Preheat oven to 170 deg C (350 deg F). Grease and Line a 9 x 5 inch loaf pan.
In a large bowl, using an electric mixer on high speed, beat butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition; mix in vanilla. With mixer on low, alternately add flour mixture in three parts, and sour cream in two, beginning and ending with flour mixture.
Place batter in prepared pan and smooth top. Bake until a toothpick inserted in centre of cake comes out clean, 55 to 65 minutes (tent loosely with foil if browning too quickly). Let cake cool completely and then cover with lemon glaze and coconut.
Lemon Glaze: Combine lemon juice and icing sugar and mix until it is a spreadable consistency.
