These Reese’s pieces peanut butter cookies are loaded with peanut butter, Reese’s pieces, milk chocolate chips and peanut butter chips. These might possibly be the most perfect peanut butter cookie.
I shared the recipe for these Reese’s Pieces peanut butter cookies over nine years ago and am brining them back into the spotlight today because they deserve a chance to shine again and desperately needed some updated photos.
When I pulled up this recipe to update it I laughed as I read the original post because this is what it said:
I'm back from a fun-filled, food-filled, girls trip to Arizona. On Monday, I left blue skies, clean air and temps in the upper 70s and came home to mostly blue skies, an inversion and temps in the upper 30s. I think I like Arizona much better than Utah right now.
These cookies were part of our food-filled trip. I had made them right before I left on my trip and they were so good I had to make some for my mom, sister and aunts. They fell in love with the cookies (and the dough), just like my boys did.
I made them again yesterday which makes three times in one week. I'm a peanut butter fanatic so these cookies rank right at the top of my list. Soft, full of peanut butter, Reese's pieces, peanut butter chips and chocolate chips . . . simply delicious!
Funny that nine years later I still feel the same about Utah weather and I am still making cookies way too many times in a week! BTW, it’s April my friends and Utah was hit with a massive snowstorm yesterday. . . do you see why I like Arizona weather better (lol)?!

These cookies are soft, tender and kinda melt in your mouth. Be sure not to over bake them, unless of course you are a fan of hard, crunchy cookies.
These cookies are a peanut butter lovers dream! They’re packed with peanut butter, peanut butter chips, Reese’s pieces. I definitely didn’t skimp on the peanut butter flavor in these cookies.

Peanut butter coming at you three ways . . .
- Peanut butter: The star of the show here for the delivery peanut butter flavor. I use creamy peanut butter, but you can use crunchy if you prefer.
- Peanut butter chips: My favorite brand is the Reese’s brand, you can use store brand, but I don’t think they’re as good. These add another layer of peanut butter flavor.
- Reese’s pieces: These add additional peanut butter flavor to these cookies, as well as give a little extra crunch from their candy coating. You can use mini or regular size Reese’s pieces.
Can I Make the Cookie Dough Ahead of Time?
- Sure! If you don’t want to bake the cookies right away, simply make the dough and refrigerate or freeze it. Scoop out balls of dough onto a parchment paper-lined baking sheet. Place the dough balls into the fridge freezer to become more solid (about an hour). Store the balls of dough in freezer-safe zipper bags either in the fridge for up to 5 days or put in the freezer until you are ready to bake. Be sure and label and date the bag.
- You can bake them right from the fridge or frozen. Pull the dough balls and out and place them on your prepared cookies sheet while your oven preheats. If baking from the fridge, add about a minute of baking time; if baking from the freezer add more like 2 to 3 minutes.

How to Store Reese’s Pieces Peanut Butter Cookies
These cookies can be stored at room temperature in an airtight container for up to one week. You can also freeze them in a freezer-safe container or Ziploc bag for up to to six weeks.
If you are a peanut butter lover like we all are, then you really need to make these cookies!

- 1 egg
- 1 teaspoon vanilla
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt

- Using a cookie scoop, scoop cookie dough (about 2 tablespoons) onto a cookie sheet lined with parchment paper or a silpat liner. Bake for 8-9 minutes. Don’t overbake (the cookies should look undercooked when you take them out). Gently tap/bang the cookie sheet on the counter a couple times and then allow the cookies to rest on cookie sheet for about 2 to 3 minutes. Transfer to a cooling rack.
Notes
- If you can’t find the mini Reese’s pieces, (not sure if they still make them) just substitute the regular size Reese’s pieces and use 1 1/2 cups.
- If you like your cookies a little flatter, you can gently flatten the cookies with the palm of your hand before you bake them.
- Feel free to use semisweet chocolate chips instead of milk chocolate.
