- 4 cups powdered sugar
- 1/8 tsp. salt
- 4 tbsp. fresh lemon juice
- 2 tbsp. milk
Instructions
Lemon Cupcakes
- Preheat oven to 350° F. Prepare cupcake tin with paper liners. Lightly spray the bottoms of the cupcakes with cooking spray.
- Cream butter and sugar together in the bowl of your mixer (or in a large mixing bowl using a hand-held beater) until light and fluffy. Add beaten eggs and beat well for 2-3 minutes, until light yellow in color. Stir in vanilla and lemon juice until blended.
- Sift dries (cake flour, baking soda and salt) in a separate bowl.
- Stir flour into batter alternately with milk, beginning and ending with dry ingredients.
- Distribute batter evenly among the 12 cupcakes. Bake for 15-18 minutes, or until the center springs back when you gently touch it with your thumb.
- Remove from oven and cool completely.
Lemon Curd
- Whisk eggs and sugar together in a saucepan or in the top of a double boiler. Add lemon juice, lemon zest and salt.
- Heat over medium heat, stirring constantly with a wire whisk, until mixture thickens so it will coat the back of a spoon. Remove from heat and stir in the butter. Set aside until completely cool. If making ahead of time, cover the lemon curd with plastic wrap and refrigerate until ready to use.
Fresh Lemon Juice Buttercream Frosting
- In a large bowl, cream together butter and salt until light and fluffy. Add 1 cup of the powdered sugar and beat into the butter. Add 1 tablespoon of the lemon juice and continue to beat. Continue this process, alternating powdered sugar and lemon juice. Beat until creamy and smooth. If you need a little more liquid, add a little bit of milk at a time. If the frosting is too runny, add more powdered sugar, a little bit at a time, until you arrive at a good spreading consistency.
Assembling Cupcakes
- Using a spoon or apple corer, create a cavity in the center of the cupcake. Reserve the cake “corks” to plug the top of the opening after you fill them with the lemon curd.
- Using a pastry bag or small spoon, fill the cavities in each cupcake with the lemon curd. Replace a small part of the “cork” you removed on top of the curd filling.
- Now using a pastry bag with a large open star tip (#824), create a beautiful swirl of frosting on top of each cupcake. Garnish with a half slice of lemon.
