Apples with Oat Cinnamon Crumble

Introduction

You get soft baking apples under a topping of rolled oats, flour, brown sugar, and cold butter or margarine, baked until the top is dark brown. It takes about 45 minutes start to finish and works well as a straightforward dessert for a weeknight dinner or a make-ahead bake.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 6

Ingredients

• 6 cups sliced and cored baking apples (for example, Granny Smith)
• ½ cup (100 g) all-purpose flour
• ½ cup (100 g) rolled oats
• ¾ teaspoon (3 g) cinnamon
• ⅓ cup (75 g) cold butter or cold margarine
• ⅔-¾ cup (120-150 g) brown sugar

Instructions

1. In a medium bowl stir together flour, brown sugar, and oatmeal. If the room temperature is a bit warm, you should cool this mixture in the fridge.
2. Prepare the apples. This should be completed before mixing butter into the topping. It is helpful to choose apples that do not brown quickly; Granny Smith apples are a good choice. Do not use Red Delicious apples; they turn to mush. Place the apples into a 9-inch (23 cm) square baking dish; glass is best.
3. Add the butter or margarine to the topping. Mix it via a slicing action, so that the butter or margarine forms tiny little chunks and does not melt or smear. A pair of butter knives, used like scissors, is good for this. You must work quickly once you start this step.
4. Sprinkle the topping onto the apples. You may pat it down just a bit.
5. Bake for about 30 minutes in a 375 °F (190°C) oven. Do not remove the crisp before the top is dark brown. Black spots indicate burning. It is better to burn a few small spots, which you can then remove, than to risk undercooking the topping.

Variations

• Swap 2 cups of the baking apples for firm pears if you want a softer filling and a slightly milder fruit flavor.
• Use cold margarine instead of cold butter to make the crumble dairy-free; the topping will still crisp, though the flavor is a little less rich.
• Choose ⅔ cup brown sugar for a tarter, more apple-forward result, or use ¾ cup for a deeper caramel note and sweeter filling.
• Replace the rolled oats with quick oats if that is what you have; the topping will be finer and less chewy.

Tips for Success

• Finish slicing and coring the apples before you add the butter or margarine to the topping, so the fat stays cold.
• Use firm baking apples such as Granny Smith and avoid Red Delicious, which break down too fast.
• Cut the butter or margarine in with a slicing motion until you have small visible pieces; if it smears, the topping can bake up dense instead of crumbly.
• Bake until the top is dark brown, not pale golden, so the flour and oats taste toasted rather than raw.

Storage and Reheating

Let the crumble cool completely, then cover the baking dish tightly or transfer portions to an airtight container. Refrigerate for up to 4 days.

You can freeze it for up to 2 months in a freezer-safe container, but the topping will soften a bit after thawing.

Reheat larger portions in a 350 °F oven for 10 to 15 minutes, uncovered, until warmed through. For single servings, microwave for 30 to 60 seconds; the topping will be softer than oven reheating.

FAQ

Can you use apples other than Granny Smith?

Yes. Choose any firm baking apple that holds its shape, such as Honeycrisp or Braeburn, and avoid apples that turn mushy.

Why does the topping need to get dark brown?

The flour and oats need enough time to toast fully. If you pull it early, the topping can taste raw and have a sandy texture.

Can you assemble it ahead of time?

Yes. Slice the apples, make the topping, and refrigerate the unbaked dish for up to 1 day; bake it straight from the fridge and add a few extra minutes if needed.

Can you use margarine instead of butter?

Yes. Keep it cold and cut it in the same way so it stays in small pieces and bakes into a crumbly topping.
