Mix the dry ingredients in a bowl
Use a hand mixer and add around ½ of the milk. This way you will be able to avoid lumps of flour in the batter.
Once the batter is evenly mixed then add the rest of the milk and then add the eggs.
Add the same amount of bread slices you can fit in your pan to the pancake batter and let it soak a few minutes (how long depends on the bread)
Fry the soaked breads in some butter until they have a nice golden brown on each side
At the same time you start frying you should add some more bread slices to the batter for soaking while you fry.
Serve hot with same topping as you would with pancakes. The typical Swedish topping is strawberry jam and whipped cream but any jam would do. Lemon juice with sugar is also quite popular. Or just fresh fruits or berries.
