The remaining bakers have to try and bake without sugar, gluten or dairy this week. The signature challenge sees the bakers having to create a variety of sugar-free cakes, from an upside-down pineapple cake to carrot cakes. The technical challenge features gluten-free pittas. For their showstopper, the bakers have to make dairy-free ice cream rolls.
