Step 1

Preheat the oven to 325°F. Grease and line an 8-inch springform pan with parchment paper.

Step 2

In a large bowl, combine the egg yolks, almond flour, wine, baking powder, cinnamon and kosher salt.

Step 3

Add the walnuts and chopped apples to the almond flour mixture, folding with a rubber spatula to combine. Set aside.

Step 4

In a large bowl, combine the egg whites and sugar. Using a hand mixer or stand mixer, whisk the egg whites until soft peaks form, about 5-7 minutes.

Step 5

Gently fold the egg whites into the almond flour mixture, ½ cup at a time, folding between each addition until fully incorporated.

Step 6

Transfer to the springform pan and bake for 45-50 minutes, or until a toothpick comes out clean.

Step 7

Remove from the oven, and use a pastry brush to brush the honey on top.

Step 8

Let cool in the pan, and slice to serve.
