"This is my take on a classic apple crumble," says cookbook author and nutrition expert, Katie Cavuto. "But I wanted to pay homage to the natural sweetness of the fruit instead of lobbing on the sugar. Arrowroot powder thickens this whole-fruit filling and fresh ginger, cinnamon, and orange zest lend robust flavors to this treat. And the topping adds more than just crunch; with oats, whole-wheat flour, pumpkin seeds, almonds, and maple syrup, it’s a tasty way to get your nutrients."
