Step 1

Preheat the oven to 350 F. Spray a loaf pan with cooking spray or grease it with butter.

Step 2

Whisk together the flour, baking soda, baking powder, 1 teaspoon kosher salt, cinnamon and nutmeg in a medium bowl.

Step 3

In a separate medium bowl, whisk together the sugar, eggs, oil, yogurt and vanilla extract.

Step 4

Add the apples to the wet ingredients and fold to combine with a rubber spatula. Add the dry ingredients to the wet ingredients and gently fold everything together until just combined. Scrape the batter into the prepared pan and bake for 40 to 50 minutes until a toothpick inserted into the center of the loaf comes out clean (the loaf will spring back if you press a fingertip down on the top and the loaf pulls away slightly from the sides of the pan). Cool in the pan for 30 minutes to 1 hour before unmolding.

Step 5

In the bowl of a stand mixer fitted with a whisk attachment or in a medium bowl with a hand mixer, whisk together cream cheese and butter at a medium speed until light and fluffy, about 3 to 4 minutes. Whip in vanilla extract, cinnamon, confectioners' sugar, salt  and milk in a medium bowl until combined. If the mixture is too thick, add more milk, 1 teaspoon at a time until desired consistency is reached.

Step 6

Remove the cooled cake from the pan. Slice into 1-inch thick pieces. In a medium skillet over medium heat, working in batches, melt 1 tablespoon butter. Once bubbling, add a slice of apple loaf and toast 1-2 minutes per side until golden. Sprinkle with flaky salt and spread with frosting. Repeat with remaining slices and enjoy!

Step 7

Alternatively, wait for the cake to cool, wrap it tightly in plastic and then foil and freeze until ready to serve. The frosting can be made and stored in the fridge for up to 14 days. To thaw, remove the cake from the freezer and transfer it to the fridge for 8 hours. Remove frosting from the fridge, bring to room temperature, and re-whip to improve the texture. Toast the slices in butter, top with salt, spread with cream cheese frosting and enjoy!
