Reese's Pieces Oatmeal Chocolate Chip Cookies

Warm cookies fresh out of the oven have got to be my most favorite food of all time. And these Oatmeal Chocolate Chip cookies areĀ my all-time favorite cookie recipe (well, tied with these KAF Chocolate Chip Cookies). And believe me, I know my way around a chocolate chip cookie recipe, so you can trust me when I say these are THE BEST!

Plus: Reese’s Pieces. So really, there’s no way you could possibly go wrong here.

Now, I do have to add a disclaimer here– these are NOT Monster Cookies. (My husband asked me at least half a dozen times if these were Monster Cookies). If you are looking for a peanut butter-y Monster Cookie full of Reese’s goodness, head on over to this post. They’re awesome.

But these are just good ol’ fashioned oatmeal chocolate chip cookies packed with as many Reese’s Pieces as I could fit into my KitchenAid mixing bowl! Chewy, gooey, and full of melty chocolate and candy crunch in every single bite.

Enjoy šŸ™‚

PS- I love how Reese’s PiecesĀ are already perfectly colored for Fall bakingĀ ????!

  • 1 1/2 cups semisweet chocolate chips
  • 1 1/2 cupsĀ Reese's Pieces


Preheat oven to 325ºF.

Beat together the butter and sugar until smooth and creamy.

Mix in the egg, egg yolk, and vanilla, mixing well in between each addition.

In a large bowl, mix together the flour, oats, baking powder, baking soda, and salt. Add this dry mixture to the wet mixture. Mix until dough forms.
