Lemon Cupcakes With Lemon Buttercream Frosting

by Alli

Lemon Cupcakes are tender, slightly tart, and a whole lot delicious. The lemon buttercream frosting is creamy and is the perfect topping for these cupcakes.

I love all things citrus. Lately, I’ve baked lemon bread and key lime loaf. The grandkids love citrus flavored desserts just as much as I do. 

I always make a dessert or two for our Sunday family dinners. These lemon cupcakes are popular because they taste so good. Plus, it’s easy for me. I don’t have to slice, plate, etc. I just pass these babies out. 

Note: This recipe makes approximately 12 cupcakes. I always have a little batter leftover. If you’re a lick-the-bowl type of person, you’re in for a treat.

If you’re planning a picnic or barbeque, cupcakes are the way to go and these lemon cupcakes won’t disappoint. 

Ingredients for Lemon Cupcakes 

Sour cream is my secret ingredient in these lemon cupcakes. Sour cream gives more flavor and moisture to cupcakes and I do love a tender cupcake. 

For this recipe, you’ll need:

  • Granulated sugar
  • Unsalted butter, softened
  • Large eggs
  • Vanilla extract
  • All-purpose flour
  • Baking powder
  • Baking soda
  • Lemon zest (from 2 medium lemons)
  • Sour cream
  • Lemon juice
  • Milk
  • Lemon juice, lemon zest, and powdered sugar for the frosting

To frost these cupcakes with a buttercream swirl, I used a pastry bag with a Wilton 2D Large Drop Flower Piping Tip. When frosting cupcakes, remember to keep the pastry bag straight up. I start in the middle and work my way out and then back in.

Tips for Making Great Cupcakes

  • Always use quality ingredients.
  • Bring eggs and butter to room temperature.
  • Don’t overmix the batter.
  • Divide the cupcake batter evenly between the muffin tins. (I use this cookie dough scoop.)
  • Preheat the oven.
  • Don’t let the cupcakes stay in the tins to cool. Let them cool for 5 minutes in the pan and then transfer to a wire rack to cool completely.
