Lemon Cupcakes with Lemon Buttercream Frosting
Bright, tender cupcakes bursting with fresh citrus flavor. There’s just something about a really good lemon dessert that just feels like sunshine. And these lemon cupcakes are exactly that—bright, soft, and full of fresh citrus flavor in every bite.
They’re the kind of cupcakes that feel just right for spring and summer, whether you’re bringing them to brunch, setting them out for afternoon tea, or making them just because you’re craving something light and cheerful.
What makes these cupcakes stand out is the layering of lemon flavor. You’re not just relying on one element here—it’s fresh lemon zest rubbed into sugar, freshly squeezed lemon juice, and just a touch of lemon extract to round everything out. The result is a balanced flavor that’s sweet, tangy, and just slightly salty to enhance that natural citrus brightness without overpowering it.
The texture is just as good as the flavor. Thanks to the combination of buttermilk and sour cream, these cupcakes stay incredibly soft and tender with a delicate crumb that feels almost bakery-level. They’re moist without being heavy, and they hold up perfectly under a generous swirl of frosting.
And then there’s the lemon buttercream. It’s rich, creamy, and full of that same fresh citrus flavor, whipped until light and fluffy and piped high for that classic bakery-style finish. Altogether, these cupcakes are simple enough for a weekend bake but polished enough to serve at any gathering that calls for something a little special.

How to Make Perfect Lemon Cupcakes Every Time
- Use room temperature ingredients
This helps everything mix smoothly and creates a more even, tender crumb. - Don’t skip rubbing the zest into the sugar
It brings out the natural oils and gives you a stronger, more natural lemon flavor. - Measure your flour correctly
Too much flour can make cupcakes dense—spoon and level for best results. - Don’t overmix the batter
Mix just until combined to keep the cupcakes soft and light. - Check for doneness properly

Instructions
- Preheat & Prep
Preheat your oven to 350°F and line a 12-cup muffin pan with cupcake liners. - Mix Dry Ingredients
In a small bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside. - Infuse the Sugar
In a separate bowl, combine the granulated sugar and lemon zest. Rub the zest into the sugar with your fingers until fragrant. This step releases the oils and enhances the lemon flavor. - Cream Butter, Oil & Sugar
In a stand mixer fitted with a paddle attachment (or using a hand mixer), cream the lemon sugar, butter, and vegetable oil until light and fluffy, about 2 minutes. - Add Wet Ingredients
Add the egg and sour cream and mix until smooth and fully combined. - Combine Batter
Add half of the dry ingredients and mix until mostly combined. Pour in the buttermilk and lemon juice and mix gently. Add the remaining dry ingredients and mix until smooth, scraping down the bowl as needed. - Fill & Bake
Use a large cookie scoop to fill each cupcake liner about two-thirds full. Bake for about 20 minutes, or until the tops spring back when lightly touched. - Cool
Let the cupcakes cool in the pan for 2 minutes, then transfer to a wire rack to cool completely.
Lemon Buttercream Frosting
- Beat the Butter
Beat the butter for about 5 minutes until pale, light, and creamy. - Add Powdered Sugar
Add half of the powdered sugar and mix on low speed, then add the remaining sugar and continue mixing until smooth. - Add Flavorings
Add lemon juice, heavy cream, lemon zest, salt, and lemon extract. Mix on low, then increase to medium-high and whip for 2–3 minutes until fluffy and smooth. - Frost & Decorate
Transfer frosting to a piping bag fitted with a Wilton 1M tip (or your favorite). Pipe generous swirls onto cooled cupcakes and finish with your choice of garnish.
