In a large bowl, combine flour, sugar, salt, and baking powder.
Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Gradually add milk, mixing until a dough forms. You may need slightly more or less milk.
Turn the dough out onto a floured surface and roll it out as thinly as possible, about 1/16-inch thick.
Use a knife or a special laufabrauð cutter to cut decorative patterns into the dough. Traditional patterns include circles or a combination of geometric designs.
Heat oil in a deep skillet or pot to 350°F (175°C).
Fry the bread pieces in batches, turning them until they are puffed and golden brown, about 1-2 minutes per side.
Remove from oil and drain on paper towels.
Let the laufabrauð cool completely before serving.
Enjoy your meal!
