Separate the eggs and beat the egg whites until stiff. Put the flour, the egg yolks, baking powder, salt, milk and honey in a bowl and mix with an electric hand mixer to form a homogeneous dough. Let rest 30 minutes. Fold raisins with the beaten egg whites into the batter.
To bake, melt a little butter in a pan. Pour in a tablespoon each of batter and cook on each side in portions until golden brown, 1-2 minutes. Remove and keep warm (for example in an oven at 80°C, approximately 175°F) until the batter is used up.
To serve, drizzle with maple syrup or top with whipped cream.
