Best Keto Peanut Butter Cups

These easy no-bake peanut butter cups are the perfect treat for those Reese’s fans that are on a keto or low carb diet.  To make homemade peanut butter cups fat bombs, it is as simple as making the low-carb chocolate layers, a fat-filled peanut butter layer, and freeze.  The fat in these treats is coconut oil so there will be a slight coconut taste but the overwhelming flavor is absolutely peanut butter and chocolate flavor.  These unreal peanut butter cup fat bombs are not only keto and low-carb approved but they are dairy-free, vegan, sugar-free, gluten-free, grain-free, and diabetic-friendly.

For anyone that is a fan of freezing your Reese’s peanut butter cups, (like me!) this is a dream come true.  If you are like me the craving for something sweet comes late at night and these are great peanut butter cup substitutes to keep you in ketosis instead of grabbing a store-bought one like Justin’s or Trader Joe’s and compares to Atkin’s or Slimfast. The best part is these are homemade and you can control the ingredients including the fat to overall calorie ratio.

The hardest part about this simple recipe is making sure you have the silicone molds to make these.  Below is the item that I used for this recipe and these ingredients will make 15 of them based on the size of the molds show below.  If you are in a pinch, you can use an ice cube tray, please note that the nutritional information is only for the amounts listed below so you can still make sure you use the same tsp amounts for each layer and the calories, fats, net carbs, and protein amounts will stay the same.

Homemade Keto Peanut Butter Cups Using Monk Fruit

I prefer monk fruit as my sugar substitute but you can use other kinds like Stevia.  The amounts used are equal to the recipe listed below and are an easy swap. Below are the few ingredients needed to make a great low-carb peanut butter cup. All the ingredients for these fat bombs are vegan and dairy-free, unlike many other recipes. It is important to use unsweetened peanut butter and cocoa in this no-bake peanut butter and chocolate fat bomb.

We like Adam’s Natural Peanut Butter and think it is the best for a keto diet. I choose to use a combination of natural peanut butter and PBFit in these homemade keto peanut butter cups.  The reason why I do this is after trying a few recipes, I liked the texture of this version better but it also is fewer overall calories, fat, and net carbs but also a bit more protein. This is made with regular PGFit, you can also buy a no-sugar version and have even fewer carbs. Compared to all peanut butter, by using a combination with PBFIT, it reduces the calories by 20 calories each – 1.5 less fat – .4 less net carb – adds .25 protein.

Pouring into Silicone Molds to Make the Fat Bombs

IMPORTANT:  Silicone molds are floppy.  It will be hard to move them once they are filled with a liquid. I highly suggest you put them on a stable base like a cutting board before you begin filling them.  Once the molds and layers are ready, it is time to begin filling them up.

To each opening, you will put in the bottom 1 tsp of the chocolate.  Then place in the freezer to set for 15-20 minutes.

After the chocolate is frozen and looks like the photo below, you can begin adding the second layer. To each chocolate layer, now spoon in 2 tsp of the peanut butter mixture.  Then place in the freezer to set for 15-20 minutes.

BONUS:  if you have any leftover peanut butter mix –  it is basically a peanut butter magic shell. Pour it over your favorite low-carb ice cream for an amazing sundae!  Do not throw it out!

To each peanut butter layer, you add more chocolate.  This time you will add about 1/2 tsp of the chocolate on top of the frozen peanut butter.  Then place the peanut butter cups in the freezer to set for a minimum of a final 30 minutes.

Enjoy the Homemade Keto Peanut Butter Cups

After the last 30 minutes of freezing, the best peanut butter cups should be ready to eat and enjoy.  Simply pop them out of the silicone molds and enjoy.  Any that you are not eating right away can be easily stored in a freezer-safe container that is air-tight.  They will last for up to a month but realistically they probably will be gone faster than that. These keto peanut butter cups are SO TASTY, they will not last long in your freezer.
