Making the Cupcakes
Preheat oven to 350F (175C). Line a 12-cup muffin tin with cupcake liners.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
Stir in the finely ground freeze-dried strawberries.
Fill each cupcake liner about two-thirds full.
Bake for 18-20 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cupcakes cool in the muffin tin for 5 minutes, then transfer them to a wire rack to cool completely.
Making the Frosting
In a large bowl, beat the softened butter until smooth and creamy.
Gradually add the powdered sugar, beating until well combined.
Stir in the milk and vanilla extract.
Beat in the finely ground freeze-dried strawberries until the frosting is light and fluffy.
Assembling the Cupcakes
Once the cupcakes are completely cooled, frost them generously with the strawberry frosting.
Sprinkle the coarsely crushed freeze-dried strawberries over the frosting.
Optional Tips: For a stronger strawberry flavor, add a few drops of strawberry extract to the batter and/or frosting. To substitute all-purpose flour, a gluten-free 1:1 baking flour blend can be used.
