Instructions

1. 1 Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Lightly coat a 9x13-inch baking pan with baking spray; set aside.
2. 2 Whisk together cake mix, buttermilk, oil, eggs, and food coloring in a medium bowl until fully combined and no dry streaks remain. Transfer to the prepared baking pan and spread in an even layer.
3. 3 Bake in the preheated oven until a wooden pick inserted in center comes out clean, 20 to 25 minutes. Let cool completely in pan on a wire rack, about 1 hour.
4. 4 Beat cream cheese and butter with an electric mixer on medium speed until light and fluffy, 1 to 2 minutes.
5. 5 Gradually beat in powdered sugar with mixer on low speed, until smooth and fully combined, stopping to scrape down sides of bowl as needed, about 3 minutes. Add vanilla and salt and beat until just combined.
6. 6 Using an offset spatula, spread cream cheese frosting evenly over the top of the cooled cake. Garnish with sprinkles, if desired.
7. 7 Cut into squares and serve.
