Chocolate and peanut butter is one of the most beloved flavor pairings. When I began keto I missed peanut butter cups, but then I discovered fat bombs. There are many flavors—lemon, strawberry, mint—but my first experiment was naturally peanut butter and chocolate. I adapted a nut butter cacao bomb recipe to perfect the balance of creaminess and chocolatey flavor.

What is a keto fat bomb?

Fat bombs are bite-sized snacks high in fat and low in carbohydrates. Often made with nut butters and coconut oil, they can be sweet or savory. Because fats are digested more slowly than carbs, fat bombs help stave off hunger and support keto macros when used alongside nutritious, low-carb meals.

How many fat bombs can you eat per day?

That depends on your daily calorie and macronutrient targets. Fat bombs are a convenient way to reach fat goals on keto, but they shouldn’t replace balanced meals rich in vegetables and protein. These chocolate peanut butter fat bombs are small; many people find one a day is sufficient, though you may want more depending on your needs and appetite. Tracking intake with an app that lets you set macros and add custom recipes can be helpful when fitting treats into a keto plan.

Can fat bombs take you out of ketosis?

Prepared as directed, these fat bombs are unlikely to disrupt ketosis. Each serving is low in carbs and primarily fat, making them a suitable occasional snack on a ketogenic regimen.

How to Make Peanut Butter Chocolate Fat Bombs

Ingredients

• 1/4 cup organic coconut oil
• 1/4 cup heavy cream
• 3 tbsp unsweetened cocoa powder (cocoa or roasted cacao)
• 2 tbsp natural peanut butter (no added sugar)
• 4 tsp powdered erythritol or powdered monk fruit sweetener (e.g., powdered Swerve)

Directions

1. Gently melt the coconut oil in a small saucepan over very low heat. You can also melt it in short bursts in the microwave.
2. Add the heavy cream, cocoa powder, peanut butter, and powdered sweetener. Whisk until the mixture is completely smooth and glossy.
3. Using a tablespoon, portion the mixture into 12 silicone molds, silicone liners, or mini muffin tins.
4. Chill in the refrigerator for about an hour, or in the freezer for 20–30 minutes, until set.
5. Pop the fat bombs from the molds and store them in an airtight container in the refrigerator for up to two weeks, or freeze for longer storage. Because they contain coconut oil, they will soften quickly at room temperature and should be kept chilled.

Notes and Tips

• Use natural peanut butter with no added sugar to keep carbs low.
• Adjust sweetness to taste—liquid sweeteners change texture, so powdered sweetener gives the best consistency.
• Portion by tablespoon for evenly sized servings and consistent nutrition.
• Store chilled. If frozen, thaw briefly in the refrigerator before eating to avoid excessive hardness.
