Ingredients You’ll Need
The magic of this Cool Whip and Peanut Butter Mousse lies in its simplicity. Each ingredient plays a crucial role in delivering that luscious texture and punch of flavor, but you won’t need a pantry full of extras to pull it off.
- Peanut butter powder: Using powdered peanut butter keeps the mousse light and fluffy without overwhelming it with oiliness.
- Cool Whip, light: This brings in the creamy, airy base that makes the mousse so delightfully smooth.
- Water: Just enough to rehydrate the peanut butter powder and blend everything seamlessly.
- Optional sugar free chocolate syrup: A perfect finishing touch to add a hint of decadence without extra sweetness.
How to Make Cool Whip and Peanut Butter Mousse
Step 1: Whisk the Peanut Butter Powder
Start by mixing your peanut butter powder with three tablespoons of water. Whisk this until it’s completely smooth and lump-free. This step is crucial because it ensures your peanut flavor is evenly distributed throughout the mousse, giving you consistent, delicious bites every time.
Step 2: Fold in the Cool Whip
Next, gently fold the peanut butter mixture into one cup of light Cool Whip. Folding rather than stirring helps keep the mousse airy and light, preserving that fluffy texture we all love. Be gentle and patient—you want to preserve the mousse’s cloud-like softness.
Step 3: Portion and Freeze
Scoop or pipe the mousse into muffin cups or dessert glasses. This step is where a piping bag can be your best friend, creating beautiful little swirls that look as decadent as they taste. Once portioned, pop them in the freezer to firm up. Freezing intensifies the mousse’s texture and flavor, creating a delightfully cool treat.
Step 4: Add Optional Chocolate Drizzle
For an extra layer of flavor, drizzle sugar free chocolate syrup on top before serving. This step is optional but highly recommended if you love a little chocolate-peanut butter combo without adding extra calories or sugar.
How to Serve Cool Whip and Peanut Butter Mousse

Garnishes
A sprinkle of chopped peanuts, a dusting of cocoa powder, or even a few fresh berries can take your mousse from simple to spectacular. These little extras not only add contrasting textures but also brighten the dessert’s appearance.
Side Dishes
Pair this mousse with crunchy graham crackers, a handful of salted pretzels, or even fresh apple slices for a delightful balance of creamy and crunchy. It’s a wonderful way to turn this mousse into a mini dessert platter that everyone will adore.
Creative Ways to Present
Serve your Cool Whip and Peanut Butter Mousse in mini mason jars, layered with crushed cookies or jelly for a fun twist. Or be adventurous and pipe it into chocolate cups for an elegant, crowd-pleasing presentation that’s as fun to look at as it is to eat.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator for up to three days. The mousse will soften slightly but still maintain its delicious, fluffy texture. Give it a gentle stir before serving if separation occurs.
Freezing
This mousse holds up beautifully in the freezer. Keep it in airtight containers or the muffin cups you used for serving, covered well to prevent freezer burn. When frozen, it turns into a lovely, chilled treat that’s perfect for warm days.
Reheating
Reheating isn’t really necessary or recommended since this is a mousse meant to be enjoyed cold or frozen. If you want to soften it slightly after freezing, just leave it out at room temperature for 10-15 minutes before serving.
FAQs
Can I use regular peanut butter instead of peanut butter powder?
You could, but regular peanut butter is much heavier and oilier. It will change the texture of the mousse, making it denser and less fluffy, so peanut butter powder is your best bet for the light mousse texture.
Is Cool Whip the same as whipped cream?
Cool Whip is a whipped topping that’s stabilized and lasts longer in the fridge than whipped cream. It also has a lighter texture and is easier to work with for this mousse recipe, but you can substitute whipped cream if desired for a fresher, less processed option.
How long does the mousse need to freeze before serving?
About 2 to 3 hours in the freezer is enough to set the mousse nicely. If you want it firmer, feel free to leave it overnight. Just remember to cover it properly to avoid freezer smells.
Can I make this mousse sugar-free?
Absolutely! Both the peanut butter powder and Cool Whip light options often come with varieties that have no added sugar, and by using sugar free chocolate syrup, you can keep the whole dessert low in sugar and guilt-free.
What is the best way to pipe the mousse?
Use a large star or round piping tip with a disposable or reusable piping bag. This helps create pretty swirls and makes portioning easier, especially for gatherings or fancy presentations.
