04 - Add eggs one at a time, mixing thoroughly after each addition. Blend in vanilla extract.
05 - Alternately add flour mixture and milk in three portions, beginning and ending with flour. Mix only until just combined to avoid overmixing.
06 - Transfer batter to prepared pan, smoothing the surface evenly with a spatula.
07 - Bake for 28 to 32 minutes or until a toothpick inserted in the center emerges clean.
08 - Let cake rest in pan for 10 minutes before turning out onto a wire rack to cool completely.
09 - Beat butter until creamy. Gradually incorporate powdered sugar, alternating with milk, until smooth and fluffy. Add vanilla extract.
10 - Divide buttercream into separate bowls. Blend food coloring into portions for flowers and leaves as desired.
11 - Spread an even layer of untinted buttercream over the cooled cake, covering the surface.
12 - Fill piping bags fitted with flower, leaf, and round tips. Pipe colored buttercream into decorative flowers and leaves along edges and corners.
13 - Pipe a cross or First Communion text using a small round tip, if desired.
