Introduction

These vegan Berry Crumble Bars are a delightful treat combining a crisp, buttery crumble base with a juicy, fruity filling. Perfect for a snack or dessert, they offer a harmonious balance of sweet and tart flavors with a satisfying texture.

The image shows nine square berry crumble bars arranged on brown parchment paper over a white marbled texture. Each bar has three visible layers: a golden crumbly oat topping with rough texture at the top, a thick, juicy dark red and purple berry filling in the middle that slightly oozes out on some bars, and a pale, firm crust base layer at the bottom. One bar near the top has been slightly lifted, showing the thickness and texture of the base along with the filling. The bars have uneven crumb pieces on top, and a few berry stains are visible on the parchment around the bars. photo taken with an iphone --ar 4:5 --v 7

Ingredients

150 g (1 2/3 cups) rolled porridge oats
180 g (1 1/2 cups) plain (all-purpose) flour
130 g (3/4 cup) light brown soft sugar
1/3 tsp baking powder
1/4 tsp salt
1/2 tsp cinnamon
175 g (2/3 cup) vegan butter or coconut oil, cubed
2 tsp cornflour (cornstarch)
1 Tbsp fresh lemon juice
150 g (5.3 oz) raspberry jam
400 g (14 oz) mixed fresh berries

Instructions

Step 1: Preheat the oven to 190°C (375°F/gas mark 5). Grease a 20cm (8-inch) square tin and line it with baking parchment.
Step 2: In a large bowl, mix together the oats, flour, baking powder, sugar, cinnamon, and salt.
Step 3: Add the vegan butter or coconut oil. Rub it in with your fingertips until the mixture resembles breadcrumbs.
Step 4: Tip about two thirds of the crumble mixture into the prepared tin. Spread it out evenly and press down very firmly.
Step 5: Bake for about 15 minutes until the edges are golden.
Step 6: To make the filling, mix the cornflour and lemon juice in a large bowl to form a paste. Stir in the raspberry jam, then fold in the mixed berries.
Step 7: Pour the filling over the baked base and spread it out evenly.
Step 8: Scatter the remaining crumble mixture on top. Bake for 25-30 minutes until the crumble is golden and the filling is bubbling.
Step 9: Allow the bars to cool in the tin. Once cooled, carefully lift them out using the baking parchment, cut into squares, and serve.
Step 10: Store any leftovers in the fridge.

Tips & Variations

Substitute the mixed fresh berries with frozen ones if fresh are not available—just add a few minutes to the baking time.
For extra crunch, sprinkle chopped nuts or seeds on top before baking.
Use your favorite seasonal fruits in place of berries to personalize the filling.

Storage

Store the bars in an airtight container in the refrigerator for up to 4 days. Reheat gently in a low oven if you prefer them warm, or enjoy cold straight from the fridge.

How to Serve

The image shows a stack of three square-shaped berry crumble bars on a white marbled surface, each bar having three layers. The bottom layer is a thick, crumbly golden-brown crust with a coarse texture. The middle layer is a glossy, juicy mix of dark red and purple berries that are slightly oozing out between the layers. The top layer is a golden, crumbly streusel topping with small clumps that contrast with the smooth berry filling. There are some crumbs and a bit of berry juice around the base of the stack, enhancing the rustic look. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use gluten-free flour for this recipe?

Yes, you can substitute plain gluten-free flour to make these bars gluten-free. Just ensure the oats are certified gluten-free as well.

How do I prevent the crumble from becoming soggy?

Pressing the base firmly before the first bake helps create a sturdy foundation. Also, baking the base partially before adding the filling ensures it stays crisp.
