Preheat the oven to 350 degrees Fahrenheit, then line a 9 x 5-inch loaf pan with parchment paper and spray lightly with nonstick cooking spray. Set aside.
Whisk together 3 large eggs, ⅔ cup granulated sugar, ⅓ cup melted unsalted butter, ⅔ cup slightly warm milk, and 2 teaspoons vanilla paste in a large bowl until combined and frothy.
In a separate bowl, whisk together ⅔ cup all-purpose flour, 1 ½ teaspoons baking powder, ½ teaspoon salt, ½ teaspoon ground cinnamon, and 1-2 pinches ground nutmeg.
Add the flour mixture to the egg mixture and whisk until combined. The batter should be quite thin and runny.
Let the batter rest while you peel, core, and very thinly slice 6 medium apples with a mandolin or sharp knife. The slices should be about 1/8 to 1/16-inch thick. This is quite thin, so be very careful!
Add the apples to the batter and toss until combined.
One handful at a time, layer the apples into the prepared loaf pan. Make them as even as you can, but don't fuss too much, as they will fill in any gaps as they bake. If desired, arrange the final apples in a design on top.
Pour any remaining batter over the apples.
Bake for 60-65 minutes, until a toothpick comes out clean from the center of the cake, and the apples on top begin to brown. If the apples are browned but the cake is not done, tent with foil to prevent burning.
Let the cake cool in the pan for 20 minutes, then transfer to a cooling rack to cool completely. Slice once fully cooled, or after chilling in the refrigerator for an hour or two.
Notes
Storage Recommendations
Fridge: Store leftover invisible apple cake in an airtight container or covered tightly with plastic wrap in the refrigerator for up to 5 days.
Freezer: Not recommended, as it can disrupt the cake's integrity.
Make Ahead: This cake needs time to fully cool, then chill in the refrigerator for at least a few hours before slicing, so plan ahead.
