Italian Lemon/Lime Pound Cake

I think I found this recipe through an email, but either way, here is the original. As usual we've twerked it a bit, preferring more lemon instead of just a mild taste of lemon. Find your balance. Even more twerking we made it a second time using lime instead of lemon. mmmm

3 cups all purpose flour
1 teaspoon baking powder
¼ teaspoon salt
1 cup unsalted butter, softened
2 cups sugar
3 eggs
½ cup buttermilk
½ cup of sour cream
6 tablespoons lemon/lime juice
zest of 2 lemons/limes (about 2 tbsp)
1 teaspoon of vanilla

For the Glaze:
¼ cup butter, softened
1½ cup powdered sugar
4-6 tablespoon lemon juice, at room temperature

Preheat oven to 300°. Sift flour, baking powder, and salt and set aside. In another bowl, cream butter and sugar until light and fluffy. Beat in eggs, one at a time. Mix in the sour cream, lemon juice, vanilla,and lemon zest.
Mix the flour mixture into the butter mixture. Mix in the buttermilk and then add in the remaining flour mixture. Mix just until the flour disappears. Pour the cake batter into a bundt pan that has been generously sprayed with baking spray.
Bake for 60-70 minutes or until a knife inserted in the center of the cake comes out clean. Remove the cake from the oven and allow to cool for 5 minutes. Turn the cake over on a cake platter. Spread half of the lemon glaze over the warm cake so that the glaze can soak into the cake. Let the cake cool completely and drizzle the remaining glaze over the cake.

Cream the butter and slowly add powdered sugar and lemon juice. Beat well until the glaze is a creamy smooth consistency.
