Ans: First, you need to grease the pan with some oil using a pastry brush and dust some flour on it. Alternatively, a baking spray that doesn't have lecithin in it can also be used. Then, slowly pour the batter using a spoon to avoid bubble formation. Tap it thrice to make sure any trapped bubbles are completely released. This will help the batter to perfectly reach all crevices for evenly baking the cake without any air bubbles.
