    Healthy Peanut Butter Cups (keto)

    Jump to Recipe

    These healthy peanut butter cups are perfect for Reese's fans that want a delicious sugar-free treat. This easy recipe only needs 5 simple ingredients & 15 minutes to make. The combination of creamy sweet peanut butter & layers of chocolate is decadent & divine yet also keto, low-carb, low-sugar, dairy-free, vegan, & gluten-free.

    Best Keto Peanut Butter Cups

    These healthy treats are a great snack or dessert when you crave something sweet. They have no sugar & fewer calories than my recipe for Old-Fashioned Peanut Butter Balls. So indulge without guilt!

    This is a copycat of store brands like Choczero, Justin's, or from Costco, or Trader Joe's which compares to Atkin's or Slimfast. These peanut butter cups are healthier & taste even better. The best part is these are homemade and you can control the ingredients.

    How Many Carbs & Calories

    This recipe results in a version that is high in fat and low in carbs. That is what makes these also a keto-approved fat bomb. Here is a summary of how many calories, fats, carbs, & proteins are in each serving. See the recipe card for complete nutritional information.

    FOR EACH -  185 calories - 17.8 fat - 1.9 net carbs - 3.3 protein

      Ingredients

      Here is all you need to make this recipe. It is important to use sugar-free or low-sugar peanut butter. Cacao powder gives a dark chocolate flavor that is rich & satisfying.

      Best Keto Peanut Butter Cup Ingredients
      • Natural Creamy Peanut Butter
      • Powdered Monk Fruit Erythritol Blend
      • PBFit
      • Coconut Oil
      • Cocoa Powder
      • Flaky Sea Salt - optional
      • Vanilla Extract - optional

      Peanut Allergy? Natural unsweetened almond butter can be used as a substitute.

      I use PBFit in this recipe and no almond flour. This results in the best texture being creamy & not grainy. There is no honey, maple syrup, sugar, milk, or wheat in this recipe which makes it great for anyone with allergies, or dietary & lifestyle choices.

      See the recipe card for amounts & full instructions.

      How to Make Healthy Peanut Butter Cups 

      To make homemade peanut butter cup fat bombs, it only takes 10 minutes to prep & then let them set in the freezer. The hardest part about this simple recipe is making sure you have the right silicone candy mold to make these. 

      Here are the step-by-step instructions for making this recipe. It is a few steps to mix and layer the ingredients. Then the freezer does all the work.

      1. Make the Chocolate Layer
      2. Make the Peanut Butter Layer
      3. Layer & Freeze

      1 - Make the Chocolate Layer

      To make the homemade chocolate, melt the coconut oil in a small mixing bowl that is microwave-safe. Add the cocoa and powdered monk fruit sweetener. Stir or whisk to combine so that it is smooth.

      2 - Make the Peanut Butter Layer

      To make the homemade peanut butter filling, melt the coconut oil in a microwave-safe bowl. Add the peanut butter, PBFit, powdered monk fruit sweetener, a pinch of sea salt, and optional vanilla extract. Stir or whisk to combine so that it is smooth.

      3 - Layer & Freeze

      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.

      Place molds on a solid surface

      To each opening, you will put in the bottom 1 teaspoon 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 teaspoon 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 ½ teaspoon of chocolate on top of the frozen peanut butter. 

      Sprinkle on some optional flaky sea salt at this time. Now place the peanut butter cups in the freezer to set for the final 30 minutes.

      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. They are so pretty & fun.

      Storage

      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 healthy peanut butter cups are SO TASTY, they will not last long in your freezer.

      They can also be stored in the refrigerator for up to 10 days. They will be softer in the refrigerator. Also, it is best not to stack them in a container or they may lose their pretty fluted shape that traditional peanut butter cups have.

      FAQ

      Are these healthy?

      This recipe is healthier than the classic ones you buy at the store. A package of Reese's Peanut Butter Cups has over 200 calories & 22 sugars! This recipe for a mini healthier version has 185 calories & 1.5g of sugars. These may have a high calorie count by volume but they are made with natural ingredients & most are unprocessed.

      Can't I just use chocolate?

      This recipe is created to make a version that is healthy but also keto-approved. By using a combination of cocoa, coconut oil, & monk fruit a smooth chocolatey layer that is low in carbs & high in fats is created. If you wish to substitute in your favorite sugar-free chocolate bar or chips, like ChocZero, go for it.

      Can crunchy peanut butter be used?

      If you like your peanut butter nutty and want the same texture in a peanut butter cup, you can make the substitution. I have not tried it but the ratio of a 1:1 replacement as I have done in other recipes, like my small batch peanut butter cookies, should work.

      Another Fat Bomb Recipe to Love

      If you love these fat bombs and are a cheesecake or lemon fan, I highly recommend my other no-bake recipe for NO-BAKE LEMON CHEESECAKE FAT BOMBS.

      Equipment

      • Silicone Molds

      Ingredients
        

      Chocolate Layers

      • 6 TB coconut oil melted
      • 1 & ½ TB cocoa powder
      • ¼ teaspoon powdered monk fruit sweetener

      Peanut Butter Layer

      • ½ C coconut oil melted
      • ½ C natural creamy peanut butter

      • pinch sea salt
      • 1 teaspoon vanilla extract optional
      Prevent your screen from going dark

      Instructions
       

      • For the chocolate layer: In a bowl combine the melted coconut oil with the cocoa and powdered monk fruit sweetener. Stir or whisk to combine so that it is smooth.
      • To make the homemade peanut butter filling: In a bowl, combine the melted coconut oil with the peanut butter, PBFit, powdered monk fruit sweetener, sea salt, and optional vanilla extract. Stir or whisk to combine so that it is smooth.
      • Place a silicone mold tray with 15 small openings onto a stable solid surface like a cutting board that is the same dimensions. This is important so that transferring the filled tray to the freezer is easy. The tray is "floppy" and hard to move once filled with the liquids.
      • To each opening, you will put in the bottom 1 teaspoon 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 teaspoon of the peanut butter mixture.  Then place in the freezer to set for 15-20 minutes.
      • To each peanut butter layer, you add more chocolate.  This time you will add about ½ teaspoon 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.
      • 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 for up to a month.

          I have not tried it with the regular granulated monk fruit. Since this is not cooked, the sugar may not dissolve & give you a smooth consistency. Let me know if you try it and how it works out.

        Can you suggest a brand of pure monk fruit sweetener and provide the measurement for that? (The ones with Erythritol cause us major digestive issues and we can’t use that).

          July 25, 2023 at 2:14 pm

          Yes you can try splenda or use a pure monk fruit like IT's JUST MONK FRUIT brand which you can get through Amazon. I did not try it in this particular recipe but have with others. The taste is great but the packaging can be tricky. Without any fillers the pure monk fruit is so light and powdery it can just PUFF up and make a mess / a bit of waste if you are not careful opening it. I hope this helped and let me know what you think.

        Wow. I made these and was totally impressed. I substitutes the monk fruit sweetener for stevia liquid sweetener. Which also helped lower the carb count. I missed eating peanut butter cups from the check out lanes in grocery stores. But then are high in carbs and sugar.. this recipe is the perfect replacement. Tyvm Angela.
