Preheat oven to 350°F and line a muffin tin with cupcake liners.
In a bowl, whisk flour, baking powder, and salt. Set aside.
Cream butter and sugar together until light and fluffy.
Add eggs one at a time, then stir in vanilla.
Add dry ingredients to wet ingredients in batches, alternating with milk. Don’t overmix.
Spoon batter into cupcake liners, filling each about 2/3 full.
Bake for 16–18 minutes or until a toothpick comes out clean. Cool completely.
Meanwhile, toss chopped strawberries with sugar and let sit for 15 minutes.
Cut a small cone from the top center of each cupcake and fill with macerated strawberries.
Top each cupcake with whipped cream and an extra strawberry slice if you’re feeling fancy.
