Instructions

  1. Preheat the oven to 350℉.
  2. Line two 9"x13" baking dishes with parchment paper and spray with nonstick cooking spray. Set aside.
  3. Add 1¼ Cups of butter, brown sugar, and sugar to a large mixing bowl. Beat with a hand mixer until light and creamy.
  4. Add 1 teaspoon of vanilla and eggs and beat until completely combined.
  5. Add the flour, cinnamon, salt, and baking soda to a large mixing bowl and stir.
  6. Add the flour mixture to the brown sugar mixture and beat until everything is mixed together.
  7. Add the quick oats and the old-fashioned oats and beat the mixture again.
  8. Scoop half the mixture into one of the lined 9"x13" baking dishes. Add the other half of the mixture to the other 9"x13" baking dish.
  9. Spray your hands with nonstick cooking spray and flatten the dough with your hands. Spread the dough evenly out to the corners of each dish.
  10. Bake at 350℉ for 13 minutes or until golden brown.
  11. While waiting for the bars to cool, make the cream. Add the ¾ cup butter to a large bowl and beat with a hand mixer until light and creamy.

  16. Place in the freezer for at least 1 hour.
  17. Take out of the freezer and slice into bars.
