My lemon cupcakes are ready in under an hour, delivering refreshing citrus flavor, a moist, fluffy crumb, and perfectly silky Ermine Frosting.
- 1 large egg, at room temperature
- ¼ cup (2 oz/57 g) sour cream, at room temperature
- 2 tablespoons whole milk
- 2 tablespoons fresh lemon juice
- 1 tablespoon lemon zest
- 6 tablespoons (3 oz/85 g) butter, melted
- ¾ cup ( 3¾ oz/105 g) all-purpose flour
- ½ cup (4 oz/115 g) granulated sugar
- ¾ teaspoon baking powder
- ⅛ teaspoon baking soda
- ⅛ teaspoon salt
- 1 recipe Lemon Ermine Frosting
-
Preheat the oven to 350°F (180°C) and line a 12-cup cupcake pan with 9 paper liners. Set aside.
-
In a large bowl, whisk together the egg, sour cream, milk, lemon juice, zest and melted butter until combined.
-
In a separate bowl mix the flour, sugar, baking powder, baking soda, and salt. Mix the dry into the wet until just combined.
-
Divide the batter evenly among the prepared baking cups about ¾ of the way full.
-
Bake for 15 to 18 minutes, or until a toothpick inserted into the center comes out clean.
-
Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
-
When cooled, frost with Lemon Ermine Frosting or frosting of your choice!
-
Store in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 3 days.
- Zap your lemons first. My trick to getting the most juice out of a lemon is to microwave it for about 20 seconds to 1 minute, depending on how ripe your lemon is.
- Make more cupcakes! This recipe yields nine cupcakes, but you can easily double the recipe if you want more!
- Take ingredients out ahead of time. As always with cakes and cupcakes, make sure all of your ingredients are at room temperature for the best results!
- Double up on lemon flavor. Our Lemon Ermine Frosting is the ideal topper for these cupcakes. It's fluffy, full of bright flavor, and just sweet enough
- Opt for another topping. Our Best Ever Cream Cheese Frosting is also delicious on these cupcakes! Cupcakes frosted with Cream Cheese Frosting must stay refrigerated in an airtight container.
- Try this easy garnish. These cupcakes are so good that they don't need decoration, but you can easily fancy them up with the twists you see here. Simply take a very thin lemon round, make one cut from the edge of the slice to the center, and, holding the slice with two hands, gently twist it to make a spiral.
