Method
Prep and apple filling
- Preheat oven to 350F and grease a 9x13 baking dish so the cake releases easily.
- Toss diced apples with brown sugar, cinnamon, and nutmeg, then set aside while you mix the batter.
Make the cake batter
- Beat softened unsalted butter and granulated sugar until fluffy, then add eggs and vanilla extract and mix until smooth.
- Whisk all-purpose flour, baking powder, and salt, then alternate adding the dry mix and whole milk to the butter mixture until just combined.
Assemble and bake
- Spread half the batter in the prepared pan, then scatter half the cinnamon apple mixture over the top.
- Add remaining batter and top with remaining apples, then swirl with a knife to create a cinnamon-swirled look.
- Bake for 40-45 minutes at 350F until the cake is golden and a toothpick comes out clean.
Cool and glaze
- Cool the cake for 15 minutes so the glaze sits on top instead of soaking in.
- Whisk powdered sugar with 2-3 tablespoons milk and vanilla extract until thick, then drizzle over the cake in irregular stripes.
Notes
Pro tip: Swirl the top lightly with a knife after layering so you get visible cinnamon pockets like a classic apple fritter. Store covered in the refrigerator for up to 4 days; freeze (unglazed if possible) for up to 2 months and thaw overnight in the fridge, then warm briefly and glaze. For a lighter option, replace half the butter with plain Greek yogurt and expect a slightly softer crumb.
