Pre-heat oven to 200 degrees C (400 degrees F). Combine all dry ingredients in a large bowl (not the butter or strawberries). Add the melted butter and stir to combine, then use your hands to make sure its all incorporated. The mixture should form a large ball when you press it together. (If it is crumbling apart you may need a little more butter).

Take 3/4 of the mixture and press into a slice tray sized 25cm x 18cm, lined with baking paper. Press down really firmly with your hands.

Wash and slice the strawberries. Place on top of your slice and then take the remaining mixture and sprinkle over the top. Press down with your hands again. Its fine if there are strawberries poking though the mixture. Bake for 30-35 minters or until lovely and golden. Allow to cool on the bench and then place in the fridge. Slice and serve.
