Ingredients
Method
- Stir the cornstarch and warm water together in a small bowl until smooth and thick.
- Place the strawberries and sugar in a small saucepan and cook over medium heat, stirring and gently crushing some of the fruit as it warms.
- Bring the mixture to a gentle simmer, then pour in the cornstarch mixture and keep stirring while it cooks for about five minutes until thickened.
- Take the pan off the heat, mix in the lemon zest, and let the filling cool completely before using.
- Set the oven to 350°F (177°C) and line a muffin pan with cupcake liners, preparing extra liners for a second batch if needed.
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined.
- In another bowl, whisk the melted butter and sugar together, then blend in the egg whites, sour cream, milk, and vanilla until smooth.
- Pour the wet mixture into the dry ingredients and whisk just until a creamy batter forms with only a few small lumps.
- Spoon the batter into the liners, filling each about two-thirds full to leave room for rising.
- Bake the cupcakes for 20 to 22 minutes, until a toothpick inserted in the center comes out clean.
- Let the cupcakes rest in the pan for ten minutes, then move them to a rack to cool completely.
- Set aside half a cup of the strawberry filling, then cut a small circle from the center of each cooled cupcake to create a pocket.
- Spoon some of the strawberry filling into each opening, trim the cut-out cake piece, and place it back on top to seal. assemble
- Whip the heavy cream, sugar, and vanilla on medium-high speed until medium peaks form, about three to four minutes.
- Gently fold the reserved strawberry filling into the whipped cream until streaked and fluffy.
- Spread or pipe the strawberry cream over the filled cupcakes, piling it high if you like.
- Decorate with strawberry slices or mint if desired, then refrigerate until ready to serve.

Notes
These cupcakes taste like a picnic in dessert form—soft cake, jammy berries, and a fluffy crown of cream. They’re the kind of treat that disappears fast and gets everyone asking for the recipe.
