Ingredients List
To make your Monster Mash Brownies, you will need the following ingredients:
- 1 cup unsweetened cocoa powder: For that rich chocolate flavor.
- 2 cups granulated sugar: To sweeten the deal.
- 4 large eggs: Essential for binding.
- 1 teaspoon vanilla extract: For aromatic warmth.
- 1 cup all-purpose flour: To give structure.
- 1 teaspoon baking powder: To help them rise.
- 1/2 teaspoon salt: To enhance flavor.
- 1 cup chocolate chips: For extra gooeyness.
- Assorted candy eyes: To create the monster effect.
- Gummy worms: For that creepy touch.
Substitutions:
- Cocoa Powder: You can use Dutch-processed cocoa for a milder flavor.
- Sugar: Substitute with coconut sugar for a healthier option.
- Eggs: Flax eggs work as a vegan alternative.
- Flour: Whole wheat flour can be used for added fiber.
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Greasing your baking pan (a 9×13 inch works perfectly) with butter or lining it with parchment paper will ensure easy removal later.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the cocoa powder, sugar, and eggs. Use a whisk to blend until smooth. Add in the vanilla extract and melted butter (about 1/2 cup) for a richer flavor.
Step 3: Combine Dry Ingredients
In another bowl, whisk together the flour, baking powder, and salt. Gradually add this mixture to your wet ingredients, stirring gently until just combined. Be careful not to overmix!
Step 4: Fold in Chocolate Chips
Gently fold in the chocolate chips, ensuring they are evenly distributed throughout the batter for those gooey pockets of chocolate in every bite.
Step 5: Bake
Pour the brownie batter into your prepared baking pan and spread it evenly. Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 6: Cool and Decorate
Allow the brownies to cool in the pan for about 10 minutes before transferring them to a wire rack. Once cooled, cut them into squares and decorate with candy eyes and gummy worms for that monster effect!

Common Mistakes to Avoid

To keep your Monster Mash Brownies fresh:
- Store them in an airtight container at room temperature for up to 3 days.
