Method
Prepare the oven and apple layer
- Preheat the oven to 350F and grease a 9x13 baking dish so the cake releases cleanly after baking.
- Toss the diced apples with brown sugar, cinnamon, and nutmeg, then set aside while you mix the batter.
Make the cake batter
- Beat the softened unsalted butter and granulated sugar until fluffy to build a lighter crumb.
- Add the eggs one at a time, then mix in the vanilla extract until smooth and glossy.
- Whisk the all-purpose flour, baking powder, and salt, then alternate adding the dry mix and whole milk to the butter mixture in batches until just combined.
Assemble and bake
- Spread half the batter into the greased 9x13 baking dish, then scatter half of the cinnamon apple mixture over the surface.
- Spread the remaining batter on top, add the remaining apples, then swirl the top with a knife for a marbled cinnamon effect.
- Bake at 350F for 40-45 minutes, until golden and a toothpick comes out clean in the center.
Glaze and serve
- Cool the cake for 15 minutes so the glaze sets without melting into the crumb.
- Drizzle the powdered sugar glaze over the warm cake in irregular stripes, then let it set before slicing.
Notes
Pro tip: dice the apples small and even so they soften and distribute throughout the cake without leaving large pockets. Store covered in the fridge for up to 4 days; freeze slices for up to 2 months. For a lighter option, use low-fat milk in the batter and glaze (texture will stay close, sweetness unchanged).
