Heat oven to 375°F. On cutting board, unroll dough; separate into 8 triangles. From center of 1 longest side to opposite point, cut each triangle in half, making 16 smaller triangles.
Place 1/2 teaspoon peanut butter on center of each triangle; top with 1/2 teaspoon jam. Bring corners to center over filling, overlapping ends; press gently to seal. Place on ungreased cookie sheet.
Brush each lightly with cream; sprinkle with sugar.
Bake 10 to 13 minutes or until golden brown.
