1. Preheat oven to 425°F. Grease 12 (2-1/2-inch) muffin cups.
2. Sift flour, baking powder and salt into large bowl. Stir in oat bran and brown sugar; set aside. In small bowl, combine milk, oil, eggs and vanilla. Stir milk mixture into dry ingredients just until moistened.
3. Cut cream cheese into 12 equal pieces. Spoon about 1/2 of batter into prepared muffin cups, filling about one-third full. Spoon about 1 tablespoon jam on top of batter. Top with 1 piece of cream cheese. Spoon remaining batter over jam and cheese, filling each muffin cup two-thirds full. Bake about 14 to 16 minutes or until browned.
