A few reasons you'll love this cupcake recipe:
- Easy baking recipe - Whether you're a beginning baker or an expert baker, this recipe is easy to follow. To make it even easier, I've included step-by-step photo instructions below!

- Delicious - both the cupcakes and the frosting have a bright lemon flavor that's irresistible. The cupcakes turn out moist with a delightful fluffy texture and the best flavors.
🍋 Cupcake ingredients
Like most cupcake recipes, you'll need some basic dry ingredients and wet ingredients.
- Dry ingredients - You'll need all-purpose flour, cornstarch, baking powder, kosher salt, fresh lemon zest, poppy seeds.
- Wet ingredients - For the wet ingredients, you'll need butter, eggs, sugar, milk, fresh lemon juice, and vanilla extract.
🧈 For best results, make sure you use unsalted butter that has been softened at room temperature. You can take the butter out of the refrigerator about 15-30 minutes before you are ready to start baking. Room temperature butter is soft and creams easily and smoothly in the mixer.
🥚 Make sure you take the egg(s) out of the refrigerator about 30 minutes before you are ready to start baking to allow the egg(s) to come to room temperature. Room temperature eggs mix more smoothly than cold eggs and result in a smooth, even batter.
🧈 Frosting ingredients
For the lemon buttercream frosting, you'll need powdered sugar, more unsalted butter softened at room temperature, lemon juice, milk, and vanilla extract.
Be sure to taste the frosting before using it. If you feel it needs more fresh lemon flavor, you can add some lemon zest or a little more lemon juice.
✅ Step-by-step instructions
The full list of ingredients and instructions are in the printable recipe card at the bottom of this post. Here's a visual step-by-step photo guide to help you along the way as you make these delicious lemon cupcakes.
First, preheat your oven to 375°F. Then line a cupcake pan (muffin pan) with cupcake liners; set aside.
- In a large bowl, whisk together the dry ingredients.
- In the bowl of a stand mixer (or a large mixing bowl and using a hand mixer), beat the softened unsalted butter until creamy, about 2 minutes. Scrape the sides of the bowl down as necessary.
- Add the sugar and beat with the butter for 3-4 minutes.
4. Add the eggs, vanilla, milk, and lemon juice. Mix together just until the ingredients are well blended, about 1-2 minutes.
5. Gradually add the dry ingredients to the wet ingredients.
6. Beat all of the ingredients together until the batter is smooth and all ingredients are well incorporated.
7. Scoop the muffin batter into the prepared muffin tin.
8. Bake at 375°F for 5 minutes. Then turn down the heat to 350°F and bake for an additional 15-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. While the cupcakes are baking, make the frosting.
Make the frosting
- In the bowl of a stand mixer, cream the butter for 2-3 minutes until light and fluffy. Add the powdered sugar, cream, vanilla, and lemon juice. If you want thicker frosting, add a little more powdered sugar until the frosting reaches your desired consistency.
Assemble
- Allow the cupcakes to cool in the pan for 5 minutes. Then transfer to a wire rack to cool completely before frosting the top of the cupcakes.
👩🏻🍳 Recipe FAQs
Baking cupcakes or muffins at a slightly higher heat helps the baked goods rise early on. This creates the desirable bakery-style rounded dome effect on the top of cupcakes and muffins. Then turning the heat down helps the desserts bake more evenly for the remaining bake time.
Store unfrosted cupcakes in an airtight container at room temperature for up to 5 days. Store frosted cupcakes in an airtight container in the refrigerator for up to 4 days.
🍽 Serving ideas
If you're baking these cupcakes for a spring brunch or lunch event, they'd go well with other spring desserts like Strawberry Crinkle Cookies, Mini Citrus Bundt Cakes, and Key Lime Cookies.
🍳 Kitchen tools and equipment
Ready to make this recipe? Here are the kitchen tools and equipment you'll need:
- Muffin tin - This cupcake recipe makes about 15-17 cupcakes, so you could use two muffin tins. Or, use just one muffin tin and work in batches.
- Cupcake liners - Use whatever cupcake liners you have on hand to line the insides of the muffin tin. If you don't have cupcake liners, you can lightly grease the insides of the muffin tin openings with butter.
- Stand mixer - A stand mixer makes quick work of combining the batter. But if you don't have one, you can use a hand mixer and a large mixing bowl.
- Spatula - A silicone spatula makes it easy to scrape down the sides of the stand mixer bowl.
- Cookie scoop - A large cookie scoop (or ice cream scoop) or ¼ cup measuring cup helps you bake equal portions of batter.
- Cooling rack - Use a cooling rack to help the cupcakes cool evenly on the countertop.
- Piping bag - use a piping bag for the frosting.
