Strawberry Cupcake Recipe bursts with fresh strawberry flavor. These moist fluffy cupcakes are topped with a luscious homemade strawberry buttercream frosting.
Make the strawberry purée by combining all ingredients in a saucepan. Bring to a boil and then simmer over medium-low heat for 15 mins, stirring frequently. Smash the berries. Set aside to cool.
Cream the butter and sugar together until light and fluffy, about 4-5 minutes with an electric mixer. Add egg whites and vanilla to the butter mixture.
Beat until well incorporated. Scrape down the sides of the bowl. In a large bowl, combine the dry ingredients, flour, baking powder, baking soda and salt.
Alternate between adding the dry ingredients and the milk slowly until both are incorporated into the butter mixture. Finally add in lemon zest and strawberry puree. Mix until combined.
