.
Nut Butter Variations: Don’t limit yourself to just peanut butter! Experiment with other creamy nut butters like almond butter or cashew butter for a delightful nutty twist. You can also explore flavored nut butters for an even more unique taste experience.
Decadent Toppings: Elevate your latte with additional toppings. A sprinkle of cacao nibs adds a satisfying crunch and bitter chocolate notes, while a dusting of cacao powder offers a rich, velvety finish. A drizzle of sugar-free chocolate syrup can also be a wonderful addition.
Make it Iced or Hot: This recipe is incredibly versatile. For a refreshing treat, pour the blended latte over ice. For a cozy, comforting drink, warm your milk and blend with hot espresso before adding the fluff.
Storage for Marshmallow Fluff: If you make extra marshmallow fluff (and you probably will!), store it in an airtight container in a cool, dry place for up to two weeks. If it thickens too much, a quick 10-second pop in the microwave will bring it back to its fluffy, spreadable consistency.
Troubleshooting Peanut Butter Clumps: If you find your peanut butter isn’t blending smoothly, ensure your espresso (or coffee substitute) is hot enough to help it melt. Using a blender rather than just stirring is key for a truly homogenous and creamy texture.

Choosing Your At-Home Espresso Machine: My Top Picks

Over the years, I’ve had the pleasure of owning three different at-home espresso machines, spanning various price points. While I’ve loved each one for its unique qualities, my journey eventually led me to invest in a manual espresso machine that closely mimics the professional-grade equipment I used as a barista. Was it an expensive decision? Yes, indeed, and I sometimes try not to dwell on the cost! However, when I consider the significant amount of money my family and I used to spend on coffees out, this investment has truly paid for itself over time. The quality of the espresso it produces is absolutely top-notch – every bit as rich and flavorful as what you’d find in a high-end coffee shop.

For those looking to elevate their home coffee experience, here are a few of my favorite recommendations, catering to different budgets and brewing aspirations:

Rocket Espresso Machine: This is my current pride and joy! Rocket Espresso machines are renowned for their impeccable Italian craftsmanship, the use of premium materials, and their ability to deliver barista-level performance. They are specifically designed for serious home espresso lovers who crave an authentic café-quality experience in the comfort of their own kitchen. If you’re passionate about coffee and ready to invest, this is a phenomenal choice.
The Breville Barista Express is a perennial favorite and one of the most popular entry-level espresso machines for aspiring home baristas. It stands out for offering exceptional value, consistently solid performance, and an intelligent all-in-one design that includes a grinder. This makes it perfect for beginners who want to step up from pod coffee, or anyone looking for a comprehensive machine without the complexity of separate components.
Breville Barista Touch: The Breville Barista Touch is another incredibly popular home espresso machine, and for good reason. It beautifully balances ease of use with advanced customization options, allowing you to craft café-quality drinks with intuitive touch-screen controls. Its sleek, semi-automatic design makes it a fantastic choice for those who want both convenience and control over their brew.
Gaggia Classic E24 (RI9380/46) espresso machine: This machine is one of the most compelling espresso options available for under $500. It boasts authentic hand-built Italian craftsmanship, a robust solid brass boiler, and a highly capable steam wand. It’s a machine that rewards users who are willing to learn proper technique and are open to minor upgrades over time to truly unlock its potential. One of my best friends owns this machine and absolutely adores it, noting its charming aesthetic and space-saving design.
De’Longhi Stilosa is a fantastic choice for those starting their espresso journey, especially if working with a budget under $200. It’s incredibly popular for its approachable design, compact size (ideal for limited counter space), and ease of use, making it a great entry point into the world of home espresso.

Total Time 5 minutes

Course Drinks

Cuisine American

Ingredients

Marshmallow fluff

1 tbsp grass-fed gelatin
1/2 cup water, divided
1/2 cup maple syrup
1 tsp vanilla extract

Assembling the latte

2 espresso shots
1 tbsp creamy peanut butter
1 cup creamy milk of choice
1/4 tsp vanilla extract
1 tbsp maple syrup, honey, or sweetener of choice (optional) *I used a few liquid monk fruit drops
pinch sea salt

Foam (can be made hot or as cold foam)

1/4 cup creamer (e.g., NutPods creamer for dairy-free)
2 tbsp marshmallow fluff
1/4 tsp vanilla extract

Instructions

Marshmallow fluff

In the bowl of a stand mixer (or a large bowl if using a hand mixer), add 1/4 cup of water. Evenly sprinkle 1 tablespoon of grass-fed gelatin over the water. Let this mixture sit undisturbed for 5 minutes to allow the gelatin to bloom and thicken.
In a small saucepan, combine the remaining 1/4 cup of water with 1/2 cup of maple syrup. Place the pot over medium-high heat and bring the mixture to a gentle simmer, heating until it reaches 240°F (if you have a candy thermometer, use it for accuracy).
Attach the whisk attachment to your stand mixer (or prepare your hand mixer). Begin mixing the bloomed gelatin on a slow speed. Slowly and carefully pour the warm maple syrup mixture into the gelatin as you gradually increase the mixer speed to high. Whip the mixture continuously for 3-5 minutes. You’ll notice it slowly thickening and becoming light and fluffy, much like traditional marshmallow fluff. Add 1 teaspoon of vanilla extract during the last minute of whipping.
Once fluffy, spoon the homemade marshmallow fluff into a large glass container. Store it in a cool, dry place for up to two weeks. If you find it has become too thick to easily use, simply microwave it for 10 seconds to soften it before adding to your coffee.

Iced peanut butter latte

For an extra layer of flavor and visual appeal, generously spread some creamy peanut butter and a swirl of marshmallow fluff around the inside of your serving glass.
In a small bowl, combine 1 tbsp peanut butter with 1/4 tsp vanilla and a pinch of sea salt. Pour the hot espresso shots over this mixture to help melt the peanut butter. To ensure a super smooth and creamy latte base, highly recommend transferring this mixture to a blender along with your preferred sweetener (if using) and 1 cup of creamy milk. Blend until perfectly combined and frothy. Pour this blend into your prepared glass filled with ice.
In a separate large glass, add 1/4 cup of cold creamer, 2 tbsp of marshmallow fluff, and 1/4 tsp vanilla. Use a hand frother to froth the mixture vigorously until it becomes thick, airy, and fluffy, creating a delightful cold foam. Gently spoon this frothy marshmallow cold foam over the top of your iced latte. Stir briefly to combine flavors, then enjoy immediately!
Note: The marshmallow fluff may firm up slightly and form small, delicious chunks when it comes into contact with ice, which is completely normal. If you prefer a consistently smooth texture, you might consider enjoying this latte hot or omitting the marshmallow fluff from the cold foam.

Hot peanut butter latte

Begin by swirling some peanut butter and marshmallow fluff around the inside of your favorite coffee mug; this adds both fun and an extra burst of flavor. Gently warm 1 cup of your chosen creamy milk in the coffee cup (or separately on the stove/microwave). In a small bowl, combine 1 tbsp peanut butter with 1/4 tsp vanilla and a pinch of sea salt. Pour your hot espresso shots over the peanut butter mixture and stir vigorously until the peanut butter is completely melted and smoothly incorporated into the espresso. You can add your preferred sweetener at this stage if desired.
For an exceptionally smooth latte with no clumps, pour the warm milk and the espresso-peanut butter mixture into a blender and blend briefly until fully combined and frothy. Then, pour the hot, blended latte into your prepared mug.
To create the luscious foam topping, warm 1/4 cup creamer (e.g., NutPods) in the microwave until hot. Transfer the warm creamer to a large glass and add 2 tbsp of homemade marshmallow fluff. Use a hand frother to vigorously froth the mixture until it becomes super thick, creamy, and airy. Spoon this decadent foam over the top of your hot latte, stir gently, and savor the warm, nutty, and sweet indulgence!

Notes

Don’t let any leftover homemade marshmallow fluff go to waste! It’s incredibly versatile. Use it as a delightful dip for apple slices, spread it on graham crackers or cookies for a healthier twist on s’mores, or even dollop it onto hot chocolate or oatmeal for an extra treat.

*If you don’t have a stand mixer, you can absolutely use a hand mixer to create the marshmallow fluff. It might require a little more patience and arm work, but the results will be just as wonderfully fluffy!

If you don’t have an espresso machine to brew fresh, hot shots, you can easily use store-bought canned espresso. Simply warm it up enough to melt the peanut butter into it smoothly, then use it as directed in the recipe. Strong brewed coffee or a Moka pot can also be great substitutes!
