TIP: Be sure to slice or dice your apples consistently so that they cook evenly.
TIP: Do not skip peeling the apples. Leaving the peels on will affect the consistency and texture of your crisp.

TIP: To make sure this turns out crisp, take the oat mixture, press into balls and break off pieces to sprinkle on top. This allows the best air circulation during baking and turns the topping into crispy pieces that resemble nuggets of oatmeal cookie.
