  • 1 tablespoon honey
  • 1 teaspoon baking powder
  • ½ cup white granulated sugar
  • ½ tablespoon ground cinnamon
  • ¾ cup chopped walnuts

Instructions
 

  • Preheat your oven to 350°F and coat an 8x8 inch glass baking dish with butter or nonstick cooking spray.

    2 large eggs, ½ cup whole milk, ¼ cup applesauce, 1 teaspoon vanilla extract, 1 tablespoon honey
  • Add the baking powder, sugar, cinnamon, walnuts, cranberries, and oats to the mixing bowl. Fold the ingredients together until the wet and dry ingredients are fully combined.
    1 teaspoon baking powder, ½ cup white granulated sugar, ½ tablespoon ground cinnamon, ¾ cup chopped walnuts, ¾ cup dried cranberries, 2 ½ cups old fashioned oats
  • Transfer the oat mixture to the prepared dish and bake for 25 minutes.
  • Allow the dish to come to room temperature before slicing into bars.

Notes

Nut Variations: Any type of nut can replace the walnuts—almonds and pecans are excellent alternatives that add their own distinct flavor.
Flavor Additions: Swap the applesauce with peanut butter for a richer taste, or fold in ¾ cup chocolate chips for a sweeter variation.
Oat Types: Quick oats can be substituted for old fashioned oats, though the bars will have a softer texture with less chew.
Dried Fruit Options: Raisins work just as well as cranberries in this recipe for a different flavor profile.
Nut-Free Version: Replace walnuts with sunflower seeds or pepitas for a school-safe option that's equally nutritious.
