Perfect Lemon Cupcakes with Lemon Buttercream


  • Cake:
  • 1 package lemon cake mix
  • 1 cup sour cream
  • 3/4 cup water
  • 3/4 cup oil
  • 4 eggs
  • 1 small package lemon instant pudding
  • Lemon Buttercream Frosting:
  • 1 cup (2 sticks) butter, very soft
  • 68 cups powdered sugar
  • 1/2 cup fresh lemon juice
  • 1 teaspoon grated lemon zest
  • Berries, optional fro garnish


  1. Add of the the cake ingredients to a large mixing bowl. Mix with electric mixer on medium speed for about two minutes. Use a strong mixer, this batter is thick.
  2. For cupcakes, bake them at 350 degrees for 20 minutes (I was able to get 24 very full cupcakes from the recipe). For regular cake, pour into a greased 9×11 pan or two round pans. Bake at 350 degrees for 25-30 minutes. Don’t over bake or the cake will be too dry! The toothpick test works to check to see if they’re done. Allow to cool.
  3. The original recipe said that the cupcakes will fall after they come out of the oven, but this is normal and to just fill up the indentation with more frosting. I didn’t have this problem at all!
  4. For frosting, place the butter in a large mixing bowl. Add 4 cups of sugar, then the juice and the zest. Beat until smooth and creamy.
  5. Gradually add the remaining sugar, 1 cup at a time, until icing is thick enough to be of good spreading consistency (I added 6 cups total). Use and store at room temperature. (Don’t refrigerate and it will last in a covered container for about three days.)
  6. Frost cooled cupcakes with frosting. Garnish with berries, if desired right before serving.
