Best No-Bake Keto Peanut Butter Bars with Chocolate

My hubby loves Reese’s Cups, but obviously, they aren’t keto-friendly. I tried several recipes I found on Pinterest when we first started eating keto several years ago to satisfy our sweet tooth. Unfortunately, they all tasted like peanut butter flavored coconut oil. After a few wasted and disappointing attempts, I gave up.

Since I am a good wife and love my husband, I decided I’d create a recipe for No-Bake Keto Peanut Butter Chocolate Bars that actually tasted like Reese’s Cups. It took a little trial and error, but I finally got the recipe just right, and they turned out amazingly delicious! In fact, after 23 years of marriage, my hubby got down on one knee and proposed to me again after taking a bite.

Can I have peanut butter on keto?

While some avoid peanut butter since peanuts are technically legumes, which can cause inflammation in the body, many enjoy peanuts and peanut butter with no problems. Make sure to look for peanut butter that doesn’t have any added sugar. Peanut butter is naturally lower in carbs and high in fat, but make sure to look for a brand with no added sugar.

What chocolate bars are low carb?

Several brands make low carb chocolate. In this recipe, I used Lily’s milk chocolate candy bars, but you could also substitute Lily’s sugar-free chocolate chips instead. Also, Choc Zero and Lakanto make low carb chocolate bars.

I’ve included step by step pictures below to illustrate how quickly these come together. Make sure to scroll to the bottom of the post for the full recipe and instructions along with nutritional information in the recipe card.

Ingredients for No-Bake Peanut Butter Bars:

Natural Peanut Butter: Look for peanut butter with no added sugars. I prefer crunchy, but if you smooth peanut butter is your jam, it works just as well.

Butter: To add to the flavor of the peanut butter and add an extra layer of creaminess. It also helps bind the rest of the ingredients.

Coconut Flour: The coconut flour gives these bar structure.

Keto-Friendly Powdered Sweetener: Since the peanut butter doesn’t have any added sugars, you’ll need to add a keto-friendly sweetener for taste. It also works together with the butter and coconut flour to bind the ingredients together and add bulk to the peanut butter.

Lily’s Milk Chocolate Bar – The smooth, decadent chocolate topping is made by melting this sugar-free bar.

Step One: To make the creamy peanut butter layer, mix natural peanut butter, coconut flour, and Lakanto Powdered Sweetener. I loved the added texture that crunchy peanut butter added to the No-Bake Keto Peanut Butter Chocolate Bars, but you can use creamy if you prefer.

Tip: You can use almond flour in place of coconut flour. The conversion is 1/4 cup coconut flour is equal to 1 cup of almond flour.

What kind of peanut butter do you use?

As I mentioned previously, my favorite natural peanut butter is Smucker’s Natural. You’ll want to look for a natural peanut butter without any added ingredients such as sugar or palm oil.

A few natural peanut butter options:

Can I use almond butter instead of peanut butter?

Sure, you can easily substitute any nut butter for peanut butter in this recipe. I would caution to make sure that it is a natural nut butter without any added sugar.

Step Two: I would suggest using a hand mixer to make sure the peanut butter filling is smooth and creamy.

Step 3: Spread the peanut butter layer in the baking dish then pop it in the freezer for 10 minutes so that the layer hardens to make it easier to spread the chocolate layer.

Tip: Line the baking pan with parchment paper to make clean up a snap.

Step 4: I melted a Lily’s Creamy Milk Chocolate Bar sweetened with Stevia for the chocolate layer instead of the dark chocolate Lily’s Chocolate Chips so that it would taste more like a Reese’s Cup. Then, I spread the chocolate layer on top of the peanut butter and put it back in the freezer to set up.

How to melt chocolate so that it doesn’t harden?

The key to melting chocolate in the microwave is to use a low setting so that it melts slowly. This post for methods and tips for how to melt chocolate includes detailed instructions and other methods of melting chocolate.

Can I make keto peanut butter cups with this recipe?

Sure! Instead of making Keto Peanut Butter Cups, which would take a bit more time, I made bars because they are so much easier. But, if you prefer to make cups, spoon a bit of the peanut butter layer in greased muffin tins, pop in the freezer, then melt chocolate for the top layer.

Ingredients

For the Chocolate Topping:

Instructions

  • In a bowl, beat softened butter at high speed. 
  • Add powdered Monkfruit powdered, peanut butter, and coconut flour then beat with a mixer again on medium until all of the ingredients are thoroughly combined. 
  • Line a 9 X 9-inch baking pan with parchment paper (or grease pan) and spread the peanut butter layer evenly then place in the freezer for 10 minutes.
  • Meanwhile, tear the Lily's Smooth Creamy Chocolate Bar into pieces in a small greased glass container and add 1 tablespoon of butter. 
  • Microwave for 30 seconds on the low power setting then stir. If it is not completely melted microwave in 15-second intervals on low power stirring between each until it is melted. Make sure to always stir between intervals as it will continue to melt when you stir it.
    **Do not overcook, or the chocolate will become hard and will not spread. 
  • Remove the baking pan from the freezer and spread the pour the chocolate layer on top of the peanut butter layer, then using a spatula spread it evenly.
  • Return to the freezer for several hours or overnight to allow the No-Bake Keto Peanut Butter Bars to setup. Once they have set up, you can store either in the freezer or the fridge. We tried ours both ways, and they are delicious!

Notes

The sugar alcohols in both the Monkfruit and Lily's Chocolate bar are not included in the nutritional information since most subtract to calculate net carbs. 
You can use almond flour in place of coconut flour. The conversion is 1/4 cup coconut flour is equal to 1 cup of almond flour.
Swerve Confectioners can be subbed for Lakanto Monkfruit powered at the same measurement.

  1. Can you tell me what the full carbs per piece is?? I’m counting all carbs and would love to try recipe.
    Thank you

    These are by far the best!! We make them all the time. Even my hubs that does not like PB is in love with these! Question: Do I subtract the fiber from the carbs for a net carb rating? Thanks!

    1. These are one of my favorites, too!! Yes, you would subtract the fiber to get your net carbs.

    My husband loves these bars. he’s keto committed but needs his treats. We have each lost 20# and are keeping it off. Love your recipes Kasey.

    1. I buy Lakanto Classic and process in the food processor to make powdered, as needed.

  4. Is there anything I can substitute for powdered monk fruit? I am having trouble finding it in the stores.

    1. You could use Swerve Confectioners. If you click on Powdered Monkfruit in the recipe card, it will take you to Amazon where it can be purchased.

    2. I used swerve regular sugar substitute it left a crunchy texture to the bars but tastes good maybe if anything too sweet!

    3. Yes, regular swerve will leave a crunchy texture. You can pop it in a blender and it will become powdered and the outcome will be much better. If they are too sweet, you can easily adjust the amount of sweetener according to your taste. It varies for everyone.

    Hi,
    Loved this recipe, but I made a couple of modifications, I use the 7oz. bag of Lilly’s milk chocolate chips, I melt half the bag and spread in a well buttered 8×8 pyrex dish and also coat the sides, I put that in the freezer while I make the peanut butter, by that time, its frozen, And then I spread the peanut butter on that chocolate, then freeze for about 15 minutes, Then I melt the other half of the bag and put it on the peanut butter, Freeze for a couple of hours before you can gnaw on it. let it freeze overnight and it’ll break up out of the dish like peanut brittle.Put it in a bag in the freezer and you have something there to kill the sweet tooth. It’s so good, you feel guilty.

    1. I would imagine that almond butter woukd be a more “keto” substitute for the peanut butter. ( I haven’t checked..macros may be different) Am I correct?

  8. 5 stars
    We love these so much I make 4 batches at a time for the freezer. Sometimes I add 1/2 cup of roasted peanuts to them!

    1. It’s so great to have these in the freezer for whenever you have a sweet tooth!

    1. I’ve only made them with natural peanut butter, but I would think almond butter would work just fine.
