Preheat oven to 350 degrees and grease an 8 x 8 pan, lining with parchment if desired.
Melt the butter in a large bowl using the microwave. Mix in the sugars until well blended. Add in the eggs, corn syrup and vanilla extract, mixing until combined.
Sift together the flour, cocoa powder, baking powder and salt. Add to the egg mixture, along with mini chocolate chips, and blend until just combined. The mixture will be very thick.
Spread into prepared pan and bake at 350 degrees for 30-32 minutes or until just a few crumbs cling to a toothpick upon testing. Remove from oven and cool completely on wire rack.
To make the ganache, heat heavy cream until just steaming (about a minute if you use the microwave) and pour over chocolate chips. Let stand for five minutes and stir until chocolate is melted. Pour over cooled brownies and spread. Top with sprinkles.
