In medium mixing bowl beat eggs; set aside. Drain both cans of apples or blueberries from muffin mixes; add to beaten eggs. Stir in flour and dry muffin mixes. On well floured pastry sheet roll out dough to 1/2" thickness. Cut out donuts with a floured 2 1/2" diameter donut cutter, pressing straight down.
Meanwhile, in a large saucepan or deep fat fryer heat cooking oil to 375 degrees. Fry the donuts and holes, a few at a time, for 1 to 1 1/2 minutes or until golden brown, turning several times. Drain on paper toweling. If desired, sprinkle powdered sugar over tops of rolls in granulated sugar or cinnamon sugar. Makes 16 donuts.
1/2 c. packed brown sugar
1 1/4 tsp. ground cinnamon
Combine.
