Preheat oven to 350 degrees. Line an 8x8 baking dish with parchment paper.
In a medium bowl, whisk together flour, salt, and baking powder. Set aside.
In a mixing bowl, cream together 1 cup butter and sugar until light and fluffy. About 2-3 minutes. Beat in the eggs, vanilla, and food coloring until well combined. Add the flour mixture until a soft dough forms. Dough will be very thick. Press into the bottom of a 9x13 inch baking dish.
Bake for 20 minutes until or until a toothpick entered into the center comes out clean.
Cool completely before frosting.
To make the cream cheese frosting, beat together the cream cheese and butter. Add the powdered sugar and vanilla. Beat together until smooth. Frost the top of the bars and sprinkle with your favorite sprinkles. Enjoy!
