Perfect vanilla cake topped with creamy buttercream frosting and your favorite colored sprinkles is perfect for any birthday or special occasion.
Cake: Heat oven to 350°F. Spray a 13×9 inch cake pan with cooking spray; set aside.
In a large bowl combine your dry ingredients; flour, sugar, baking powder, and salt together. Add the eggs, oil, milk, and vanilla and mix with a mixer on medium/high speed for about 2-3 minutes or until smooth.
Pour the batter into the sprayed baking sheet. Place in center rack of oven and bake for 30-35 minutes or until the cake is lightly browned and toothpick comes out clear or when it springs back when pressed with a finger. Cool the cake on a wire rack while preparing the frosting.
Frosting: In a large bowl beat butter with mixer on medium speed until smooth. Add the powdered sugar 1/2 cup at a time, beating well after each addition. Add the vanilla, half and half (or milk) a tablespoon at a time and beat until smooth and fluffy. You might need to add a little more half and half or milk until you get the consistency you want. Only add a teaspoon at a time.
Once cake is completely cooled, spread the frosting on top of the cake with a frosting spatula or the back of a spoon. Decorate with your favorite colored sprinkles.
