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.

How to make keto peanut butter fat bombs
These tasty bites pack a powerful amount of energy! Make them ahead of time and store them in the fridge for a ready-to-go, delicious snack.
You can see how I make these fat bombs in this short video or read the step-by-step instructions below:
Step 1: In a small bowl, mix together the coconut oil, peanut butter, salt, vanilla extract, and liquid stevia (or another no-calorie sweetener). Whisk until smooth and creamy.
Step 2: Line a 6-muffin tray with muffin paper cups. Spoon about 3 tablespoons of the peanut butter mixture into each cup.
Step 3: Place in the refrigerator for at least 1 hour, or overnight, to set.
Step 4: While the peanut butter layer is chilling, whisk together the ganache ingredients until silky smooth.
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.
Now you have delicious chocolate and peanut butter cups to enjoy throughout the week! Be sure to store them in the refrigerator.
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!
Storage
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.

Lovely
I know you said refrigerate for up to a week but can you freeze them? I don’t think I can go through them that fast and I’m the only one who will eat them.
I haven’t tried but I think freezing should work
I made a double recipe because my grandchildren love them!
do you use unrefined or refined coconut oil? what type of coconut oil do you use, and what brand? also, what peanut butter do you recommend? thanks!!
You can use either. Refined coconut oil has a milder scent and flavor, but if you enjoy the coconut flavor I’d choose unrefined
OMG thank you soo much! A couple weeks ago I tried another recipe similar but this was waaaay better: the flavor is more peanut butter than chocolate, it’s sweet and salty, and it’s just the perfect bite size treat. I made mine in mini muffin paper cups and tins. I will check out more of your recipes now. Thank you again!
This recipe is very satisfying for a snack. I have been on tge low carb keto diet for 3 weeks and this is the first snack besides frozen berries that I have had. Easy to make and well worth it.
Love these!! So easy and so good.
I love this recipe. However I tried it with MCT coconut oil but it doesn’t want to turn solid. So far it has been in the freezer for about 5 hours and it has yet to become solid. I don’t know if I would add some butter to it to help with the process or just throw it all way.
MCT will never turn solid, but instead of throwing it away, you could make a keto milkshake, or add it to your coffee, or maybe make some keto mug cake out of it. There’s always a way to use a recipe, even if it doesn’t turn out exactly how you’d planned. 😉
