    Slow Cooker Raspberry Crumble

    Here is my easy recipe for Slow Cooker Raspberry Crumble! All made in one pot, great for cold weather.

    White bowl of raspberry crumble.

    Although the summer term at school has now started, there was still a little chill in the air this morning when I took my eldest daughter to school.

    So, as I thought she might get a bit cold wearing just ankle socks and no tights, a warming dessert was in order after dinner!

    I love an apple crumble and thought I could make it more spring-like by adding in some raspberries.

    As usual, I used my slow cooker, as I find it very convenient to be able to put your food in and go off and do other things until it is ready.

    I hadn’t made a crumble in the slow cooker before but had heard it was possible so thought I would give it a go.

    I was pleased to see that the top did go crunchy on top as it does in the conventional oven.

    It tasted great so I will definitely be doing this again (hopefully in autumn though!).

    Ingredients

    Get the quantities in the recipe card below (scroll further down)

    • flour – plain (all purpose) for crumbles, as you don’t want it to rise.
    • butter
    • sugar – caster (superfine) –  to sweeten the crumble topping and a little to sweeten the fruit.
    • oats (oatmeal) – I use porridge oats.
    • cooking apples
    • raspberries 

    Method 

    1. Make the crumble first; sift the flour into a bowl, rub in the butter to the consistency of medium breadcrumbs, then stir in the sugar and oats.
    2. Prepare the fruit and place it in the slow cooker. Chopped apple and raspberries in slow cooker pot.
    3. Tip in the sugar for the fruit and give it a stir. Spray the sides of the slow cooker bowl where the crumble will be with some cooking mist (or oil spray), to prevent sticking. 
    4. Finally, tip the crumble mixture over the fruit and press it down lightly. Crumble assembled in slow cooker.
    5. Now switch the slow cooker on to high, place a clean tea towel under the lid to stop water dripping onto the crumble, and cook on high for 2 hours.
    6. After two hours, place the lid ajar and cook for another 30 mins to an hour until the crumble firms up and starts to go crispy around the edges.Serve and enjoy! Bowl of slow cooker raspberry crumble, served.

    The crumble starts to crisp up and isn’t soggy at all as you might worry from cooking it in a slow cooker.

    With all the slow cooker baking I do I had no doubts in my mind!

    I am linking this recipe up with the Slow Cooked Challenge hosted by Janice from Farmersgirl Kitchen. Every month you’ll find bloggers there linking up their tasty slow cooked recipes. Do go over and have a look, I always find inspirational dishes in Janice’s linkup.

    I am also linking up with Credit Crunch Munch from Fuss Free Flavours and Fab Food 4 All, hosted this month by Michelle from Utterly Scrummy Food for Families. I used up the end of a bag of porridge oats and a bag of plain flour for this recipe (hurray!) and also use the slow cooker as a cheaper means of cooking.

      That is so useful to know that the top will crisp up if you open the lid a little. You really are the slow cooker queen. Thanks for linking to Credit Crunch Munch!

      Thanks for linking to me lovely lady 🙂 This again looks divine. I love crumbles and although I sometimes make the filling in a slow cooker I never try the whole job so will give it a go.

      That looks delicious, I use the slow cooker to make crumbles too. I have never put raspberries in with apples though and will definitely have to try it before it gets too warm. Thank you for sharing x
