Method
Bake the cake
- Preheat the oven to 350°F and grease a 9x13 baking dish so the batter won’t stick.
- Whisk together all-purpose flour, granulated sugar, baking powder, and salt.
- Stir in whole milk, large eggs, vanilla extract, and melted butter until just combined.
- Spread the batter into the prepared dish in an even layer.
- Beat softened butter, brown sugar, and cinnamon until fluffy, then drop spoonfuls over the batter.
- Use a knife to swirl the cinnamon mixture into the batter, creating marbled streaks throughout (keep swirls visible on top).
- Bake for 30–35 minutes until a toothpick comes out clean and the top is golden.
Glaze and serve
- While the cake is still warm, beat cream cheese, powdered sugar, milk, and vanilla extract until smooth.
- Pour the glaze over the warm cake so it pools into every swirl and crevice.
- Let the glaze soak in for 5 minutes before serving warm.
Notes
Pro tip: swirl the cinnamon mixture lightly with a knife so you get distinct, dark-brown ribbons instead of fully mixed batter. Store covered in the refrigerator up to 4 days; rewarm individual slices in the microwave for 15–25 seconds. Freezing is yes—freeze slices (without topping on top if you prefer) up to 2 months and thaw overnight in the fridge. For a lighter option, use 1% milk in the cake and glaze for a small reduction in richness while keeping the swirl and glaze texture.
