Cream the butter and sugar in a bowl.
Beat in the eggs, one at a time, followed by the sour cream and vanilla.
Mix the flour, baking powder, baking soda, salt and cinnamon in another bowl.
Mix the wet ingredients into the dry ingredients before mixing in the strawberries.
Pour the batter into a greased 9X5 inch loaf pan and bake in a preheated 350F/180C oven until a toothpick pushed into the center comes out clean, about 50-60 minutes.
Mix everything until the sugar has melted into a thick sauce before drizzling over the cooled bread.
