Ingredients

  • 1/2  cup  unsalted butter room temperature
  • 1 cup creamy peanut butter
  • 3/4  cup  dark brown sugar packed
  • tablespoon  vanilla extract

  • 1 1/2  cups  old fashioned oats left whole
  • 1/2  teaspoon  baking soda
  • 1/2  teaspoon  salt

Notes

*Make ground oats by placing about 2 cups old fashioned oats in your food processor. Grind until the oats resemble flour. Measure out 1 and 1/4 cups ground oats and resume with recipe!
