1. Preheat oven to 350 degrees F. Grease loaf pan with melted butter or organic coconut oil.
2. In a medium bowl, whisk the flour with the baking powder and salt until well blended. Add the sugar and whisk again.
3. In a separate bowl, combine the yogurt with the coconut oil, and eggs. Add to the dry ingredients and mix all the ingredients until well blended. Mix in the lemon zest, then scatter the berries over the top of the batter and gently fold them in.
4. Pour batter into prepared loaf pan and bake for 45-55 minutes or until a toothpick inserted in the center comes out clean.
5. Allow to cool for 15 minutes, then remove the bread from the loaf pan. Using a toothpick, poke holes into the top of the bread, then pour the glaze all over the top.
6. Allow to cool completely before slicing the bread.
