It all starts with getting your oven warmed up. I know it’s sometimes hard to wait for an oven to preheat because you just want those cookies now.

But allow it to get to 350 degrees first so your cookies will bake evenly and gather your ingredients.

Dry ingredients in a small bowl for Crumbl cookies

Grab a small bowl and add all the dry ingredients. That’s the flour, baking soda, and salt. Mix it together and set it aside.

Grab another bowl, or stand mixer if you have one. This one will be used for combining the butter, peanut butter, and both the brown and white sugars.

Grab the paddle attachment and let your mixer beat this all together for you until you get a nice, smooth texture.

If you don’t have a stand mixer, use a large bowl and a hand mixer.

When the mixture is smooth, add the egg and vanilla extract and continue beating it together until combined.

And now, the fun ingredients! You’ll stir in your chopped Reese’s Peanut Butter Cups. 

Five large pieces of cookie dough on a cookie sheet. The cookies are round.

When the cookie dough is ready, you are going to separate it until you have eight uniform pieces. You will roll each of these eight pieces into cookie dough balls, and then you’re going to put them on your cookie sheet.

Flatten the cookies until they are about 1/2 inch thick.

Bake cookies for about 12 minutes.

Tips For Baking

  • First, use parchment paper. Parchment paper is great for helping the cookies bake more evenly, and they won’t stick to the cookie sheet when you take them off with a spatula.
  • The second tip is to use two standard-sized cookie sheets. This recipe yields eight really big cookies, and they need room to spread out. If you split them up, so you have four on one sheet and four on another, that should give them plenty of room to spread a little bit while they bake.
  • Once you’ve got them arranged on your cookie sheets, flatten them so they’re roughly 1/2 an inch in thickness. Then you can pop them in the oven…about 12 minutes should do it.

What you’re looking for here is edges that are nice and set while the centers look soft. One crucial thing to note here is that while they should look soft in the middle, they should not look wet.

When they’re ready, take them out of the oven and let them cool.

Yes, I know you’ll want to eat them at this point (I know I did), but they aren’t quite done yet.

As they cool, go ahead and melt the peanut butter baking chips along with some butter.

You can do this with a double boiler, but if you don’t have one or you just want to speed things along, you can do it in a microwave-safe bowl. Set the microwave timer for 15 seconds at a time to prevent burning them.

Once they’ve melted, stir them until they have a nice and smooth texture.

You’ll then spread a spoonful of that melted peanut butter deliciousness on the top of each golden brown cookie.

Finish it off with more chopped-up peanut butter cups, doing so quickly before that melted peanut butter chip mixture sets.

Optional Ingredients

If you want to add a little variety to your cookies, here are a few ingredients you can add at different times.

  • Natural peanut butter instead of the peanut butter chips on top of the cookie. Peanut butter drizzle is always a good thing.
  • A sprinkle of flaky sea salt on top to add a little flavor variety.
  • A small sprinkling of ground cinnamon and brown sugar on top for a warm brown sugar cinnamon delight.
  • Milk chocolate chips in the batter for even more chocolate.
  • Dark brown sugar instead of light for a deeper flavor.

How to Store Crumbl Copycat Peanut Butter Cup Cookies

Tempting as it is to gobble all eight chewy cookies down yourself, they’re filling.

To store them, put them in either an airtight container or a Ziplock bag. You can keep them at room temperature for up to three days, but I bet they won’t even be there for 24 hours!

Notes

Tips For Baking The Cookies

  • For best results, use parchment paper.
  • Use two standard-sized cookie sheets. This recipe yields eight really big cookies, and they need room to spread out. Split them up so you have four on one sheet and four on another. That should give them plenty of room.
  • Once you’ve got them arranged on your cookie sheets, flatten them so they’re roughly 1/2 an inch in thickness. Then you can pop them in the oven…about 12 minutes should do it.

Be sure to use a microwave-safe bowl if you microwave the peanut butter chips.

Can you make ahead and freeze?

Hi Dawn,

You can! I would probably freeze them without the frosting so it won't get crumbly.
