Ingredients
Scale
Cookie Dough
- 1 cup salted butter (slightly softened)
- 2 cups light brown sugar (packed)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 2 large eggs (room temperature)
- 1 tablespoon vanilla extract
- 2 ¾ cups (390 g) all-purpose flour
- 2/3 cup (57 g) Dutch-processed unsweetened cocoa powder
Ganache and Topping
- 2/3 cup heavy whipping cream
- 2 cups semi-sweet chocolate chips
- 1 handful rainbow candy-coated chocolate chips
Instructions
- Preheat and prepare baking sheets: Preheat the oven to 350°F (175°C). Line three baking sheet pans with parchment paper and set aside to ensure easy removal of the cookies and prevent sticking.
- Cream butter and sugar: In a large mixing bowl, use an electric handheld or stand mixer fitted with a paddle attachment to cream together the softened butter, light brown sugar, baking powder, baking soda, and salt. Beat for about 2 minutes until the mixture is light, fluffy, and well combined.
- Add eggs and vanilla: Add the eggs one at a time, along with the vanilla extract, mixing thoroughly after each addition. Scrape down the sides of the bowl as needed to ensure even mixing.
- Incorporate dry ingredients: Gradually add the all-purpose flour and Dutch-processed cocoa powder into the wet mixture. Mix just until combined and no dry streaks remain—avoid overmixing to keep the cookies tender.
- Portion dough onto sheets: Using a cookie scoop or spoon, form dough balls about 2 tablespoons each. Arrange 12 dough balls per baking sheet, spacing them a few inches apart to allow for spreading.
- Bake cookies: Bake in the preheated oven for 10 minutes, or until the cookies are slightly puffed with set edges but still soft in the center. Be careful not to overbake to maintain a fudgy texture.
- Cool cookies: Let the cookies cool on the baking sheets for 5 minutes to set before transferring them to a wire rack to cool completely. This helps prevent overbaking and dryness caused by residual heat.
- Optional shaping: Immediately after baking, gently press the tops of slightly domed cookies with a flat-bottomed glass to level them, creating an even thickness which makes frosting easier and enhances the fudge center.
- Prepare ganache: Place the semi-sweet chocolate chips in a medium heatproof bowl. Heat heavy cream in a small saucepan over medium heat until steaming with small bubbles forming around the edges. Pour the hot cream over the chocolate chips, fully submerging them, and let sit for 2–3 minutes.
- Mix ganache: Stir or whisk the chocolate and cream mixture until smooth, glossy, and fully combined. If it thickens too much during decorating, gently reheat in the microwave for 10 to 15 seconds to restore spreadability.
- Assemble cookies: Spread a dollop of ganache on each cooled cookie, then sprinkle with rainbow candy-coated chocolate chips for a colorful, crunchy finish.
- Serve: Enjoy the cookies while the ganache is soft or let them sit at room temperature for about 1 hour until the ganache sets to a firm yet creamy texture.
Notes
- Use room temperature eggs for better mixing and a more consistent batter texture.
- Do not overbake; cookies should be soft in the center to maintain a brownie-like fudgy texture.
- Pressing the cookie tops after baking helps create an even surface for frosting and enhances the fudge center.
- If ganache becomes too thick during assembly, gently reheat to soften for easier spreading.
- Store cooled cookies in an airtight container at room temperature for up to 3 days.
