Preheat the oven to 200°C/400°F/gas mark 6 (or fan oven 180°C/350°F/gas mark 4). Cut a sheet of baking paper to fit on a baking tray or lightly grease the tray with a little vegan butter.
Remove the stalks from the strawberries and cut the strawberries into small pieces using a table knife.
Tip the flour and baking powder into a big bowl and stir to mix. Cut the cold vegan butter into small pieces and using your fingertips rub the butter in to the flour to make fine breadcrumbs. Try to only use your fingertips so that you don’t melt the butter.
Add the chopped strawberries to the flour mixture and stir gently. Measure the milk in a measuring jug, add the agave syrup and vanilla and stir to mix. Pour the milk into the flour mixture and stir together with a table knife.
Use your hands to mix into a big ball and then on a lighly floured surface gently flatten to make a circle of dough. Mark into triangles using a table knife – cut in half and then half again, and then cut each quarter in half to make 8 triangles. Separate the triangles.
Brush each scone with a little milk using your finger (or a pastry brush if you have one), put onto the trays and bake for 12-15 minutes or until risen and golden.
