Crisp Keto No Bake Peanut Butter Cookies
These keto no bake peanut butter cookies deliver a salty, thick crunch that shatters in your mouth before giving way to soft marshmallows. They take just twenty minutes of active prep, leaving you with sweet rewards in the fridge for the entire week.
The Secret to the Crunch
- Cocoa butter flow: Melting in a bit of cocoa butter thins the coating. It wraps every piece of cereal evenly without turning into a heavy paste.
- Temperature control: Letting the chocolate cool slightly is crucial. It keeps those soft marshmallows intact instead of turning them into a gooey puddle.
- A hit of salt: That tiny pinch of kosher salt cuts straight through the sweetness. It balances the entire profile.

Nailing These Keto No Bake Peanut Butter Cookies
Set up a double boiler on the stove. Keep the water at a gentle simmer and don’t let the bowl touch the water. Add the white chocolate, peanut butter, and cocoa butter.
Stir constantly for about three to five minutes. You want everything to look totally fluid and glossy. Pull the bowl off the heat and stir in the vanilla and salt.
You need to let this bowl sit at room temperature for about ten minutes. If the chocolate is too hot, the marshmallows will melt into a sticky mess. Once the mixture cools slightly, dump in the crisp protein cereal and marshmallows.
Fold everything gently with a rubber spatula until every piece is coated. Drop mounds onto a parchment-lined baking sheet. Sprinkle sugar-free dark chocolate chips evenly over the tops.
This makes portioning out your low carb peanut butter dessert fast. Transfer the pan to the fridge and chill for 45 minutes until completely firm.
Tricks for the Best Batch
- Watch the water: Keep all steam and water away from your melting bowl. One stray drop will make the white chocolate seize into a gritty mess.
- Switch up the nut butter: Almond butter works beautifully here if you want an earthier flavor profile.
- Storage details: Keep these sugar free avalanche cookies in an airtight container in the fridge. They hold their crunch for up to five days.

Description
A sweet and salty combination of creamy peanut butter, sugar-free white chocolate, crisp protein cereal, and soft marshmallows. These easy no-bake drop cookies come together quickly and set up perfectly in the fridge for a crunchy, chewy treat.
Ingredients
Coating Mixture
- 6 oz (170g) sugar-free white chocolate chips
- 1/4 cup (60g) creamy unsweetened peanut butter
- 3/4 oz (21g) food-grade cocoa butter, chopped (about 1 1/2 tablespoons)
- 1/2 teaspoon (2.5ml) vanilla extract
- 1/8 teaspoon (0.5g) fine kosher salt
Mix-Ins and Topping
- 2 cups (60g) keto-friendly crisp protein cereal
- 1 cup (50g) sugar-free marshmallows, mini or chopped
- 2 tablespoons (30g) sugar-free dark chocolate chips
Instructions
- Prepare the baking sheet: Line a large rimmed baking sheet with parchment paper or a silicone baking mat. Set it aside.
- Set up a double boiler: Fill a medium saucepan with 1 to 2 inches of water and bring to a gentle simmer over medium-low heat. Place a heatproof glass or metal bowl over the saucepan, ensuring the bottom of the bowl does not touch the simmering water.
- Melt the coating: Add the sugar-free white chocolate chips, creamy peanut butter, and chopped cocoa butter to the heatproof bowl. Stir continuously for 3 to 5 minutes, until the ingredients are completely melted, smooth, and glossy. Remove the bowl from the heat.
- Flavor and cool: Stir the vanilla extract and kosher salt into the melted white chocolate mixture. Let the bowl sit at room temperature for 8 to 10 minutes to cool slightly. The mixture should still be fluid but no longer hot to the touch.
- Fold in the mix-ins: Gently fold the crisp protein cereal and sugar-free marshmallows into the cooled white chocolate mixture using a rubber spatula. Stir gently until all the pieces are evenly coated.
- Portion the cookies: Use a cookie scoop or two spoons to drop roughly 2-tablespoon-sized mounds of the mixture onto the prepared baking sheet. Sprinkle the tops evenly with the sugar-free dark chocolate chips.
- Chill to set: Transfer the baking sheet to the refrigerator and chill for 45 to 60 minutes, or until the cookies are completely firm to the touch.
Notes
Why It Works
- Cocoa butter subtly thins out the melted white chocolate, ensuring it coats the cereal evenly without turning into a heavy, unworkable paste.
- Cooling the melted mixture before adding the marshmallows prevents them from melting into a sticky mess, preserving their soft, chewy texture.
- Adding a small pinch of kosher salt cuts through the intense sweetness of the sugar-free white chocolate and marshmallows, balancing the flavor profile.
Common Pitfalls to Avoid
- Seizing chocolate: Keep all water and steam away from the inside of the melting bowl; even a single drop of water can cause the sugar-free white chocolate to turn gritty and seize.
- Marshmallow melting: Do not skip the cooling step before adding the marshmallows. If the white chocolate is too hot, the marshmallows will dissolve and change the intended texture of the cookies.
- Dry cookies: Measure the cereal carefully. Adding too much cereal will leave the mixture dry and prevent the cookies from holding together.
Variations
- Almond Butter Avalanche: Swap the peanut butter for creamy, well-stirred unsalted almond butter.
- Nutty Crunch: Replace half a cup of the crisp cereal with lightly toasted, chopped pecans or walnuts for an earthier crunch.
Allergy Alert

The Final Word
These hit the spot when I need a crunchy snack, but I always ask: how did your body respond to this? If you want a softer, spoonable chilled treat tomorrow, try my vanilla chia pudding. Or, for a warm and fruity contrast, my triple berry cobbler hits completely different notes.
