Peanut Butter + Chocolate, all day, every day. At least that’s my husband’s motto – – and the rest of us clamor for it, too! So of course, these Peanut Butter Cup Cookies have been a win in our house. This easy cookie recipe features soft and chewy peanut butter cookies stuffed with a melty-gooey Reese’s cup. They’re so crazy good when enjoyed still a bit warm from the oven! I like to sprinkle some flaky sea salt over the top, like I do with our beloved chocolate peanut butter ritz cookies and homemade peanut butter cups – which definitely makes EVERYBODY happy!!

What You’ll Need

Here’s a look at the ingredients in these irresistible cookies. Find the exact ingredient amounts in the printable recipe card at the end of this post.

  • Butter – This adds rich texture and flavor. Make sure it’s fully softened so it incorporates smoothly with the brown sugar and peanut butter. 
  • Brown sugar – This adds delicious sweetness, plus extra moist texture.
  • Peanut butter – Classic, creamy peanut butter (such as Jif) is key to the cookie base.
  • Egg – To bind the cookie dough together and add rich flavor and texture.
  • Vanilla – Pure vanilla extract enhances the peanut butter cookie dough.
  • Flour – All-purpose flour adds structure to the cookie dough. Make sure to measure using the spoon and level method. 
  • Baking soda & baking powder – These leavening agents give the cookies a rise, plus keep them soft and chewy. 
  • Salt For a little flavor contrast in the sweetened dough.
  • Reese’s mini peanut butter cups – This popular candy adds a familiar chocolate + PB flavor to the cookies. So FUN!!
  • Sea salt flakes – This is optional, but highly recommended. I like to finish these cookies with a little sprinkle of Maldon sea salt flakes!

How To Make Peanut Butter Cup Cookies

See how to make these cookies in the photos below. Find the detailed instructions in the recipe card lower down.

  • Cream butter & sugar. First, cream the butter and sugar until light and fluffy.
  • Add peanut butter. Blend in the peanut butter, egg, and vanilla extract.
  • Combine dry ingredients. In another bowl, whisk together the dry ingredients.
  • Combine altogether. On low speed, beat the dry ingredients into the creamed mixture. Then place the dough in the fridge to chill for 15 minutes.
  • Portion cookie dough. Grease two mini muffin pans and form tablespoon-sized portions of dough (a scoop works great!). Roll the dough into balls and place in wells of the muffin pans.
  • Bake. Place muffin pans in the oven and bake for 8-10 minutes.
  • Add peanut butter cups! Remove the cookies from the oven and immediately press one mini Reese’s cup into the center of each soft cookie, then sprinkle with a little flaky sea salt (optional).

Tips for Success

A few best practices will ensure that these are the best, most chewy-soft peanut butter cup cookies ever. See my tips below.

  • Use regular peanut butter. It’s best to use a peanut butter such as Jif for this recipe, as natural peanut butter has a different texture, usually with oil separation.
  • Chill the dough. Because this cookie dough has a good amount of butter and peanut butter, it benefits from a brief rest in the fridge before it’s baked. Chilling helps the dough roll better.
  • Immediately press in the Reese’s cups. As soon as you remove the peanut butter cookies from the oven, be ready to press the Reese’s peanut butter cups into the warm, soft dough. If you wait until the cookies have cooled, the cups will not press in!
  • Sprinkle with salt right away, too. To help the sea salt flakes adhere to the cookie, sprinkle the salt as soon as you’ve finished pressing in the Reese’s cups.
  • Let cookies cool in pan. Then let the finished cookies cool completely before removing them from the pan. (Unless you simply can’t resist eating them all warm and gooey!!)

Proper Storage

If you have any Reese’s peanut butter cup cookies to store away, here’s how to keep them fresh-tasting for as long as possible:

  • Counter – Place cookies in an airtight container and store them on the counter at room temperature for up to 5 days.
  • Fridge – Place cookies in an airtight container and store them in the fridge for up to 10 days.
  • Freezer – Add cookies to a freezer-safe, airtight container and freeze for up to 3 months.

Ingredients

  • ½ cup unsalted butter, softened

  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • cups all-purpose flour
  • ½ teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon Morton kosher salt
  • 48 Reese's miniature peanut butter cups, unwrapped

Instructions

  • In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and brown sugar on medium speed until light and fluffy, about 2 minutes.

  • Bake for 8-10 minutes, or until the edges are just golden brown but the cookies are still soft.
