Imagine a cake that takes all the cozy, gooey goodness of a cinnamon roll and transforms it into a gorgeous, shareable treat—enter the Cinna Bun Cake. The swirls of cinnamon-sugar goodness wrapped in a tender, buttery cake are pure bliss. And then there’s that glossy caramelized glaze that melts right into every bite, leaving you craving more.

I love how this cake fills the kitchen with the warm, comforting aroma of cinnamon as it bakes. It’s a perfect choice for breakfast, brunch, or a decadent dessert. And the best part? It’s surprisingly simple to make but looks like something straight out of a fancy bakery. Whether you’re serving it for a special occasion or just because you’re craving something sweet and cozy, this cake delivers every single time.

Why You’ll Love This Cinna Bun Cake

Irresistibly Gooey: The caramelized glaze and cinnamon-sugar filling make each bite luxuriously sticky and sweet.
Easy to Make: No complicated steps—just simple, straightforward baking.
Perfect for Sharing: Its pull-apart style makes it great for gatherings and special mornings.
Customizable: You can tweak the filling or add nuts and other extras to make it your own.
Heavenly Aroma: Your kitchen will smell like a cinnamon roll paradise.

What Kind of Flour Should I Use for Cinna Bun Cake?

For the best texture, I recommend using all-purpose flour. It provides the perfect balance of structure and tenderness for this cake. However, if you want a softer, fluffier cake, you can substitute part of the all-purpose flour with cake flour—about a quarter of the total amount. Just keep in mind that cake flour will result in a more delicate crumb.

Options for Substitutions

While the classic Cinna Bun Cake recipe is already delicious, there’s room for creativity and dietary preferences. Here are some ideas:

Flour Alternatives: Swap all-purpose flour with a gluten-free baking blend for a gluten-free version.
Sugar Options: Use coconut sugar or brown sugar instead of white sugar for a deeper, richer flavor.
Dairy-Free Option: Replace butter with vegan butter or coconut oil, and use plant-based milk instead of regular milk.
Add-ins: Chopped pecans or walnuts can add a delightful crunch to the cinnamon swirls.
Frosting Variation: Instead of the caramel glaze, try a classic cream cheese frosting for a tangy-sweet finish.

Don’t be afraid to mix things up! This cake is pretty forgiving, so feel free to experiment to suit your taste.

Ingredients for this Cinna Bun Cake

Each ingredient plays a special role in making this cake so irresistible. Here’s a breakdown of why you need each one:

All-Purpose Flour: Provides the perfect structure and softness for the cake. You can mix with cake flour for a more delicate crumb.
Granulated Sugar: Sweetens the cake and helps create a tender texture.
Brown Sugar: Adds depth and richness to the cinnamon swirl filling, enhancing that classic cinnamon roll flavor.
Butter: Adds moisture, richness, and a buttery flavor that complements the cinnamon sugar beautifully.
Milk: Ensures a moist, tender crumb and helps bring the batter together.
Eggs: Bind the ingredients and contribute to the cake’s fluffy texture.
Baking Powder: Gives the cake its lightness and rise, making it airy and soft.
Salt: Enhances all the flavors and balances the sweetness.
Ground Cinnamon: The star of the show—providing that warm, spicy flavor that defines this cake.
Vanilla Extract: Adds a subtle, cozy sweetness to the batter.
Heavy Cream (for glaze): Creates a rich, luscious caramel-like glaze that coats the cinnamon swirls perfectly.

All of these ingredients come together to form a cake that’s soft, flavorful, and melt-in-your-mouth good. Make sure to use fresh cinnamon for the most vibrant flavor!

Step 1: Prepare the Pan and Preheat the Oven

Grease a 9-inch round cake pan generously with butter or non-stick spray. Preheat your oven to 350°F (175°C). This ensures your cake bakes evenly from the start.

Step 2: Make the Cake Batter

In a large mixing bowl, cream together 1/2 cup softened butter and 1 cup granulated sugar until light and fluffy. Add 2 large eggs, one at a time, mixing well after each addition. Stir in 1 teaspoon vanilla extract.

In a separate bowl, whisk together 2 cups all-purpose flour, 1 tablespoon baking powder, and 1/2 teaspoon salt. Gradually add the dry ingredients to the wet mixture, alternating with 1 cup milk, until just combined. Be careful not to overmix.

Step 3: Prepare the Cinnamon Swirl Filling

In a small bowl, mix together 1/2 cup softened butter, 1 cup brown sugar, and 2 tablespoons ground cinnamon until smooth and spreadable. This mixture should have a thick, paste-like consistency.

Step 4: Assemble the Cake

Pour half of the cake batter into the prepared pan and spread it evenly. Spoon dollops of the cinnamon filling over the batter, then swirl it gently with a knife or toothpick. Pour the remaining batter over the swirls and smooth the top.

Step 5: Bake the Cake

Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden and the edges slightly pulling away from the pan.

Step 6: Prepare the Caramel Glaze

While the cake bakes, make the glaze by heating 1/2 cup heavy cream and 1/2 cup brown sugar in a small saucepan over medium heat. Stir constantly until the sugar dissolves and the mixture thickens slightly—about 5-7 minutes. Remove from heat and let cool slightly.

Step 7: Add the Glaze and Serve

Once the cake is baked, remove it from the oven and allow it to cool in the pan for 10 minutes. Pour the warm caramel glaze over the cake, letting it seep into the swirls. Serve warm or at room temperature.

This step-by-step process ensures your Cinna Bun Cake turns out gooey, sweet, and utterly irresistible every single time.

How Long to Cook the Cinna Bun Cake

The baking time for this Cinna Bun Cake is typically 30–35 minutes at 350°F (175°C). You’ll know it’s ready when the top is golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs.

If you prefer a slightly gooey texture, you can pull it out a minute or two earlier. For a fully set, fluffy cake, let it bake closer to the 35-minute mark. Keep an eye on it during the last few minutes to avoid overbaking.

Tips for Perfect Cinna Bun Cake

Achieving that perfect, gooey, cinnamon-infused texture isn’t hard if you keep these tips in mind:

Don’t Overmix: When combining the dry and wet ingredients, mix just until combined to avoid a dense cake.
Room Temperature Ingredients: Using room temperature butter and eggs ensures a smoother, more even batter.
Swirl Like a Pro: When adding the cinnamon filling, use a butter knife or toothpick to create beautiful, deep swirls without overmixing.
Use Fresh Cinnamon: Freshly ground cinnamon will have a more robust flavor than the stuff that’s been sitting in your pantry for months.
Mind the Glaze Temperature: Pour the glaze over the cake while it’s still warm for better absorption and that perfect sticky finish.
Check for Doneness Properly: If the toothpick comes out clean from the center but feels sticky from the glaze—don’t worry, that’s perfect.
Cooling Matters: Letting the cake cool for about 10 minutes before glazing helps it hold its shape while allowing the glaze to seep in.

With these tips, your Cinna Bun Cake will turn out incredibly delicious every time!

Watch Out for These Mistakes While Cooking

Even a simple recipe like Cinna Bun Cake can trip you up if you’re not careful. Here are some common mistakes to avoid:

Overmixing the Batter: This can result in a dense, tough cake. Mix until just combined for a soft, tender crumb.
Skipping the Swirl Step: Make sure to swirl the cinnamon filling into the batter for that classic layered look and taste.
Pouring the Glaze Too Early: If the cake is too hot, the glaze may slide right off instead of soaking in. Let it cool for about 10 minutes before glazing.
Using Cold Ingredients: Cold butter or eggs can cause the batter to curdle, leading to an uneven texture.
Overbaking: The cake can dry out quickly if left in the oven too long. Check it around the 30-minute mark.
Forgetting to Grease the Pan: Non-stick spray or butter is essential to prevent the cake from sticking and breaking apart.
Ignoring Ingredient Quality: Fresh cinnamon and high-quality vanilla extract make a noticeable difference in flavor.
Neglecting the Cooling Process: Allow the cake to cool slightly before serving to let the flavors meld perfectly.

What to Serve With Cinna Bun Cake?

This rich, cinnamon-swirled cake pairs beautifully with a variety of sides and beverages. Here are eight delicious recommendations:

1. Fresh Coffee

The deep, bold flavor of a hot coffee perfectly complements the sweetness of the cake. A cappuccino or latte works especially well.

2. Vanilla Ice Cream

For a decadent dessert experience, serve a warm slice with a scoop of vanilla ice cream melting over the top.

3. Whipped Cream

Light and airy, whipped cream adds a touch of creaminess without overpowering the cake’s cinnamon flavor.

4. Fresh Berries

Raspberries or strawberries offer a tart, juicy contrast to the cake’s rich sweetness.

5. Hot Cocoa

During colder months, a mug of creamy hot cocoa makes the perfect cozy pairing.

6. Spiced Chai Latte

The warm spices in chai enhance the cinnamon notes of the cake beautifully.

7. Greek Yogurt

A dollop of tangy Greek yogurt balances out the cake’s sweetness for a more sophisticated flavor profile.

8. Warm Apple Compote

Serving the cake with a spoonful of apple compote adds extra fruity warmth and sweetness.

These pairings make the Cinna Bun Cake even more enjoyable, whether you’re serving it for breakfast, brunch, or dessert.

Storage Instructions

Storing your Cinna Bun Cake properly ensures it stays fresh and delicious for days. Here’s how to do it:

Room Temperature: If you plan to enjoy the cake within 2 days, keep it covered with plastic wrap or stored in an airtight container at room temperature.
Refrigeration: For longer storage, place the cake in an airtight container and refrigerate. It will stay fresh for up to 5 days. Allow slices to come to room temperature or gently reheat before serving.
Freezing: To freeze, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. It will keep well for up to 3 months. Thaw at room temperature or microwave for a quick treat.

The caramel glaze may firm up when chilled, but a few seconds in the microwave will restore its gooey goodness.
