Ingredients
  

  • 2 small Honeycrisp apples (about 6 ounces each), divided
  • 2 cups old-fashioned rolled oats
  • 2 cups unsweetened soy milk
  • ¾ cup nonfat plain strained (Greek-style) yogurt
  • 4 tablespoons smooth natural peanut butter divided
  • 2 tablespoons pure maple syrup
  • 1 tablespoon vanilla extract
  • ¼ teaspoon salt
  • teaspoon ground cinnamon

Instructions
 

  • Chop 1 Honeycrisp apple into bite-sized pieces. Set aside.
  • In a medium mixing bowl, combine the rolled oats, soy milk, yogurt, 3 tablespoons of peanut butter, maple syrup, vanilla extract, salt, and cinnamon. Whisk well to combine.
  • Stir in the chopped apple pieces until evenly distributed. Cover the bowl with a lid or plastic wrap and refrigerate for at least 8 hours, or overnight, to let the oats thicken.
  • When ready to eat, portion the oats evenly into 4 (8-ounce) jars or bowls. Top each with an equal amount of the remaining 1 tablespoon of peanut butter (about ¾ teaspoon per serving).
  • Finely chop half of the remaining apple and sprinkle about 3 tablespoons over each bowl. Save the remaining apple half for another use.
  • Enjoy immediately, or cover and store in the fridge for up to 5 days for an easy grab-and-go breakfast option.

Notes

For extra creaminess, use whole-milk yogurt or add a splash of soy milk before serving. Customize your toppings with chopped nuts, seeds, or granola for added crunch.
