Line an 8-inch round pan with parchment paper and lightly grease the sides.

In a large bowl, whisk flour, almond flour, baking powder, baking soda, salt, cinnamon, and nutmeg.

In another bowl, whisk together olive oil, coconut sugar, eggs, Greek yogurt, apple cider, vanilla, and orange zest (if using) until smooth.

Stir in the grated apple.

Add the dry ingredients to the wet and mix gently until just combined — the batter will be slightly thin, and that’s perfect.

Pour into the prepared pan and bake for 35–40 minutes, or until a toothpick comes out clean and the top is golden.

Let the cake cool, then drizzle with maple glaze or dust with powdered sugar.
