01 - Preheat the oven to 350°F. Grease a 12-cup muffin tin or line with paper cases.
02 - In a bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat butter and sugar until light and fluffy.
04 - Add eggs, one at a time, beating well after each. Mix in vanilla extract.
05 - Add half the flour mixture and mix gently. Add milk, then the remaining flour mixture, mixing just until combined.
06 - Divide the batter evenly among the muffin cups, filling about 2/3 full.
07 - Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
08 - Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
09 - Mix powdered sugar with milk until smooth and thick but pourable. Divide into separate bowls and tint each with a different pastel food color.
10 - Spoon or drizzle colored icing over each cooled cake. Decorate with mini eggs, edible flowers, or sprinkles as desired.
11 - Allow icing to set before serving.
