Not overly sweet, very moist and fluffy texture. The lemon zest is a surprise and is very refreshing. I think I will, next time, push the apples into the batter which is like a bread dough. I thinly cut the apple, as the recipe called for, and wish it had more apple so I'll use 2 apples and slice them a little thicker. Also, pecans or Walnuts would of been a nice addition to the crumble topping. I would recommend this quick recipe.
