Easy Keto Peanut Butter Fat Bombs (Chocolate Swirl)

Introduction

The combination of peanut butter and chocolate is something that quite frankly never gets old. It’s always been one of my favorite combinations growing up as a kid! So, it’s no surprise that this blog contains a bunch of peanut butter and chocolate keto desserts (sorry not sorry!).

These easy keto peanut butter fat bombs are the quickest of the lot. The base is melted coconut oil and cocoa, then peanut butter gets swirled directly into the chocolate. There is no baking and only about five minutes of active work before the freezer takes over.

Why These Peanut Butter Fat Bombs Are So Simple

A lot of chocolate-and-peanut-butter desserts ask you to make a filling, chill it, coat it, and chill it again. These do not.

You make one chocolate mixture, spoon it into mini paper cups, drop the peanut butter into the chocolate, and freeze the whole pan until solid. The liquid stevia is optional, so you can taste the chocolate before deciding whether it needs more sweetness.

That is the real advantage of this recipe: chocolate peanut butter flavor without building a filled candy cup.

These Are a Swirl, Not a Peanut Butter Cup

Peanut butter cups and peanut butter fat bombs tend to get filed together, and these are not quite the same thing. The peanut butter goes into the chocolate rather than under a lid of it, which is why the tops come out marbled instead of smooth.

If a proper cup is what you are after — peanut butter filling, chocolate sealed on both sides — that is a different recipe, and we have one: our low carb double-stuffed peanut butter cups. These fat bombs are the simpler, quicker version of that idea.

What Matters Before You Start

• Use unsweetened cocoa powder. A sweetened cocoa mix changes both the flavor and the carb count.
• Stir natural peanut butter before measuring it. Ours is Smucker’s all-natural. Natural peanut butter separates in the jar, so give it a proper stir first. The recipe then warms it briefly so it is loose enough to spoon into the chocolate. For what to look for when you buy a jar, see our guide to whether peanut butter is keto-friendly.
• Coconut oil is what firms up as the mixture chills. We have not tested a different fat here, so we would not treat butter or another oil as a proven one-for-one swap.
• The sweetener is optional. We like the chocolate a little sweeter, but you can taste the whisked mixture before adding it.

Keep Them Chilled

These are a treat you bring out and put back. They soften at room temperature, so keep them in an airtight container in the refrigerator or freezer between servings.

They go well with a warm coffee, or a cold Dalgona coffee if you are making more of an occasion of it.

More Keto Fat Bomb Recipes

If you are here because you want a small no-bake keto treat rather than this specific peanut butter version, we have a few very different directions to go:

• Keto Cookies and Cream Fat Bombs use a creamy protein-powder base with a chocolatey crumb.
• Keto Strawberry Cheesecake Fat Bombs are the fruit-and-cheesecake option.
• Keto Peanut Butter Balls are better if what you really want is a firmer peanut-butter candy dipped in chocolate.

Wrap-Up

I love these because they eat like a truffle — small, cold, and gone in a bite or two. The peanut butter runs through the chocolate rather than sitting in the middle of it, so no two of them come out quite the same.
