In a deep-fryer, heat oil to 375 degrees F.
Cover the bottom of a funnel with your finger. Ladle 1/2 cup of batter into funnel. Holding funnel over oil, slowly release finger and move in a spiral motion, then cross over to create criss-cross pattern. Fry golden on both sides, about 2 to 3 minutes per side. Drain on paper towels and dust with confectioners' sugar.
Alternate method: Instead of using a funnel, try squeezing batter out of a plastic ketchup bottle. This can help you make the design more accurate and is also less messy.
