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

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

In another bowl, beat together the softened butter, eggs, vanilla extract, and milk until smooth.

Combine the wet ingredients with the dry ingredients and mix until just combined.

Divide the batter evenly among the cupcake liners.

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

Allow the cupcakes to cool completely before frosting.

For the frosting, beat the softened unsalted butter until creamy.

Gradually add powdered sugar and mix until smooth. Add heavy cream and vanilla extract, and mix until well combined.

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