Ingredients

  • 1 cup old-fashioned oats
  • 1 cup all-purpose flour
  • ¼ cup brown sugar
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • 1 large egg
  • ½ cup coconut oil, melted
  • 2 cups apples, diced
  • 1 teaspoon vanilla extract
  • 1 tablespoon lemon juice
  • 1 teaspoon ground nutmeg
  • 2 tablespoons water
  • 1 tablespoon maple syrup
  • 1 tablespoon chia seeds

Instructions

  • Begin the recipe by preheating the oven to 350 degrees F. and line a square baking pan with parchment paper and set aside.
  • Using a food processor, pulse together 1 cup old fashioned oats, 1 cup all-purpose flour, ¼ cup brown sugar, 1 teaspoon baking powder, 1 teaspoon ground cinnamon, ¼ teaspoon salt, 1 large egg, and ½ cup melted coconut oil until it forms a crumbly but sticky mixture.
  • Set aside ⅓ of the mixture to use for the topping. Add the rest of the mixture into the prepared parchment-lined baking pan and press evenly into the bottom of the pan.
  • In a small saucepan over medium heat, add the 2 cups diced apples, 1 teaspoon vanilla extract, 1 tablespoon lemon juice, 1 teaspoon ground nutmeg, 2 tablespoons water, and 1 tablespoon maple syrup until heated and the sauce is warm.
  • Stir 1 tablespoon chia seeds into the apple mixture and cook for an additional 5 minutes. Pour the mixture onto the crust mixture in the baking dish and spread in an even layer. 
  • Sprinkle the reserved ⅓ topping that you set aside on top of the apple mixture evenly.
  • Place into the oven and bake for 30 minutes or until the top has lightly browned.
  • Carefully remove from the oven and allow the bars to cool in the baking dish for 10 minutes before transferring to a cooling rack to cool completely. Slice into bars and serve. 
  • Store the extra in an airtight container for up to 5 days at room temperature or in the refrigerator.

Notes

  • May substitute gluten-free flour for all-purpose flour in the same unit of measure. 
  • May use gluten-free oats. 
  • Use old-fashioned oats or rolled oats, but not steel-cut oats. 
  • Allow the bars to cool completely before cutting into squares.
