Instructions
- Preheat the oven to 350°F. Spray a 9×13-inch baking dish with baking spray and set it aside.

- Scrape down the sides of the bowl and stir in the sprinkles. Pour the batter into the baking dish and smooth out the top.
- Bake for 35-42 minutes until a toothpick inserted into the center comes out clean. Place on a wire rack to cool completely.
- While the cake is cooling, make the frosting by placing the butter into a large bowl with an electric hand mixer and whip until smooth.
- Slowly add the powdered sugar 1 cup at a time until incorporated. Add the salt, milk, and vanilla, stir until combined, then whip on medium-high speed until light and fluffy for 3 minutes.
