Step-by-Step Instructions
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures your cookies bake evenly and achieve that perfect fudgy texture.
Step 2: Prepare the Baking Sheets
Line two baking sheets with parchment paper. This prevents sticking and makes cleanup a breeze.
Step 3: Make the Cookie Dough
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes. Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can make the cookies tough.
Step 5: Fold in Chocolate Chips
Gently fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the dough.
Step 6: Shape the Cookies
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Step 7: Add Toppings
Before baking, top each cookie with a few mini marshmallows and rainbow sprinkles. Press them gently into the dough to ensure they stick.
Step 8: Bake
Bake in the preheated oven for 12-15 minutes, or until the edges are set but the centers are still soft. They will continue to cook slightly once removed from the oven.
Step 9: Drizzle with Chocolate
While the cookies cool, melt the remaining chocolate chips in a microwave-safe bowl. Use a fork to drizzle the melted chocolate over the cookies for an extra touch of indulgence.
Step 10: Cool and Serve
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. Enjoy your fudgy cosmic brownie cookies!
