Peanut Butter Fat Bombs are no-bake chocolate peanut butter fat bombs, an easy keto sweet snack with only 1.4 grams of net carbs.

Is peanut butter keto?

Not all peanut butter brands are keto-friendly. You should always check the ingredients list of the peanut butter you buy and look for: no added sugar, no added vegetable oil. Pure keto peanut butter is made of one or two ingredients: peanut butter and salt, that is all.

Peanut butter fat bomb – Keto sweet craving fix!

I am a sweet tooth, and I am passionate for peanut butter. That’s actually a good thing when you eat low carb as peanut butter does not contain many carbs and is full of healthy fats.

These peanut butter fat bombs or keto Reese peanut butter cups are my favorite snack with my almond joy bounty bars. If I crave sweet, that is what I grab in the fridge.

The good thing about those peanut butter fat bombs is that you can make them in less than 20 minutes with only 5 ingredients that all keto lovers have in their pantry.

Peanut butter fat bombs keto vegan All you need is :

  • Peanut butter  – make sure you use unsalted no sugar added peanut butter made with 100% peanut.
  • Coconut oil – if you don’t like the coconut flavor of coconut oil, use refined coconut oil.
  • Cocoa butter or butter – both options are tasty. My husband is vegan, and I like to share my treats with him, so I usually prefer to use cocoa butter. Plus, cocoa butter really adds a real chocolate flavor to those little treats. It is like eating real chocolate without the sugar!
  • Powdered sugar-free sweetener – I am using powdered erythritol because it dissolves better than crystal erythritol, but if you don’t mind having some crunchy bites of sweetener, you can use your regular sugar-free crystal sweetener.
  • Stevia drops – I love to add some vanilla creme-flavored stevia drops. It is optional, but this adds an extra boost of sweetener and a delicious vanilla cream flavor that I love. Feel free to use the stevia drops you like, of course.

Chocolate shells – keto Reese peanut butter cup

You don’t have to add a chocolate shell on those peanut butter fat bombs. They are absolutely delicious as is.

But, if you miss a good Reese peanut butter cup, adding my chocolate shell recipe will make you a real treat.

I love to use chocolate silicone molds that are small but high to create thick peanut butter fat bombs. If you don’t have such molds, you can use a regular ice cube tray.

Make sure you spray oil into your tray to make it easier to release.

Eat cold or frozen

What I love the most about those treats is that you can store them for up to 3 months in the freezer and they taste amazing frozen too!

I know it sounds crazy, but some days I store mine in the freezer, and I crave sweets so much that I can’t wait 20 minutes to get them softer.

They taste like little ice cream cups. Delicious! Otherwise, it defrosts really fast as well.

Feel free to double the batch, and you are good for few months of treats.

It is a very good way to indulge in a sweet treat without blowing your carb count or reach something you shouldn’t eat.

Storage – fridge or freezer

I would recommend storing those peanut butter cups in your fridge, especially in summer, or they get very soft and will melt quickly above 30C.

If you don’t want to eat them too cold, simply wait 20 minutes after you remove them from the fridge.

  • In a small microwave-safe glass bowl, add all the ingredients: peanut butter, coconut oil, butter (or melted cocoa butter).
  • Microwave in 30-second bursts, stir and microwave again until the coconut oil and butter are fully melted. Make sure you stir between each 30-second burst to not 'burn' the peanut butter. You can also do this on the stove, in a saucepan, under medium heat.
  • You should obtain a consistent batter, very runny, almost like water. Next, stir in the powdered sugar-free sweetener and vanilla creme flavored stevia drops if used. The batter will thicken slightly but still be very runny, and that is what you want. Taste and adjust sweetness with more stevia drops at this point if needed.
  • Place each chocolate silicone mold on a plate (this makes it easier to carry them to the freezer when filled). Fill each hole of the silicone mold with the peanut butter mixture up to the top. 
  • Place your plate with the filled silicone mold in the freezer for 20 minutes or until the chocolate has firmed up.

Chocolate shell

  • Meanwhile, prepare the chocolate shell of your peanut butter fat bombs.
  • In a small glass bowl, add the sugar-free chocolate chips, coconut oil, and a pinch of salt if you like. 
  • Microwave in 30-second bursts, stir and repeat until the chocolate is melted.
  • Cover a plate with parchment paper, lightly oil it with oil spray. Set aside. 
  • Remove the peanut butter fat bombs from the freezer. Carefully unmold each fat bomb by pushing them out of the silicone mold. 
  • Use 2 forks to dip each fat bomb into the melted chocolate, and place them on the plate you prepared to cool down. Repeat until all the fat bomb has been covered with chocolate.
  • Bring the plate in the freezer again for 10 minutes to set the chocolate shell. 
  • Remove from the freezer and enjoy straight away! 

Storage Options

  • You can store your peanut butter fat bombs in an airtight container in the fridge for up to 3 weeks (if made with cocoa butter) or up to 1 week if made with butter. I found that the taste changes slightly if I use butter and store them for longer. 
  • Another option is to freeze them in ziplock bags for up to for 3 months. 
  • Eat them cold from the fridge or frozen! Don't store at room temperature or they will soften too much! 
I use cocoa butter for a dairy free fat bomb, however you can use butter if preferred.

  1. Do you realize the link you provided for Cocoa Butter says it “should not be ingested” in the product description?

    • Sorry for the issue on this link it has been updated. I am using edible cocoa butter from nuvia, you can find it here. This is eible cocoa butter for any DIY recipes. Enjoy, XOXO Carine.

  2. Can these be made with almond butter and maple syrup or honey? I dont use stevia or any sweetener other than dates, honey or maple sugar. THANK YOU!
