The Fluffiest Lemon Cupcakes With Creamy Lemon Frosting Recipe

I can’t get enough of these lemon cupcakes, with their tender crumb, bright citrus flavor, and dreamy creamy frosting. One bite and you’ll see why they disappear so fast.

I’m obsessed with these lemon cupcakes because they hit that sweet spot between bright, soft, and totally irresistible. I love how the crumb stays light and fluffy, while the creamy lemon frosting brings that tangy little punch I keep going back for.

Fresh lemon juice and lemon zest make every bite taste bold, not flat or fake. And the frosting?

Silky, citrusy, and dangerously spoon-worthy. I adore desserts that feel fun without being fussy, and these cupcakes do exactly that.

But honestly, it’s the first bite that gets me every time. Soft cake, sunny flavor, big lemon energy.

No notes from me.

How to Make this

1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with liners.

2. Whisk together 1 1/2 cups (190 g) all purpose flour, 1 cup (200 g) granulated sugar, 2 teaspoons baking powder, and 1/2 teaspoon fine salt in a large bowl.

3. In a separate bowl, beat 2 large room temperature eggs lightly, then whisk in 1/2 cup (115 g) melted and cooled unsalted butter, 1/2 cup (120 g) sour cream or plain Greek yogurt, 1/2 cup (120 ml) whole milk, 1/4 cup (60 ml) fresh lemon juice, zest of 2 lemons, and 1 teaspoon pure vanilla extract until smooth.

4. Pour the wet ingredients into the dry ingredients and stir gently until just combined; avoid overmixing. Batter will be slightly thick and speckled with lemon zest.

5. Divide batter evenly among the 12 liners, filling each about two thirds full, and bake for 18 to 22 minutes or until a toothpick inserted in the center comes out clean.

6. Cool cupcakes in the tin for 5 minutes, then transfer to a wire rack to cool completely before frosting.

7. For the frosting, beat 1 cup (230 g) room temperature unsalted butter until creamy. Gradually add 3 to 3 1/2 cups (360 to 420 g) sifted powdered sugar, 2 to 3 tablespoons fresh lemon juice, 1 tablespoon lemon zest, and 1/4 teaspoon fine salt, beating until smooth and fluffy. Start with 3 cups powdered sugar and add more if you prefer a stiffer frosting.

8. If the frosting is too thick, thin with 1 to 2 tablespoons heavy cream or milk until spreadable. Add a drop of yellow gel food coloring if you want a brighter color and mix until uniform.

9. Pipe or spread the lemon frosting onto completely cooled cupcakes. For a cleaner look, chill the frosting briefly if it softens while piping.

10. Garnish with additional lemon zest or a thin lemon slice if desired, then store cupcakes in an airtight container at room temperature for up to 2 days or refrigerate up to 5 days.

The Fluffiest Lemon Cupcakes With Creamy Lemon Frosting Recipe Substitutions and Variations

• All purpose flour: substitute cake flour for a lighter crumb. Use 1 1/3 cups cake flour for every 1 1/2 cups all purpose and reduce mixing slightly to avoid overworking.
• Sour cream or plain Greek yogurt: substitute buttermilk. Use 1/2 cup buttermilk and reduce the milk by 2 tablespoons to keep batter consistency.
• Unsalted butter (batter or frosting): substitute neutral vegetable oil in the batter for moistness. Use 2/3 the amount by volume (for 1/2 cup butter use 1/3 cup plus 1 tablespoon oil). For frosting, use 8 ounces cream cheese in place of 1 cup butter for a tangy, slightly softer frosting and chill briefly before piping.
• Powdered sugar: substitute sifted icing sugar or confectioners sugar 1:1. If using a less-refined powdered sugar, taste and add extra sifted sugar to reach desired sweetness and structure.

Pro Tips

1. Bring everything to room temperature before you start. Warm eggs, milk and sour cream blend more evenly and help the batter rise without overmixing, so your cupcakes stay tender.

2. Zest the lemons first, then juice them. Zesting directly into the bowl keeps the bright oils, and if you zest after juicing you may lose some flavor. Use a microplane and avoid the bitter white pith.

3. Fold gently and stop when you see no dry streaks. Overmixing develops gluten and makes cupcakes dense. A few small lumps are fine; they will smooth out as the cupcakes bake.

4. For frosting texture control, start with the lower amount of powdered sugar and add lemon juice little by little. If the frosting gets too soft while piping, chill it 10 to 15 minutes to firm up, or thin it with cream one teaspoon at a time until you reach the desired consistency.
