- 1 teaspoon lemon extract (optional)
- 1 tablespoon fresh lemon juice
- 1 ⅛ cup (135 grams) all-purpose flour
- 1 teaspoon baking powder
- ¾ teaspoon kosher salt
- 1 ½ tablespoons poppy seeds
- ½ cup (120 ml) buttermilk, at room temperature

Key Ingredients for Lemon Frosting
- 1 cup (226 grams) unsalted butter, at room temperature

- ¼ teaspoon kosher salt

Step by Step Instructions
Preparing the Cupcake Batter
Start by preheating your oven to 350°F (175°C) and lining a cupcake pan with liners. In a bowl, combine the sugar and lemon zest, mixing until the sugar turns light yellow. Then, in a mixer, beat together the unsalted butter and oil with the lemon-sugar mixture until fluffy, around 2-3 minutes. Add the eggs one at a time, mixing well after each addition. Next, incorporate the vanilla extract, lemon extract (if using), and fresh lemon juice.
Baking the Cupcakes
In a separate bowl, whisk together the all-purpose flour, baking powder, kosher salt, and poppy seeds. Gradually add this dry mixture to the wet ingredients, alternating with the buttermilk, starting and ending with the flour mixture. Use a cookie scoop to fill the cupcake liners about three-quarters full with batter. Bake for 20-24 minutes, or until a toothpick inserted comes out clean. Let them cool in the pan for 10 minutes before transferring to a wire rack.
Making the Lemon Frosting
While the cupcakes cool, it’s time to prepare the lemon frosting. Beat the unsalted butter and confectioners’ sugar on low speed until combined. Increase to medium-high and beat for about 2 minutes until thick. Add the kosher salt, vanilla extract, and fresh lemon juice, mixing for another 2 minutes. Gradually add heavy cream until you reach the desired frosting consistency.
Assembling and Decorating the Cupcakes
If you’re opting for a filling, core the cooled cupcakes and fill them with lemon curd. Then, frost each cupcake generously with the lemon buttercream. For a decorative touch, you can sprinkle additional poppy seeds on top.
Expert Tips & Tricks
Measuring Flour Accurately
Using a kitchen scale for measuring flour can help prevent adding too much, which may lead to dry cupcakes. Lightly spoon the flour into your measuring cup for a more accurate measurement if you don’t have a scale.
Piping Techniques for Frosting
For beautiful frosting swirls, use a Wilton 1M piping tip. This will give your cupcakes a professional look while making them even more appealing!
Customization Options
Feel free to adjust the flavor by adding more lemon zest or using different extracts. You can also omit the poppy seeds in the frosting if you prefer a smoother finish. The possibilities are endless!
