Instructions
**For the cookies:**
- In a stand mixer, blend melted butter, granulated sugar, light brown sugar, and vanilla extract for 1 minute on medium speed.
- Add eggs and mix on low until combined.
- Incorporate flour, corn starch, cocoa powder, baking soda, and salt, mixing on low until everything comes together.
- Using a medium-sized cookie dough scoop (about 2-2.5 tablespoons), form 20 even cookie balls on a parchment-lined baking sheet.
- Refrigerate for 30 minutes to enhance flavor and prevent spreading. Preheat the oven to 350°F.
- Space chilled cookie dough 2 inches apart on a parchment-lined sheet and bake for 9-10 minutes until edges are set.
- Cool on the baking sheet for 3 minutes, then transfer to a rack to cool completely.
**For the ganache:**
- While cookies cool, break chocolate into pieces and place in a heatproof bowl.
- Heat cream in a pot on the stove until simmering, then pour over the chocolate.
- Let it sit for 5 minutes, then add vanilla extract and whisk until smooth.
- Cool for 15-30 minutes until spreadable.
**Assembling:**
- Once cookies are completely cooled, spread 2-3 tablespoons of ganache on top, leaving a ¼-inch border.
- Sprinkle cosmic brownie sprinkles on top.
- Serve or refrigerate to set the ganache completely.
