Peanut butter cup cookies were one of the first keto recipes I ever blogged. Way back in the day, fall of 2015, I tried to take a simple three-ingredient peanut butter cookie and combined it with skinny chocolate (cocoa powder plus coconut oil and sweetener) for a five-ingredient cookie. They were pretty good but now that I'm past the hobby blog stage I wanted to redo that recipe.
I spent some time tweaking the cookie cup part and upgraded the skinny chocolate to a ganache. Topping with roasted salted peanuts sealed the deal. Now, these are great.
I don't know if it's just me but anytime my kitchen is clean I just *have* to bake something. I have a big island that my husband and I made a few years ago out of a hand-me-down dresser and a butcher block top. It was one of the best things we have ever done. We were hesitant to get rid of the kitchen table but as our family grew we just couldn't fit there anymore for dinner.
Once we decided to eat in the dining room and get an island my working space in the kitchen tripled. Instead of 4 tiny squares that make up my kitchen counters and a kitchen table surrounded by chairs I had a big island that is the perfect height for my baking pleasures. It was around the time we made the island that I started blogging. It was meant to be.
Ingredients Needed
Cookie Ingredients:
2 large eggs
½ cup coconut oil
½ cup peanut butter
1 teaspoon vanilla
⅓ cup peanut flour
¾ cup Joy Filled Eats Sweetener
1 teaspoon salt
½ cup almond flour
¼ cup coconut flour
1 teaspoon aluminum-free baking powder
Topping Ingredients:
3 oz sugar free chocolate chips or chopped chocolate
2 oz heavy cream
¼ cup peanuts (roasted salted)
Alternative: Instead of make a homemade ganache you can use homemade or store-bought keto peanut cups (such as these ChocZero peanut butter cups).
How to Make Keto Peanut Butter Cup Cookies
These are very easy to make! I promise. The batter for these low carb peanut butter cookies is very similar to a brownie batter. I set off to make peanut butter blondies by adapting Hannah's Fabulous Brownie recipe and ended up making these peanut butter cookie cups instead.
By swapping out the cocoa powder and part of the liquids for peanut butter you have a moist and tender gluten free peanut butter cookie.
Step One: Mix together the cookie ingredients.
Step Two: Scoop the batter into a mini muffin tin. Bake. When the cookies are done make a little well in the center and fill with ganache. Top with peanuts.
Expert Tip: To make things easier I do recommend using liners in your mini muffin tin. These pop out fairly easily when chilled but go ahead and save yourself the trouble of washing the muffin pan. Next time I make them I will be doing that.
How to Store Keto Chocolate Peanut Butter Cookies
I typically do store all of my low carb recipes for desserts in the fridge. These peanut butter chocolate cookies are fine for a few days at room temperature but for a longer storage move them into the refrigerator.
They can be frozen for 3-4 months. Just wrap them tightly.
Can I Use Another Nut?
If you can't have peanuts in your house I'm sure another nut butter would work just as well. I have some pecan butter I want to try in this recipe. I think they would be fabulous with a few toasted pecans on top and a pecan cookie base.

Megan says
Can’t wait to try these! Can I use melted butter instead of coconut oil?
And if I have Lilly’s semisweet chocolate chips for the ganache, do you think that will be sweet enough or should I add a little bit of extra swerve powdered sweetener?
Taryn says
I think ganache made with Lily's is sweet enough. But if you prefer sweeter chocolate adding a little sweetener is a good idea. If it thickens too much also add a little coconut oil.
Kathy Clinton says
What can you use instead of peanut flour? PB2? Or a different nut flour?
Taryn says
Yes, pb2 will work but it does have added sugar so its not my first choice.
Carol Taylor says
how many cookies in a serving...just one or is that 2 cookies?
Taryn says
One cookie.
Amanda says
Can you sub out the coconut oil for say avocado oil, or do you need the coconut oil to firm them up after?
Taryn says
You need coconut oil. I also don't know how avocado oil would taste.
Crickett says
I haven't tried these yet but they look delicious! I wanted to mention that Target (in the baking section) sells these incredible parchment paper muffin cups that go into the muffin pan. They are about $2.00 for a pkg. of 60, and literally fall off the low carb muffins without even peeling them. Best new kitchen thing I have tried since my air fryer!
Donna says
I want a bigger work space in my kitchen. Can you take a picture of the dresser with the butcher block top?? I would really like to copy your idea, but not sure what to do.
Love your blog and recipes...
Thanks,
Donna
Taryn says
We actually moved and left that in the old house. I miss it!
Karen says
These look wonderful! I am wondering if there is a difference between the peanut butter flour listed in the ingredients and the peanut butter powder mentioned in the instructions. Thank you for sharing!
Taryn says
Nope, they are the same thing. Just look for one without added sugar.
Sharon Anderson says
I am very excited to try this recipe. It looks so delicious and my hubby loves peanut butter cups!
I recently ordered your cookbook "Joy of the Morning " and love that you have included beautiful pictures of the food featured in the recipes! Have you published additional recipe books? I would love to order them! Even though I am all over Pinterest, I love holding a recipe book in my hands!
Taryn says
Thank you Sharon! That is my first cookbook. I'll have a dessert book coming in a couple months 😀
Karennera says
Is the coconut oil measured after melting?
Taryn says
Yes, I pack my measuring cup and the amount before and after melting is very close.
Rachel says
Can I use another sweetener? I have swerve, monk fruit and vanilla stevia liquid.
Taryn says
Swerve or a monkfruit blend like lakanto should work. Use 1.5 times the amount because they aren't as sweet as the blend I use.
Susan says
Can i use baking blend instead of the coconut flour and almond flour?
Taryn says
Baking blend should work. Use a little bit less as it can be drier.
Kathy Pursell says
Could I use THM Baking Blend instead of the coconut & almond flours?
Taryn says
Yes, I think so. I would use a little less.
Ida says
I really want to make these but I don’t have peanut flour on hand. Can I just use extra almond flour?? Thanks!!
Taryn says
Yes, that should work.
Sheryl says
I used peanut butter powder and these taste amazing!
Vicki says
What is considered a serving? One mini cookie cup?
Taryn says
Yes, the nutrition facts are calculated for one cookie. But I think 2 or 3 is still a reasonable amount. Who ever just eats one cookie? Not me.
😉
VICKI says
My husband and I just had 2 each because they are divine!!!!! Best thing we have had on this low carb diet! Thank you!!!
Aimee Morris says
I tried this recipe. The pb cookie portion was delicious, however the ganache needed some type of sweetener. It was very bitter. I will try again and include some on plan sweetener in the ganache.
Thank you!
Taryn says
Did you use a sugar-free chocolate chip like Lily's? You could also use a sugar-free milk chocolate if you prefer that. With a lighter chocolate you shouldn't need additional sweetener.

This recipe hit my mailbox this morning and I thought, "Great! This is just what I need for the small group meeting tonight." I went to the store to get the few things I didn't have and set to work. I got 32 mini-muffins. Other than that, I ran into problems. I baked them for 15 minutes. The recipe says to make a well for the ganache. Well, I have firm little muffins that break apart when I try to make the depression. Was I supposed to do that BEFORE I baked. I admit that I used an electric oven (which I hate, but it's not my house). I could have taken them out at the 9 min 25 sec mark and they would have been lightly golden with a squishy center. The only way I can think to salvage this situation is to make the ganache and spoon it over the top of the muffins. Any suggestions from your end?
Taryn says
Are you trying to make the well after removing them from the pan? You need to make the well first. After baking but before removing them. I will edit this to make that clearer. You can definitely just use the ganache as an icing.
Connie Condra says
Tried both ways. They were too firm and just cracked. I did pour the ganache over the top and added some crushed peanuts. Everyone in our small group thought them quite tasty. One member who cannot eat baked goods made with white flour was ecstatic and wants the recipe. If I had taken them out at the 9 min 25 sec mark, I could have gotten a nice indentation. The reason I didn't was because of the eggs. Also, I moved to Arizona about 9 months ago and am still adjusting to how to cook out here. Things seem to act differently.
Patty in Co says
Hi Taryn.. Love your recipes, but for some reason since you switched over your blog to the new format, I have a heck of a time getting them to save on Pinterest. I couldn't get this one to save at all. Don't know if it's me or if everyone is having the problem. Not a big deal because I follow you on Pinterest, but I have to go into your Pinterest page and search all your recipes till I find the one I want. You do such a great job with your recipes and I LOVE THEM!
Taryn says
Oh no! Do you still see the gray bar with the Pinterest icon? It should be at the top and bottom of the post.
