Ingredients
Scale
Dry Ingredients
- 2 cups plus 2 Tbsp 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 if using salted butter and prefers less salt)
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
- 4 oz dark or semi-sweet chocolate (high quality baking chocolate preferred but chips are fine)
- ⅓ cup heavy whipping cream
Topping
- Mini rainbow candy coated chips for topping (or rainbow sprinkles)
Instructions
- Preheat the oven: Preheat your oven to 350°F to prepare for baking the cookies evenly.
- Mix dry ingredients: In a medium bowl, whisk together the flour, espresso powder, cocoa powder, salt, baking soda, and baking powder ensuring everything is well combined for consistent flavor and texture.
- Cream butter and sugars: In a separate bowl or stand mixer, beat the salted butter, brown sugar, and white sugar until light and fluffy, about 3-4 minutes, creating a smooth base for the batter.
- Add eggs and vanilla: Beat in the eggs one at a time and then the vanilla extract until fully incorporated, enhancing the moisture and flavor.
- Combine flour mixture: Add the dry mixture to the wet ingredients in thirds, beating after each addition just until combined to avoid overmixing which can toughen cookies.
- Scoop and shape dough: Use a 1 ½ tablespoon cookie scoop to portion dough, rolling each into balls. Place them on a parchment-lined baking sheet spaced 2 inches apart to allow room for spreading.
- Bake the cookies: Bake for 7-10 minutes until the edges are set and tops are puffy, about 8 minutes is ideal for soft centers and slightly crisp edges.
- Shape cookies (optional): Remove from oven and gently press with a biscuit or cookie cutter to achieve even, pretty circles. Let them cool for a few minutes on the sheet before transferring to a wire rack to cool completely.
- Prepare ganache: Chop the chocolate and place in a small bowl. Warm the heavy cream in 20-second increments in the microwave until hot but not boiling (approximately 40 seconds).
- Combine ganache: Pour the hot cream over the chocolate and let sit for a few minutes, then stir until smooth. If chocolate hasn’t fully melted, microwave an additional 5-10 seconds and stir again.
- Assemble cookies: Spoon about ¾ teaspoon of ganache onto each cooled cookie, spreading gently.
- Add toppings: Sprinkle mini rainbow candy-coated chips or rainbow sprinkles over the ganache while still wet to adhere.
- Set ganache: Allow cookies to set for about 1 hour at room temperature or enjoy immediately for a gooey chocolate experience.
Notes
- Using room temperature butter and eggs helps to achieve a smooth, well-mixed dough.
- Espresso powder enhances the chocolate flavor but can be omitted if sensitive to caffeine.
- Pressing the cookies into even circles after baking is optional but creates a uniform, professional look.
- Ganache can be stored separately in the refrigerator and reheated gently before use.
- The cookies are best enjoyed within 2-3 days but can be frozen for longer storage.
- If you prefer less saltiness, reduce sea salt to ¼ tsp especially when using salted butter.
