Step-by-Step Guide to Making Lemon Cupcakes

1. Preparation is Key

• Start by placing 4 tablespoons of unsalted butter, 2 large eggs, and 1/2 cup of milk on the counter to reach room temperature. This ensures smoother blending and a better texture.
• Preheat your oven to 350°F and line a 12-well muffin pan with paper liners.

2. Prepare Your Dry Ingredients

• In a medium bowl, whisk together 1 1/2 cups of flour, 1 teaspoon of baking powder, and 1/4 teaspoon of baking soda. This step removes lumps and ensures even distribution of leavening agents.

3. Zest and Juice the Lemons

• Finely grate the zest of 2 lemons to get 2 tablespoons of zest. Then, juice 1 1/2 lemons to yield about 5 tablespoons. Save the remaining lemon half for garnishing slices, if desired.

4. Create the Lemon Sugar

• In a large mixing bowl, combine 1 cup of sugar, 1 tablespoon of lemon zest, and 1/2 teaspoon of kosher salt. Rub them together with your fingers until fragrant and well-combined.

5. Cream the Butter and Sugar

• Add 4 tablespoons of butter and 1/4 cup of vegetable oil to the lemon sugar. Beat on medium speed until the mixture becomes fluffy, which takes about 3–5 minutes.

6. Add the Eggs and Wet Ingredients

• Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Then, mix in 4 tablespoons of lemon juice, the milk, and 2 teaspoons of vanilla extract. The batter might appear slightly curdled—don’t worry, this is normal.

7. Combine Everything

• Gradually add the dry ingredients in two parts. Mix gently until just combined, being careful not to overmix.

8. Fill the Muffin Pan and Bake

• Divide the batter evenly among the muffin liners, filling them almost to the top. Bake for about 20 minutes, or until a toothpick inserted in the center comes out clean.

9. Cool the Cupcakes

• Allow the cupcakes to cool in the pan for a few minutes before transferring them to a wire rack to cool completely.

Making the Frosting

1. Whisk the Powdered Sugar

• In a large bowl, whisk 3 cups of powdered sugar to remove any lumps.

2. Cream the Butter and Lemon Zest

• Beat 3/4 cup of butter with 1 tablespoon of lemon zest and 1/4 teaspoon of salt until smooth and creamy.

3. Incorporate the Powdered Sugar

• Add the powdered sugar, 1/2 cup at a time, and beat on low speed until fully combined.

4. Add the Liquid Ingredients

• Mix in 1 tablespoon of milk and the remaining lemon juice. Beat on medium speed until the frosting is light and fluffy, about 3–5 minutes.

5. Decorate the Cupcakes

• Spread or pipe the frosting onto the cooled cupcakes. Garnish with lemon slices and a sprinkle of yellow sanding sugar if desired.

Tips for the Best Lemon Cupcakes

• Don’t Skip the Zest: The zest holds concentrated lemon flavor, so it’s essential for that zesty kick.
• Room Temperature Ingredients: This ensures smooth mixing and an even texture.
• Don’t Overbake: Keep an eye on your cupcakes—overbaking can make them dry.

Variations to Try

1. Lemon-Blueberry Cupcakes

Add 1/2 cup of fresh blueberries to the batter for a fruity twist.

2. Lemon Poppy Seed Cupcakes

Mix in 2 tablespoons of poppy seeds for a fun texture and extra flavor.

3. Vegan Lemon Cupcakes
