Ingredients

  • Ensures a soft, sturdy base that holds up to the generous layer of buttercream; ever since switching to room temperature flour, my cakes have baked up perfectly even.
  • Sweetens the cake and also helps it stay moist; I always make sure to cream it thoroughly with the butter for a lighter crumb.
  • Both cake and frosting rely on it; letting it sit on the counter for an hour means no lumps during mixing.
  • Brings richness and structure; I learned that cold milk can cause curdling (not ideal before a party).
  • Help bind everything together and give a tender rise; warming them in a bowl of warm water saves time when you forget.
  • Delivers warm aroma and classic flavor; splurge on pure vanilla for graduation-worthy results.
  • Guarantees a fluffy rise; always double-check its freshness for bigger occasions.
  • Just half a teaspoon sharpens all the sweetness; don't skip it, even if tempted.
  • For the buttercream; sifting prevents gritty frosting and pipes smoother roses.
  • Gives bold hues without watering down your frosting; I mix colors for unique shades every time.
  • Add a touch of graduation sparkle or elegance; guests always notice these tiny details.
  • Perfect for diplomas and ribbons; fondant is easier to shape but chocolate tastes richer.

Instructions

Step 01

Prepare Cake Pan: Preheat oven to 350°F. Grease and line a 12x18-inch sheet cake pan with parchment paper.

Step 02

Cream Butter and Sugar: In a large bowl, beat unsalted butter and granulated sugar until light and fluffy, about 3 minutes.

Step 03

Add Eggs and Vanilla: Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.

Step 04

Combine Dry Ingredients: In a separate bowl, whisk together all-purpose flour, baking powder, and salt.

Step 05

Mix Batter: Add flour mixture to butter mixture in three additions, alternating with milk, starting and ending with flour mixture. Mix until just combined.

Step 06

Bake Cake: Pour batter into prepared pan. Smooth the top. Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.

Step 07

Cool Cake: Allow cake to cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.

Step 08

Prepare Buttercream: Beat unsalted butter for buttercream until creamy. Gradually add sifted powdered sugar, vanilla, and milk, mixing until fluffy. Adjust consistency as needed.

Color Buttercream: Divide buttercream into bowls. Tint portions pink, red, or yellow for roses, green for leaves, and leave some white for main coating.

Step 10

Frost Cake: Coat the cooled cake with a smooth layer of white buttercream using an offset spatula.

Step 11

Pipe Roses and Leaves: Using piping bags fitted with rose and leaf tips, pipe buttercream roses and green leaves in desired colors.
