Chocolate Peanut Butter Awesomeness

Can you ever have enough chocolate peanut butter options? From classic Buckeyes to Buckeye Brownies and Peanut Butter Pretzel Buckeyes, I love it all.

From salty-sweet options like Chocolate Peanut Butter Cup Pretzel Popcorn to Peanut Butter Swirled Chocolate Zucchini Bread, Peanut Blossom Cookies, Peanut Butter Oreo Cookie Balls, and last but not least, rich and decadent Chocolate Cake with Peanut Butter Frosting, there’s nothing that beats a terrific chocolate + peanut butter combo.

Are you sick of cookie recipes yet? No? Good, because I have a few more to share with you before December is over.

Also, I don’t think we could remain friends if you got tired of cookies. Who gets tired of cookies?

These Chocolate Reese’s Pieces Cookies start with a batch of my favorite chocolate cookie dough. You’ll just swap in a generous handful or two of Reese’s Pieces in place of the original chocolate chips.

In fact, I love this combination so much I might not ever put regular chocolate chips in my chocolate cookie dough anymore. I’ve never been able to resist a chocolate peanut butter combination.

Chewy Chocolate Cookies with Reese's Pieces

Like so many delicious things, these cookies begin with butter and sugar. Then, beat in eggs and vanilla.

Next, you’ll add the dry ingredients: flour, cocoa, baking soda, salt, and a special ingredient, cornstarch. The cornstarch helps keep these cookies super thick and soft.

Last, you’ll stir in the candies and chill the dough. I like to make the dough the night before and then bake them the next day. Just be sure to include at least a couple of hours to chill the dough. Chilling is important so the cookies don’t spread too much.

The Reese’s Pieces add a nice crunch and change of texture and are super easy to throw in. These cookies would be perfect for birthdays, Christmas cookie trays, or just every day awesome snacking. Let me know if you make them!

    Oh yum! I do love Reese’s Pieces and never thought to add these to my cookies. Your recipe is so nice and easy to follow, especially for beginner bakers like me.

    Are you using salted or unsalted butter? Usually recipes say unsalted otherwise it is assumed to use salted. But I see you add salt here, so I’m not sure now. Thanks!

    I will not be making these cookies again. I followed the recipe exactly and the dough was so dry that with the addition of the reese’s they were so difficult to roll. They didn’t really spread at all and I ended up with chocolate “cookie” balls. Not what I was looking for.

    Made the recipe today & it was pretty good. I could’ve used some mini Reese’s cups to the mixture to being out some extra peanut butter flavor. Definitely pay attention to the time baking in the oven. I did 9min cookies 1st tray & then 8min second tray. I think 7min would’ve been good. Every oven is different.
