Ingredients Method Notes

Ingredients
  

For the Lemon Cupcakes
  • 1 1/4 cups all-purpose flour
  • 3/4 tsp baking powder
  • 1/4 tsp baking soda
  • 1/4 tsp salt
  • 1/4 cup unsalted butter room temperature
  • 1/4 cup vegetable oil
  • 3/4 cup sugar
  • 1/4 tsp vanilla extract
  • 2 large eggs
  • 6 tbsp milk
  • 1/4 cup fresh lemon juice
  • 1 tbsp lemon zest
For the Lemon Buttercream
  • 1 cup unsalted butter room temperature
  • 4 cups powdered sugar
  • 1/2 tsp vanilla extract
  • 4 –5 tbsp lemon juice
  • 1 tsp lemon zest
  • Salt to taste

Method
 

  1. Preheat oven to 350°F (176°C) and line a cupcake pan with liners. This step makes sure your oven is ready and the cupcakes bake evenly from the start.
  2. In a bowl, mix flour, baking powder, baking soda, and salt. Give it a quick whisk so everything is evenly combined and set it aside.
  3. In a separate large bowl, beat butter, oil, sugar, and vanilla until the mixture becomes light and fluffy. Honestly, this step is important because it helps create soft and airy cupcakes.
  4. Add the eggs one at a time, mixing well after each addition so everything blends smoothly.
  5. Now add the dry ingredients in parts, mixing gently. Don’t overmix here—just combine until you don’t see dry flour.
  6. In another small bowl, mix milk with lemon juice, then slowly add it to the batter along with lemon zest. This adds that fresh lemon flavor we want.
  7. Add the remaining dry ingredients and mix until the batter is smooth and well combined. Trust me, gentle mixing keeps the cupcakes soft and light.
  8. Fill the liners about 3/4 full and bake for 15–18 minutes, or until a toothpick inserted in the center comes out clean. Once baked, let them cool completely before frosting so the buttercream doesn’t melt.
  9. For the frosting, beat the butter until smooth, then gradually add powdered sugar and mix well. Add vanilla, lemon juice, lemon zest, and a pinch of salt, and mix until creamy and fluffy.
  10. Finally, frost the cooled cupcakes and serve. Honestly, this final step brings everything together and makes them taste even more delicious.

Notes

Honestly, a few small details can really improve the final result. Make sure all your ingredients are at room temperature so everything blends smoothly and gives you a soft texture. Don’t overmix the batter after adding the dry ingredients—trust me, gentle mixing keeps the cupcakes light and fluffy. Fresh lemon juice and zest are highly recommended because they give a brighter, more natural flavor compared to bottled options. Also, always let the cupcakes cool completely before adding the frosting, otherwise the buttercream can melt and lose its shape.
