- 2 cups all-purpose flour, spooned and leveled
- 1 and 3/4 cup granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 2 tablespoons lemon zest (from 4 lemons)
- 3/4 cup lemon juice (from the same 4 lemons)
- 1/4 cup water
- 1 cup (2 sticks) butter
- 1/2 cup sour cream
- 2 large eggs
For the glaze
- 4 and 1/2 to 5 cups powdered sugar, sifted
- 1/2 cup lemon juice (from about 2-3 lemons)
- lemon slices, quartered (to garnish)
- raspberries, to garnish
Instructions
- Preheat your oven to 375 degrees F. Spray a half sheet pan (18x12 inches) with nonstick spray, or line with parchment paper. Set aside.
- In a large bowl or stand mixer, add the dry ingredients: 2 cups flour, 1 and 3/4 cup sugar, 1 teaspoon baking soda, 1/2 teaspoon kosher salt. Whisk together, then use a microplane grater to zest 4 lemons into the dry ingredients. You should get about 2 tablespoons. Whisk the zest into the dry ingredients and set aside.
- Juice 4 lemons (I love to use an electric juicer), or as many as you need to get to 3/4 cup. Add it to a small saucepan with 1/4 cup water.* Add 1 cup (2 sticks) butter to the saucepan and set over medium high heat. Stir occasionally until the butter melts and the mixture comes to a boil, with bubbles all across the top.
- Pour the wet ingredients into the dry ingredients and stir or beat until combined.
- Add 1/2 cup sour cream and 2 large eggs. Beat until thoroughly combined, making sure to scrape the bottom and sides of the bowl.
- Pour the batter into the prepared pan, and spread to the edges. Bake at 375 for 12-14 minutes until the edges are light brown and have started to pull away from the edges of the pan. A toothpick inserted into the center of the cake should come out with no wet batter on it.
- Let the cake cool completely on a wire cooling rack.
- When the cake is completely cool, make the glaze. Sift 4 and 1/2 cups of powdered sugar into a medium bowl. Add 1/2 cup lemon juice and whisk until completely smooth. Add more powdered sugar to get the consistency you like.
- Drizzle the glaze over the top of the lemon cake and spread to the edges. Let the glaze set up for about an hour or two, until hardened on top.
- Slice and serve! Top each slice with a quarter of a lemon slice and a raspberry, if desired.
- Store on the counter for the first 2-3 days, then store in the fridge.
