No Chill Cosmic Brownie Cookies

Preheat the oven to 350° F and line 2 baking sheets with parchment paper.
In a large microwavable safe mixing bowl add the ½ cup butter and 6 oz chocolate. Microwave for 30 seconds at a time until fully melted, mixing in between. Cool for 5 minutes.
Add in the 1 egg, 2 yolks, 1 cup sugar, and 1 tsp of vanilla into the chocolate. Using a handheld mixer whip the mixture on high speed for 4 minutes until the mixture is frothy.
Next add in the 1 cup flour, 2 tbsp cup cocoa, ½ tsp kosher salt, and 1/4 tsp baking soda.
Using a spatula mix the dry ingredients into the batter until a thick uniform batter forms.
Using an ice cream scoop, scoop the cookie dough onto the parchment paper leaving 2 inches in between for the cookies to spread.
Bake for 12 minutes.
When the cookies come out of the oven, bang the sheet pan against the counter to flatten them. This will make them more fudgy. Use a larger cookie cutter to scoot the cookies in a circular motion to make them perfectly round.
Repeat the process if you only have one cookie sheet.
When the cookies are cooling, melt the 4 oz chocolate in a small microwave safe bowl.
Spoon the melted chocolate into the center of each cookie and immediately top with the rainbow chip sprinkles.
