3 c. cake flour (no substitutions here–you really need the lightness of cake flour)
1 tsp. baking powder
1/2 tsp. salt
1/2 tsp. baking soda
2 c. sugar
5 large eggs
2 tsp. vanilla extract
4 Tbsp. freshly squeezed lemon juice
Zest of 2 lemons (just zest the other lemons before you squeeze them)
1 c. buttermilk
In the bowl of an electric mixer fitted with the paddle attachment, beat butter and sugar on medium speed until light and fluffy, 4-5 minutes. Don’t go skimping here–you want the mixture to be almost white and super fluffy. This is absolutely essential to the outcome of the cake.
With mixer on low speed, alternate adding flour mixture and buttermilk, beginning and ending with the flour mixture and beating until fully incorporated.
Using a standard cookie scoop, place about 2 scoops of batter into each muffin cup. Fill these almost to the top–due to the final texture (again, think super-moist and light pound cake), these cupcakes won’t have a nice, curvy crown, but that’s okay–no one will ever know or care.
Bake about 20-25 minutes or just until a toothpick inserted into the center of one of the cupcakes comes out clean. You don’t want to overbake these even a bit, or they’ll start to lose their delicious moisture. Remove from oven and cool completely. Frost with lemon buttercream and garnish with strawberries, blueberries, raspberries, or fresh mint leaves.
1 1/4 c. butter (2 1/2 sticks)
2 tsp. grated lemon rind
3 Tbsp. fresh lemon juice
3 c. powdered sugar
