# What You'll Need:
→ Cookie Components
01 - 1 cup unsalted butter, softened
02 - 1 cup granulated sugar
03 - 1/2 cup light brown sugar, packed
04 - 2 large eggs
05 - 2 teaspoons vanilla extract
06 - 1 1/4 cups all-purpose flour
07 - 1 cup unsweetened cocoa powder
08 - 1/2 teaspoon baking soda
09 - 1/4 teaspoon salt
→ Chocolate Ganache
10 - 1 cup semi-sweet chocolate chips
11 - 1/2 cup heavy cream
12 - 1 tablespoon unsalted butter
→ Decorative Topping
13 - 1/3 cup rainbow candy-coated chocolate chips
# How-To Steps:
01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, beat butter, granulated sugar, and brown sugar until light and fluffy, approximately 2-3 minutes.
03 - Add eggs one at a time, beating thoroughly after each addition. Stir in vanilla extract.
04 - In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt until well blended.
05 - Gradually incorporate dry ingredients into wet mixture, mixing just until combined. Avoid overmixing.
06 - Scoop 2-tablespoon portions of dough onto prepared baking sheets, spacing 2 inches apart.
07 - Bake for 9-11 minutes until edges are set and centers appear slightly underbaked.
08 - Let cookies rest on baking sheets for 5 minutes, then transfer to wire rack to cool completely.
09 - Place chocolate chips and butter in a heatproof bowl. Heat cream in a small saucepan until just simmering, then pour over chocolate. Let stand 2 minutes, then stir until smooth and glossy. Cool 5-10 minutes until slightly thickened.
10 - Spread 1 tablespoon ganache over each cooled cookie. Immediately sprinkle with candy-coated chocolate chips.
11 - Allow ganache to set at room temperature for approximately 20 minutes before serving.
# Expert Tips:
01 -
- The cookie base stays incredibly fudgy for days, unlike traditional brownies that dry out
- That glossy ganache transforms ordinary cookies into something that looks bakery fancy
- Subtly underbaking them creates this crackly edge and gooey center situation
02 -
- Overmixing the flour makes tough cookies so stop as soon as everything comes together
- The ganache needs to cool and thicken slightly before spreading or it will run right off the edges
- Adding the rainbow chips immediately is crucial because the ganache sets up fast
03 -
- Chill the dough for 30 minutes if your kitchen is warm to prevent spreading too thin
- Use a cookie scoop for uniform portions so they all bake at the same rate
