Amazing Lemon Cupcakes & Lemon Buttercream Frosting

I whipped up three different batches of new cupcakes for my Zimi's Birthday, and of all the cupcakes my kids decided this Lemon cupcake was the BEST one. It is absolutely delicious! Not to mention the Lemon Buttercream Frosting-- your in for a real treat!!


3 1/2 cups of all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1 cup butter, room temperature
1 1/2 cups sugar
2 teaspoons vanilla extract
3 eggs
16 oz sour cream
2 teaspoons fresh lemon zest


Preheat oven to 350 degrees. Line muffin tins with paper cupcake liners; set aside. In a medium bowl combine flour, baking powder, baking soda, and salt; set aside.

In an electric mixer fitted with paddle attachment beat butter and sugar until pale and fluffy. Scrape down sides of bowl. Beat in eggs one at a time, until incorporated. Scape down sides of bowl, and stir in vanilla. Add flour mixture and sour cream alternately; flour in three batches and sour cream in two batches, starting and ending with flour. Mix on slow speed, just until combine. Stir in lemon zest.

Spoon batter into prepared muffin tins, filling each 3/4 full. Bake in preheated oven for about 18-20 minutes. Cool completely then remove from muffin tin.

  1. Yummy! I can't wait to try this one. I made your raspberry cream filled cupcakes and they were a hit. Thanks for all the great recipes.


  2. Yayy!! I love the raspberry ream cupcakes too! I'm glad they were a hit for you.

  3. How would you convert this into a cake? Tony hates cupcakes (it takes "too long" to unwrap them -- dont ask me, he's got issues) but this sounds de-lish!
