About This Recipe

Fat bombs are one of the most iconic keto snacks — and for good reason. They’re quick to make, satisfy sweet cravings, and deliver the perfect balance of fats to keep you full and energized. These Keto Chocolate Peanut Butter Fat Bombs are a classic combination of flavors that feels indulgent while staying 100% low-carb.

The base blends creamy peanut butter with coconut oil for richness, then gets sweetened with a keto-friendly sweetener and layered with cocoa for a chocolatey kick. The texture is smooth, melt-in-your-mouth, and just the right amount of decadent without being overly sweet.

Nutritionally, fat bombs are designed to be keto powerhouses. They’re high in healthy fats, low in carbs, and perfectly portioned for when you need a little energy boost or want to curb hunger between meals. These bites are also no-bake, so they come together in minutes and store beautifully in the fridge or freezer.

Inspired by the timeless pairing of chocolate and peanut butter, this recipe proves you don’t need sugar to enjoy your favorite flavor combo. They’re simple, convenient, and guaranteed to become a go-to in your keto snack rotation.

FAQ

Can I use almond butter instead of peanut butter?
Yes — almond butter works just as well for a different flavor.

Do I have to use coconut oil?
Coconut oil helps them set. Butter or ghee can work, but the texture will be softer.

Can I make these sweeter?
Adjust the sweetener to taste, or add a drop of liquid stevia.

Do they need to stay cold?
Yes — they melt at room temperature, so store in fridge or freezer.

Variations & Substitutions

Use almond butter or sunflower seed butter for a nut-free option.
Add shredded coconut for texture.
Coat with melted sugar-free chocolate for a firmer shell.
