Ingredients, Brownies:
1 cup All-purpose flour
ΒΎ cup Unsweetened cocoa powder
Β½ tsp Salt
Β½ cup + 2 tbsp Vegetable oil
1 Β½ cups Brown sugar
2 Whole eggs + 2 Egg yolks
2 tbsp Light corn syrup
1 tbsp + 1 tsp Vanilla extract
Ingredients, Ganache:
1 β
cups Semi-sweet chocolate chips
3 oz Heavy cream
1 tbsp Vanilla extract
2 tsp Corn syrup
1 pinch Salt
Directions:
π Preheat oven to 350F and line a metal 9 x 13β baking pan with parchment, lightly grease with cooking spray
π Sift flour, cocoa powder, and salt into a large bowl and whisk to combine
π In a separate medium bowl, whisk together the oil, brown sugar, eggs and yolks, corn syrup, and vanilla extract until well combined
π Pour wet ingredient mixture into the dry ingredients and stir until just combined and no dry ingredient streaks or clumps remain then spread batter into pan
π Bake for 15-20 minutes (or until a toothpick inserted into the center comes out clean) set aside
π Make ganache: Stir all ingredients together in a medium sized microwave-safe bowl, microwave for 30 seconds, and stir, then microwave for an additional 15 seconds and stir again (allow the residual heat to continue to melt the chocolate as much as possible)
π While ganache is still warm (microwave for several seconds to warm back up if needed), spread in an even layer over the brownies and immediately sprinkle on Wilton Rainbow Chip Crunch Sprinkles
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.
