Not only are these cookies beautiful, but they are easy too; Cosmic Brownie Cookies are a hit with the whole family. Using boxed brownie mix, they come together in no time!
Line a sheet pan with parchment paper and set it aside. Mix together the brown mix, oil, and egg until combined in a large bowl. The mixture will be thick.
Taking about 2 tablespoons of the brownie cookie dough and roll it into a ball with your hands. Place the cookie dough ball on the sheet pan, and repeat with the remaining dough.
Place the sheet tray with the cookie dough balls into the refrigerator for 30 minutes to chill.
Preheat the oven to 350°F. Line sheet pans with parchment paper.
Place the cookie dough balls about 2-3 inches apart on the sheet pans. Bake for 9-11 minutes or until the tops of the cookies do no longer appear glossy. Be careful not to overbake.
Let the cookies cool for 10 minutes on the sheet pans and then transfer them to a wire rack to completely cool.
Make the chocolate ganache when the cookies have completely cooled. Finely chop the baking bar. Place it into a heatproof bowl.
Pour the heavy cream into a small saucepot and bring it just to a simmer, as soon as you see the first bubbles, it’s ready. Pour the hot cream over the chopped chocolate. Let it sit for 5 minutes and then whisk it until smooth.
One by one, take the cookies and dip the tops into the ganache. Place it back on the wire rack ganache side up and immediately top it with the rainbow candy chip sprinkles. Repeat with the remaining cookies.
