- ½ cup + 2 tbsp Vegetable oil
- 1 ½ cups Brown sugar
- 2 Whole eggs + 2 Egg yolks
- 2 tbsp Light corn syrup

Assembly
Instructions
Brownies
- Preheat oven to 350F and line a metal 9 x 13” baking pan with parchment. Lightly grease with cooking spray.
- Sift flour, cocoa powder, and salt into a large bowl and whisk to combine.
- In a separate medium bowl, whisk together the oil, brown sugar, eggs and yolks, corn syrup, and vanilla extract until well combined.
- Pour wet ingredient mixture into the dry ingredients and stir until just combined and no dry ingredient streaks or clumps remain.
- Spread batter into the prepared pan in an even layer.
- Bake for 15-20 minutes, or until a toothpick inserted into the center comes out clean (just a crumb or two stuck to the toothpick is ok). Leave brownies in the pan and set aside until ready to top with ganache.
Ganache
- Stir all ingredients together in a medium sized microwave-safe bowl.
- Microwave for 30 seconds, and stir.
- Microwave for an additional 15 seconds and stir again. Allow the residual heat to continue to melt the chocolate as much as possible.
- If there are still small solid pieces of chocolate remaining, microwave in several second bursts and then stir until ganache is smooth.
Assembly
- While ganache is still warm (microwave for several seconds to warm back up if needed), spread in an even layer over the brownies. (Brownies can still be warm during this step)
- Immediately sprinkle on Wilton Rainbow Chip Crunch Sprinkles. Enjoy!
- Optional but recommended: Allow brownies to chill in freezer for 1 hour, or the fridge for a few hours to fully set the ganache and firm up the brownies before cutting.
Notes
Tip: For super clean cuts, clean your knife off in between each cut. Cut brownies into 16 2” x 3” pieces to replicate a similar size to the original cosmic brownie. Bonus step, drag a knife through the ganache in the middle of the brownie bars to create the indent line from the original look as well.
