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:
- Smucker’s Natural Peanut Butter
- Crazy Richards 100% Peanuts
- Spread the Love Naked Organic Peanut Butter
- Kirkland Organic Creamy Peanut Butter (Costco Brand)
- Santa Cruz Organic Peanut Butter
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.

Absolutely delicious. I keep mine in the freezer. I make them all the time.
They’re such a great treat to have available whenever you’re craving something sweet. Glad you love them.
These are by far the most delicious creation! If you like Reese’s Peanut Butter cups, you will love these. The only issue I had with the recipe is that there wasn’t enough chocolate to form a complete layer over the peanut butter, but I swirled it over the top and it worked just as well. Will be making theses weekly for my family!
That is so awesome! Glad you’ll be making these on a regular basis.
Can you sub almond flour for the coconut flour?
You can but would need to sue 4x more almond flour
These are amazing and I use almond flour instead. And yes, 4x more is the key!!
My husband and I enjoy these on an almost weekly basis.
I’m so glad you and your hubby enjoyed these!!
I am so excited to try these. I was unable to find Lily’s chocolate. Are there other chocolate recommendations?
You can click the Lily’s link in the recipe to order it from Amazon. Your local grocery store should carry some type of sugar free chocolate chips that you could use.
Walmart sells lily chips now 🙂
Awesome!
To me, it tastes just like a Reese’s peanut butter cup. This recipe is God sent since Reese’s are my favorite candy that I can’t resist. Thanks so much for sharing!
How many servings are in a batch? Just wondering how many to cut to get the same nutrition listed above. I did nine but seem big…however SO delicious!
The serving size is in the top left-hand side of the recipe card. I’m glad you enjoyed them!
Lily’s is so pricey. Can i use regular 100% cacao no sugar chocolate and just add my own sweetener? I find stevia/swerve too chemical like. I prefer using natural sugar derived from plants like coconut palm which is low glycemic but I don’t know if its low carb/keto. Let me know your thoughts.
I’ve only fixed the recipe as is so I’m not sure about the changes you suggested.
Omg! I want to eat the entire pan! Life saver for sure. I used Lily’s Dark chocolate instead and it was amazing! They are a little runny but I think it’s due to the creamy peanut butter I used. Thank you so much for this recipe!
You’re welcome. I’m glad you enjoyed them.
Best treat I have made, thank you!
You’re welcome. Glad you liked it!
Hi there, In a holiday cookie party dilemma. I would buy the Lily bars on amazon but I am out of time. Can i substitute any other chocolate?
Your local grocery store should have sugar free chocolate chips, which you could substitute. I know Walmart carries them.
Does it have to be monifruit powder sugar.i only have regular monifruit sugar..
You can grind a classic sugar free sweetener into powdered in a blender. That being said, I was out of powdered before and used Monkfruit and it worked fine.
I ABSOLUTELY Love these! It is hard to stay out of it.😅
They really are hard to stay out of!
Has anyone tried using Almond butter? I have a peanut allergy.
I have only fixed it as the recipe says.
Yes and it’s absolutely delicious!!
This is a very forgiving recipe! I’m getting ready to move and don’t have all my bake ware. I also don’t know where my monkfruit is, so I used Splenda. (My highest concern is low carb, not ketosis.) I only had Lily’s chocolate chips, so I added a little Splenda. Then it seemed too think, so I added another tbsp butter to the topping. I spooned the PB mixture into dollops on the paper, then spooned the chocolate part on top. I’m not saying it will look as good as the pictures, but it will taste great! I can hardly wait for the mixture to set up.
I just moved so I understand where you’re coming from! Trust you enjoy them!
Truly, this peanut butter filling taste JUST like the real deal inside a Reese Cup! I have’t been able to replicate that keto or non-keto! I wanted to experience the real deal, so put them in a muffin tray with silicone liners and made 12. Due to the products I used, I ended up getting 1g net carb each for the batch of 12. Santa Cruz peanut butter only has 2g net carbs per 2T and is wonderful (I used crunchy). I also use the Lily’s semi-sweet chips which are 0g net carbs while their bars usually have between 4-12g per 3oz bar, and the dark chocolate chips have 1-3g per 14g… although they have new milk chocolate chips that have the same 2g net carbs as the dark chocolate, so I’ll be trying those next time I make these… and there WILL be MANY next times! Thanks so much for this delicious recipe!!! Reese cups were always a weakness and I haven’t had anything even close in a few years!!!
You’re welcome! Glad you liked the recipe. Nothing like Reese Cups!!
Just made these and they were soooo good!! I used powdered swerve because thats what I had and oh my goodness, so yummy!!! Great, easy recipe! Thanks!!
You’re welcome! I’m glad you enjoyed them.
