What is Aquafaba? The Vegan Secret Weapon

Aquafaba, simply put, is chickpea water – the viscous liquid you typically drain and discard from a can of chickpeas. However, this humble liquid is a culinary marvel, serving as an exceptional vegan alternative to egg whites. When whipped, aquafaba transforms into stiff, glossy peaks, mimicking the texture and versatility of meringue. It’s incredibly stable and remarkably easy to work with, making it the perfect foundation for our light-as-air mousse. Instead of letting this valuable ingredient go to waste, we harness its unique properties to create an egg-free dessert that rivals its traditional counterparts.

Aquafaba truly is the answer for countless egg-free and vegan baking endeavors. Its ability to emulsify, bind, and aerate makes it indispensable in a vegan kitchen. For those eager to explore its full potential, this comprehensive article from The Kitchn dives into all things aquafaba and provides various ways to use it.

Wholesome Ingredients for a Guilt-Free Treat

This peanut butter mousse without eggs is crafted using just a handful of thoughtfully selected, nourishing ingredients, ensuring both deliciousness and health benefits:

• Aquafaba: The star of our mousse, providing the essential lift and airy texture. It’s simply the liquid drained from a can of salt-free chickpeas.
• Peanut Butter: Opt for a creamy, runny natural peanut butter without added sugars or oils. This ensures a smooth consistency and rich flavor. You can also experiment with other nut butters like almond butter or cashew butter. For a nut-free option, sunflower butter works beautifully, offering a unique flavor profile.
• Sweetener: I recommend monk fruit powdered sugar for its minimal impact on the aquafaba’s structure, preventing deflation. However, you can use other granulated sweeteners such as coconut sugar, caster sugar, or even powdered erythritol for a sugar-free alternative. Adjust to your sweetness preference.
• Coconut Cream (or Thick Yogurt): This provides richness and helps stabilize the mousse. You’ll need the thick cream that separates and rises to the top of a can of full-fat coconut milk or a dedicated can of coconut cream. Ensure it’s at room temperature for smooth incorporation. As an alternative, a thick, full-fat Greek yogurt or coconut yogurt (dairy or non-dairy, depending on your preference) can be used, but its consistency must be as dense and creamy as coconut cream.
• Vanilla Extract and Sea Salt: These are optional but highly recommended flavor enhancers. Vanilla adds a warm, aromatic depth, while a good pinch of sea salt balances the sweetness and brings out the nutty notes of the peanut butter.
• Cream of Tartar and/or Lemon Juice: These are crucial for stabilizing the aquafaba and significantly speeding up the whipping process. Cream of tartar acts as an acid to firm up the foam, while lemon juice provides an additional boost. While you can use just lemon juice, combining both offers the best and most reliable results for perfectly stiff peaks. You can find cream of tartar in the baking aisle of any grocery store.

How To Make Aquafaba Peanut Butter Mousse Without Eggs: Step-by-Step

Creating this light and airy vegan peanut butter mousse is a straightforward process, whether you’re using a stand mixer or a hand mixer. The key is careful technique and a little patience.

Prepare the Aquafaba:

1. Ensure a Spotless Bowl: Begin by grabbing the metal bowl of your stand mixer or a large, impeccably clean glass bowl. This step is critical: ensure there is absolutely no trace of oil or water in the bowl, as even a tiny drop can prevent the aquafaba from whipping properly.
2. Drain and Add Stabilizers: Using a large strainer, carefully drain the liquid from a can of unsalted chickpeas directly into your clean bowl. Add the cream of tartar and lemon juice (or just lemon juice if you prefer, though both are highly recommended for optimal stability and speed).
3. Whip to Stiff Peaks:
   • Stand Mixer Method: Attach the whisk attachment to your stand mixer. Let it whip the aquafaba on high speed for several minutes. Unlike egg whites, you cannot over-whip aquafaba, so the longer it whips, the stiffer and more stable your peaks will be. Continue until super stiff, glossy peaks form that hold their shape firmly.
   • Hand Mixer Method: If using an electric hand mixer, complete the same steps. Whisk at the highest speed until stiff peaks form. This can take a bit longer, often around 10 minutes or more. You’ll know it’s ready when you can tip the bowl upside down without the aquafaba foam shifting.

Prepare the Peanut Butter Mixture:

4. Combine Wet Ingredients: In a separate large bowl, combine the creamy peanut butter, sweetener (maple syrup or monk fruit), sea salt, vanilla extract, and room-temperature coconut cream (or thick yogurt). Whisk these ingredients vigorously until they are well combined and smooth.
5. Troubleshooting Seizing: Occasionally, depending on the brands of products used, the peanut butter mixture might seize up and become very thick. Don’t worry if this happens! Simply continue whisking vigorously. If it remains too thick, add a tiny splash of water (about ½ to 1 teaspoon) and whisk vigorously again until smooth.

Fold and Chill:

6. Gentle Folding is Key: Immediately begin adding small amounts of the whipped aquafaba to your peanut butter mixture, folding it in very carefully. It’s normal for the mousse to deflate a bit during this stage, but patience is crucial to preserve as much fluffiness as possible. Add the aquafaba in about thirds, gently incorporating each portion with a spatula using a folding motion (cutting through the center and folding it over). Avoid vigorous stirring or whipping, which will deflate the air you’ve worked so hard to create. If you encounter any small chunks, gently press them against the side of the bowl with your spatula to break them up before continuing to fold.
7. Portion and Refrigerate: Once all the aquafaba is combined and the mousse has a light, airy texture, divide it evenly among 4 individual serving jars or containers. Cover them tightly and place them in the refrigerator for at least 1-2 hours to allow the mousse to firm up and set.

Optional Chocolate Ganache (For Extra Indulgence):

8. Make the Ganache: Once your mousse is firm on top, you can prepare the chocolate ganache. Place the chopped chocolate bar in a heat-proof bowl. In a separate microwave-safe container, warm the full-fat canned coconut milk for about 30 seconds in the microwave. It should be warm, but not simmering. Pour the warm coconut milk over the chopped chocolate – do not stir initially! Place a lid or plate over the bowl and let it sit undisturbed for 10 minutes. This allows the residual heat to melt the chocolate.
9. Stir and Top: After 10 minutes, remove the lid and stir the mixture gently until you achieve a smooth, glossy ganache consistency. Carefully spoon some of this ganache over the top of each chilled mousse jar. For an extra touch, sprinkle with a pinch of sea salt.
10. Final Chill: Return the jars to the refrigerator for another 2 hours or even longer. The extended chilling time allows the mousse to fully set and develops a richer, more profound flavor. The longer you wait, the thicker and more delightful it becomes!

What Jars or Containers Work Best?

Presentation is part of the dessert experience, and individual servings make this mousse even more appealing. There are many excellent options for serving and storing your vegan peanut butter mousse:

• Small Mason Jars: These are a personal favorite! Not only do they look charming, but they also make storing extra mousse incredibly simple. They come in convenient individual portions, which is perfect for meal prepping desserts or controlling serving sizes. Try 4oz Mason Jars for a perfect single serving.
• Overnight Oats Jars: These are often slightly larger and can also work well, especially if you prefer a more generous serving. They usually come with lids, which is great for refrigeration. Check out these Overnight Oats Jars.
• Small Glass Ramekins or Dessert Cups: For a more elegant presentation, individual glass ramekins or delicate dessert cups can elevate the experience.

Whatever you choose, ensure the containers have lids or can be tightly covered to prevent the mousse from absorbing refrigerator odors and to maintain its freshness.

Expert Tips For Making The Best Vegan Peanut Butter Mousse

Achieving the perfect, airy texture and rich flavor of this vegan peanut butter mousse is easy with these insider tips:

• Start with a Spotless Bowl: This cannot be stressed enough! Any residual oil or grease in your mixing bowl (especially if using a plastic bowl) will prevent the aquafaba from whipping into stiff peaks. Use a metal or glass bowl and ensure it’s sparkling clean and completely dry.
• Patience is a Virtue (with Aquafaba): While aquafaba cannot be over-whipped, it does take time to reach truly stiff peaks. Don’t rush the process! Using a stand mixer is highly recommended as it automates this step and saves you time and effort. If using a hand mixer, be prepared to whisk for 10-15 minutes. The stiffer the peaks, the more stable and airy your mousse will be.
• Room Temperature for Peanut Butter Mixture: Ensure all ingredients for your peanut butter mixture (peanut butter, coconut cream, etc.) are at room temperature. This helps them combine smoothly and prevents any shocking of the aquafaba mixture, which could lead to deflation.
• Gentle Folding Technique: The key to maintaining the mousse’s characteristic lightness is in the folding. Once the aquafaba is whipped, add it to the peanut butter mixture in small portions (about a third at a time). Use a large spatula to gently fold it in, using a motion that cuts through the center of the mixture and folds it back over. Avoid stirring or whisking vigorously, as this will knock out all the air. Be patient and deliberate with each fold.
• Troubleshooting a Seized Peanut Butter Mixture: If your peanut butter mixture becomes too thick or seizes up after combining, don’t panic! Simply continue whisking it vigorously. Sometimes adding a tiny splash of water (1/2 to 1 teaspoon) can help loosen it up. Keep whisking until smooth again before folding in the aquafaba.
• Don’t Skip the Stabilizers: Cream of tartar and lemon juice are not just optional additions; they play a vital role in stabilizing the aquafaba foam and dramatically speeding up the whipping process. For the best results, use both.
• Quality Chocolate for Ganache: If you’re adding the chocolate ganache, use high-quality chocolate. Since there’s no cream or other ingredients to mask the flavor, the chocolate’s quality truly shines through. Good chocolate might be a bit more expensive, but it’s absolutely worth the investment for a superior taste experience.
• Cool the Ganache: If making a ganache, ensure it’s cooled to room temperature before topping your mousse. Adding warm ganache can melt and deflate your carefully prepared mousse. The double boiler method is excellent for gently melting chocolate without overheating it.
• Ample Chilling Time: While the mousse sets fairly quickly, allowing it to chill for at least 2-4 hours, or even overnight, yields the best results. The flavors deepen, and the texture becomes even more firm and delightful.
• Garnish and Serve: Before serving, consider garnishing your mousse with extra chocolate shavings, a sprinkle of sea salt, chopped roasted peanuts, or a dollop of coconut whipped cream for an extra touch of elegance and flavor.
