When I saw that Crumbl had their Peanut butter cup ft Reese’s cookies I sprinted to get some… I didn’t run I sprinted guys!!
Even since moving to American, the infamous Reese’s peanut butter cup has been my ultimate guilty pleasure, sure it can be a little too sweet but that combination of chocolate and soft peanut butter center is so good to me! That’s why immediately I knew these cookies had to happen.
This is the best Reese’s peanut butter cookie ever!
I made these peanut butter cookies with a similar base to our CRUMBL Peanut Butter and Jelly Cookies but made sure to add a good amount of chopped-up Reese’s peanut butter cups to stay within the theme. This way you get a thick and soft peanut butter cookie with a ton of peanut butter cup bits mixed in there.
The cookies are all finished with a beautiful melty mixture of peanut butter chips and a little oil to thin it out, then topped with more chopped dup peanut butter cups. This cookie is definitely sweeter than my go-to cookies, but hey it’s Reese’s so everything is acceptable in this case!

What is the purpose of the
corn starch in the cookie?
It’s so the corn starch will keep your cookies soft and melt in your mouth!
These are amazing!! I tried the recipe last Sunday, because I was looking for some good recipes to bake & take on vacation with my brother’s family. I had every intention of taking the cookies into work on Monday morning, but I just couldn’t bring myself to give them away! My boyfriend & I ate them all by ourselves.
So glad that you both enjoyed these Heather!
Girl, delicious!! I added chocolate chucks besides reeses and also potato chips and pretzels, also added crunchy peanut butter inside instead of smooth, then also melted chocolate as well as the peanut butter for topping for my own twist!
Oooh I love that! Sounds delish!
Doubled recipe and made tonight! I made them smaller-got about 35 cookies from a double batch. Super good, just mega sweet! Glad I made them smaller-I could barely eat one! Didn’t have resses chips for frosting, so made my own frosting from butterscotch chips, chocolate chips, peanut bitterer and a dash of corn syrup. Turned out good-just when I put the chopped Reeses on, they ended up melting a bit more than desired. Still good though!
This is a great recipe. The only part I modified was the size of the cookie. I made 18 instead of 9.
Smaller cookies are so cute huh! Enjoy!
Honestly, I rarely take the time to write comments on recipes I’ve made, just because of the time it takes, but this recipe, and all the FAQs in the blog post, is awesome! The cookies came out perfectly, and any questions I had were already answered! I made these for my SIL’s birthday and everyone loved them! Thanks for such great recipes.
OMG, thank you for your kind words! I’m glad everyone loved them 🙂
Super yummy! This was my first time making a peanut butter cookie and the bar is now set high. I just made these last night and they’re almost gone!
So glad you enjoyed them Dany!
I could comment on every recipe and say that’s my favorite and I mean it but this one is seriously one of my favorites!
You’re the best boo!
