Apple And Plum Crumble

This apple and plum crumble is a delicious way to utilize an abundant apple and plum harvest in the fall. The recipe features mixed fresh apples and plums topped with a crunchy crumble topping and baked in the oven to a golden brown perfection. It’s a perfect fruit dessert for a crowd!

Just like my apple blueberry crumble and blackberry apple crumble, making this apple plum crumble dessert is much easier than a crumble apple pie. It’s incredibly quick, and requires only 10 minutes of preparation time when your crumble topping is made in advance.

If plums aren’t available, don’t worry, feel free to substitute with other fruits. Nectarines, peaches, cherries or pears work as well. Also make sure to try this strawberry crumble/crisp or this peach crumble with oats.

What You Need For This Recipe

There are 2 components in this apple and plum crumble recipe: the apple and plum layer (as the filling) and the oat crumble topping.

For Apple And Plum Filling

  • Plums – opt for black, purple, red, or yellow colored skin. They all work well. Inside, the flesh of plums should be moderately soft and juicy.
  • Apples – you can use just one variety or, for added depth of flavor, use an assortment of varieties. I used gala apples due to their crisp texture and mellow sweetness. The sweeter they are the less sugar you need to add.
  • Arrowroot flour – or any starchy flour, it helps absorb moisture and thicken the juices so that your filling isn’t too runny.
  • Lemon juice – to increase the tartness (but it’s optional if you’re using tart plums).
  • Maple sugar – coconut sugar, brown sugar, or maple syrup also works if you prefer a healthier sweetener. Add less if your fruits are really ripe and sweet.
  • Cinnamon – for flavor depth.

Crumble Topping Ingredients

  1. Rolled oats – rolled oats (not steel cut or quick oats). For a healthier adaptation, I use gluten free organic rolled oats.
  2. Flour – use one plain type or a mix (your choice). Finer (starchier) flours will yields a more golden brown surface. Whole grain flours are healthier but they will change the texture and flavor a bit.
  3. Butter – use grass fed butter, ghee or use vegan butter / coconut oil – to keep it vegan & dairy free.
  4. Maple sugar – to keep the recipe refined sugar free. Brown sugar or coconut sugar are also wonderful.
  5. Walnuts – provide crunch and a rich sweet taste. Feel free to use your favorite nuts or omit them.
  6. Spices: cinnamon, cardamom and a touch of salt.

How To Make Apple and Plum Crumble

Before you start, place your butter in the freezer for at least 1 hour.

Step 1. Make the crumble topping:

  • If you have a food processor: add the cold (frozen) butter and the flour to the bowl of a food processor and pulse the mixture until you have a chunky / crumb like mixture.
  • To the butter and flour mixture, add the spices, sugar, crushed walnuts and rolled oats, mix by hand or with a spatula until combined. For step-by-step instructions and extra tips see my crumble topping recipe.

  • If you prefer a clumpy topping (instead of a sandy texture) then after mixing everything let it sit at room temperature for 5-8 minutes ant then use your hand to clutch and squash the mixture. The heat from your hand will help create lumps.

Step 2. Prepare the filling:

  • Chop the apples and the plums into thin wedges.
  • In the backing pan (9-inch square pan) add the prepared apples and the plums, maple sugar, lemon juice, cinnamon and flour and toss to coat. I used the same pan for mixing that I’m using for baking (to reduce the dirty dishes).
  • Spread the apple and plum filling in an even layer.

Step 3. Assemble the plum and apple crumble and bake:

  • Preheat the oven to 360°F.
  • Scatter the oat crumb evenly over the surface of the apple and plum layer.
  • Bake in the oven for about 35-38 minutes, or until the topping is slightly golden brown.

Step 4. Cool and serve!

  • Once it’s crisp and golden remove from oven and let it cool.
  • Serve the apple and plum crumble warm, cold or room temperature. I find that if you let it cool a bit the juices harden and get a caramelized texture, which looks absolutely fantastic when served with some ice cream.

Recipe FAQs

Do you have to peel plums before baking?

No. The skin keeps the plums from disintegrating, especially when they are really ripe.

How long does apple plum crumble last in the fridge?

Up to 2-3 days, then it tends to turn soggy.

Can you freeze apple and plum crumble?

It can be frozen for up to 3 months either baked or un-baked. For best results is best to freeze unbaked and keep the fruits and topping in separate containers. Then combine and bake the apple and plum crumble whenever you’re ready.

How to thaw / reheat the apple and plum crumble?

No need to thaw. Just place it in your preheated oven (360 degrees F) straight from the freezer and add a few minutes on to the cooking time. To reheat just cover with a foil and reheat at 360°F / 182°C in the oven until warmed through.

Can you make the apple and plum crumble without oats?

Sure, just remove the oats from the recipe and add more flour and nuts to replace the oatmeal. Alternatively you can use whole grain flours like sorghum flour and brown rice or almond flour for a grain free version.

Can you make the apple plum crumble gluten free?

Absolutely. Replace the flour with a gluten free flour mix and use gluten free oats.
