Preheat oven to 350°F. Line a mini cupcake pan with mini paper liners. Combine the flour, baking powder, and salt in a small bowl. Mix and set aside.
1 1/4 cups all purpose flour, 1 1/4 teaspoons baking powder, 1/4 teaspoon salt
In the bowl of an electric mixer fitted with a paddle attachment, cream together the butter and sugar on medium high speed for 3 to 5 minutes, or until light and fluffy.
1/4 cup butter, 3/4 cup granulated sugar
Add the eggs one at a time, then the vanilla extract and strawberry powder.
2 eggs, 1 teaspoons vanilla extract, 1-2 tablespoons freeze dried strawberry powder
Turn the mixer to low and starting with the flour mixture, alternate adding the flour and milk to the bowl 1/3 at a time, until everything is just mixed, scraping down the sides of the bowl with a silicone spatula periodically. Be careful not to over mix.
1/4 cup whole milk
Fill the cupcake liners about 2/3rds of the way full.
Bake the cupcakes for 12-15 minutes. Check to see if they are fully done baking by inserting a toothpick into the middle of a mini cupcake to see if it comes out clean.
Let the cupcakes cool completely before topping with the icing.
