This is one recipe I think you’ll make again and again. So simple to make yet so full of flavor.

A crumble is similar to a crisp, except it has more of a streusel topping.

We used a mix of apples we had on hand, and I’ve tested this recipe both with dairy and non-dairy ingredients with perfect results each time.

Ingredients Needed:

  • apples – any kind you have or like will work. Some may be a little more watery than others, but this will simply result in more of that delicious sauce
  • thickener (cornstarch or tapioca flour)
  • condensed milk – the regular kind OR for dairy free used condensed coconut milk
  • brown sugar, oats and almond meal are the base of the crumble
  • add cinnamon, nutmeg and vanilla extract
  • butter (I used a dairy free version)

How to make Apple Crisp/Crumble in the Slow Cooker:

  • Peel and thinly slice the apples and toss with thickener
  • Pour sweetened condensed milk over the top
  • Use a fork to cut the butter together with the oats, brown sugar, almond flour, vanilla and spices
  • Sprinkle over the top of the apples in the slow cooker
  • Let cook for about 3 hours on high or 6 on low

Notes on this Recipe:

  • this will not brown up and become super crispy on top when making in the slow cooker
  • If it’s a bit watery, turn off the slow cooker and let it cool for around 30-60 minutes before serving
  • use mix of sweet and sour apples or sweet apples but don’t use all sour apples

What to Serve with Apple Crumble:

Apple crumble goes well with a scoop of ice cream or a simple dollop of whipped cream. I love Reddi Whip Almond Milk Whipped Cream for a dairy-free option.

More Slow Cooker Dessert Ideas:

Slow Cooker Apple Crumble pairs perfectly as a dessert with Slow Cooker Pulled Pork or Slow Cooker Sloppy Joes.

    My husband I didn’t care for this recipe. I didn’t understand the addition of sweetened condensed milk (“SCM”) since oven baked crumbles are just apples and topping. The SCM burned onto the sides of the crockpot, despite the spray I used. It was overly sweet, too.

    I would remake this recipe without coating the apples and minus the SCM. Just apples and topping. Thanks anyway for an interesting crock pot dessert.

  2. You have titled it “Apple Pear Crumble” but nowhere do I see “pear(s)” mentioned. Do you mean this recipe could use pears instead of apples?

    1. When I originally made this recipe I used a mix of both apples and pears. I recently remade it with just apples, but feel free to make it either way with similar results depending on what you prefer. Enjoy!
