Lemon cupcakes are one of my absolute favorite cupcake flavors. I’m a huge fan of lemon desserts as it is. But when you take a lemon cupcake, fill it with lemon curd, and top it with lemon buttercream, you have the ultimate spring dessert.

Why this Lemon Cupcakes recipe works

How to make lemon cupcakes with lemon curd filling
There’s nothing fancy about the cupcake batter. It’s a simple mix of creamed butter, sugar, eggs, lemon zest, lemon juice, milk, and flour. A little salt and baking powder are also added. The batter whips up into a silky, creamy texture that smells of fresh lemon.
It’s quite amazing and I know you will love it after the first bite.
There’s just enough batter for 12 muffin cups so you can simply divide the batter evenly among the cups. They’ll end up being about 2/3 of the way full.
After the cupcakes bake, they get filled with a sweet and tangy homemade lemon curd. This part is totally optional but I highly recommend it.

How to make lemon frosting for cupcakes
Lemon buttercream starts with my basic buttercream frosting recipe. It’s modified slightly so you get the silkiest, fragrant lemon frosting for 12 cupcakes.
Start by creaming the butter until it’s super smooth. Then add a pinch of salt and 1/3 of the confectioners’ sugar. Whip it until it comes together.
Add the zest and gradually beat in the remaining sugar. Slowly add the lemon juice and whip until you have a fluffy, smooth frosting.
Tips for lemon cupcake success
- When measuring your flour, don’t scoop it out of the container with the measuring cup. Instead, use the spoon and level method or simply weigh it.
- When creaming the butter and sugar together for the cupcakes, it’s important to let it mix for at least 5 minutes. You can mix for up to 10, though! This ensures the cupcakes will have a light and fluffy texture.
- I highly recommend making the lemon curd yourself! Storebought lemon curds can be too sweet or too tart. My recipe is balanced just right and works well with the cupcakes.

Make the frosting
- In a stand mixer fitted with a paddle attachment or with an electric hand mixer, beat the butter on medium-high speed until smooth.

- Beat in the lemon zest. Gradually add in the remaining sugar, one cup at a time. You may need more or less depending on how soft the butter is. Beat on medium-low speed until the sugar is moistened.
- Add the 2-3 tablespoons of lemon juice depending on how creamy you want the frosting to be. Turn the speed up to medium-high and beat until light and fluffy. Scrape down the sides of the bowl as needed.
