# How-To Steps:
01 - Preheat oven to 350°F. Grease and line a 12x18-inch sheet cake pan with parchment paper.
02 - In a large mixing bowl, beat unsalted butter and granulated sugar with an electric mixer until light and fluffy, about 3 minutes.
03 - Add eggs one at a time, blending well after each addition. Stir in vanilla extract.
04 - In a separate bowl, whisk together all-purpose flour, baking powder, and salt.
05 - Gradually add the flour mixture to the butter mixture in three additions, alternating with whole milk. Begin and end with the flour mixture. Mix just until combined.
06 - Pour batter into the prepared pan and smooth the surface evenly.
07 - Bake for 28 to 32 minutes, or until a toothpick inserted into the center emerges clean.
08 - Cool in the pan for 10 minutes, then remove and transfer to a wire rack to cool completely before decorating.
09 - In a mixing bowl, beat unsalted butter until creamy. Gradually add powdered sugar, vanilla, and milk or cream, mixing until smooth and fluffy. Adjust consistency with additional milk or powdered sugar as necessary.
10 - Portion buttercream into separate bowls. Tint with gel food coloring to create desired shades for roses, leaves, and diploma accents. Reserve some white for base coating.
11 - Cover the entire cooled sheet cake with a smooth layer of white buttercream using an offset spatula.
12 - Using piping bags fitted with a rose tip, pipe buttercream roses in choice of colors. Pipe leaves with a leaf tip.
13 - Shape a diploma scroll from fondant or white chocolate and tie with a fondant ribbon. Position the diploma decoratively on the cake.
14 - Accent the cake with edible pearls and any additional decorative touches as desired.
