Zen Cupcake

Step 1. Preheat your oven to 350°F (175°C) and line a standard muffin tin with 12 paper liners.

Step 2. In a medium-sized bowl, whisk together the flour, baking powder, and salt until well combined.

Step 3. In a large mixing bowl, cream the softened butter and granulated sugar together using an electric mixer until the mixture is light and fluffy.

Step 4. Beat in the egg, followed by the sour cream, milk, lemon juice, and lemon zest. Mix until the wet ingredients are smooth.

Step 5. Gradually add the dry ingredients into the wet mixture. Stir by hand or on low speed just until the flour disappears; do not overmix.

Step 6. Scoop the batter into the prepared cupcake liners, filling each about two-thirds of the way full.

Step 7. Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a cupcake comes out clean.

Step 8. Allow the cupcakes to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting.

Step 9. Prepare the frosting by beating 0.5 cup of softened butter with powdered sugar, 1 tablespoon of lemon juice, and a pinch of zest until light and airy.

Step 10. Pipe or spread the frosting generously onto the cooled cupcakes and garnish with a small lemon wedge if desired.
