Rich, fudgy chocolate cookies with glossy ganache and colorful rainbow chip topping

# What You Need:

→ Cookie Dough

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

→ Topping

13 - 1/3 cup rainbow candy-coated chocolate chips

# How To Make:

01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, beat softened butter, granulated sugar, and brown sugar until light and fluffy, approximately 2-3 minutes.
03 - Beat in eggs one at a time until fully incorporated. Mix in vanilla extract.
04 - In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt until well blended.
05 - Gradually add dry ingredients to wet mixture, mixing just until combined. Avoid overmixing to prevent tough cookies.
06 - Scoop 2-tablespoon mounds of dough onto prepared baking sheets, spacing about 2 inches apart to allow for spreading.
07 - Bake for 9-11 minutes until edges are set and centers appear slightly underbaked for fudgy texture.
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 heatproof bowl. Heat heavy cream in 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 while ganache is still tacky.
11 - Allow ganache to set at room temperature for approximately 20 minutes before serving. For faster setting, refrigerate briefly.

# Expert Tips:

01 -
  • The fudgy center stays soft for days unlike cakey cookies that dry out
  • That ganache sets into something so smooth it reminds people of fancy bakery treats
  • The rainbow chips make everyone smile before they even take a bite
02 -
  • Overmixed dough makes cookies tough stop when flour just disappears
  • Underbaked centers look raw but firm up as they cool
  • Ganache must cool slightly before spreading or it runs off edges
03 -
  • Chill your baking sheets between batches to keep cookies from spreading too thin
  • Use a cookie scoop for uniform sizes that bake evenly
