Instructions

Step 1: Prepare the Cupcakes

  4. Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract and lemon zest.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with milk, beginning and ending with the dry ingredients. Mix until just combined.

  3. Pipe or spread the frosting on top of the cupcakes.
  4. Optional: Garnish with extra lemon zest or a small slice of lemon for decoration.
