Instructions

Prepare the Cookie Dough: In a large bowl, cream together the butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy, about 2-3 minutes. Beat in the eggs one at a time, then mix in the vanilla extract.
Combine Dry Ingredients: In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add the dry mixture to the wet mixture, mixing just until incorporated. Do not overmix.
Scoop and Bake: Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper. Scoop the dough by rounded tablespoons onto the prepared sheets, leaving space between each. Bake for 10-12 minutes, or until the edges are set but the centers are still soft. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Make the Ganache: Place the chocolate chips in a heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until just simmering (do not boil). Pour the hot cream over the chocolate chips, let sit for 1-2 minutes, then stir until smooth and glossy.
Assemble the Cookies: Once the cookies are completely cool, spoon a dollop of ganache onto each cookie and gently spread it to cover the top.
Add the Cosmic Toppings: Immediately after glazing with ganache, sprinkle each cookie generously with rainbow candy-coated chocolate chips. Let the ganache set before serving (you can refrigerate briefly to speed up this process).

Notes

For extra-fudgy cookies, err on the side of underbaking slightly.
If you can’t find mini rainbow chips, chopped mini M&M’s or colorful sprinkles work in a pinch.
Cookies can be stored at room temperature in an airtight container for up to 4 days.
Chilling the dough for 30 minutes before baking results in a slightly thicker cookie.
