These Peanut Butter Cup Cookies have a soft, chewy texture with a strong peanut butter flavor. Each cookie is topped with a mini peanut butter cup that melts slightly into the center, adding a smooth chocolate contrast. The cake mix base keeps the dough easy to work with while still baking up with a homemade feel.

I use this Cake Mix Peanut Butter Cookie base a lot because it’s reliable and easy to work with. It’s the same base I’ve used in more than 5 cookie recipes on the blog, including my Spider Peanut Butter Cookies, and it holds up well when you add toppings or shape the dough.

For these, I bake the dough in a mini muffin pan like my Reindeer Cookie Cups and press a Reese’s peanut butter cup into the center right after baking. Chocolate and peanut butter are one of my favorite combinations, and this is a simple way to bring those flavors together in a soft cookie.

Ingredients

  • Creamy peanut butter – Adds the main peanut butter flavor and helps create a soft texture.
  • Eggs – Help bind the dough and give the cookies structure.
  • Vegetable or canola oil – Keeps the cookies moist and tender as they bake.
  • Yellow cake mix – Provides sweetness and forms the base of the dough. I used Duncan Hines.
  • Miniature peanut butter cups – Add a chocolate center that pairs with the peanut butter cookie base.

How to Make Mini Peanut Butter Cup Cookies

  1. Prep – Preheat the oven to 350°F and grease a mini muffin pan.
  2. Mix wet ingredients – In a large bowl, stir together the peanut butter, eggs, and oil until smooth.
  3. Add cake mix – Mix in the yellow cake mix until a thick dough forms.

Variations and Substitutions

  • Chocolate cake mix – Swap the yellow cake mix for chocolate cake mix for a deeper chocolate flavor.
  • Crunchy peanut butter – Use in place of creamy peanut butter to add texture.
  • Different candy centers – Try chocolate kisses or caramel-filled chocolates instead of peanut butter cups.
  • Pre-made refrigerated dough – Use store-bought peanut butter cookie dough instead of the cake mix base to save time.

Tips for Success

  • No-stir peanut butter – Keeps the dough consistent and prevents excess oil from affecting the texture.
  • Mix wet ingredients first – Blending the peanut butter, eggs, and oil until smooth makes it easier to incorporate the cake mix evenly.
  • Use a 1 tablespoon scoop – Keeps the cookies uniform so they bake at the same rate.
  • Press immediately after baking – Add the peanut butter cups while the cookies are still warm, so they settle into the center.
  • Cool completely in the pan – Allows the cookies to set fully so they don’t fall apart when removed.
