Step 1

Beat egg yolks in a mixing bowl. Beat in sugar. Mix in remaining ingredients, using enough flour to make a soft dough. Don't overmix or overwork dough.

Step 2

On a floured surface, roll out dough into 1/2-inch thick. Use fattigmand cookie cutter to cut out cookie shapes.

Step 3

Carefully lift each cookie dough portion, and fold the sides of the dough into the slit in the center.

Step 4

Heat 2 inches of cooking oil in a large, heavy-bottomed pot until it reaches 370 degrees F. If you don't have a food thermometer, you can test to see if the oil is hot enough when you dip the edge of a cookie in the oil and it sizzles.

Step 5

Fry cookies until golden brown, using a slotted metal spoon to remove the cookies from the oil. The cookies fry pretty quickly - less than 1 minute, in my experience.

Step 6

Place fried cookies on a paper towel-lined pan to drain excess oil. Repeat with remaining dough.

Step 7

Dust cookies with powdered sugar when they are cool.
