Reese’s Brownie Cookies

Brownie Cookies have become really popular in my household, and lately I’ve wanted to try something a little different. I’m adding two delicious Reese’s candies — the mini cups with their gooey, peanut butter center plus crunchy Reese’s Pieces for double the texture. The result? Unbelievably delicious, melty, ooey gooey Reeses cup cookies!

Brownie Cookies

Haven’t you ever wanted to enjoy all of your favorite desserts all in one? Well, I sure have! That’s why I can’t get enough of brownie cookies. 

Using a simple brownie mix and your usual cookie ingredients, you have a treat that has all of the flavor and texture of brownies in one fudgy, chewy, easy-to-eat cookie!

These Reeses cookies are just the start! You can enjoy these iconic chocolate and peanut butter candies in cakes, pies, fudge, and even cocktails!

Ingredient Notes & Substitutions

  • Brownie Mix – My absolute favorite is the Betty Crocker mix! It comes in an 18.3-ounce box.

    Other brands will work, of course, as long as it comes in the same amount.
  • Chocolate Syrup – Definitely a must-have ingredient for moist, chewy, chocolatey sweets!

    Chocolate sauce works but is much richer — and these Reeses cup cookies are already pretty rich!
  • Reese’s Baking Cups – The mini cups are a suitable substitute too. 
  • Reese’s Pieces – These add an absolutely wonderful texture to the otherwise totally chewy, soft Reeses cup cookies.
  • Peanut Butter Chips – We need a little more peanut to balance the cocoa! For some substitutes, check out the tips below.

Tricks for Making Ridiculously Tasty Reeses Cup Cookies

  • Undercook the batter for super soft, chewy Reeses cookies!

I’ve really emphasized that my brownie cookies are really, really soft… and they are!

But my trick to making them so soft and gooey in the center Underbaking them! In case 8 minutes of baking time didn’t seems like enough, now you know why.

  • Chill the dough to keep each cookie tall and soft.

Very moist dough like this tends to spread quite a bit when baked. Now, it’s still pretty dense, so it’s not like you’ll have a totally flat, crisp cookie!

However, if you like to bite down into a tall, pillowy cookie, then I’d recommend chilling the dough for 30 minutes or so. 

It’ll limit the amount it spreads, keeping the dough balls (relatively) in the same shape while baking!

  • Get creative with the mix-ins!

There are so many great things you can throw into brownie cookies!!

Peanut butter chips are a great way to complement the flavors already in our Reeses Pieces cookies.

But if you want to change things up a little bit, I have a few suggestions.

First, nuts! Walnuts and peanuts are good for adding texture, too, and aren’t as sweet.

Then there are add-ins like butterscotch and caramel chips, marshmallow pieces, and even crumbles of other candy bars!

Storing and Freezing Reeses Cookies

This dough can be frozen for up to 18 months!

Whenever you’re prepared to bake them, just let the dough thaw in the fridge overnight, and you’re good to bake as directed in this recipe. 

Once baked, store Reeses Pieces cookies in an airtight container or freezer bag for up to a week.

They’re fine at room temperature, but keep in a cool, dry place if you don’t want the candies to melt! 

Kitchen Tools You Will Need

  • Baking Sheets lined with parchment paper – Used for anything from baked goods to roasting, a good baking pan will last for years.
  • 2 Tablespoon Scoop – Great for meatballs, balling cookie dough, ice cream, and portioning out leftovers. I’ve had this set for years and use them all the time.
  • Mixing Bowls – I like to have a variety of sizes on hand, and this set has them all.

Brownie Cookies Recipe FAQ

Why are my brownie cookies flat?

Very moist dough like this is going to result in treats a little flatter than average — but that’s okay! They’re also softer and chewier than others, so texture isn’t at all lost.

However, if you don’t like a flat cookie, you could add more dry mix and chill the dough before baking to keep them taller. 

Is the candy coating on Reese’s Pieces chocolate?

Nope! There actually isn’t any chocolate in the Pieces at all. It’s just a hard sugar shell. 

Still, they add an amazing texture to my cookie recipe. That crunchy sweetness brings the whole thing home!

What is the filling in Reese’s Pieces?

It’s peanut butter! There are some other sweeteners and preservatives in there as well, but the main ingredient is peanut butter. It’s really similar to the filling you find in the cups! 

Bear in mind that it’s very sweet. If you want more nuts and less sugar, you’re better off with one of our recommended alternatives such as peanuts or walnuts.

Donna’s Notes

Brownie cookies are soft and chewy. I like to under-bake my cookies for 8 minutes so they stay soft in the middle.
Cookies will continue to cook while they cool on the baking sheet.
