Instructions

Preheat the oven to 400°F (200°C). Grease and line a 9-inch (23 cm) square pan with parchment paper. Leave an overhang of paper to use as a sling to lift the bars out.
For the shortbread-like dough, mix all the dry ingredients together. Incorporate softened butter with your finger tips until no lumps remain. Add the egg, and stir well until the dough comes together.
Pour half of the dough into the prepared pan and press flat into the base of the pan, using the palm of your hand, a glass or a measuring cup.
For the blueberry filling, combine blueberries with sugar, cornstarch, lemon juice and zest in a medium bowl and mix. Spoon the blueberry filling onto the crumble base and in the pan and level with the back of the spoon.
Scatter the remaining dough over the blueberry filling, flattening it slightly with your hand. Bake in the preheated oven for 20-25 minutes, or until the crumble is golden brown and the filling is oozing and bubbling. Remove from the oven and allow to cool completely until the filling has set. Use the paper sling to lift the bars out of the pan onto a chopping board, slice into squares, and serve!

Notes

* If using frozen blueberries, allow them to thaw, and pat dry with paper towels to remove the excess of juice. Then and only then, combine thawed and drained blueberries with the other filling ingredients.
