Equipment

  • Measuring cups and spoons
  • 9 x 9-inch baking pan
  • Nonstick spray
  • Parchment paper
  • Large mixing bowl
  • Rubber spatula

Ingredients

  • 1 14.25-ounce box white cake mix
  • 1/3 cup butter melted
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup chocolate chips

Instructions

  • Preheat the oven to 350°F. Lightly spray a 9 x 9-inch baking pan with nonstick spray, then line it with parchment paper.
  • Add the cake mix, melted butter, eggs, and vanilla extract to a large mixing bowl. Mix until everything comes together into a thick cookie dough, about 1 to 2 minutes.
  • Fold in the chocolate chips.
  • Transfer the dough to the prepared baking pan and press it into an even layer. If the dough is sticky, lightly spray your hands or a rubber spatula with nonstick spray to make it easier to press into the pan.
  • Bake for 30 to 35 minutes, until the top is golden brown and the bars are set.
  • Allow the bars to cool in the pan for at least 15 minutes. Use the parchment paper to lift them out of the pan, then cut into 9 bars.

Notes

  • The dough should be thick and much denser than regular cake batter.
  • Be careful not to overbake the cookie bars, which can make them dry.
  • For an easy variation, substitute yellow or chocolate cake mix for the white cake mix.
  • Add 1/2 cup chopped walnuts, pecans, almonds, or pistachios along with the chocolate chips if desired.
  • Store cooled cookie bars in an airtight container at room temperature for 3 to 4 days.
  • To freeze, wrap the bars well and place them in a freezer-safe airtight container or freezer bag for up to 3 months. Thaw at room temperature before serving.
