Keto Peanut Butter Chocolate Fat Bombs are little bites of creamy, rich goodness that combine the nutty flavor of peanut butter with the smooth sweetness of chocolate. These low-carb treats are perfect for anyone looking to satisfy a sweet tooth without breaking their keto goals. They’re super easy to make and packed with healthy fats that keep you feeling full and energized.
I love making these fat bombs when I need a quick snack that feels like a treat but won’t kick me out of ketosis. They’re great for a midday pick-me-up or a little dessert after dinner. My favorite part is how the peanut butter and chocolate melt together in your mouth—so simple, yet so satisfying. Plus, you can easily tweak the recipe to add a bit more crunch or a sprinkle of sea salt on top for extra flavor.
When I serve these, I like to keep a batch in the fridge so they’re always ready to enjoy. They’re perfect for packing in a lunchbox or grabbing on the go. Friends who try them always ask for the recipe, which is such a compliment because usually, people expect a treat to be full of sugar and hassle. These fat bombs make sticking to a low-carb lifestyle a little sweeter and a lot more fun!
Key Ingredients & Substitutions
Natural Peanut Butter: Look for no sugar added and smooth texture for easy mixing. If peanut allergies are a concern, try almond or sunflower seed butter instead. They give a different but equally tasty flavor.
Coconut Oil: This is great for helping the fat bombs set firmly. You can use cocoa butter or MCT oil as alternatives, but coconut oil offers a nice, mild flavor that pairs well with chocolate.
Unsweetened Cocoa Powder: It gives rich chocolate flavor without sugar. You could swap with raw cacao powder if you want a slightly more intense and less processed option.
Powdered Erythritol: This keto-friendly sweetener dissolves well, creating a smooth texture. Monk fruit sweetener or stevia blends also work, though they might slightly change the taste.
Vanilla Extract & Sea Salt: These small touches boost flavor and balance the sweetness. Don’t skip the sea salt—it really highlights the peanut butter and chocolate.
How Can I Get My Fat Bombs Firm and Smooth?
Melting and mixing the peanut butter and coconut oil thoroughly is key. Coconut oil needs to be liquid but not hot, or your mixture can separate.
- Microwave in short bursts or gently melt on the stove to avoid overheating.
- Whisk well after adding cocoa powder and sweetener to blend evenly without lumps.
- Pour immediately into molds for clean edges.
- Freeze for at least one hour to let them fully harden—don’t rush this step.
For extra smoothness, sift your cocoa powder and powdered sweetener beforehand. This helps avoid grainy texture and makes the final treat silky and easy to enjoy.
Equipment You’ll Need
- Microwave-safe bowl – perfect for gently melting peanut butter and coconut oil without a mess.

Can I Use Frozen Peanut Butter for This Recipe?
It’s best to use peanut butter at room temperature to ensure smooth mixing. If your peanut butter is chilled or slightly firm, warm it gently in the microwave for 10-15 seconds before combining with coconut oil.
How Should I Store These Fat Bombs?
Store the fat bombs in an airtight container in the refrigerator for up to 2 weeks or in the freezer for up to 3 months. Keep them chilled to maintain their firm texture.
Can I Substitute Coconut Oil with Something Else?
Yes! You can use cocoa butter or MCT oil instead of coconut oil. Just keep in mind cocoa butter may change the flavor slightly and MCT oil will soften the texture a bit.
Are These Fat Bombs Suitable for Nut Allergies?
If you have nut allergies, swap peanut butter with sunflower seed butter or pumpkin seed butter to keep it nut-free while still enjoying these tasty treats.
