Ingredients

Scale
  • 2 cups (180g) rolled oats
  • 1 cup (120g) oat flour
  • 2 medium apples (about 300g), grated or finely chopped
  • 2 large eggs
  • 1/3 cup (80ml) pure maple syrup
  • 1/2 cup (120g) unsweetened applesauce
  • 1/4 cup (60ml) milk (any kind)
  • 2 tbsp (30ml) melted coconut oil
  • 1 tsp vanilla extract
  • 1 1/2 tsp cinnamon
  • 1 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup (60g) chopped walnuts or pecans (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides.
  2. Wash and core the apples. Grate them on the large holes of a box grater (skin on) or dice into 1/4-inch cubes. You should have about 1 1/2 cups.
  3. In a large mixing bowl, combine the grated apples, eggs, maple syrup, applesauce, milk, melted coconut oil, and vanilla extract. Whisk until well combined.
  4. Add the rolled oats, oat flour, cinnamon, baking powder, baking soda, and salt to the wet mixture. If using nuts, add them now. Stir with a spatula until just combined (do not overmix).
  5. Let the batter rest for 5 minutes to allow the oats to absorb liquid.
  6. Pour the batter into the prepared pan and spread into an even layer.
  7. Bake on the middle rack for 30-35 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  8. Cool in the pan for 10 minutes, then lift out using the parchment overhang and transfer to a cooling rack. Cool completely before slicing.

Notes

Let the batter rest for 5 minutes before baking for a more tender texture. Grate apples instead of dicing for even distribution. Use room temperature eggs to prevent coconut oil from solidifying. Check oven temperature with an oven thermometer for accuracy.
