Preheat oven to 350 degrees
Grease an 8" x 8" baking pan and set aside.
Carefully melt white chocolate chips at 50% power in microwave, stirring often to make sure they don't burn. Once they are just about melted, stir in softened butter and remaining ingredients (except sprinkles) which you will want to fold in gently at the very end. Spread dough into pan and cover the top of the dough with the remaining sprinkles.
Bake for about 22 minutes or until the bars begin to turn golden around the edges of the pan.
The bars will be a bit gooey when you remove them from the oven, they will continue to set as they cool for 30 minutes to an hour.
Store in an airtight container.
