01 - Preheat the oven to 350°F. Line a 12-cup muffin tin with paper liners.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, cream the softened butter and sugar until light and fluffy, about 2–3 minutes.
04 - Beat in eggs, one at a time, then mix in vanilla.
05 - Alternately add the dry ingredients and milk to the butter mixture, beginning and ending with dry ingredients. Mix until just combined.
06 - Divide batter evenly among cupcake liners, filling each about 2/3 full.
07 - Bake for 16–18 minutes, or until a toothpick inserted into the center comes out clean. Cool in pan for 5 minutes, then transfer to a wire rack to cool completely.
08 - While cupcakes cool, toss diced strawberries with sugar and lemon juice. Let sit for 10 minutes to macerate.
09 - Once cupcakes are cool, use a paring knife or cupcake corer to remove a small cone from the center of each cupcake.
10 - Fill each cupcake with about 1 tablespoon of the macerated strawberries.
11 - In a chilled bowl, whip heavy cream, powdered sugar, and vanilla until stiff peaks form.
12 - Pipe or dollop whipped cream onto each cupcake. Garnish with a halved strawberry, if desired.
