# How To Make It:
01 - Preheat oven to 350°F (175°C). Grease and line a 12×18 inch sheet cake pan with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, cream butter and sugar together until light and fluffy, about 3–4 minutes.
04 - Beat in eggs, one at a time, mixing well after each addition. Stir in vanilla extract.
05 - Add the flour mixture in three parts, alternating with the milk, beginning and ending with flour. Mix until just combined.
06 - Pour batter into prepared pan, smoothing the top. Bake for 28–32 minutes, or until a toothpick comes out clean. Cool completely in the pan on a wire rack.
07 - For the Buttercream: In a large bowl, beat butter until creamy. Gradually add powdered sugar, beating well. Mix in vanilla, salt, and add cream 1 Tbsp at a time until desired consistency is reached.
08 - Tint the majority of buttercream with sage green gel food coloring. Reserve ½ cup for gold accents.
09 - Spread the sage green buttercream evenly over cooled cake.
10 - To make gold accents, mix edible gold luster dust with a few drops of clear vanilla or vodka. Using a food-safe brush, paint gold over piped accents or details made with the reserved buttercream. Alternatively, mix dust with buttercream for a marbled gold effect.
11 - Decorate as desired with graduation symbols, gold sprinkles, or celebratory piping.
