Preheat oven to 350F and spray a regular size loaf pan with some cooking spray.
In a bowl whisk the eggs and sugar together. Sti in the yogurt, apple sauce, lemon juice, lemon extract and lemon zest.
Mix in the flour and baking powder, pour batter into your loaf pan and bake in the oven for 45-50 minutes or until loaf is baked right through.
Let cool then remove carefully from the pan. In a small bowl mix your icing sugar and lemon juice together to make the glaze, pour over the loaf. Cut into 10 equal servings. *Note- this loaf is a bit denser of a loaf due to ingredients used, it will drop a little after cooling.
The loaf is best stored in the fridge after day one and will freeze well.
