Preheat oven to 350.
Line a standard loaf tin (11x5) with parchment paper, with enough for an overhang.
Peel and core the apples. If you don’t have an apple corer, slice the peeled apple in half and use a teaspoon to take out the core.
Set your mandolin to a thin setting. You want the slices to be thin enough to bend. USE THE SAFETY DEVICE TO AVOID INJURY.
In a large bowl, whisk eggs, honey, butter and vanilla until smooth.
Add dry ingredients and whisk until the mixture is fully combined. The batter will be a little runny, and that is good.
Fold the apples into the batter until well coated.
Transfer into the prepared loaf pan, smoothing the top as best as you can with a spatula.
Top with sliced almonds.
Bake for 52-55 minutes or until the top is golden brown.
Allow the cake to rest in the tin for 15 minutes.
Remove from the tin and allow it to rest on a wire rack for 1 hour.
Dust with icing sugar if desired.
Slice and serve with Greek yogurt or ice cream.
