Prep and bake the cake
- Preheat the oven to 350°F and grease a 9x13 baking dish so the cake releases cleanly after baking.
- Whisk together the all-purpose flour, granulated sugar, baking powder, and salt, then stir in whole milk, eggs, vanilla extract, and melted butter until just combined.
- Spread the batter into the prepared dish in an even layer so the swirl bakes throughout.
- Beat the softened butter, brown sugar, and cinnamon until fluffy.
- Drop spoonfuls of the cinnamon mixture over the batter and use a knife to swirl it in, creating deep streaks and pockets.
- Bake for 30-35 minutes at 350°F until a toothpick comes out clean and the top is golden.
Glaze and serve
- While the cake is still warm, beat the softened cream cheese, powdered sugar, milk, and vanilla extract until smooth.
- Pour the glaze over the warm cake, letting it pool into every swirl and crevice for a glossy finish.
- Let the glaze soak in for 5 minutes before serving warm.
Notes
Pro tip: Swirl the cinnamon filling gently—leave some streaks visible so you get darker, more defined layers in every slice. Store leftovers covered in the refrigerator up to 4 days; rewarm in the microwave for 15-20 seconds. Freezing works for unfrosted cake only—freeze baked cake (cooled) up to 2 months and glaze after thawing. For a lighter option, use low-fat cream cheese in the glaze for a slightly softer, less tangy finish.
