This is a recipe video for fluffy castella pancakes that can be made with just four ingredients using a skillet from Daiso. The batter is made by mixing egg yolks, soy milk, and pancake mix, and then combining it with a meringue made from egg whites and brown sugar. The mixture is then poured into a skillet that has been lightly greased. Bake in the oven in two stages to create pancakes with a light and fluffy texture. Serve with butter or maple syrup to your liking, and it's the perfect treat for a café experience at home.
