Ingredients

Scale

Apples

  • 6 large Apples (about 1.4 kg, peeled and grated)
  • 23 tablespoons Lemon juice (freshly squeezed)

Dry Ingredients

  • 4 cups Rolled oats/quick oats/oat flour (360g if using oats to blend)
  • ¾ cup Granulated sugar (plus 1 tablespoon for topping)
  • 1 teaspoon ground cinnamon

Wet Ingredients & Topping

  • 2/3 cup Unsalted butter (cold, divided: about 30g for base grated, 125g for topping)

Instructions

  1. Preheat & Prepare the Pan: Preheat your oven to 180°C (350°F). Line a 9-inch (23cm) springform pan with parchment paper and set aside to ensure easy removal of the cake after baking.
  2. Make Oat Flour (if needed): If not using store-bought oat flour, measure 4 cups (360g) of rolled oats and blend them in a food processor or blender until a coarse flour forms. A little texture is good for the cake.
  3. Make the Oat Mixture: In a large mixing bowl, combine the oat flour, granulated sugar, and ground cinnamon. Stir well to evenly distribute all dry ingredients for balanced flavor.
  4. Grate the Apples: Peel and grate the apples using a box grater. Place the grated apples into a bowl, sprinkle with freshly squeezed lemon juice to prevent browning, and let them sit to release some juice.
  5. Layer the Cake: Grate about 2 tablespoons (30g) of cold butter into the bottom of the prepared pan. Sprinkle 3–4 tablespoons of the oat mixture over the butter, pressing gently to form the base layer. Spread one-third of the grated apples, including their juice, evenly over the oats. Repeat layering twice more: oat mixture, then apples, finishing with the oat mixture on top. Grate the remaining 125g of cold butter over the top layer. Sprinkle the remaining tablespoon of sugar to create a golden, caramelized crust.
  6. Bake: Place the pan in the preheated oven and bake for 35–45 minutes, until the top is a beautiful golden brown and the apples are soft and bubbling.
  7. Cool & Serve: Allow the cake to cool in the pan for about 20 minutes before releasing the springform. Let it cool completely for best texture. Serve warm or at room temperature for a delicious treat.

Notes

  • You can use a combination of rolled oats, quick oats, and oat flour for texture variety in the cake.
  • Grating cold butter directly into layers helps create a tender, flaky crust.
  • Lemon juice on apples prevents browning and adds a subtle tang.
  • This cake can be stored covered in the refrigerator for up to 3 days and is delicious reheated slightly.
