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

  1. Preheat Oven: Set your oven to 350°F (175°C) to ensure it reaches the right temperature while you prepare your dough.
  2. 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.
  3. 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.
  4. Add Leavening and Salt: Incorporate baking soda and salt by mixing for another 5-10 seconds until evenly blended throughout the batter.
  5. Add Cocoa and Flour: Gradually add the dark cocoa powder and all-purpose flour, mixing on medium speed until the dough comes together uniformly.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.
  11. Decorate Cookies: Spoon about 1 tablespoon of ganache onto each cooled cookie and sprinkle with rainbow chip sprinkles.
  12. Set Ganache: Refrigerate the decorated cookies for 30-60 minutes to harden the ganache and enhance fudginess.
  13. 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.
