Preheat the oven to 350°F and line a 9x13 inch pan with parchment paper.
Combine the butter and white chocolate chips and melt in the microwave 30 seconds at a time and mix until melted.
Mix in sugar until combined, mix in eggs, vanilla, then flour, salt, and sprinkles.
Spread mixture into pan, garnish the top with additional sprinkles and bake for 30 minutes.
Tip: cover with aluminum foil 15 minutes in to baking to prevent over-browning on the edges of brownies. Insert a toothpick into the center of the brownies after 30 minutes. If it comes out clean, the brownies are done, if not cook additionally until done.
