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.

What other chocolate bar can i use i don’t really look forward to spending 25$ for 4 candy bars
Lily’s is the only one I have tested in this recipe. Lakanto makes a sugar-free candy bar. You may also want to check at your local grocery store for options.
Could you use powered peanut butter with this?
I’m not sure. I’ve only made it as so, so I’m not sure how it would turn out.
I’ve used powdered peanut butter and even added chia seeds in with it too and it worked great! Obviously you reconstitute the powder first.
I just want to say that if your chocolate seizes from over heating, you can add a little coconut oil to it to get it back.
Is the butter unsalted or salted?
I have always used whatever I have on hand, which is usually salted. If you are particularly sensitive to salt I’d use unsalted.
Just to add to all the other accolades – these are absolutely delicious!
I used Swerve confectioners and I had 4.5 oz of Lily’s dark chocolate chips (left from eating out of the bag), so I used that and it was just the right amount.
I’m not Keto, but I don’t eat sugar or white carbs and I count calories. These bars are very filling – 1/16 is really a generous size. Thank you!
Fantastic!I’m glad you enjoyed them.
This “dessert” is by far the best “keto”, low carb dessert I have made; and I have made a lot. The texture and sweetness is on point in the peanut butter part. It even got the approval of my non-keto family. Thank you so much!
That is so glad to hear that you all enjoyed it! You are very welcome.
Always love Kasey’s recipes. This one does not disappoint.
Thanks so much, Kim!
Fantastic and easy to make.
So glad you enjoyed it!
I have made these many, many, times! They are delicious!
Fantastic! Thanks for taking the time to comment and leave a rating.
A great treat! I used almond butter and a silicone baking tray with 24 sections to make them bite size!
Awesome! Glad you enjoyed it.
Just want to say I appreciate all you do Kasey.. I’ve followed you for awhile now and have read your keto family stories. You’re the bomb Kasey and I’m just sending a big darn Thank You. All Your Recipes Are Thee Best!..
Thank you so very much. I appreciate you taking the time to write such a kind and encouraging comment.
These are absolutely delicious and so easy to make!
I’m so glad you loved them!
I love this recipe! I have made it several times and it’s only flaw is that it tastes so delicious that I find it difficult not to eat loads in one day.
Haha! So glad you loved it.
Hands down best keto recipe to date! I only did 1/3 C sugar as I don’t like my sweets too sweet. And I only had Lily’s milk chocolate chips on hand so I melted those instead of the bar…perfection! Thank you for a great recipe!
Perfect! Sounds delish. So glad you enjoyed it.
Can you substitute olive oil for the butter?
Hmnmmmmmm…I’m not sure. I’ve only made them as is. I would hesitate to use olive oil personally.
