Monster Cookie Fudgy Brownies combine two classic treats into one seriously addictive dessert that will make your friends beg for the recipe. Packed with peanut butter, chocolate chips, and M&Ms, these brownies deliver a crazy-good flavor explosion that disappears faster than you can slice them.


Ingredients

Scale

Main Ingredients:

  • 1 cup granulated sugar
  • 1 cup brown sugar
  • ¾ cup all-purpose flour
  • ½ cup creamy peanut butter
  • ½ cup unsalted butter, melted
  • ½ cup unsalted butter, softened
  • ½ cup semi-sweet chocolate chips
  • ½ cup mini M&M’s
  • ½ cup chocolate chips
  • ½ cup rolled oats

Supporting Ingredients:

  • 3 large eggs
  • 1 egg yolk
  • ¾ cup unsweetened cocoa powder
  • ½ cup all-purpose flour
  • 2 teaspoons vanilla extract

Enhancing Ingredients:

  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ¼ teaspoon salt

Instructions

  1. Prepare an 8×8-inch (20×20 cm) baking pan by lining it with parchment paper. Ensure paper edges hang over sides for easy removal. Set oven temperature to 350°F (175°C).
  2. Melt ¾ cup (170 g) unsalted butter completely. Whisk 1 cup (200 g) granulated sugar, ½ cup (100 g) brown sugar, 2 large eggs, and 1 extra egg yolk until smooth and glossy.
  3. Sift ¾ cup (90 g) all-purpose flour, ¾ cup (75 g) unsweetened cocoa powder, and ½ teaspoon salt into the wet mixture. Stir gently until just combined. Add ½ cup (85 g) semi-sweet chocolate chips.
  4. Spread brownie batter evenly across the prepared pan using a spatula. Make sure corners and edges are covered.
  5. In a separate bowl, cream ½ cup (113 g) softened unsalted butter, ½ cup (100 g) brown sugar, and ¼ cup (50 g) granulated sugar until light and fluffy.
  6. Mix ½ cup (125 g) creamy peanut butter into the butter mixture. Add 1 large egg and 1 teaspoon vanilla extract. Blend thoroughly.
  7. Incorporate ¾ cup (90 g) all-purpose flour, ½ cup (45 g) rolled oats, ½ teaspoon baking soda, and ¼ teaspoon salt. Mix until just combined.
  8. Fold ½ cup (85 g) mini M&M’s and ½ cup (85 g) chocolate chips into the monster cookie dough.
  9. Drop spoonfuls of monster cookie dough across the brownie layer. Use a knife to create gentle swirls, keeping some brownie visible.
  10. Bake at 350°F (175°C) for 32-35 minutes. Check doneness with a toothpick – it should have a few moist crumbs when removed.
  11. Allow brownies to cool completely in the pan before lifting out using parchment paper edges. Cut into squares and serve.

Notes

  • Use room temperature eggs and butter for the smoothest, most even batter consistency.
  • Fold chocolate chips and M&M’s gently to prevent overmixing and maintain a tender brownie texture.
  • Line the baking pan with parchment paper for easy removal and clean slicing of brownies.
  • For gluten-free adaptation, swap all-purpose flour with a cup-for-cup gluten-free flour blend, ensuring the same rich, fudgy result.
