OMG, You NEED This 5-Minute Keto Peanut Butter Mousse in Your Life!
Okay friends, can we talk about dessert for a hot minute? If you’re anything like me and you’re doing the whole keto thing but still want something that tastes like heaven, I’ve got THE recipe for you.
This keto peanut butter mousse is seriously life-changing. Like, I’m not even being dramatic here – it’s creamy, it’s fluffy, it tastes like a Reese’s cup had a baby with a DQ Blizzard, and get this… it’s totally sugar-free AND ready in 5 minutes flat!
I know what you’re thinking – “Yeah right, another ‘healthy’ dessert that tastes like cardboard.” But hold up! This thing has literally gone viral with over 6 million views on Instagram. People aren’t lying when they say it’s amazing.

Why This Recipe is Actually Perfect
Look, I’ve tried A LOT of keto desserts (some major fails, not gonna lie), but this one hits different:
It’s stupid easy – We’re talking 4-6 ingredients max. If you can use a mixer, you can make this.
Instant satisfaction – Those “I need chocolate NOW” moments? This has your back in under 10 minutes.
It actually tastes good – Like, really good. Not “good for a keto dessert” but actually legitimately delicious.
Super low carb – Only about 3-5 net carbs per serving, so it won’t mess with your macros.
Crazy versatile – Eat it as dessert, use it as frosting, make parfaits, heck I’ve even had it for breakfast (don’t judge me).
Fun fact: This recipe originally came from Leeann at Cut The Wheat, Ditch The Sugar back in 2014, and people are STILL obsessing over it. That’s how you know it’s legit.

The Magic Ingredients (AKA Don’t Mess These Up!)
Here’s the thing – this recipe is simple, but you gotta get the ingredients right or you’ll end up with a sad, gritty mess. Trust me on this one.
Heavy whipping cream – This is what makes it all fluffy and mousse-like. Use about 1/2 to 1 cup depending on how much you’re making. Keep it COLD until you’re ready to use it!
Cream cheese – Go for the full-fat stuff, and please, for the love of all things holy, let it come to room temperature first. Nobody wants lumpy mousse. If you’re feeling fancy, mascarpone works too and makes it extra creamy.
Natural peanut butter (no sugar added) – This is the star of the show! Make sure it says “no sugar added” or your carb count will be totally off. If it’s been in the fridge and it’s all hard, let it warm up a bit first. Oh, and if you can’t do peanuts, sunflower seed butter or almond butter work great too.

Powdered keto sweetener – Listen up, this is CRUCIAL. Do NOT use the granular stuff or your mousse will feel like you’re eating sand. I’m serious! If you only have granular sweetener, just toss it in a food processor until it’s powdery. Brands like Swerve Confectioners, Lakanto, or Wholesome work really well.
Vanilla and a pinch of salt – These just make everything taste better. Don’t skip ’em!
How to Not Mess It Up (Pro Tips Inside!)
Even though this is super easy, there are a few tricks that’ll make yours turn out perfect:
Keep everything cold – Your cream needs to be straight-from-the-fridge cold. Pro move: stick your mixing bowl and beaters in the freezer for 15 minutes before you start. It really makes a difference!
Beat the cream cheese and peanut butter first – Get these totally smooth before you add anything else. Nobody wants chunks in their mousse.
Don’t go crazy with the mixing – Once you add the whipped cream, fold it in gently. If you beat the heck out of it, you’ll deflate all that lovely fluffiness.
Taste as you go – Different sweetener brands have different levels of sweetness, so add a little, taste, then add more if you need it.
If your mousse ends up too thick, just beat in a splash more cream. Too thin? Pop it in the fridge for an hour – it’ll firm up.

Make It Your Own (Because Why Not?)
This is where it gets fun! The basic recipe is amazing, but you can totally customize it:
Chocolate lovers – Melt some keto chocolate chips (Lily’s are my go-to) and drizzle it on top. Or mix in a tablespoon of cocoa powder for chocolate-PB mousse. Mind = blown.
Want some crunch? – Throw in some chopped peanuts, pecans, or even unsweetened coconut flakes.
Coffee vibes – Add a teaspoon of instant coffee for a mocha situation.
Fresh fruit – Top with some raspberries or strawberries for a little tartness.
Get fancy – Layer it in glasses with some keto whipped cream for Instagram-worthy parfaits.
Storage Tips (If You Don’t Eat It All Immediately)
Ha! Leftovers… that’s cute. But seriously, if you somehow have self-control:
In the fridge – It’ll keep for 3-5 days in an airtight container. It gets firmer and more cheesecake-like, which is honestly also amazing.
In the freezer – This is genius – portion it into individual containers and freeze for up to 3 months. When you want some, just let it thaw for 10-15 minutes and boom, you’ve got keto “ice cream.” You’re welcome.
The Nutritional Breakdown
Since we’re all counting macros here, you’re looking at roughly:
- 200-450 calories per serving (depending on size)
- 18-46g fat
- 3-5g net carbs
- 5-8g protein
Pretty solid for something that tastes like dessert from your childhood, right?
When Things Go Wrong (It Happens!)
Gritty texture? – You used granular sweetener instead of powdered. Rookie mistake! Next time, powder that stuff first.
Too thick? – Add more cream, a tablespoon at a time.
Too runny? – Your cream wasn’t cold enough, or you didn’t whip it properly. Chill the whole thing for an hour.
Weird aftertaste? – Some sweeteners are finicky. Lakanto and Wholesome tend to have the least weird aftertaste, in my experience.
Bottom Line
Look, I’m not saying this mousse will change your life, but… okay fine, it might change your life a little. It’s proof that eating keto doesn’t mean you have to give up all the good stuff.
Fair warning though – this stuff is dangerously good. Like, “eat the whole bowl while binge-watching Netflix” good. Maybe portion it out ahead of time if you have zero self-control like me.
Go make this! Right now! Your taste buds will thank you, your macros will stay happy, and you’ll have a new go-to dessert that takes literally no effort. What are you waiting for?
