These Keto Peanut Butter Fat Bombs only use 5 simple ingredients and couldn’t be easier to make! Creamy peanut butter topped with chocolate ganache makes the perfect decadent snack.
If you’ve never tried fat bombs before, they are… well… the bomb!
Not only are they super easy to make, but their low-carb, high-fat content is also great for avoiding a blood sugar spike.
Keto fat bombs are made from a high-fat base such as nut butter, coconut oil, avocados, or cream cheese. Then, you add tasty low-carb goodies to go with the flavor. This is usually ingredients like sugar-free chocolate for a sweet fat bomb or bacon for a savory fat bomb.
The high-fat base in this recipe is made from a combination of peanut butter and coconut oil for a rich, creamy texture. Topped with a bit of chocolate ganache, it becomes a decadent treat that’s perfect for an on-the-go snack or when you need to satisfy your sweet tooth!
These peanut butter and chocolate fat bombs make snacking on a low carb or keto diet easy and stress-free.

Step 5: Spoon about 1 tablespoon of chocolate ganache on top of each fat bomb.
Step 6: Chill in the refrigerator at least 30 minutes before serving.

Other nut butters and flavors
Chocolate and peanut butter is a classic combination. However, there are plenty of ways to make this recipe all your own if you want to shake things up!
If you don’t prefer to use peanut butter or have an allergy, you can substitute with any other smooth nut butter. Just be sure to use a brand that has no added salt or sugar. This is a great way to experiment with different tastes.
Another way to get creative with the flavor of these fat bombs is to use an edible essential oil. A flavor like peppermint or orange is simply amazing with the chocolate ganache. Use 1 – 2 drops of the flavored oil to give your fat bombs a unique spin!
For even more ways to mix things up, you could use protein powder in the peanut butter mixture to add flavor and protein. Or try adding some chopped nuts for more texture!
There are plenty of ways to play around with this recipe and make it your own.
Size and shape of the fat bombs
Because we make these fat bombs in a 6-muffin tray, they are BIG! We consider each one to be 2 servings.
If you have a smaller muffin tray with 9 or 12 cups, you can easily make smaller fat bombs that are closer to 1 serving each. Or, if you have a mini 24-muffin tray, you could make mini fat bombs!
I like using muffin cups because the shape of the fat bomb reminds me of a traditional peanut butter cup. However, if you have chocolate molds, you can really get creative with how you want these to look. Feel free to have some fun with the shape!
Do you have to be keto to enjoy these?
Fat bombs are great for anyone following the high-fat, low-carb ketogenic diet.
However, that doesn’t mean that these are off-limits to everyone else! As long as you factor them in to your macros for the day, you can certainly enjoy them in moderation.
They will be much healthier than traditional peanut butter cups, and the fat content will give you a great burst of energy without spiking your blood sugar!
Because these fat bombs are made with mainly coconut oil and peanut butter, they need to be stored in the refrigerator. If you leave them out at room temperature for too long, you’ll end up with a puddle of peanut butter and coconut oil. It will be a tasty puddle, but quite messy to eat!
Instead, keep these in the refrigerator and just grab one when you’re ready to enjoy.
I recommend storing them in an airtight container in the refrigerator for up to a week.
