You MUST try this frosting recipe. If you like lemon - you will die. For sure.
Lemon Frosting (follow these directions!)
from Sprinkles2 sticks unsalted butter, firm but not cold
zest of 1 lemon
1/8 tsp salt
3 3/4 cup powdered sugar, sifted
1/2 tsp salt
2 1/2 tsp fresh lemon juice
In a bowl of an electric mixer fitted with the flat beater, beat the butter, zest and salt on medium speed until light and fluffy - about 2 minutes. Reduce speed to low and gradually add the sugar and beat until thoroughly blended. Add the vanilla and lemon juice and beat until smooth. Do not overmix, or the frosting will incorporate too much air. It should be creamy and dense like ice cream. Add milk, 1 tsp at a time, if frosting does not have a spreadable consistency (I didn't need to).
**Warning: Careful if you make this - you might it eat it straight out of the bowl.
