Cake
- 1 cup salted butter (melted and cooled to room temperature)
- 2 cups granulated sugar (400 grams)
- 2 large eggs
- ½ cup milk
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- Zest of 2 lemons
- ¼ cup freshly squeezed lemon juice
- 2¼ cups all-purpose flour (293 grams)
- 1 cup hot water
Frosting
- 3 cups powdered icing sugar
- ½ cup butter (melted)
- 2–3 tablespoons lemon juice
- 1 teaspoon vanilla extract
- Preheat Oven and Prepare Pan: Preheat your oven to 400°F (204°C). Grease an 11×17-inch sheet pan generously with non-stick spray to ensure the cake won’t stick.
- Mix Butter and Sugar: In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth and fully combined.
- Add Eggs: Crack the eggs into the bowl one at a time, whisking thoroughly after each addition to achieve a smooth batter.
- Add Wet Ingredients: Pour in the milk, baking soda, and vanilla extract. Whisk everything together until fully combined and uniform.
- Incorporate Lemon Zest and Juice: Zest two lemons carefully and squeeze out the juice. Add the zest to the batter, stirring gently to distribute the lemon flavor throughout.
- Combine Flour and Wet Ingredients: Gradually stir in the all-purpose flour. Then add the hot water along with ¼ cup of the freshly squeezed lemon juice. Mix slowly and carefully until just combined; avoid overmixing.
- Bake the Cake: Pour the batter evenly into the prepared sheet pan and spread it out smoothly. Bake in the preheated oven for 15-18 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the Cake: Remove the cake from the oven and allow it to cool to room temperature completely before frosting.
- Prepare Frosting: In a medium bowl, whisk together the powdered icing sugar, melted butter, 2 tablespoons lemon juice, and vanilla extract until smooth. Add additional lemon juice gradually if you prefer a thinner consistency.
- Frost the Cake: Spread the lemon frosting evenly over the cooled cake. Let it set at room temperature or refrigerate briefly to speed up the setting process before slicing and serving.
Notes
- Use freshly squeezed lemon juice for the best bright flavor; bottled lemon juice can alter the taste.
- Allow the cake to cool completely before frosting to prevent the glaze from melting and becoming runny.
- If the frosting is too thick, add lemon juice one teaspoon at a time until desired consistency is achieved.
- This cake stores well covered at room temperature for up to 2 days or refrigerated for up to 4 days.
- For extra texture, garnish with lemon zest or thin lemon slices on the frosted cake.
