2 (8 ounce) packages cream cheese, at room temperature 1/4 cup sour cream 1/2 onion, minced 1 tablespoon garlic powder 2 tablespoons white sugar, or to taste 1 pound crab meat 1 (14 ounce) package wonton wrappers
Preheat oven to 350 degrees F (175 degrees C). Grease a baking sheet, and set aside. Combine the cream cheese, sour cream, onion, garlic powder, and sugar in a bowl, and beat until soft and well mixed. Lightly stir in the flaked imitation crab meat. Fill a bowl with lukewarm water. Remove a wonton wrapper from the stack, and cover the stack with a damp paper towel to keep the wrappers from drying out. With your finger, wet two adjoining edges of the wrapper with water, and place about 2 teaspoons of filling in the center. Fold the wrapper into a triangle shape, pressing out all the air and sealing the edges well. Place the filled wonton on the prepared baking sheet while you finish filling and folding the wontons. Bake in the preheated oven for about 15 minutes, until the wonton edges turn brown and crisp. Serve immediately.
