Peanut Butter Cup Fat Bombs are the perfect keto & low-carb snack to keep you going when you just need a little something before your next meal.

Table of Contents
Ingredients You’ll Need
- Coconut Oil: Coconut oil contains a high amount of saturated fat, but it consists primarily of medium-chain triglycerides (MCTs).
- Salted Butter: I like to use KerryGold salted butter for this recipe because I find it makes a smoother fat bomb.
- Peanut Butter: You can use either creamy or crunchy for this recipe, but definitely make sure it’s sugar-free.
- Dutch-process Cocoa Powder: Also known as alkalized cocoa powder, Dutch Process Cocoa Powder has lower acidity, smooth flavor, improved solubility, and a richer color.
- Xylitol Sweetener: If you’re on a low-carb or keto diet, xylitol or other sugar substitutes will be your best friend. Xylitol looks and tastes like can sugar and is measured 1:1.
- Sea Salt: Sea salt adds the little bit saltiness but you can omit since you’re using salted butter if you’d prefer.
How to Make Peanut Butter Cup Fat Bombs
Add all ingredients to a heat proof measuring cup and microwave for 40 seconds. Pour into a freezer-safe tray and chill for 1-2 hours. Remove and store in a zip top bag in the refrigerator for up to 1 week.
Tips & Storage
- Use a silicone ice tray if you want to remove them easily after freezing. This is the one I use which serves multiple purposes like freezing fresh herbs, or extra tomato paste.
- Keep in the fridge for 1 week. Store in a zip top bag or an airtight container. You can keep them frozen up to 3 months, but you’ll need to defrost for 20 minutes before you can eat them.
I don’t know about you, but about 2 PM my brain starts giving me queues that it’s time to make the rounds and beg people for any type of sugary something they may have at their desks. It’s not a good look. These Peanut Butter Cup Fat Bombs are the perfect thing to bring to work, store in the fridge for when those cravings start hitting.
