Whisk together flour, baking soda, baking powder and salt in a large bowl.
In a separate bowl (or the base of a stand mixer), beat the eggs, sugar, butter, vanilla extract, lemon extract and lemon juice until thoroughly combined.
Add the dry ingredients, a little at a time, to the egg mixture; beat till smooth. Add oil and mix well. Pour batter into a well-greased 8½" x 4½" loaf pan.
While loaf is cooling, make the icing: Combine icing ingredients in a small bowl. Mix on low with an electric mixer or whisk till all the lumps have disappeared. When the lemon loaf has cooled, frost the top of the loaf with the icing. Wait for the icing to "set up", then slice into 8 - 1 inch slices. Enjoy!
