Preheat oven to 350°F (175°C) and line a cupcake pan with liners.

In a bowl, mix together the flour, baking powder, and salt.

In a separate bowl, cream together the softened butter and sugar until light and fluffy.

Add eggs one at a time, mixing well after each addition. Then stir in the vanilla extract.

Gradually add the dry ingredients to the wet ingredients, alternating with the milk, and mix until just combined.

Fill cupcake liners about two-thirds full with batter.

Bake in preheated oven for 20 minutes or until a toothpick inserted in the center comes out clean. Let cool.

For frosting, beat together softened butter and powdered sugar until smooth. Mix in heavy cream and vanilla extract until well combined.

Frost the cooled cupcakes and top with colorful sprinkles and edible flowers if using.
