Instructions
Preheat Oven and Prepare Pans:
Preheat your oven to 350°F (175°C). Line a cupcake pan with paper liners.
Mix Dry Ingredients:
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
Cream Butter and Sugar:
In a large bowl, beat the butter and sugar together until light and fluffy, about 3-4 minutes.
Add Eggs and Flavorings:
Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract, lemon zest, and lemon juice.
Combine with Dry Ingredients and Buttermilk:
Alternately add the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined, being careful not to overmix.
Bake:
Divide the batter evenly among the lined cupcake cups, filling each about 2/3 full.
Bake for 18-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.
Remove from the oven and allow to cool in the pan for a few minutes, then transfer to a wire rack to cool completely.
Make the Lemon Buttercream Frosting:
Beat the butter for the frosting until creamy. Gradually add the powdered sugar, one cup at a time, beating well on medium speed.
Stir in the lemon zest and juice, and a pinch of salt, and beat until smooth and creamy. Adjust the consistency with more lemon juice or powdered sugar if necessary.
Decorate the Cupcakes:
Once the cupcakes are completely cool, frost them with the lemon buttercream using a piping bag or a knife.
Garnish and Serve:
Optionally, garnish with a small piece of lemon zest, a thin slice of lemon, or edible flowers.
