Think celestial rays of sunshine coursing through the vibrant cover of blue sky. The pure taste of summer. The stringent scent of lemon pops with tart clean refreshment. But, in cake form. I had a blast making this cake. I loved the velvety smooth texture of the batter. The fragrant aroma of the lemons reminiscent of lemon ice. And the silky buttery lemon flavor that makes it irresistible not to cut another sliver.

1/2 tsp baking soda
1/2 tsp salt
3/4 cup buttermilk, room temperature
3 tbsp grated lemon zest (about 3 lemons)
1/4 cup fresh lemon juice
1 tsp vanilla extract
1 3/4 cups granulated sugar
12 tbsp (1 1/2 sticks) unsalted butter, softened
3 large eggs plus 1 egg yolk, room temperature

Beat granulated sugar and lemon zest until moist and fragrant, about 1 minute. Reserve 1/4 cup of sugar mixture; cover and set aside. Add butter to remaining sugar mixture and beat until light and fluffy, about 2 minutes. Add eggs and yolk, one at a time, until incorporated. Reduce speed to low.
