Pre-heat oven to 350°. Line a loaf pan with parchment paper.
In a medium bowl mix the flour, baking powder, salt and lemon zest. Set aside.
In the bowl of a stand mixer (or using a handheld beater) beat the butter, sugar, eggs and vanilla for 2 minutes.
Alternate mixing in the flour mixture and the lemon juice. Add in the sour cream and mix until combined.
Pour batter into prepared loaf pan and add in the frozen strawberries.
Bake for 40-45 minutes until a toothpick entered into the center comes out clean.
Let cool completely on a wire rack.
While the lemon loaf is cooling prepare the glaze.
