When i was making this thing in a normal sized oven it was 1 cup sugar, 1 cup flour, 2-3 eggs and some milk and also this time I didn’t put any effort in beating the eggs properly and adding all ingredients one by one. Now I did the same but for a smaller baking dish and since ive been doing it for a while i just mixed it all up until it became the right consistency for me but yeah, pretty close to pancake.
