Preheat oven to 375 degrees. Unroll dough and press all seams to seal on ungreased cookie sheet.
Cut slits at 1 inch intervals down both long sides of dough.

Mix cream cheese and sugar together. Spread down the center of dough. Top with blueberries. Start with the left side and start braiding the dough with the cut slits.

Bake 12 to 14 minutes or until golden brown. Sprinkle with powdered sugar just before serving.
