Ingredients
  

Wet Ingredients

  • 1 cup Butter Melted; unsalted recommended
  • 2 cups Brown Sugar Use light or dark
  • 4 large Eggs Room temperature
  • 2 tsp Vanilla Extract Pure for best flavor

Dry Ingredients

  • 1 cup All-purpose Flour No substitutions necessary
  • 1/2 cup Cocoa Powder Unsweetened
  • 1/2 tsp Salt Enhances flavor

Fun Ingredients

  • 1 cup Chocolate Chips You can mix semi-sweet and dark
  • 1 cup Peanut Butter Chips For a peanut butter flavor boost
  • 1/2 cup M&M's (or similar candy) Choose your favorite colors
  • 1/2 cup Oats Old-fashioned oats recommended

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
  • In a large bowl, mix the melted butter and brown sugar until well combined.
  • Add the eggs and vanilla extract, stirring until smooth.
  • In another bowl, whisk together the flour, cocoa powder, and salt.
  • Gradually add the dry ingredients to the wet mixture until combined.

Baking

  • Stir in the chocolate chips, peanut butter chips, M&M's, and oats until evenly mixed.
  • Pour the batter into the prepared baking pan and spread it evenly.
  • Bake for 25-30 minutes or until a toothpick inserted comes out with a few moist crumbs.
  • Allow to cool before slicing into squares and serving.

Notes

Ensure your butter is fully melted for a smooth batter. Use room-temperature eggs to help achieve better consistency. Don’t overmix the batter after adding flour to keep brownies fudgy. Experiment with adding nuts for extra crunch.
