Ingredients

Scale

Dry Ingredients

  • 2 cups plus 2 Tbsp all-purpose flour (270 g)
  • ½ cup plus 2 Tbsp Dutch processed cocoa powder (67 g)
  • ½ tsp espresso powder (optional but strongly suggested)
  • ½ tsp baking soda
  • ½ tsp baking powder
  • ½ tsp sea salt (or ¼ tsp salt if using salted butter)

Wet Ingredients

  • 1 cup salted butter (227 g, room temperature 65-67°F)
  • 1 cup white sugar (200 g)
  • ½ cup light brown sugar (110 g)
  • 2 large eggs (room temperature)
  • 1 ½ tsp vanilla extract

Ganache & Topping

  • 4 oz dark or semi-sweet chocolate (high quality baking chocolate or chocolate chips)
  • â…“ cup heavy whipping cream
  • Mini rainbow candy coated chips for topping


Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C) to prepare for baking the cookies.
  2. Combine dry ingredients: In a medium bowl, whisk together the flour, espresso powder, cocoa powder, sea salt, baking soda, and baking powder until evenly mixed.
  3. Cream butter and sugars: In a separate bowl or using a stand mixer, beat the room temperature butter with white and brown sugars until light and fluffy, about 3 to 4 minutes.
  4. Add eggs and vanilla: Beat in the eggs one at a time, then add the vanilla extract, mixing until fully incorporated.
  5. Incorporate dry mixture: Gradually add the flour mixture into the wet ingredients, about one-third at a time, mixing gently just until combined to avoid overmixing.
  6. Shape cookies: Using a 1 ½ tablespoon cookie scoop, portion the dough and roll into balls. Place them 2 inches apart on a parchment paper-lined baking sheet.
  7. Bake cookies: Bake for 7 to 10 minutes until the edges are set and the tops appear puffy. Eight minutes is optimal for the best texture.
  8. Shape cookies (optional): Remove cookies from the oven and use a biscuit or cookie cutter to press them into even, round shapes. Let them cool on the baking sheet for several minutes before transferring them to a wire rack to cool completely.
  9. Prepare ganache: Chop the dark chocolate and place it in a small bowl. Heat the heavy cream in the microwave in 20-second intervals until hot but not boiling, about 40 seconds total.
  10. Make ganache: Pour the hot cream over the chopped chocolate and let sit for a few minutes. Stir gently until smooth and fully melted. If needed, warm briefly in the microwave for 5-10 seconds and stir again.
  11. Top cookies: Spoon roughly ¾ teaspoon of ganache onto each cooled cookie. Immediately sprinkle mini candy-coated chips or rainbow sprinkles on top to decorate.
  12. Set and serve: Allow cookies to set for about 1 hour before serving, or enjoy them immediately for a gooier texture.

Notes

  • Use high-quality cocoa and chocolate for the best rich chocolate flavor.
  • Espresso powder enhances the chocolate depth but is optional.
  • If using salted butter, decrease added salt to avoid over-salting.
  • Pressing cookies with a cutter after baking creates uniform round shapes but is optional.
  • Ganache can be reheated gently if it hardens before spreading.
  • These cookies keep well in an airtight container for up to 4 days.
