    Vegan Raspberry Crumble Oatmeal Bars

    Jump to Recipe Jump to Video Print Recipe

    If you love the sound of a delicious traybake-style raspberry slice, you'll love these easy vegan raspberry bars which are made from oatmeal, crumble and a sweet raspberry filling. Once your base has been prepared, these easy snacks take less than 30 minutes to bake inside the oven.

    For me, these bring back a lot of warm nostalgia and the fact that they're easy to make, only enhances the experience!

    These raspberry-filled bars make a great late night supper with custard and are best served warm. Who wants a slice? The oatmeal is beautifully golden and crumbly which compliments the juicy, sweet filling greatly.

    If homely, comforting treats are your thing, I highly recommend that you try a selection of my other nostalgic baking recipes such as, my vegan pudding cake, vegan sticky toffee pudding & vegan double chocolate pudding pie recipes.

    Why You Will Love These Bars

    • Great Texture - They are crumbly and so soft. The gooey jam in the center completes what is an all-round, delicious consistency. In many ways they're like my vegan raspberry coconut slices.
    • Versatile - These bars can totally be eaten on their own or alternatively, alongside other things like custard and vegan coconut whipped cream!
    • Easy to Make - Once you have made the simple base, you only need to make the jam filling and bake. They're ready in no time.
    • Visually Appealing - The bars have a gorgeous radiance to them, as well as being filled with a bright red raspberry jelly.
    • Allergy Friendly & Plant Based - These bars are fully vegan and dairy free.

    Ingredient Notes

    The ingredients needed to make this vegan raspberry bars recipe laid out neatly on a white marble background.
    • Instant oats - These make a great addition to the streusel.
    • Vegan butter - Make sure that this is at room temperature when you use it or else the crumble won't have the right consistency. This vegan butter always works well for a crumble, as it did for my vegan blueberry cream cheese muffins, vegan apple oatmeal cake and vegan cherry crumble cake recipes.
    • Cornstarch - This makes a great thickener for the filling. The jam always tastes better when it isn't thin and runny.
    • Raspberry jelly - I personally prefer seedless jam but if you like a seeded variety then that is not an issue at all. Store-bought jam is perfectly fine for this recipe.
    • Raspberries - This recipe calls for fresh raspberries but if you only have frozen ones at hand, they are okay to use.

    See recipe card for full information on individual ingredients and quantities.

    Substitutions & Variations

    • Raspberry flavors aren't for everyone, so it is completely fine if you would like to change the flavor of the fillings. Perhaps you could try a blueberry jelly, strawberry or maybe even blackberry? It's completely your call.
    • You can make these bars Gluten Free by using a Gluten Free, 1:1 all-purpose flour, instead of regular white flour. Instant oats are often naturally Gluten Free but check to make sure. I haven't tested this, so if you decide to make this customisation, I hope they turn out well for you. I also gave this option in my vegan caramel slices recipe and they taste amazing Gluten Free.

    How To Make Raspberry Crumble Bars

    For the full method, please refer to the recipe card at the bottom of this post.

    A lined square baking tin.

    1: Line a large, square cake tin with parchment paper.

    The crumble mixture combined inside a large bowl.

    2: Make the crumble mixture.

    The crumble mixture is pressed into the lined tin.

    3: Press the crumble base into the prepared tin. Bake.

    The cornstarch and lemon juice is mixed together inside another mixing bowl.

    4: Make the cornstarch mixture.

    The remaining filling ingredients have been added to the bowl, including the raspberries.

    5: Add the remaining filling ingredients to the bowl.

    The base as been baked and is cooling.

    6: Let the base cool fully.

    The filling for my vegan raspberry bars has been poured onto the base.

    7: Pour the filling over the base.

    Extra crumble has been crumbled onto the base.

    8: Sprinkle the remaining crumble over the filling. Bake.

    The bars have been baked and are golden brown.

    9: Let the bars cool completely.

    Expert Tips

    Let the freshly baked bars set - Once the bars are baked and have left the oven, it is tempting to slice straight away. However, they take quite a while to cool. Let them cool fully so that they can set and then you can slice. The filling will have thickened more by this point.

    Use frozen raspberries - Although, this recipe calls for fresh raspberries, you can totally use frozen ones instead. Choose which you prefer.

    Recipe FAQs

    Why do I need to let the bars cool?

    This is because, the filling will thicken during the cooling process, making the bars much easier to slice afterwards. Slicing too early will mean that they're still a little warm but they'll also be very messy and difficult to manage.

    How should I store these bars?

    Store these vegan raspberry bars inside the fridge for up to 7 days. Also make sure that they're inside an airtight container.

    Can I make these slices Gluten Free?

    Yes, replace the flour with Gluten Free all-purpose 1:1 flour and make sure that your oats are also suitable.

    Ingredients

    For the crumble:

    • 200 g all-purpose flour
    • 135 g instant oats
    • 140 g light brown sugar
    • 0.5 teaspoon baking powder
    • 0.5 teaspoon ground cinnamon
    • 0.25 teaspoon salt
    • 180 g vegan butter cubed, room temperature

    For the raspberry filling:

    • 3.5 teaspoons cornstarch
    • 1.5 Tablespoons fresh lemon juice
    • 0.5 teaspoon almond extract
    • 0.5 teaspoon vanilla extract
    • 120 g sweetened raspberry jam jelly
    • 300 g fresh raspberries
    US Customary - Metric

    Instructions

    Make the crumble:

    • Preheat the oven to 180 Celsius (356F). Also grease and line an 8x8 inch, square baking tin with parchment paper. Set aside.
    • To a large mixing bowl, add the flour, oats, sugar, baking powder, cinnamon and salt. Mix well.
    • Next add the vegan butter to the mixture. Use your hands to rub the butter into the dry ingredients until the mixture is crumbly and has the texture of breadcrumbs.
    • Press two-thirds of your crumble mixture into the base of the lined baking tin firmly. You can use the bottom of a flat glass to pack it in tightly.
    • Bake the base inside the pre-heated oven for 12 minutes. It should be slightly golden. Place the rest of the crumble in the fridge for now.

    Make the raspberry filling:

    • While the crumble base is in the oven, make the filling. To a large bowl, add the cornstarch and lemon juice and mix to form a paste. Next, mix in the almond extract, vanilla extract and jam. When the ingredients are combined, finally fold in the fresh raspberries.
    • Pour the raspberry mixture over the crumble base. Make sure that it is level then sprinkle on the rest of the crumble for the topping.

    Bake the bars:

    • Bake in the center of your oven for 25 minutes. The topping should be golden brown, and the filling should be bubbling a little around the edges.
    • Let the crumble oatmeal bars cool at room temperature for 75 minutes. The filling will also thicken more. Slice and serve.

    Notes

    • Once the bars are baked and have left the oven, it is tempting to slice straight away. However, they take quite a while to cool. Let them cool fully so that they can set and then you can slice. The filling will have thickened more by this point.

      I don’t have vegan butter, can I replace it with olive oil?

        Hi! Unfortunately, the vegan butter is a very important binding ingredient for this recipe. I haven't tested olive oil and I can't imagine that it'll have a good effect.

      I've just made this, the only change is I took a mix of berries instead of just raspberries and it's FANTASTIC and so easy to do.
      I didn't have the patience to wait 75 minutes and I actually like it warm.
      Amazing, thank you so much for the recipe.
