Description

Inspired by the iconic treat, these bakery-style cookies feature a rich ganache filling and chewy chocolate base with a rainbow sprinkle finish.


Ingredients

For the Ganache:

3.5 oz (100 g) good-quality chocolate (mix of milk and semisweet recommended)

1/4 cup (60 g) heavy cream

For the Cookies:

2 cups (250 g) all-purpose flour

6 tbsp (40 g) Dutch-process cocoa powder

1 tsp baking soda

1/2 tsp kosher salt

4 oz (110 g) semisweet chocolate, melted and slightly cooled

3/4 cup (170 g) unsalted butter, room temp

1 cup (220 g) packed brown sugar

1/2 cup (100 g) granulated sugar

2 large eggs, room temp

2 tsp vanilla extract

Rainbow chips or sprinkles for topping


Instructions

Make the Ganache:

Place chopped chocolate in a heatproof bowl.

Heat cream until just bubbling, pour over chocolate, and let sit for 30 seconds.

Stir gently until smooth and combined.

Let cool for 20–30 minutes until peanut butter consistency.

Scoop into 1¼-inch mounds and freeze on a parchment-lined sheet for 30+ minutes.

2. Make the Cookie Dough:

Whisk together flour, cocoa, baking soda, and salt.

Beat butter and sugars until fluffy (2–3 minutes).

Mix in eggs one at a time, then vanilla.

Add melted chocolate and mix to combine.

Mix in dry ingredients until just incorporated.

Cover and chill dough for 20–30 minutes until firm.

3. Assemble the Cookies:

Preheat oven to 350°F (175°C); line baking sheets with parchment.

Divide dough into pairs of scoops; flatten each into disks.

Place frozen ganache center on one, top with second disk, seal edges, and shape into a puck.

Press the tops into rainbow chips.

Space on baking sheet 3–4 inches apart.

4. Bake:

Bake for 9–11 minutes, until puffed and set.

Swirl a round cookie cutter around the edges for perfectly round cookies.

Cool 10 minutes on pan, then transfer to rack.

Notes

Chocolate Variations: Use dark chocolate for a richer flavor or milk for sweetness.

Flavor Ideas: Add extracts (peppermint, orange) to ganache.

Decorations: Swap sprinkles for chopped nuts or chocolate drizzle.

Smaller Cookies: Use less dough and ganache; reduce bake time by 2–3 minutes.
