  • 1 cup butter cut into small pieces
  • 1 cup brown sugar
  • 2 cups flour
  • 1 ½ teaspoons cinnamon
  • 1 cup oats


  • 1½ - 2 cups applesauce
  • 1 teaspoon ground cinnamon


  • Preheat oven to 325 degrees and spray a 9 x 13" baking dish with a non-stick spray .
  • In a food processor bowl, add butter, brown sugar and flour. Pulse until mixture forms small, pea sized crumbs. 
    1 cup butter, 1 cup brown sugar, 2 cups flour
  • Add cinnamon and oats. Pulse just until incorporated. 
    1 ½ teaspoons cinnamon, 1 cup oats
  • Place half the oat mixture into prepared baking dish. Press mixture down with your hands. 


  • In a small mixing bowl combine applesauce and cinnamon.
    1½ - 2 cups applesauce, 1 teaspoon ground cinnamon
  • Pour filling on top of oat mixture. Spread evenly over oat mixture.
  • Sprinkle remaining oat mixture over applesauce. 
  • Bake in a preheated 325 degree oven for 40 - 45 minutes.
  • Allow bars to fully cool before slicing into 12 equal pieces.


Tips for making
  • Use salted butter that is softened. The butter should be soft enough to spread easily on a slice of bread
  • Use old fashioned oats, which are a bit thicker than a quick oat. 
  • Some people prefer not quite as much applesauce filling. You can use 1 ½ cups instead of the 2 cups.
  • Allow bars to cool before slicing
  • Store any leftover bars in a covered container
If you don't have a food processor:
  • First, you can place the crust ingredients in a bowl and mix using a mixer with beaters. Make certain the butter is very soft, but not melted.
  • Second you could mix with your hands. Place ingredients in a bowl and use your hands or your fingers to mix. This may be a bit messy, but your hands are really a great kitchen tool. Simply use your fingers to mash butter into the flour and oat mixture.
