Step 1

Preheat oven to 350 degrees. Grease cake pan and line the bottom with parchment paper; set aside.

Step 2

In a large bowl, whisk together the almond flour, baking powder, and salt. Add in the coconut oil and use a pastry cutter or your fingers to incorporate the oil into the flour. Whisk in the eggs, one a time. Then add in the maple syrup and vanilla and whisk until combined.

Step 3

Fold in the grated apple to the batter. Pour the batter into the prepared cake pan. Bake for about 30 minutes, or until a toothpick inserted in the middle of the cake comes out clean.

Step 4

Allow the cake to cool completely on a wire baking rack. Sprinkle on powdered sugar if desired.
