Ingredients You’ll Need

Step by Step to Make Soft Butter Lemon Cupcakes

1: Preheat and Prep Your Tin

• Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
• Let all your ingredients come to room temperature this ensures smooth batter mixing.

2: Mix Dry Ingredients

• In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well combined.
• Set this aside while you cream the butter and sugar.

3: Cream Butter and Sugar

• In a large bowl, beat the butter with sugar using a hand mixer or stand mixer until pale and fluffy about 3 minutes.
• This creates the tender, airy texture we want in the cupcakes.

4: Add Eggs and Flavorings

• Beat in the eggs one at a time, mixing well after each.
• Add the vanilla extract, lemon zest, and fresh lemon juice. Mix until fully combined.

5: Combine Wet and Dry

• With the mixer on low speed, add half of the dry ingredients to the wet mixture.
• Pour in the milk, then finish with the remaining dry ingredients. Mix until just combined do not overmix.

6: Fill and Bake

• Divide the batter evenly among the 12 cupcake liners, filling each about ¾ full.
• Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean and tops are lightly golden.

7: Cool Before Frosting

• Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
• Frost only when they’re fully cool to prevent the buttercream from melting.

How to Make the Lemon Buttercream Frosting

1: Start with Room Temperature Butter

• Place 1 cup (227g) of unsalted butter in a large bowl. It should be soft enough to press your finger into, but not melty.
• Beat the butter on medium speed for 2-3 minutes until it’s smooth and creamy. This ensures a fluffy base.

2: Add Powdered Sugar Gradually

• Sift 3 ½ cups (392g) of powdered sugar to remove any lumps.
• With the mixer on low, add the sugar ½ cup at a time, mixing well after each addition to prevent clouding your kitchen in sugar dust.

3: Mix in Flavor

• Once the sugar is incorporated, add 2 tablespoons of fresh lemon juice, 1 tablespoon lemon zest, 1 teaspoon vanilla extract, and a pinch of salt.
• Beat on medium high speed until the frosting is smooth, fluffy, and slightly glossy about 2-3 minutes more.

4: Frost the Cooled Cupcakes

• Use a piping bag with your favorite tip or simply spread with a knife or offset spatula.
• Top with a sprinkle of extra lemon zest or a thin lemon slice for visual flair.

Tips for the Best Soft Butter Lemon Cupcakes

• Don’t skip the lemon zest: It adds a concentrated citrus punch that lemon juice alone can’t provide.
• Use room temperature dairy and eggs: They mix more evenly and prevent the batter from curdling.
• Cream the butter and sugar properly: This traps air for a lighter crumb.
• Don’t overmix once the flour is in: Mix just until the ingredients come together to keep cupcakes soft.
