Keto Peanut Butter Chocolate Fat Bombs are probably the best snacks ever invented, if you ask me. Trying to stick to low-carb eating but keep getting whacked with chocolate cravings? Same.
Trust me, these little fat bombs have saved my bacon more than once (ok, more like weekly). And hey, if you’re after more inventive keto goodies, you might want to check out this wild keto peanut butter earthquake cake.

It’s on another level. But first, let’s talk all things chocolate, peanut butter, and keeping it simple.
What Are Fat Bombs?
Bet you’ve heard that phrase kicking around—fat bombs. It sounds dramatic, but honestly, it’s just a fun way of saying “snack that’s mostly healthy fat, with barely any sugar.” Perfect for people on keto, or honestly any low-carb plan. You want your hunger handled and your cravings to simmer down? These are your ticket.
They usually mix healthy fats (think coconut oil, peanut butter, or cream cheese) along with a little flavor boost—like cocoa powder or sometimes even actual chocolate chips. Thing is, I first made these for a road trip because gas station snacks are basically sadness in a bag if you’re off sugar.
They’re not “energy balls” either, which, you know, are always mushed up dates and oats. Not today.
I doubted fat bombs would taste good the first time. But…they’re a total winner. Like a healthy Reese’s. I keep coming back for more.

Ingredients for Keto Fat Bombs
Making Keto Peanut Butter Chocolate Fat Bombs means you mostly just need pantry basics. Here’s what you want:
- Creamy peanut butter (natural, no added sugar)
- Coconut oil or butter (I go with coconut oil for flavor)
- Cocoa powder (unsweetened for best keto results)
- Powdered sweetener (erythritol or stevia, whatever you handle best)
- Pinch of salt (it’s so important—don’t skip!)
- Vanilla extract (this really makes it pop, trust me)
A little note: Sometimes I toss in chia seeds or a pinch of cinnamon, but that’s only if I’m feeling extra snazzy.

How to Make Chocolate Peanut Butter Fat Bombs
Okay, now for the get-to-the-point instructions. The best thing about these is you do not need to know fancy kitchen stuff. You can do this half-asleep (I have).
Start by melting your coconut oil. I nuke it in a bowl in the microwave for a minute. Done.
Stir in your peanut butter, cocoa powder, and sweetener—just swirl everything together until it’s smooth and thick-ish. Lick the spoon, it’s allowed.
Add a splash of vanilla, and that pinch of salt. Tastes like dessert already, no kidding.
Spoon the mix into silicone molds or mini paper muffin cups. Put them in the freezer about 20ish minutes, and honestly? You’re in business.
Pro tip: If you accidentally taste the mix before it’s set and eat half of it, absolutely no judgment.

What Type of Peanut Butter Should I Use?
Hands down, the right peanut butter is crucial, and not to be dramatic, but some jars are just sugar bombs in disguise. Find peanut butter where the ingredients are basically two things: peanuts and salt. That’s it.
I once tried using “regular” peanut butter by accident—big mistake, blew my carb count for the day. The natural stuff keeps the fat up and sugar way down, which is exactly what you want for Keto Peanut Butter Chocolate Fat Bombs.
Crunchy is fine, but creamy blends better (learned this the messy way). Be wary if you’re shopping the discount aisle. Sometimes the “lite” is not what you think—extra sugar, extra weird stuff. Yikes.

Tips for Making the Best Fat Bombs
Alright, some hot takes after probably too many kitchen sessions:
- Use silicone molds for easy popping out. Paper liners make your life less sticky, but molds? Life upgrade.
- Don’t skip the salt! Brings out the chocolate flavor like you would not believe.
- Store in the freezer if your house gets hot, unless you like goo. Fridge works if you want them on the softer side.
If you want to get fancy, sprinkle chopped peanuts on top before freezing. Or go wild with a pinch of sea salt flakes. Point is, you do you.
