# How-To Steps:
01 - Preheat oven to 350°F. Grease and line a 12x18-inch sheet pan with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
03 - In a large bowl, beat butter and sugar together until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
05 - Add half the dry ingredients to the wet mixture and mix on low speed. Pour in half the milk and mix gently. Repeat with remaining dry ingredients and milk, mixing just until combined.
06 - Pour the batter into the prepared pan and spread evenly.
07 - Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.
08 - Let the cake cool completely in the pan on a wire rack.
09 - Beat butter until creamy, about 2 minutes. Gradually add powdered sugar, mixing on low speed. Add vanilla, milk, and salt. Beat on high for 2 to 3 minutes until fluffy. Add food coloring if desired.
10 - Spread buttercream evenly over the cooled cake. Decorate with graduation-themed sprinkles or edible decorations.
11 - Slice and serve.
