  • Author: Lila
  • Total Time: 40 minutes
  • Yield: 12 servings 1x

Description

Delightful and easy-to-make M&M Cookie Bars featuring a classic vanilla cake mix base combined with colorful red and green M&M’s, baked to golden perfection. These bars are perfect for holiday treats, parties, or whenever you crave a sweet and festive dessert.


Ingredients

Scale

Dry Ingredients

  • 1 box (15.25 oz) vanilla cake mix

Wet Ingredients

  • 2 large eggs
  • 1/2 cup (1 stick) unsalted butter, melted

Add-ins

  • 2 cups M&M’s (red and green)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350 degrees F. Spray a 9×9-inch baking pan with nonstick spray and line the bottom with parchment paper, allowing the ends to hang over two sides. This makes it easier to lift out the cookie bars after baking.
  2. Mix Ingredients: In a large bowl, combine the vanilla cake mix, eggs, and melted butter. Stir until the mixture is well blended. Then fold in the 2 cups of red and green M&M’s until evenly distributed.
  3. Spread Dough: Transfer the cookie dough into the prepared baking pan. Use a spatula to spread and pat down the dough evenly and level the top for uniform baking.
  4. Bake: Place the pan in the preheated oven and bake for 25 to 35 minutes. The cookie bars should be golden brown on top. To check doneness, insert a toothpick in the center; it should come out clean or with a few crumbs but no raw batter.
  5. Cool: Remove the pan from the oven and allow the cookie bars to cool completely in the pan. Cooling helps the bars firm up for easy cutting.
  6. Serve: Lift the cooled cookie bars out of the pan using the parchment paper handles. Cut into bars of your desired size and serve.

Notes

  • You can substitute M&M’s colors depending on the occasion, for example, pastel M&M’s for Easter or classic colors for everyday treats.
  • Be sure to let the bars cool completely to prevent them from falling apart when cutting.
  • If you prefer softer bars, reduce baking time slightly and monitor closely starting at 23 minutes.
  • Storage: Store bars in an airtight container at room temperature for up to 5 days or freeze for longer storage.
