Ingredients

Scale

Primary Ingredients:

  • 1 cup all-purpose flour
  • ½ cup cocoa powder
  • ½ cup unsalted butter
  • 1 cup granulated sugar
  • ½ cup brown sugar
  • 2 large eggs

Supporting Ingredients:

  • 1 teaspoon vanilla extract
  • 1 teaspoon baking powder
  • ¼ teaspoon salt

Garnish:

  • ½ cup semi-sweet chocolate chips
  • ¼ cup rainbow sprinkles

Instructions

  1. Melt ½ cup (113g) unsalted butter in a saucepan over low heat at 180°F (82°C). Stir in 1 cup (200g) granulated sugar and ½ cup (100g) brown sugar until fully incorporated and glossy.
  2. Remove butter-sugar mixture from heat. Allow to cool for 3-4 minutes. Crack 2 large eggs into the pan and whisk 1 teaspoon vanilla extract until mixture becomes smooth and slightly lighter in color.
  3. Sift 1 cup (120g) all-purpose flour, ½ cup (50g) cocoa powder, 1 teaspoon baking powder, and ¼ teaspoon salt into a separate mixing bowl. Ensure no lumps remain.
  4. Gently fold dry ingredients into wet mixture using a silicone spatula. Mix until ingredients are just combined – your batter should look rich and dark chocolate brown.
  5. Sprinkle ½ cup (85g) semi-sweet chocolate chips across the batter. Fold chips in carefully without overmixing.
  6. Transfer batter to a parchment-lined 8×8-inch baking pan. Spread evenly with your spatula, ensuring corners are filled.
  7. Bake at 350°F (175°C) for precisely 27 minutes. Your toothpick should emerge with a few moist crumbs when inserted into the center.
  8. Remove from oven and let brownies cool completely for 45-60 minutes at room temperature. Sprinkle ¼ cup rainbow sprinkles across the top before slicing into 16 squares.

Notes

  • Check brownies at 25 minutes to prevent overbaking, as they continue cooking while cooling.
  • Use high-quality cocoa powder for richer chocolate flavor and deeper color.
  • For extra fudgy texture, replace one egg with 1/4 cup of sour cream or Greek yogurt.
  • Sprinkle rainbow chips or chocolate sprinkles on top to mimic classic cosmic brownie appearance.
