Instructions
 

Preparation

  • Preheat your oven to 180° C / 355° F (or 160° C / 320° F if using a fan setting) and line a 20 cm / 8 inch square tin with baking paper.
  • Place the vegan butter in the freezer for about 10 minutes.
  • Grate the chilled butter coarsely or cut it into small cubes, and combine it in a mixing bowl with the flour, cinnamon, cardamom, salt, baking powder, oats, and 150 g sugar.
  • Add the grated butter and use a pastry cutter to mix until it resembles coarse pebbles.
  • Press just under two-thirds of the crumble mixture into the base of the lined baking tin.

Baking

  • Bake the base in the preheated oven for 15 minutes.
  • In a medium-sized pot, combine the blackberries, 2 tbsp flour, lemon zest, lemon juice, 75 g sugar, and vanilla extract. Simmer gently until bubbling, about 1 minute, and then remove from heat.
  • Spread the blackberry filling evenly over the baked crust and sprinkle the remaining crumble mixture over the top.
  • Return to the oven and bake for an additional 30 minutes until golden brown and bubbling.

Cooling

  • Allow the bars to cool completely in the tin before slicing. For neater slices, refrigerate overnight.

Notes

Use fresh, ripe blackberries for the best flavor. You can also use nuts or different spices to customize the flavor.
