Ingredients Equipment Method Notes

Ingredients
  

  • 2 cups Rolled Oats (180g)
  • 1 cup Whole Wheat Flour (120g)
  • 1 1/2 tsp Baking Powder (6g)
  • 2 tsp Ground Cinnamon (5g), divided
  • 1/2 tsp Salt (3g)
  • 2 Large Eggs
  • 3/4 cup Pure Maple Syrup (180ml), plus more for drizzling
  • 1/2 cup Melted Coconut Oil (120ml)
  • 1/2 cup Plain Greek Yogurt (125g)
  • 1 tsp Vanilla Extract (5ml)
  • 2 medium Apples peeled, cored, and chopped
  • 1 medium Apple cored and thinly sliced
  • 1/3 cup Crushed Walnuts (40g)
  • 2 tbsp Whole Rolled Oats (15g)

Equipment

  • 1 9-inch round cake pan
  • 1 Large Mixing Bowl
  • 1 Medium Mixing Bowl

Method
 

  1. Preheat oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.
  2. In a large bowl, whisk together the 2 cups of rolled oats, whole wheat flour, baking powder, 1 1/2 tsp of the cinnamon, and salt.
  3. In a separate medium bowl, whisk together the eggs, 3/4 cup maple syrup, melted coconut oil, Greek yogurt, and vanilla extract until smooth.
  4. Pour the wet ingredients into the dry ingredients and gently fold with a spatula until just combined. Do not overmix. Fold in the chopped apples.
  5. Spread the batter evenly into the prepared pan. Arrange the thinly sliced apples on top in a layered pattern. Sprinkle with crushed walnuts, the 2 tbsp of whole rolled oats, and the remaining 1/2 tsp of cinnamon.
  6. Bake for 40-50 minutes, or until a wooden skewer inserted into the center comes out clean. The top should be golden brown.
  7. Let the cake cool in the pan for 15 minutes before transferring to a wire rack. Drizzle with additional maple syrup just before serving.

Notes

Choosing the Right Apples: Use firm, crisp apples like Honeycrisp, Gala, Braeburn, or Granny Smith for the best texture.
Don't Overmix the Batter: Mix only until just combined to ensure a tender, moist cake.
Toast Your Walnuts: For deeper flavor, toast the walnuts for 5-7 minutes at 350°F (175°C) before using.
