Description

Thick, fudgy chocolate cookies topped with silky ganache and colorful candy-coated sprinkles, inspired by classic cosmic brownies. These bakery-style treats are rich, nostalgic, and completely irresistible.


Ingredients

115 g unsalted butter, softened

200 g granulated sugar

1 large egg

1 teaspoon vanilla extract

95 g all-purpose flour

40 g unsweetened cocoa powder

1/2 teaspoon baking powder

1/4 teaspoon salt

120 g semi-sweet chocolate chips

120 g semi-sweet chocolate, chopped (for ganache)

80 ml heavy cream (for ganache)

3 tablespoons rainbow candy-coated chocolate chips


Instructions

  1. Preheat oven to 175°C (350°F) and line a baking sheet with parchment paper.
  2. Cream together the softened butter and sugar in a large bowl until light and fluffy.
  3. Beat in the egg and vanilla extract until smooth and fully combined.
  4. Sift in the flour, cocoa powder, baking powder, and salt. Mix gently until a thick dough forms without overmixing.
  5. Fold in the semi-sweet chocolate chips until evenly distributed.
  6. Scoop dough into evenly sized balls and place on the prepared baking sheet, spacing them apart. Slightly flatten the tops.
  7. Bake for 10–12 minutes until edges are set and centers remain soft. Cool completely on the baking sheet.
  8. Heat heavy cream in a small saucepan until just steaming. Pour over chopped chocolate and let sit for 2 minutes, then stir until smooth and glossy.
  9. Spoon ganache over cooled cookies and spread to the edges. Sprinkle rainbow candy-coated chocolate chips on top while ganache is soft.
  10. Allow ganache to set before serving.

Substitute dark chocolate for a deeper flavor or milk chocolate for a sweeter taste.

Add chopped walnuts or pecans for extra texture.

Freeze for up to 2 months and thaw at room temperature before serving.

Microwave for 8–10 seconds to slightly soften ganache before serving.

Dough can be prepared ahead and refrigerated for up to 24 hours.
