Preheat the oven to 350 degrees.
Prepare a 9"x13" baking dish with parchment paper and spray with nonstick cooking spray.
Note: You'll want to leave an inch or two of parchment paper over the edge on each end so that you can lift the brownies out of the pan later on.
In a large mixing bowl mix melted butter, sugar, and brown sugar. Mix until creamed and smooth. This can be done by hand (with a Danish dough hook) or with an electric mixer on low speed until just combined.
Add eggs and vanilla. Mix.
Add flour, cocoa powder, and salt. Mix.
Pour brownie batter into the prepared baking dish. Spread with a rubber spatula.
Bake brownies for 20-22 minutes. Brownies may seem undercooked, but that is fine. They will continue to bake in the pan while it cools.
Let brownies cool for 20 minutes (they'll still be warm). While they sit, make the ganache.
Combine ganache ingredients and melt on the stovetop over med-low heat OR in the microwave in 15-20 second intervals, stirring in between each interval until melted and smooth.
Pour ganache over warm brownies and spread until smooth. Sprinkle with rainbow chip sprinkles.
Let brownies sit for 1 hour at room temperature then chill for 1-2 hours in the refrigerator.
Lift the brownies from the pan (using the parchment paper), while chilled, and set them on a cutting board. Use a sharp knife to trim the edges and slice them into rectangles.

Store brownies at room temperature in an airtight container or cover them with plastic.
