Ingredients

Scale

Base Ingredients

  • 15.25 oz cake mix, any flavor
  • 2 large eggs
  • ½ cup (113g) unsalted butter, melted
  • 1 tsp vanilla extract

Add-Ins

  • 1 ½ cups add-ins (such as chocolate chips, nuts, sprinkles, dried fruits, or candies)

Instructions

  1. Preheat the oven: Set your oven temperature to 350°F (175°C). Prepare a 9×13 inch baking pan by spraying it with nonstick spray to ensure easy removal of the cookies later.
  2. Mix the batter: In a mixing bowl, combine the cake mix, 2 large eggs, melted butter, and 1 tsp vanilla extract. Stir these together until just combined. Then fold in your choice of 1 ½ cups of add-ins. The batter will be thick and dense.
  3. Transfer and level: Pour the batter into the prepared baking pan. Use a spatula or your hands to evenly spread the batter all across the pan. If you want, sprinkle additional add-ins on top for extra texture and flavor.
  4. Bake the bars: Place the pan into the preheated oven and bake for 17 to 20 minutes. Look for the edges to puff up and start setting as a sign they’re done. Avoid overbaking to keep the bars moist.
  5. Cool and serve: Once baked, remove the pan from the oven and allow the bars to cool completely before cutting into squares. This helps the bars set properly for cleaner slices.

Notes

  • You can customize these bars with any add-ins such as chocolate chips, nuts, sprinkles, or dried fruit.
  • Make sure not to overbake to keep the bars soft and chewy.
  • If you prefer thicker bars, use a smaller pan or reduce the baking time slightly to prevent drying out.
  • These bars store well in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
  • For a gluten-free version, use a gluten-free cake mix and ensure your add-ins are gluten-free.
