Let Me Tell You Why This Mousse Is Always in My Fridge…

Okay, real talk — I’m obsessed with this Cottage Cheese Peanut Butter Mousse. It’s creamy, naturally sweet, full of protein, and takes literally 5 minutes to make (with one hand, if you’re wrangling toddlers :). I whip this up when I want something sweet after lunch, or when my kids ask for a “treat” but I want them to eat something real.

It’s just 6 ingredients, no baking, and no fancy steps. Just blend, chill (if you can wait), and savor

How to make Cottage Cheese Peanut Butter Mousse

Ingredients You”ll need

Here’s what you’ll need — and why each one matters:

• 1 cup full-fat cottage cheese – This is your creamy, protein-packed base. Go full-fat for the smoothest texture.
• ¼ cup natural peanut butter – Creamy, unsweetened, and loaded with healthy fats. It gives that rich nutty flavor kids love.
• 2 tbsp sweetener – I use honey or maple syrup, but monk fruit or allulose works great too. Totally customizable.
• 1 tsp vanilla extract – Just a little makes it feel more dessert-like. Trust me.
• ¼ tsp salt (optional) – If your PB isn’t salted, this brings balance.
• 1–2 tbsp milk or heavy cream (as needed) – Only if it’s too thick to blend — go by texture.

Toppings (optional but highly recommended):
Chopped peanuts, dark chocolate chips, or a drizzle of peanut butter on top. Because moms deserve toppings.

Step-by-Step Instructions

Start by grabbing your blender or food processor — either one works, as long as it’s strong enough to smooth out the cottage cheese. Add 1 cup of full-fat cottage cheese straight into the blender. No need to strain it; just use it as-is from the container.

Now measure out ¼ cup of peanut butter. Use a natural, creamy one with no added sugar. Spoon that right into the blender with the cottage cheese.

Next, it’s time to sweeten things up. Drizzle in 2 tablespoons of your favorite sweetener — honey, maple syrup, or a sugar-free option like monk fruit. I’ve tried all three and they each bring something a little different, so go with what you have on hand.

Add 1 teaspoon of vanilla extract for warmth, and if your peanut butter isn’t salted, sprinkle in ¼ teaspoon of salt to balance the flavors. Don’t forget to scrape down the sides as you go — peanut butter loves to cling to the blender wall.

Blend everything on high until it’s smooth and creamy. Depending on your blender, this might take 30 to 60 seconds. If the mixture looks a bit too thick or isn’t moving well, go ahead and add 1 to 2 tablespoons of milk or heavy cream — just enough to loosen it up. Blend again until you get that rich mousse-like texture.

Once it’s smooth, taste it. If you want a little more sweetness, you can stir in another drizzle of honey or maple syrup. Totally up to you.

Spoon the mousse into small jars or bowls. If you’re planning to serve it later, pop them into the fridge for 15–20 minutes to firm up a little more. Otherwise, it’s ready to go right now.

Finish with your favorite toppings — a few chopped peanuts for crunch, dark chocolate chips for something sweet, or a swirl of peanut butter for the peanut butter lovers in your house.

And that’s it. A creamy, protein-packed mousse in five minutes flat.

Cottage Cheese Peanut Butter Mousse Recipe Tips for Success

Use full-fat cottage cheese if you can. I’ve tested this mousse with low-fat versions, and while it still works, the texture isn’t quite as smooth and the flavor’s a little more “tangy.” Full-fat gives you that velvety, dessert-like finish that makes this feel like a treat.

Make sure your peanut butter is soft and creamy. If it’s been sitting in the fridge, let it come to room temperature first. Cold peanut butter is harder to blend and can cause the mousse to turn out a bit lumpy.

Don’t skip the salt unless your peanut butter is already salted. A tiny bit really makes the sweet and nutty flavors pop. You don’t need much — just a pinch goes a long way.

If your blender is struggling to get things going, stop and scrape down the sides. A silicone spatula works great for this. And don’t be afraid to add a tablespoon or two of milk or cream if the mixture is too thick — it won’t water anything down, it just helps everything blend smoothly.

Want to mix things up? Try adding a tablespoon of unsweetened cocoa powder for a chocolate version, or swirl in a bit of sugar-free jam before serving. My kids love it with raspberry.

And if you’re making this ahead of time, it holds up really well in the fridge for a couple of days. Just store it in an airtight container and give it a quick stir before serving.

Perfect Pairings

This mousse is great with:

• Sliced apples or strawberries for dipping
• A warm cup of homemade Herbal chai latte
• Crumbled over banana oat muffins
• As a lunchbox treat in small reusable containers

if you’re putting together a snack tray or planning a lunchbox, try pairing it with something comforting and carb-friendly. It’s especially delicious with fresh fruit or a slice of something like this Fage Banana Bread — soft, slightly sweet, and made with protein-packed Greek yogurt.

Frequently Asked Questions

1. Can I use low-fat cottage cheese?
Yes, you can use low-fat cottage cheese, but the texture will be less creamy. For the best mousse-like consistency and rich flavor, full-fat is the way to go.

2. My mousse came out too thick. What should I do?
Just add a splash of milk or heavy cream—start with 1 tablespoon and blend again. You can keep adding small amounts until you reach the texture you like. Some blenders also work better with a little extra liquid.

3. Can I make this mousse ahead of time?
Absolutely. This mousse keeps well in the fridge for 2 to 3 days in a sealed container. If it thickens up too much while chilling, give it a quick stir before serving.

4. Do kids like it?
Definitely. It’s creamy, lightly sweet, and has that peanut butter flavor most kids love. You can even pack it in a small container for lunchboxes or after-school snacks.

5. Can I swap out the peanut butter?
Yes. You can use almond butter, cashew butter, or even tahini for a different flavor. Just make sure it’s smooth and unsweetened, and adjust the sweetener to taste.
