Know Before You Scroll

What You’ll Need

All-purpose flour, baking powder, baking soda, salt, butter, granulated sugar, eggs, buttermilk, vanilla extract, light brown sugar, cinnamon, powdered sugar, cream cheese, milk, optional pinch of salt.

Flavor Profile

Soft, buttery vanilla cake with a gooey cinnamon swirl and a sweet cream cheese glaze that drips into every bite—like a cinnamon roll meets coffee cake.

Difficulty Level

Easy. If you can swirl batter with a spoon, you can totally handle this one.

Equipment Needed

Mixing bowls, whisk, hand or stand mixer, spatula, knife or skewer for swirling, 9×13-inch baking pan, parchment paper.

Top Tip

Don’t overmix the cake batter—this keeps the crumb soft and tender.

Make Ahead

Bake the cake a day ahead, store covered at room temp, and drizzle glaze just before serving for the freshest look.

Ingredient Swaps

No buttermilk? Mix regular milk with a splash of vinegar or lemon juice and let it sit for 5 minutes.

All the Swirls, None of the Waiting

My son’s favorite dessert is hands-down cinnamon rolls, but let’s be honest—there isn’t always time to make them from scratch. I tried a few different versions of cake for this cinnamon bun cake—some came out too dry, some too flat, and some just didn’t have that gooey swirl moment I wanted. Then I thought, why not start with my tried-and-true NJ crumb cake base? It never fails me, and once I layered in the brown sugar and cinnamon ribbons, it finally clicked. Soft, fluffy, perfectly sweet—basically the shortcut cinnamon roll cake of my dreams.

Ingredient Notes

Various baking ingredients for a delicious Cinnamon Bun Cake, including flour, sugar, brown sugar, butter, eggs, milk, vanilla extract, salt, cocoa powder, and sour cream, are displayed in glass containers and bowls on a white countertop. - 14

Dry Ingredients

Best Choice

All-purpose flour, baking powder, baking soda, and fine table salt.

Substitutions

Cake flour can be used for an even lighter texture, but avoid bread flour—it’s too heavy. Baking powder and baking soda are not interchangeable, so stick with the exact amounts listed.

Wet Ingredients

Best Choice

Unsalted butter (Not European style butter – see notes below), granulated sugar, large eggs, buttermilk, and pure vanilla extract.

Substitutions

Salted butter works if you reduce the added salt. For buttermilk, make your own with milk + vinegar or lemon juice. Vanilla bean paste or imitation vanilla can be swapped in a pinch. Flax eggs can stand in for real eggs, though the cake will be less fluffy.

Cinnamon Swirl

Best Choice

Softened butter, light brown sugar (packed), a touch of flour, and ground cinnamon.

Substitutions

Dark brown sugar gives a deeper molasses flavor. Pumpkin pie spice can replace cinnamon for a warm twist.

Cream Cheese Glaze

Best Choice

Full-fat cream cheese, powdered sugar, milk, vanilla extract, and a tiny pinch of salt to balance sweetness.

Substitutions

Neufchâtel cheese works for a lighter option. Any type of milk (dairy or non-dairy) is fine.

A Quick Note for Non-U.S. Kitchens

We thoroughly test our recipes, and during testing in both the UK and Europe we noticed that the cinnamon swirl often sinks to the bottom of the cake. Honestly? It still tastes amazing — like a gooey cinnamon-sugar layer baked right into the base. If you’d prefer a swirl that stays more evenly marbled, try making the mixture with just cinnamon and sugar instead of butter. Both versions are completely delicious — it just depends if you’re after gooey pockets of cinnamon or a more even swirl throughout.

Step By Step Instructions

Preheat & Prep

start by preheating the oven to 350°F/175°C and grease a 9×13-inch baking pan.

Mix the Dry Ingredients

In a medium bowl, whisk together 3 and a half cups of flour, three-quarters teaspoon baking powder, one and a half teaspoons baking soda, and three-quarters teaspoon salt. Just a quick whisk to combine.

Cream the Butter and Sugar

In a large bowl, beat one cup plus two tablespoons softened butter with 2 cups sugar until light and fluffy. This is what makes the cake so soft and rich.

Make the Cream Cheese Glaze

Ingredients

For the Cake

▢ 3½ cups all-purpose flour
▢ ¾ teaspoon baking powder
▢ 1½ teaspoons baking soda
▢ ¾ teaspoon salt
▢ 18 tablespoons unsalted butter ((2 sticks + tablespoons), softened)
▢ 2 cups granulated sugar
▢ 3 large eggs
▢ 1¾ cups buttermilk
▢ 2 teaspoons vanilla extract

For the Cinnamon Swirl

▢ 16 tablespoons butter ((2 sticks), softened)
▢ 1 cup light brown sugar (packed)
▢ 2 tablespoons all-purpose flour
▢ 1 tablespoon ground cinnamon

For the Cream Cheese Glaze

▢ 4 oz cream cheese (softened)
▢ 1¾ cups powdered sugar
▢ ¼ cup milk (adjust as needed for drizzling consistency)
▢ 1 teaspoon vanilla extract
▢ 1 pinch of salt (optional to balance sweetness)

Instructions

Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.

Make the Cake Batter:

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large mixing bowl, cream the softened butter and sugar together until light and fluffy.
Beat in the eggs one at a time, then add vanilla.
Alternate adding the dry ingredients and buttermilk, starting and ending with the dry mix. Mix just until combined—don’t overmix!
Pour batter into the pan, spreading it evenly with a spatula.

Make the Cinnamon Swirl:

In a small bowl, stir together the butter, brown sugar, flour, and cinnamon until smooth and spreadable.
Drop spoonfuls of the cinnamon mixture over the batter, then swirl with a knife or skewer to marble it into the top half of the batter.
Bake for 40–50 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs (not wet batter).

Make the Cream Cheese Glaze:

Beat the cream cheese until smooth. Add powdered sugar, milk, vanilla, and a pinch of salt if using, whisking until pourable and silky. Adjust with more milk or sugar to reach your ideal drizzling consistency.
Drizzle glaze over warm cake—right out of the oven for a melty effect, or wait until slightly cooled for defined ribbons.

Tips

Erren’s Top Tips

Room Temperature is Key: Make sure your butter, eggs, and cream cheese are at room temperature. They’ll mix more smoothly, and your cake will bake up light and fluffy.
Don’t Overmix the Batter: Once the dry and wet ingredients are combined, stop mixing. Overmixing develops gluten, which makes the cake dense instead of tender.
Swirl Gently, Not Deeply: When adding the cinnamon swirl, only marble the top half of the batter. This keeps it from sinking straight to the bottom.
Use the Toothpick Test Wisely: Look for a few moist crumbs clinging to the toothpick, not a completely dry pick. That’s how you know your cake is perfectly baked.
For a Clean Slice: Let the glaze set for 10–15 minutes before cutting, or chill briefly. It’ll slice neatly without dragging the glaze.

Storage & Freezing

Room Temperature: Store covered at room temperature for up to 2 days. The glaze will soak in a bit, making the cake extra moist.
Refrigerator: For longer storage, cover tightly and refrigerate for up to 5 days. Bring to room temperature before serving for the best flavor.
Freezing: Slice the cake into squares, wrap individually in plastic wrap, and freeze in a freezer bag for up to 2 months. Thaw overnight in the fridge, then warm slightly in the microwave or oven before serving.
Glaze Note: If freezing, consider glazing after thawing for the prettiest presentation.

Why did my cinnamon swirl sink to the bottom?

Butter and flour can behave differently depending brand or where you live. In countries outside the US, butter usually has a higher fat content and less water than American butter, which makes the cinnamon swirl mixture heavier. That extra richness can cause the swirl to sink toward the bottom. If you’d like a swirl that stays more evenly marbled, try using just cinnamon and sugar instead of butter. Both versions taste amazing — one gives you gooey pockets of cinnamon, the other a more even swirl.

Can I make this ahead of time?

Yes! You can bake the cake a day in advance and drizzle the glaze just before serving. This keeps the glaze fresh and pretty.
