Ingredients
  

  • For the Bars:
  • 1 box yellow cake mix
  • 2 large eggs
  • ½ cup butter softened
  • 2 cups M&M’s red, white & blue for a festive look
  • Optional Garnish:
  • Extra candies or sprinkles on top
🧰 Tools You’ll Need
  • 9 ×13-inch baking pan
  • Parchment paper
  • Mixing bowl
  • Spatula or spoon
  • Pro Tip: Line your pan with parchment paper for easy removal—no sticking no stress.

Method
 

    1. Preheat & Prep

    Set your oven to 350°F (175°C). Grease your baking pan and line it with parchment paper, leaving a bit of overhang for easy lifting later.

    2. Mix the Base

    In a bowl, combine cake mix, eggs, and softened butter. Stir until you get a thick, smooth dough.

    3. Fold in the Candy

    Add M&M’s and gently mix until evenly distributed. Try not to overmix—this keeps your bars soft and chewy.

    4. Spread & Bake

    Press the dough evenly into your prepared pan. Bake for 20–25 minutes, or until the edges turn lightly golden.

    5. Cool & Slice

    Let the bars cool slightly, then lift them out using the parchment paper. Cut into squares and serve!
