Ingredients
  

  • 2 cups Old-Fashioned Rolled Oats (180g)
  • 1 cup Whole Wheat Flour (120g)
  • 2 large Eggs
  • 1 cup Unsweetened Almond Milk (240ml)
  • 1/2 cup Maple Syrup (120ml)
  • 1/4 cup Melted Coconut Oil (60ml)
  • 1 1/2 tsp Baking Powder (7.5g)
  • 1 tsp Vanilla Extract (5ml)
  • 1/2 tsp Salt (2.5g)
  • 3 medium Apples (like Honeycrisp or Gala) 2 diced, 1 thinly sliced
  • 2 tbsp Brown Sugar or Coconut Sugar (30g)
  • 1 tbsp Ground Cinnamon (15g), divided
  • 1/4 cup Crushed Toasted Walnuts (30g), for garnish
  • 2 tbsp Maple Syrup (30ml), for drizzle

Equipment

  • 1 9-inch round cake pan
  • 2 Mixing Bowls

Instructions
 

  1. Preheat your 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 rolled oats, whole wheat flour, baking powder, 1/2 tbsp of cinnamon, and salt.
  3. In a separate bowl, whisk the eggs, then mix in almond milk, 1/2 cup of maple syrup, melted coconut oil, and vanilla extract.
  4. Pour the wet ingredients into the dry and gently fold until just combined. Fold in 2 peeled and diced apples.
  5. Spread the batter evenly in the prepared pan. Arrange the thinly sliced apple from the remaining apple over the top in a fanned, overlapping pattern after tossing it with brown sugar and the remaining cinnamon. Add a final dusting of cinnamon.
  6. Bake for 40-50 minutes, or until a toothpick comes out clean and the apple edges are caramelized and slightly charred.
  7. Let the cake cool in the pan for 15 minutes before transferring to a wire rack to cool completely.
  8. Drizzle the cooled cake with the remaining 2 tbsp of maple syrup and garnish with crushed toasted walnuts before slicing and serving.

Notes

Don't Use Quick-Cook Oats: For the dense, textured base, old-fashioned rolled oats are essential.
Apple Choice Matters: Use a firm baking apple like Honeycrisp, Gala, or Braeburn.
Achieving Charred Edges: The combination of thin slicing and a sprinkle of sugar on the apple topping is key.
Let It Cool Fully: This cake needs time to set before slicing.
