08 - Allow cake to cool in the pan for 10 minutes, then invert onto a wire rack and cool completely to room temperature.
09 - Beat softened butter until creamy. Gradually add powdered sugar, alternating with milk, beating until smooth and fluffy. Mix in vanilla extract.
10 - Divide buttercream into separate bowls and tint portions with food coloring for flowers, leaves, and any additional decorative elements.
11 - Spread a generous layer of plain buttercream evenly over the cooled cake as the foundation layer.
