Whisk eggs, sugar, honey, vanilla in a large bowl.
Add in the flour and baking powder until well combined but don't overmix, it makes the pancakes tough.
Leave the bowl in a cool place for 15 minutes. Don't stir the batter, you want the bubbles.
Preheat a flat frying pan or crepière, rub a little butter over the pan. Drop a spoonful directly downwards onto the pan, it should form a circle. Cook until golden brown then flip over. Repeat until the mixture is used up.
Once cooked, leave the Dorayaki on a cooling rack.
Press together in a sandwich (or sando as the Japanese call them) using your filling of choice.
