This sweet (but not too sweet) dessert is just as quick and easy as apple crisp, but twice as interesting. Roasted, salted macadamia nuts and rolled oats make for an extra-crispy streusel topping. Any apples are okay to use, but we prefer the way honeycrisp or fuji apples maintain their crisp texture during baking. The dessert is baked in a rectangular baking dish, but its totally okay to use 6-ounce ramekins instead, for a slightly fancier single-serve presentation. Be sure to serve this dessert straight out of the oven, as itll get soggy if it sits in the refrigerator (which we think is ok for breakfast, topped with yogurt). Pair it with big scoops of vanilla ice cream.
