Ingredients
Scale
Cookie Dough
- ½ cup unsalted butter (softened)
- ½ cup light brown sugar
- ¼ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 2 tablespoons light corn syrup
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup dark cocoa powder (Hershey’s Special Dark recommended)
- 1¼ cup all-purpose flour
Chocolate Ganache
- ¾ cup semi-sweet chocolate chips
- ¼ cup heavy cream
Decoration
- Rainbow chip sprinkles
Instructions
- Preheat Oven: Set your oven to 350°F (175°C) to ensure it reaches the right temperature while you prepare your dough.
- Cream Butter and Sugars: In a large bowl, use an electric mixer on medium-high speed to cream the softened unsalted butter, light brown sugar, and granulated sugar together for 2 minutes until the mixture is light and fluffy.
- Add Wet Ingredients: Mix in the egg, vanilla extract, and light corn syrup on low speed just until combined. Scrape the sides of the bowl to incorporate all ingredients evenly.
- Add Leavening and Salt: Incorporate baking soda and salt by mixing for another 5-10 seconds until evenly blended throughout the batter.
- Add Cocoa and Flour: Gradually add the dark cocoa powder and all-purpose flour, mixing on medium speed until the dough comes together uniformly.
- Shape the Cookies: Using a ¼ cup scoop or measuring cup, scoop the dough out and roll into balls. Gently flatten each ball into a disc about ½ inch thick to encourage spreading during baking.
- Bake the Cookies: Place the discs on a baking sheet and bake in the preheated oven at 350°F for 11-12 minutes. Do not overbake; centers might look slightly wet but will firm up as they cool. Let cookies cool fully before decorating.
- Prepare Chocolate Ganache: Put semi-sweet chocolate chips into a medium heat-safe bowl. Heat the heavy cream in a microwave-safe container for 30-45 seconds until just bubbling or steam rises from stove heating.
- Combine Ganache Ingredients: Pour the hot cream over the chocolate chips without stirring initially. Press chips gently into the cream to fully submerge. Let sit for about 3 minutes.
- Stir to Smooth: After resting, stir the mixture with a fork until smooth and creamy. If chocolate hasn’t fully melted, microwave at 50% power in 10-second increments, stirring between each until smooth.
- Decorate Cookies: Spoon about 1 tablespoon of ganache onto each cooled cookie and sprinkle with rainbow chip sprinkles.
- Set Ganache: Refrigerate the decorated cookies for 30-60 minutes to harden the ganache and enhance fudginess.
- Storage Recommendations: Keep the cookies refrigerated for optimal texture and flavor; they taste even better when chilled. Alternatively, they can be stored at room temperature for up to two days.
Notes
- Do not overbake the cookies; centers should still be slightly soft before cooling to ensure fudgy texture.
- Flattening the cookie dough balls before baking helps them spread evenly and prevents them from becoming puffy.
- The ganache can be reheated gently in the microwave if it hardens too much before you finish decorating.
- For best results, refrigerate cookies after decorating to allow ganache to set and improve the fudgy consistency.
- Use a cookie scoop to achieve uniform cookie sizes for even baking.
