Ingredients

Scale

Wet Ingredients

  • 1 cup unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder

Add-ins and Decorations

  • 1/2 cup dark chocolate chips
  • Green food coloring
  • Purple food coloring
  • Halloween-themed sprinkles (optional)

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper for easy removal and cleanup.
  2. Melt butter and sugar: In a large mixing bowl, combine the melted unsalted butter and granulated sugar. Beat them together until well incorporated.
  3. Add eggs and vanilla: Add the eggs one at a time to the butter and sugar mixture, beating well after each addition to ensure they are fully incorporated. Stir in the vanilla extract thoroughly.
  4. Combine dry ingredients: In a separate bowl, sift together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder to remove lumps and evenly distribute the leavening agents.
  5. Mix dry into wet: Gradually stir the dry ingredients into the wet ingredients until just combined. Avoid overmixing to keep the brownies tender. Fold in the dark chocolate chips evenly.
  6. Color the batter: Divide the brownie batter into two equal portions. Add green food coloring to one portion and purple food coloring to the other, mixing well until you achieve vibrant, uniform colors.
  7. Create marbled batter: Pour both colored batters alternately into the prepared baking pan. Use a toothpick or knife to swirl the two colors together, creating a marbled, witch’s brew effect.
  8. Bake: Place the pan in the preheated oven and bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs attached.
  9. Cool and decorate: Allow the brownies to cool completely in the pan. Once cooled, cut into squares. If desired, sprinkle Halloween-themed decorations on top for an extra festive touch.

Notes

  • Do not overmix the batter to keep the brownies fudgy and tender.
  • Use gel food coloring for more vibrant colors without thinning the batter.
  • Allow brownies to cool completely before cutting to get clean slices.
  • For an extra chocolate boost, add chopped nuts or more chocolate chips if preferred.
  • Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
