Blueberry Crumble Squares

Method

1. Preheat the oven to 180°C / 356° fan. Next line a baking tin (ours is roughly 9” x 13”) with baking paper across the base and fully up the sides so you can easily pull out the squares later using the baking paper. Then brush the baking paper with a touch of oil.
2. Combine the buckwheat flour, plain flour, light brown sugar, baking powder and cinnamon in a large mixing bowl. Then add the plant-based margarine and rub the margarine into the dry ingredients using your fingertips until you get a crumb like consistency.
3. Next, for the blueberry compote pop the blueberries in a saucepan on a medium heat, followed by the light brown sugar and lemon zest. Simmer for 6 - 8 minutes until some of the water has evaporated. Next add the cornflour to a small bowl and combine it with 2 tablespoons of water until smooth. Then add the cornflour mixture to the saucepan and simmer for 1-2 minutes or until the compote has thickened.
4. Add three quarters of the crumb to the baking tin and press it down with your fingers to make sure it is compact. Then evenly pour the blueberry compote over the top and sprinkle the remaining crumb all over to finish. Bake for 25 - 35 minutes or until the crumb is golden brown.
5. Leave to cool fully in the tin then gently pull the crumble out using the baking paper and pop it onto a chopping board and slice into 15 squares.
