Peanut Butter (natural, creamy) – Adds that signature flavor and rich, satisfying mouthfeel.
Sweetener of Choice – Maple syrup, honey, or for a low-carb treat, allulose or monk fruit work great.
Vanilla Extract – For that bakery-style aroma and flavor.
Salt (optional) – Just a pinch helps balance the sweetness and bring out the peanut flavor.
Milk or Heavy Cream – A splash if needed for blending and silky smooth texture.
Toppings – Think dark chocolate chips, chopped nuts, or more peanut butter because why not?

How to Make Cottage Cheese Peanut Butter Mousse

Step 1: Blend it All Together

Toss the cottage cheese, peanut butter, sweetener, vanilla, and salt into a blender or food processor. Start blending on medium speed.

Pause after 30 seconds to scrape down the sides, then blend again until completely smooth and mousse-like. If it’s too thick to blend easily, add 1–2 tablespoons of milk or cream until it moves more freely.

Step 2: Taste and Adjust

Give it a taste this is where the magic happens. Too tangy? Add a bit more sweetener. Want it extra rich? Add another spoonful of peanut butter (go on, you deserve it).

Step 3: Chill (You and the Mousse)

Transfer the mousse to ramekins or small jars and refrigerate for at least 30 minutes. This helps it set to that perfect whipped texture and gives the flavors time to marry.

Step 4: Top and Serve

Before serving, add your favorite toppings: chopped peanuts for crunch, a sprinkle of dark cottage chocolate chips for indulgence, or a drizzle of peanut butter for flair.

A Little Story from My Spoon to Yours

The first time I made this, I did it on a whim after a peanut butter craving struck late at night (the kitchen light was off, it felt like a scene out of a dark cottage fairytale). I blended everything in silence, half-hoping it’d flop only to take a bite and whisper, “Oh wow.” Since then, it’s become my not-so-guilty indulgence. Even my kids, who claim to “hate cottage cheese,” ask for second helpings.

Frequently Asked Questions

Can I use low-fat cottage cheese?

You can, but the texture might not be as creamy. Full-fat is best for that thick mousse-like consistency.

Is this keto-friendly?

Yes! Just use a keto-approved sweetener and skip the honey or maple syrup. Pair it with keto peanut butter cookies for a double win.

Can I freeze this mousse?

Yes, but only for short-term freezing (about a week). Let it thaw in the fridge for best texture, or eat it semi-frozen like an ice cream treat.

What if I don’t have a blender?

A food processor works too! Just make sure you blend until the curds in the cottage cheese are fully smooth.

Do mice like peanut butter?

Oh, absolutely. It’s often used as bait in traps. But let’s keep this mousse for you, not your unexpected houseguests.

Can I add chocolate?

Heck yes. Add cocoa powder for a chocolate-peanut butter twist, or top with dark chocolate shavings for a sophisticated touch.

Is this high in protein?

Definitely. Between the cottage cheese and peanut butter, you’re getting a solid protein hit. Add some protein powder dessert mix if you want to up it even more.

What toppings work best?

Chopped nuts, chocolate chips, granola, shredded coconut, or extra peanut butter are all great. Basically, anything you’d love on a peanut butter cup.
