For the Base

  • 2 large Eggs Let them sit at room temperature for easier mixing.
For the Mix-Ins

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and prepare a 9x13-inch baking pan by greasing it with butter or lining it with parchment paper.
  2. In a large mixing bowl, combine the yellow cake mix, melted butter, vanilla extract, and room temperature eggs. Mix until a gooey, smooth dough forms.
  3. Gently fold the semi-sweet chocolate chips into the dough by hand.
  4. Spread the cookie dough into the prepared baking pan, creating a smooth surface.
  5. Sprinkle the Reese’s Pieces candies generously over the top of the dough and press them lightly into the mixture.
  6. Bake for 20-25 minutes until golden brown around the edges and slightly jiggly in the center.
  7. Allow the cookie bars to cool completely in the pan on a wire rack before slicing into squares.
