Cupcakes are the perfect treat to combine the fresh, bright flavors of strawberry and lemon. These strawberry lemonade cupcakes are moist, perfectly fluffy, and bursting with fresh fruit flavors. The cupcakes have a delicious slightly tangy lemon flavor.

To make this fabulous dessert, we start with moist lemon cupcakes. The lemon cupcakes are made with sour cream so they’re perfectly moist. Then we’re using just the egg whites and adding a little cornstarch to keep the batter light. Fresh lemon zest & freshly squeezed lemon juice give the lemon flavor.


  • 1 and 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup granulated sugar
  • 3/4 cup milk
  • 1/2 cup sour cream
  • 1/4 cup vegetable oil
  • 1/3 cup strawberry jam
  • 1 egg
  • 1 teaspoon vanilla
  • 1/8 teaspoon almond extract
  • Lemon Swiss Meringue Buttercream
  • 5 egg whites, room temperature
  • 1 and 1/4 cups sugar
  • 1/4 teaspoon salt
  • 1 and 1/2 cup (3 sticks) unsalted butter, room temperature
  • 7 Tablespoons lemon juice
  • 2 teaspoons vanilla extract
  • 1/4 teaspoon almond extract
  • Strawberries, for topping


  1. Preheat oven to 350ºF, and line a muffin pan with cupcake liners.
  2. In a large mixing bowl, whisk together the flour, baking soda, salt, and sugar until well blended. Add the milk, sour cream, oil, jam, egg, vanilla, and almond extract and stir until just combined.
  3. Pour batter into cupcake liners, filling 2/3 of the way. Bake in the oven for 16-18 minutes, or until a toothpick inserted in the center comes out clean.
  4. Allow cupcakes to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
  5. Make the Buttercream: In a heat-safe bowl, whisk the egg whites, sugar, and salt together. Remove bowl from mixer, then place over a pan of simmering water, not touching the water. Whisk until warm and sugar are dissolved, about 2-3 minutes.
  6. The mixture should feel completely smooth with no graininess when a bit is rubbed between two fingers. Remove from heat and chill in the freezer for 15-20 minutes, or until mixture is cool.
  7. Meanwhile, in the bowl of a stand mixer fitted with the paddle attachment, beat the butter on high until fluffy and lightened in color. Add about half of the cooled syrup and beat for one minute.
  8. Add the last half and continue beating until mixture is thick, yet fluffy. With the mixer on low, add the lemon juice, vanilla, and almond extract, and beat until smooth and fully incorporated.
  9. Frost or pipe buttercream onto cooled cupcakes, as desired. Top each cupcake with a fresh strawberry.
