Roasting the apples before adding them to the cake amplifies their natural sweetness. The fragrant cardamom and nutty almonds round out the wintry flavor of this warming cake.
For the topping:1.
Preheat the oven to 400°F. Line a rimmed baking sheet with parchment paper.2.
Put the apples on the prepared baking sheet, drizzle with the coconut oil and maple syrup and toss well to evenly coat. Spread out evenly and roast for 20 minutes. Remove the pan form the oven and gently turn the fruit over. Return to the oven and roast for another 10 minutes, or until the apples are golden brown and tender.3.
Remove from the oven, slide the apples off the parchment onto a plate (they will stick if left to cool on the parchment) and set aside while you prepare the cake.
For the almond cake:1.
Preheat the oven to 350°F. Line a 9-inch round cake pan with parchment paper, creasing the paper against the sides of the pan as necessary.2.
Put the almond flour in a medium bowl and use your fingertips to work out any lumps. Sift in the oat flour, baking powder and cardamom and whisk to combine; set aside.3.
Beat the eggs in another medium bowl. Add the maple syrup, coconut oil, vanilla, almond extract and salt and whisk to combine. Pour into the almond flour mixture and stir with a rubber spatula until just combined.4.
Pour the batter into the prepared pan and spread it out evenly with a rubber spatula. Arrange the apples over the top and sprinkle with chopped almonds.5.
Bake for 35-40 minutes, until the cake is golden on top and a toothpick inserted into the center comes out clean.6.
Remove from the oven and set on a rack to cool for at least 10 minutes before removing from the pan. Serve slightly warm or at room temperature. Cover any leftover cake and store for 1 day at cool room temperature or up to 4 days in the fridge; allow to come to room temperature before serving.
