# What You'll Need:
→ Cookie Base
01 - 1 cup (225 g) unsalted butter, softened
02 - 1 cup (200 g) granulated sugar
03 - 1/2 cup (100 g) light brown sugar, packed
04 - 2 large eggs
05 - 2 teaspoons vanilla extract
06 - 1 1/4 cups (160 g) all-purpose flour
07 - 1 cup (85 g) unsweetened cocoa powder
08 - 1/2 teaspoon baking soda
09 - 1/4 teaspoon salt
→ Chocolate Ganache
10 - 1 cup (170 g) semi-sweet chocolate chips
11 - 1/2 cup (120 ml) heavy cream
12 - 1 tablespoon unsalted butter
→ Topping
13 - 1/3 cup (50 g) rainbow candy-coated chocolate chips
# Directions:
01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy (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.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until combined. Do not overmix.
06 - Scoop 2-tablespoon mounds of dough onto prepared baking sheets, spacing about 2 inches apart.
07 - Bake for 9-11 minutes, until edges are set and centers look slightly underbaked.
08 - Let cookies cool on the baking sheets for 5 minutes, then transfer to a 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 sit 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 (about 20 minutes) before serving.
# Expert Hints:
01 -
- These cookies capture everything we loved about those vending machine brownies but with real ingredients and actual fudgy texture
- The ganache sets up perfectly firm so you can stack them for lunchboxes or care packages without them sticking together
- One batch makes 16 cookies which is honestly the perfect amount for sharing or keeping all to yourself during a Netflix marathon
02 -
- Underbaking these cookies by about 30 seconds makes all the difference between fudgy and dry so trust your eyes over the timer
- Room temperature ingredients matter here because cold butter will not cream properly giving you dense cookies instead of chewy ones
03 -
- Weighing your cocoa powder rather than scooping it prevents accidentally packing down too much which leads to dry cookies
- Room temperature dough spreads more so if your cookies are flattening too much try chilling the baking sheet for 10 minutes before they go in the oven
