Preheat the oven to 325 degrees.
Generously grease and flour a bundt pan.
Combine the flour, baking powder, salt and set aside.
Cream together the softened butter, sugar, eggs, buttermilk, sour cream, lemon juice, lemon zest and vanilla extract.
Slowly fold in the flour mixture.
Pour the batter into the prepared bundt pan.
Bake for 1 hour 10 minutes, or until completely done.
While the lemon pound cake is baking, combine the ingredients for the glaze.
Once the cake is done baking, move from oven and let cool a few minutes.
Gently turn the bundt pan upside down to carefully remove the cake from the pan. Set aside.
Drizzle the glaze over the cake while it's still warm.
Let sit until cool.
Serve & enjoy!
