Allow the crisp to cool for at least 10-15 minutes before serving. Serve warm or at room temperature.
Notes
Use apples that are great for baking. You want the apple to hold up and not just turn to mush. Some options include Fuji, Granny Smith, Honey Crisp, or Braeburn.
If using frozen cranberries, increase the baking time by 10-15 minutes.
If the crisp is browning too quickly, tent it loosely with a piece of foil.
Cook until the crisp is bubbling around the edges and the topping is golden brown.
Allow the finished crisp to cool for 10-15 minutes before serving.
Serve with a scoop of vanilla ice cream or a dollop of whipped cream.
