Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
In another bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk, and mix until just combined.
Divide the batter evenly between the prepared pans.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Once cooled, frost the cake with buttercream frosting, using pastel food coloring to achieve desired hues.
Decorate with edible sugar flowers for a beautiful spring presentation.
