Preheat the oven to 350 degrees.
Line a 9x13 inch baking dish with parchment paper and spray with non-stick spray.
In a large mixing bowl combine the granulated sugar, brown sugar, vanilla, salt, whole eggs and yolks. Mix with hand mixer or stand mixer until combined.
In a microwave safe bowl melt the butter and chocolate chips together in 30 second intervals until melted and smooth.
Add the vegetable oil to the bowl with melted chocolate and whisk until combined.
Pour the chocolate mixture into the sugar mixture and mix until fully combined.
Gently fold in the flour and cocoa to brownie batter until just combined.
Pour the brownie batter into the prepared pan and bake until a toothpick inserted in the center comes out clean about 35 minutes.
Remove from the oven and set aside to cool.
Once cooled, cover the brownies, and let sit overnight to set up.
The next day use a small plastic star cookie cutter to cut out stars.
Set the brownie bites on a cookie sheet lined with parchment paper.
In 2 microwave safe bowls place your red chocolate in one and white chocolate in the other.
Melt each bowl of chocolate in the microwave in 30 second intervals until all melted and smooth.
Using a spoon or fork drizzle each color chocolate over each brownie bite and immediately top with sprinkles.
Place the pan in the refrigerator for 15-20 minutes to let the chocolate set.
