Bake the biscuit in the oven preheated to 180 C for 40 minutes. During baking, do not open the oven for the first 25 minutes, as sponge can fall from the temperature drop. Baking times can vary significantly, as everyone's ovens are different, so be sure to check your readiness with a wooden skewer. Stick the skewer in the middle of the biscuit and immediately remove: if it is dry, then the biscuit is ready.
