Step‑by‑Step Instructions for Vegan Berry Crumble Bars
Step 1: Preheat and Prepare
Start by preheating your oven to 190°C (375°F) while you prepare a 20cm (8in) square tin. Line the tin with parchment paper, ensuring it hangs over the edges for easy removal later. This will set the stage for creating the perfect Vegan Berry Crumble Bars, so get that oven nice and warm!
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine rolled porridge oats, plain flour, baking powder, light brown soft sugar, cinnamon, and a pinch of salt. Stir these dry ingredients well until they are evenly mixed. This blend creates the base and topping for your crumble bars, ensuring a lovely, balanced flavor that pairs beautifully with the berries.
Step 3: Incorporate the Vegan Butter
Next, rub in the vegan butter or coconut oil into your dry mixture using your fingertips. Continue until the mixture resembles coarse breadcrumbs with small clumps. This step is crucial for achieving that delightful crumbly texture that makes Vegan Berry Crumble Bars so wonderful.
Step 4: Bake the Base
Take about two-thirds of your crumble mixture and press it firmly into the bottom of your prepared tin. Make sure it’s evenly spread and packed down. Bake this base in your preheated oven for about 15 minutes, or until it turns a lovely golden brown—this will create a sturdy foundation for your berry filling.
Step 5: Prepare the Berry Filling
While the base is baking, prepare the filling. In a small bowl, mix the cornflour (cornstarch) with fresh lemon juice to form a paste. Once combined, add your raspberry jam and the choice of mixed fresh berries. Stir until the fruit is well coated, creating a luscious mixture that bursts with flavor.
Step 6: Assemble the Bars
Once the base is golden, remove it from the oven and spread the berry mixture evenly over the top. This vibrant layer is essential for the delightful juiciness of your Vegan Berry Crumble Bars, so make sure to cover the base thoroughly. After that, sprinkle the remaining crumble mixture generously over the berries, ensuring an even coverage.
Step 7: Bake to Perfection
Return the assembled dish to the oven and bake for an additional 25 to 30 minutes. You’ll know it’s done when the crumble on top turns golden brown and the berry filling begins to bubble—this is the moment you’ve been waiting for, bringing the delicious aroma of berries into your kitchen!
Step 8: Cool and Serve
Once baked, remove the tin from the oven and allow it to cool completely in the tin. This step is important for the bars to set properly. Once cool, lift them out using the parchment paper and cut them into squares. Enjoy your delightful Vegan Berry Crumble Bars either warm or at room temperature!

Vegan Berry Crumble Bars Recipe FAQs
What berries should I use for the best flavor?
Absolutely! Opt for ripe, seasonal berries like raspberries, blackberries, blueberries, or strawberries for a vibrant flavor in your Vegan Berry Crumble Bars. Freshness is key, so look for berries that are plump and free of dark spots. If you can’t find fresh berries, thaw frozen varieties, but remember to drain any excess liquid to avoid a soggy filling.
How do I store Vegan Berry Crumble Bars?

What should I do if my crumble mixture is too dry?
If your crumble mixture seems too dry, try adding a tablespoon of vegan butter or coconut oil at a time until it holds together better. You want it to resemble coarse breadcrumbs with some clumps without being too wet. This will ensure you achieve that perfect texture for your Vegan Berry Crumble Bars.
Are there any dietary considerations I should keep in mind?
Definitely! These bars are vegan, but always check jam labels for added sugars or unwanted ingredients.
