This velvety peanut butter mousse turns basic pantry staples into a decadent treat that feels like it's from an upscale eatery. The fluffy, smooth consistency paired with deep peanut butter notes creates a wonderful balance that'll fix any dessert craving without spending hours cooking.

Ingredients
- Smooth peanut butter: Delivers the core flavor punch. Go for a good quality brand without too many extras for the nicest taste and feel.
- Cream cheese: Gives a zingy twist that cuts through the sweetness. Don't forget to let it soften completely for a smooth mousse.
- Powdered sugar: Adds sweetness while keeping everything smooth. Don't use regular sugar as it'll make your mousse feel gritty.
- Heavy cream: Builds the fluffy texture when beaten. Make sure it's cold from the fridge to get the best volume.
Step-by-Step Instructions
- Mix the base:
- Throw together your peanut butter, cream cheese, and powdered sugar in a big bowl. Mix until totally smooth with no traces left unmixed. This makes your flavor base, so take your time making sure it's all blended into a silky mix.
- Whip the cream:
- In another clean bowl, beat the heavy cream until it forms stiff peaks. This typically needs about 3 minutes with an electric mixer. You'll know it's ready when the cream holds its shape firmly after lifting the beaters but still looks shiny not dry or bumpy.
- Combine carefully:
- Put roughly a quarter of your whipped cream into the peanut butter mix and stir gently to thin the base. This first bit makes folding in the rest easier without flattening it. Then fold in half of what's left using a rubber spatula with a soft down and over motion until just mixed.
- Finish the mousse:
- Add the last bit of whipped cream and fold just until you can't see white streaks anymore. Don't overmix or you'll lose all that fluffiness. The end product should be light and airy with a consistent look.
- Pipe and serve:
- Scoop your finished mousse into a piping bag with a fancy tip. Squeeze into serving glasses or small jars for a pretty presentation. You can eat it right away but it tastes even better after chilling for at least 30 minutes.

The first time I gave this mousse to my mom she couldn't believe I hadn't spent forever making it. Seeing her face when I told her how simple it was is something I'll always remember fondly. Now she whips it up all the time for her bridge club friends.
Texture Perfection
Getting the perfect mousse texture depends on two key steps. First, your cream cheese must be completely soft before mixing or you'll end up with tiny bumps all through your mousse. Second, you've got to whip your heavy cream just right—stiff peaks but not further. If you beat it too much, it gets grainy and will mess up your smooth dessert. If you're new to whipping cream by hand, stop often to check how it's coming along.
Creative Variations
You can change up this mousse recipe in so many ways. For a chocolate peanut butter twist, mix in 1/4 cup of melted and cooled dark chocolate. Using almond butter creates a fancier flavor that works really well with a little sea salt sprinkled on top. Want something fun? Layer the mousse with crushed graham crackers and some raspberry sauce for a broken-down PB&J that'll make everyone happy, no matter their age.

Elegant Serving Ideas
Make this simple mousse look fancy by thinking about how you serve it. Put layers in clear glasses with fresh berries and crushed peanuts to add different textures. For dinner parties, put small amounts in espresso cups with a tiny chocolate-covered pretzel on top. During hot months, freeze the mousse in popsicle molds for a cool treat that kids and grown-ups will both love. There's no end to what you can do with this adaptable dessert.
