Stir the lemon juice into the milk, and set aside for 5 minutes.
Mix the flour, ½ cup oats, baking soda, and salt together in a bowl.
Pour the milk mixture, molasses, and olive oil into the dry ingredients, and mix until combined.
Lightly spray a loaf pan with cooking spray, and pour the batter into it.
Use a knife to lightly score down the center of the loaf (this will give the bread somewhere to rise into), and sprinkle with remaining 1 tablespoon oats.
Bake for 45-55 minutes, until a toothpick inserted into the center of the loaf comes out clean.
Allow to cool in the pan for 5-10 minutes, then remove and cool completely on a wire rack.
