1. Preheat the Oven and Prepare the Pan

• Preheat your oven to 175°C (350°F).
• Line a 9×13-inch baking pan with parchment paper or lightly grease it to prevent sticking.

2. Combine Wet Ingredients

• In a large mixing bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth and glossy.
• Add eggs, one at a time, mixing well after each addition.
• Stir in vanilla extract.

3. Add Dry Ingredients

• Sift in cocoa powder, flour, baking powder, and salt.
• Fold the dry ingredients into the wet mixture using a spatula until just combined.

4. Stir in Chocolate Chips

• Gently fold in the chocolate chips or chunks to ensure even distribution throughout the batter.

5. Pour Batter into the Pan

• Pour the brownie batter into the prepared pan and smooth the top with a spatula or offset knife.

6. Decorate with Toppings

• Lightly press in half the mini eggs, candy-coated chocolates, and marshmallows onto the surface.

7. Bake the Brownies

• Bake for 28–32 minutes or until a toothpick inserted in the center comes out with moist crumbs (not wet batter).

8. Cool and Finish Decorating

• Let the brownies cool in the pan for 10–15 minutes.
• While still warm, add the remaining mini eggs, candies, and marshmallows so they stick without melting.

9. Optional Final Touches

• Drizzle with melted white chocolate, add pastel sprinkles, or dust with edible glitter for extra flair.

10. Slice and Serve

• Allow brownies to cool completely before slicing into 16 squares.
• Serve on a festive platter or package individually for gifts.
