Helpful Apple Crumble Baking Tips

Buy the freshest apples. The fresher the apple, the more juice to produce that yummy liqueur that collects in the bottom of the pan and soaks into the crumble topping. Look for “new crop” signs in your grocery store.

Use an apple slicer for easy cutting.

Don’t bake in ceramic. Ceramic dishes are pretty (that’s why you’ll see them in my photos), but if you bake apples in them, much of the juice will evaporate because of how ceramic retains heat. I recommend a light colored aluminum cake pan if you have one- it’s quick to heat up and quick to cool down. (Here, our glass pie pan is a lifesaver - but with glass, you MUST put it either on a trivet or some kind of insulated pie cover, never a cold surface!)

Salt is good. A dash of salt makes the flavors pop.

Let it cool completely. As tempting as it may be, don’t serve hot out of the oven. Baked apples benefit from a rest. You’re better off letting it cool to room temperature, then warming it slightly in the oven or microwave. Believe it or not, it tastes even better the second day!


Ingredients

1/2 cup white whole wheat flour you may substitute all purpose flour if you prefer (used 2 tablespoons all purpose)
1/2 cup old fashioned oats (used granola)
1/3 cup light brown sugar firmly packed
1 teaspoon light brown sugar firmly packed
1/2 teaspoon cinnamon (apple pie spice)
1 pinch sea salt
6 tablespoons butter melted and divided
1 pound baking apples cored and sliced into eighths (I recommend Honeycrisp or Pink Lady / Cripps Pink)
1 handful (1/2 cup or so dried cranberries)

Instructions

Preheat the oven to 375.
Place the apple slices into a pan. Drizzle 1 teaspoon of melted butter over the apples and reserve the rest of the butter. Sprinkle 1 teaspoon of brown sugar over the apples. Toss or stir in the pan to coat the apples.
Place the flour, oats, cinnamon, salt, and 1/3 cup of brown sugar in a bowl. Stir to combine. Pour in the remaining melted butter and stir until well combined.
Spoon the mixture evenly over the apples, allowing it to remain somewhat clumped as you do so.
Bake for 25 to 30 minutes, or until the top is golden brown and the apples are easily pierced with a fork. Let cool almost to room temperature before serving.

Very good with a scoop of ice cream!
