What Is A Fat Bomb?

Fat bombs are high-fat, low-carb snacks that can be used to increase fat intake for those following a ketogenic diet (keto).

They are small snacks that pack a punch of healthy fats and often contain some form of protein too. Fat bombs provide the keto dieter with an easy way to hit their daily macros and stay full between meals.

Ketogenic diets require a high fat and very low carbohydrate intake in order to promote fat loss caused by a metabolic state of ketosis.

And one of our favorite fat bombs to make is the Peanut Butter Fat Bomb! This tasty treat is full of keto-friendly ingredients, flavorful peanut butter, and a creamy texture. Not only do these fat bombs fit into a low-carb keto diet, they are also gluten free with vegan, nut free, and paleo substitutions included.

  • Quick and easy to make in 15 minutes.

  • Low-carb chocolate peanut butter bombs balance out a sugary holiday table and can satisfy a sweet tooth without the sugar rush post-holiday season.
  • Perfectly portioned, portable, pick-me-ups for pre/post workouts, surviving an afternoon slump or serving for dessert (even if you’re not on a diet).

Keto Bombs Ingredients

  • Unsalted butter: You can substitute coconut oil if you need a dairy-free alternative. It will yield a slightly different flavor and have a slightly lower melting point but will still be very delicious.
  • Powdered swerve
  • Unsweetened cacao powder: I used Hershey’s Special Dark Unsweetened 100% Cacao. You can omit the cacao for a less chocolatey version.
  • Vanilla extract
  • Sea salt
  • Unsweetened peanut butter
  • Sugar free chocolate chips

Substitutions and Additions

  • Swap The Sweetener: Swerve is a low-glycemic sweetener made with erythritol. I use this sweetener because it is available at most grocery stores, but if you have a favorite powdered low-carb sweetener that you would prefer to use you can absolutely substitute it, just be sure that it measures 1:1 with regular powdered sugar. Granulated sweetener is not recommended because it will not fully dissolve and will create a grainy texture. 
  • Choose Your Chocolate: I like Lily’s or Bake Believe brand sugar-free chocolate chips and have tested both in this recipe. You can use dark, semi-sweet, milk, or even white chocolate for these fat bombs based on your preference. If using white chocolate or even milk chocolate, consider omitting the cocoa powder so that it doesn’t overpower the flavor of these types of chocolate. 
  • Pick Your Peanut Butter/Nut Butter: Select your favorite creamy peanut butter that has no added sweetener. If the peanut butter you are using is salted, consider reducing the salt added to this recipe. If you cannot have peanuts, almond butter and cashew butter are perfectly paleo. For an allergen-friendly and nut-free snap, simply swap out the peanut butter for sunflower seed butter, tahini, or soy nut butter.
  • Vegan Version: This recipe can easily be made vegan by substituting the butter 1:1 for coconut oil and selecting a package of dairy-free sugar-free chocolate chips (Lily’s 55% Dark Chocolate Chips and Bake Believes 55% Cacao Dark Chocolate Chips are both vegan-friendly).

How to Make Peanut Butter Fat Bombs

  1. Make The Fat Bomb Mixture: Whisk the cacao powder, powdered sweetener, vanilla extract, and salt into melted butter. Stir until there are no lumps, lower the heat and mix in the peanut butter until fully melted. Add the chocolate chips and stir continuously until the chocolate chips have fully melted and the mixture is a smooth.
    Pro Tip: Once the chocolate has melted, immediately remove from heat to prevent the it from getting too hot. 
  2. Pour Into The Pan: Pour the mixture into a silicone mini muffin pan or baking pan lined with parchment paper. Sprinkle with flaky sea salt chill for about 3 hours or overnight to set.
    Pro Tip: If using a baking dish, pour the mixture and then spread it evenly using a rubber spatula.
  3. Serve: Remove the fat bombs from the molds. You can allow them to thaw for several minutes at room temperature or enjoy them straight from the fridge. Enjoy!

What Kind Of Chocolate Is Best For Fat Bombs?

Any type of sugar-free chocolate chip will work in this recipe. I prefer brands that use a combination of erythritol and stevia or monk fruit to sweeten. If you are using mini chocolate chips or baking chocolate, measure by weight and not volume. You can use any variety you would like including milk, semi-sweet, dark, or white. I used 55% dark chocolate chips.

Tips for Making the Best Fat Bombs

  • Fat bombs are intended to be high in fat, so I prefer to use high-quality fat in these types of recipes. A good quality butter, like that from pasture-raised cows, not only contributes to a rich and creamy flavor but also has additional health benefits. Good butter is totally worth splurging on in this recipe!
  • The cacao powder adds richness to the chocolate flavor in this recipe. Be sure to select unsweetened cacao or cocoa powder. If you prefer a slightly less intense chocolate flavor you can omit this ingredient altogether. Consider omitting if you prefer milk or white chocolate and plan to use one of these varieties of chocolate in the recipe.
  • This recipe may get too salty if you are using salted butter, salted peanut butter, and/or regular table salt (which tends to be saltier than sea salt). If you are using any of these ingredients or are particularly sensitive to salt, it may be best to salt to taste. Generally, people who are following a ketogenic diet require more sodium than someone following a regular diet, so a little extra salt can be a tasty way to get a boost of electrolytes. 
  • Keep in mind that erythritol and other low carbohydrate sweeteners tend to have a lower melting point than sugar which makes them easier to burn. Keep the heat low when making these fat bombs and only keep the saucepan on the heat for long enough to melt the chocolate.
  • Powdered swerve tends to clump fairly easily. To get a smooth, fudgy texture be sure to sift the powdered sweetener before adding it to the butter.
  • If you prefer a stronger peanut butter flavor, feel free to omit the cacao powder!

How to Store Chocolate Peanut Butter Fat Bombs

  • To Store: Store these fat bombs in an airtight container in the fridge for 1-2 weeks.
  • To Freeze: Freeze these fat bombs in an airtight container for up to 3 months in the freezer.

Frequently Asked Questions

How to store these fat bombs?

Because these fat bombs have a relatively low melting point, they get soft when left at room temperature for too long. For storage, place the fully set treats in a large Ziploc bag or airtight container and store them in the fridge for 1-2 weeks. They have a great texture straight out of the fridge or can be softened at room temperature for several minutes before enjoying.

Can I freeze this recipe?

Absolutely! This recipe freezes well. Freeze these fat bombs in an airtight container and store them for up to 3 months in the freezer. Thaw in the fridge for 24 hours or at room temperature for 30 minutes. 

How Many Fat Bombs Can You Eat on Keto?

The number of fat bombs that you can eat on a keto diet depends on how many carbs you are allowed to consume throughout your day. With only 3 net carbs per serving, you can enjoy these fat bombs in moderation without exceeding your daily macro allowance. Because they are filling and high in healthy fats, one or two should keep you satiated.
