How to Make Peanut Butter Reese’s Pieces Cookies
The best part of this recipe is that the dough does not have to be refrigerated before baking so you will have fresh baked cookies ready to eat in about 30 minutes. To start, preheat oven to 375 degrees. If desired line a baking sheet with parchment paper for easy clean up.
Then, in a large mixing bowl, using an electric hand mixer (or use a stand mixer), combine and cream together butter, peanut butter, sugar and brown sugar until light and fluffy. This should take about 2 minutes.
Next, add egg and milk and blend to combine. Then, add flour and baking soda. Add Reese’s Pieces and fold in with spatula or wooden spoon.
Drop by rounded tablespoon on baking sheet. I love to use a cookie scoop for this to make cookies that are the same size. If you have some additional reese’s pieces stick them into the balls of dough before baking so that you can see some on the top of the cookies. Bake at 375 degrees for 8 minutes.
Remove from oven and cool on wire rack. If you prefer your cookies to be firmer or a little crunchy go ahead and bake them for an extra minute or two. Store cookies in an airtight container.

Frequently Asked Questions
Absolutely! You can substitute the reese’s pieces for peanut butter chips, dark chocolate chips, mini reese’s pieces, chopped up peanut butter cups, semi-sweet chocolate chips or even just leave them out.
This peanut butter cookie recipe will stay soft for a few days after baking them. If you over bake cookies they will get a little bit harder. The combination of brown sugar and milk helps to keep these cookies super soft.
I would not recommend using crunchy peanut butter because you will not have enough peanut butter that is actually mixed into the cookie dough. This recipe has only been tested with creamy peanut butter.
Yes, we made smaller cookies with a tablespoon sized scoop but if you would like to make larger cookies just adjust the baking time to make sure they are baked through. You may need to up the baking time to 10-12 minutes depending on size.
