Preheat the oven to 180 degrees Celsius, then line a baking pan or tray with parchment paper. Pour the mixture into it. Place in the oven and bake for 25 minutes.
Every oven is different, so baking time may vary. Use a wooden skewer to check whether the cake is ready or not. Insert it into the cake and remove it. If the skewer is dry, the cake is ready.
