How to Make Cottage Cheese Peanut Butter Mousse Step-by-Step
Ready for the easiest dessert recipe ever? Just follow these simple steps for a perfect mousse every time. The key is to trust the process and let the blender do its magic.
- Combine Ingredients: Add the cottage cheese, creamy peanut butter, maple syrup, vanilla extract, and a pinch of salt to a high-speed blender.
- Blend Until Silky: Start blending on low and gradually increase the speed to high. Blend for a full 60-90 seconds, or until the mixture is completely smooth and creamy. Scrape down the sides of the blender once or twice to ensure everything is incorporated.
- Chill and Serve: Pour the mousse into serving glasses or bowls. For the best texture, chill in the refrigerator for at least 30 minutes to allow it to set and thicken.
- Garnish and Enjoy: Top with your favorite garnishes like crushed peanuts, chocolate shavings, or a dollop of whipped cream before serving.
Pro Tips for the Creamiest Mousse Imaginable
Achieving a perfectly smooth, non-grainy texture is the goal. Here are my top tips to ensure your Cottage Cheese Peanut Butter Mousse comes out flawless.
- Use a High-Speed Blender: A powerful blender is crucial for breaking down the cottage cheese curds completely. If you don’t have one, a food processor can work, but you’ll need to blend for longer.
- Don’t Under-Blend: Be patient! Let the blender run for at least a minute. This is the most important step for achieving that signature silky-smooth consistency.
- Stick with Full-Fat: Full-fat cottage cheese has a higher cream content, which is essential for a rich, mousse-like texture.
Delicious Variations to Explore
While this classic peanut butter mousse is divine on its own, it’s also incredibly versatile. Here are a few ideas to get you started.
- Chocolate Peanut Butter Mousse: Add 1-2 tablespoons of unsweetened cocoa powder to the blender for a rich, chocolatey twist.
- Keto-Friendly Version: Swap the maple syrup for a sugar-free liquid sweetener like monk fruit or erythritol.
- Add Some Crunch: Gently fold in mini chocolate chips, chopped peanuts, or cacao nibs after blending for a delightful textural contrast. If you enjoy nutty desserts, you should also try our famous Caramel Pecan Lasagna.
Storing Your High-Protein Mousse
This mousse stores beautifully, making it a great option for meal prep. Transfer any leftovers into an airtight container and store it in the refrigerator for up to 4 days. The mousse will continue to thicken as it chills.
