    Berry crumble bars - make the best of summer berries with these easy to make, jammy, oaty, vegan crumble bars. Perfect for snacking on!

    A stack of three vegan berry crumble bars.

    Summer is nearly over already so we had better make good use of those lovely summer berries while we still can! These vegan berry crumble bars are a delicious way to use up a selection of berries and they are perfect for dessert or snacking on.

    These vegan berry crumble bars consist of a chewy, oaty biscuit base which is filled with mixed fresh berries and raspberry jam and is topped with more oat cookie crumbs.

    The base and topping are made with the same mixture so you don't need to make a separate mix for the top. The berries are sweetened just with the jam - no extra sugar; so they retain some of their sharpness which is delicious with the buttery crumble topping.

    You can vary the berries that you use to suit - I used a mixture of raspberries, blackberries and blueberries, but strawberries and cherries would also work well.

    You can also use whatever flavour jam you like, I used a naturally sweetened raspberry jam (St Dalfour); but just use whatever jam you like best.

    The bars are best eaten on the day they are made but they will keep in the fridge for a few days.

    How To Make Berry Crumble Bars:

    (For ingredients and full instructions see the recipe card below)

    *For the best results make sure that you follow the recipe closely. As always, I highly recommend using the gram measurements (with a digital scale), rather than the cup conversions. Cup measurements are simply not accurate enough for baking and I cannot guarantee the best results if you use them.*

    Start by mixing together oats, flour, baking powder, brown sugar and cinnamon. Then you add some vegan spread or coconut oil and rub it in until the mixture resembles breadcrumbs.

    step 1 - making the crumble

    Tip about two thirds of the mixture into a square tin and pack it down firmly then bake until golden.

    step 2 - baking the base

    To make the filling, mix together some cornflour with lemon juice then stir in raspberry jam followed by fresh berries. Spread the filling over the cooked base.

    step 3 - making the filling

    Scatter over the rest of the crumble mixture then bake until golden and bubbling.

    step 4 - baking the bars

    Ingredients

    Crumble:

    • 150 g (1 ⅔ cups) rolled porridge oats
    • 180 g (1 ½ cups) plain (all-purpose) flour
    • 130 g (¾ cup) light brown soft sugar
    • ⅓ tsp baking powder
    • ¼ tsp salt
    • ½ tsp cinnamon
    • 175 g (⅔ cup) vegan butter or coconut oil cubed

    Filling:

    • 2 tsp cornflour (cornstarch)
    • 1 Tbsp fresh lemon juice
    • 150 g (5.3 oz) raspberry jam
    • 400 g (14oz) mixed fresh berries

    Instructions

    • Preheat the oven to 190C/375F/gas mark 5. Grease a 20cm/8in square tin and line with baking parchment.
    • Mix together the oats, flour, baking powder, sugar, cinnamon and salt in a large bowl.
    • Add the vegan butter or coconut oil and rub in using your fingertips until the mixture resembles breadcrumbs.
    • Tip about two thirds of the mixture into the prepared tin. Spread it out level and pack it down very firmly.
    • Bake for about 15 minutes until golden around the edges.
    • To make the filling, mix the cornflour and lemon juice together in a large bowl to make a paste. Stir in the jam followed by the berries.
    • Tip the filling over the base and spread level.
    • Scatter over the remaining crumble mixture. Bake for 25-30 minutes until the crumble is golden and the filling is bubbling.
    • Leave to cool in the tin then carefully lift it out using the baking parchment, cut into squares and serve.
    • Store any leftovers in the fridge.

      Delicious recipe, perfect amount of sweetness and slightly tart from the berries. The base turned out great, I added walnuts on top for extra crunch! Highly recommend

      Do you think this would work with thawed frozen berries? Frozen is all I have in the house!

        Hi Molly, I think they would be ok. I would probably drain off the excess liquid once they are defrosted to stop the bars becoming soggy.

        I used frozen and they were perfect even with the juice! I also didn"t bake the bottom first. Good luck

      Oh my god these are SOOOO good! East to make, came out perfect, hold together really (unlike some crumbly recipes that end up everywhere!) and easy ingredients. I've eaten them for breakfast and lunch and dessert 😉 These are definitely on my regular rotation now. Thank you Hannah!

      These turned out amazing. I used quick oats and only 1/3 cup coconut palm sugar for the base. I thawed out frozen berries and drained the excess liquid and added Crofters organic black currant jam and 1tbs of chia seeds. Will definitely be making again!

        Hi Kristie, I haven't tried but I don't see why not. 3 months is the general rule for freezing things.
