Make Strawberry Lemonade Cupcakes Recipe: bright lemon cupcakes studded with fresh strawberries and topped with lemon buttercream.
Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with white paper cupcake liners, pressing each liner neatly into the cups so they sit flat and ready; set the lined tin to one side on the painted pine wood surface while you work through the batter.
In a medium bowl whisk the all-purpose flour with the baking powder and salt until the mixture looks uniform and airy; this distributes the leavening so each cupcake rises evenly and removes lumps for a tender crumb.
In a large bowl cream the softened unsalted butter with the granulated sugar until the mixture becomes pale, light, and fluffy — you should be able to see tiny air pockets and a slight ribbon when the beater is lifted.
Beat in the eggs one at a time, mixing well after each addition so the batter regains its smooth texture and emulsifies, scraping down the sides as needed to keep everything fully combined.
Add the lemon zest, the tablespoon of fresh lemon juice, and the vanilla extract into the creamed mixture and stir briefly to release bright citrus oils and aromatic vanilla into the batter.
Gradually add the dry flour mixture to the wet ingredients while alternating with the milk, beginning and ending with the flour mixture; fold and mix until just combined so the batter remains tender and not overworked.
Gently fold the diced fresh strawberries into the batter with a spatula so you retain distinct soft pink fruit pieces suspended in the pale batter rather than pulverizing them.
Divide the batter evenly among the lined cups, filling each about two-thirds full so there's room to rise; give the tin a gentle tap to settle the batter and smooth tops as needed.

Bake the cupcakes until a toothpick inserted into a center cupcake comes out clean, about 18–22 minutes; watch for a faint golden top and slight spring when touched gently.
Remove the cupcakes from the (unseen) oven and transfer the tin briefly to the painted surface, then lift the cupcakes out onto a wire cooling rack to cool completely so the frosting won’t melt when applied.
Beat the softened unsalted butter until creamy and smooth in a clean bowl, creating a satiny base for the lemon buttercream that will hold its swirl when piped.
Gradually add the powdered sugar to the creamed butter, mixing after each addition to keep the frosting light and to avoid a gritty texture; scrape the bowl to ensure even incorporation.
Add the fresh lemon juice, lemon zest, vanilla extract, and a pinch of salt to the frosting and beat until completely smooth and fragrant, tasting for a bright but balanced lemon flavor.
Add heavy cream one tablespoon at a time until the buttercream reaches a fluffy, pipeable consistency—soft enough to swirl but firm enough to hold peaks.
Frost the completely cooled cupcakes using a piping bag fitted with your favorite tip or a small offset spatula, creating tall, airy swirls of lemon buttercream that show fine texture and peak detail.
Top each frosted cupcake with a halved fresh strawberry and a thin lemon slice for a bright, fresh garnish; arrange the cupcakes on a silver wire cooling rack on the painted pine surface for serving.
