Shopping List

  • Extra-virgin olive oil
  • 5 large green apples
  • Cranberries, fresh or frozen (may be omitted)
  • Corn starch
  • Dark brown sugar
  • Maple syrup
  • Vanilla extract
  • Butter
  • Coconut oil
  • Oats, rolled & quick
  • Sliced almonds
  • Cinnamon
  • Nutmeg

This autumn-perfect apple crumble is adapted from an Ooni recipe. It's ideal for a cast-iron pan, if you have one. You can easily make this in an Ooni pizza oven (you'll definitely need a cast-iron pan for the Ooni) or your kitchen oven (use any type of pan).

The crispy crumble is best made with tart green apples. It's spiced with maple syrup and cinnamon. Enjoy it warm for dessert (sublime with a scoop of ice cream) and have the leftovers for breakfast the next day.

Don’t like cranberries? Sub in raisins or omit the cranberries and slightly increase the amount of apple.

Note that the recipe calls for both rolled oats and quick oats.

Helpful to have: A kitchen scale and an infrared thermometer to measure pizza oven temperature.

Ingredients

  • Extra virgin olive oil (for the pan)
  • 5 large green apples, peeled & chopped
  • 3.5 oz. (100 grams) fresh or frozen cranberries
  • 1 tbsp. corn starch
  • 4 tbsp. boiling water
  • 2.8 oz. (80 grams) dark brown sugar
  • 4 tsp. vanilla extract
  • 8 tsp. maple syrup

Crumble topping

  • ½ stick of butter, melted
  • 2.8 oz. (80 milliliters) coconut oil, melted
  • 3.5 oz. (100 grams) rolled oats
  • 3.5 oz. (100 grams) quick oats
  • 6 tsp. all-purpose flour
  • 1.8 oz. (50 grams) sliced almonds (can sub in chopped walnuts or pecans)
  • 3.5 oz. (100 grams) dark brown sugar
  • ½ tsp. cinnamon
  • ¼ tsp. nutmeg

Prep

The Ooni pizza oven should be at a low-medium temperature or 350° F. Use an Ooni infrared thermometer to check the pizza oven temp. If you’re baking in a regular oven, heat it to 350° F.

Brush an Ooni cast-iron skillet (or a 9- to 10-inch cast-iron pan) with the olive oil.

Prepare the apples.

Make

First, make the crumble topping.

In a bowl, combine all of the topping ingredients and set aside.

Place the cast-iron pan in the oven to warm up while you prepare the rest of the crumble.

Now, make the apple mixture.

In a bowl, stir the boiling water into the corn starch, mix well and set aside.

Remove the warmed skillet from the oven, add the chopped apples. Bake for 5 minutes or until the apples are soft.

Remove from oven and set aside.

In another bowl, combine the corn starch mixture, brown sugar, maple syrup, and vanilla.

Pour this over the apples, tossing to coat all of the fruit. Add cranberries or raisins, if using.

Return the pan to the oven and bake about 7 minutes or until the apples turn a light golden color.

Sprinkle the crumble topping over the apples and return to oven. Bake for 10 minutes or until topping is toasted and crunchy.

Serve warm, with a scoop of ice cream, if desired.
