Creating your Halloween Eyeball Brownies is a fun and engaging process! Follow these steps to achieve spooktacular results:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper for easy removal.

2. Melt the Butter: In a medium saucepan over low heat, melt the unsalted butter. Once melted, remove from heat and let cool slightly.

3. Mix Sugar and Eggs: In a large mixing bowl, combine the melted butter with granulated sugar. Stir until well combined. Add the eggs one at a time, mixing thoroughly after each addition.

4. Add Vanilla Extract: Stir in the vanilla extract, mixing until it’s fully incorporated.

5. Combine Dry Ingredients: In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.

6. Pour the Batter: Spread the brownie batter evenly into the prepared baking pan.

7. Bake: Place the pan in the preheated oven and bake for 30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

8. Cool the Brownies: Once baked, remove the brownies from the oven and let them cool in the pan for about 15 minutes. Then, transfer them to a wire rack to cool completely.

9. Prepare Eyeballs: While the brownies cool, prepare the edible eyeballs by melting candy melts or using pre-made eyeball candy.

10. Decorate: Once the brownies are fully cooled, cut them into squares. Place one edible eyeball on top of each brownie square. If desired, use red icing to draw a bloodshot effect around the eyeballs.

These simple yet effective steps will have your Halloween Eyeball Brownies ready to delight and scare!
