In a bowl, pour the flour, sugar, room temperature butter cut into small cubes and cinnamon.Using your fingertips, mix the ingredients without forming a ball. The mixture should be crumbly.Do not overwork the ingredients as the heat from your fingers will melt the butter. Preheat your oven to 180°C.

Bake for 20 to 30 minutes.
