In this post, you'll learn everything you need to know—from ingredients to step-by-step instructions and helpful tips for the best results.
Ingredients You'll Need
Main Ingredients
**All-Purpose Flour**
This provides structure to the cake. You'll need about 2 cups for a standard 9x9 or 8x8 inch pan.
**Granulated Sugar**
Adds sweetness to the cake base. The cinnamon swirl will have its own sugar mixture, so the cake itself is only lightly sweetened.
**Butter**
Use melted butter for the cake batter—it makes mixing easier and creates a tender crumb. You'll also need softened butter for the cinnamon swirl.
**Eggs**
Two large eggs bind everything together and add richness. Make sure they're at room temperature for better mixing.
**Milk**
Whole milk or 2% works best for moisture. You can substitute with buttermilk for extra tang, or use plant-based milk if needed.
**Vanilla Extract**
A must for that bakery-quality flavor. Use pure vanilla extract if possible.
**Baking Powder**
This is your leavening agent since we're not using yeast. Make sure it's fresh for the best rise.
**Cinnamon Sugar Swirl**
A mixture of brown sugar, cinnamon, and softened butter creates those beautiful ribbons throughout the cake.
**Powdered Sugar Glaze**
Made with powdered sugar, milk, and vanilla for that signature cinnamon roll finish.
Optional Add-Ins
- Chopped pecans or walnuts for crunch
- A pinch of nutmeg in the cinnamon mixture for extra warmth
- Cream cheese in the glaze for tangy richness
- A tablespoon of maple syrup in the glaze for depth
Step-by-Step Instructions
Step 1: Preheat and Prepare Your Pan
Preheat your oven to 350°F (175°C). Grease a 9x9-inch baking pan with butter or cooking spray, then line it with parchment paper for easy removal later.
**Tip:** Let the parchment paper hang over two sides of the pan—this creates handles that make lifting the finished cake out effortless.
Step 2: Mix the Wet Ingredients
In your large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Add the eggs one at a time, whisking after each addition, then stir in the milk and vanilla extract. The mixture should be smooth and slightly glossy.
Step 3: Add the Dry Ingredients
Add the flour, baking powder, and a pinch of salt directly to the wet ingredients. Stir gently with a wooden spoon or spatula until just combined—you should still see a few small flour streaks. Don't overmix, or your cake will turn out tough instead of tender.
Step 4: Prepare the Cinnamon Swirl
In a small bowl, mix together brown sugar, ground cinnamon, and softened butter until it forms a thick paste. You want it spreadable but not runny—similar to the consistency of natural peanut butter.
Step 5: Layer and Swirl
Pour half of the cake batter into your prepared pan and spread it evenly. Drop spoonfuls of the cinnamon mixture across the surface, then use a butter knife to gently swirl it through the batter—don't mix it completely, just create ribbons. Pour the remaining batter on top and repeat the process with the rest of the cinnamon mixture.
**Tip:** For the prettiest swirls, drag your knife through the batter in a figure-eight pattern rather than circular motions.
Step 6: Bake Until Golden
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. The top should be golden brown and spring back when lightly pressed. Don't overbake, or the cake will be dry.
Step 7: Make the Glaze
While the cake cools slightly, whisk together powdered sugar, milk, and vanilla extract in a small bowl until smooth. The glaze should be thick enough to coat the back of a spoon but thin enough to drizzle. Add more milk if it's too thick, or more powdered sugar if it's too thin.
Step 8: Glaze and Serve
Let the cake cool in the pan for about 10 minutes, then drizzle the glaze generously over the warm cake. The warmth will help the glaze soak in slightly while still creating that beautiful dripped effect. Allow the glaze to set for a few minutes before slicing.
Serving Ideas
You can enjoy Glazed Cinnamon Bun Cake on its own, or serve it with:
- A dollop of whipped cream or vanilla ice cream
- Fresh berries for a pop of color and tartness
- A hot cup of coffee or chai tea
- Extra cinnamon butter spread on warm slices
- A dusting of additional cinnamon sugar
For a more polished look, serve in individual squares on small plates with a fork, or cut into larger pieces for a casual family-style breakfast.
Tips for the Best Results
- **Use room temperature ingredients** for better mixing and a more even texture
- **Don't skip the swirling step**—this is what creates those gorgeous cinnamon ribbons that make this cake special
- **Check for doneness early**—ovens vary, so start checking around the 28-minute mark
- **Glaze while slightly warm**—this creates the perfect balance between a glaze that soaks in and one that sits beautifully on top
- **Let it cool for 10 minutes**—cutting too soon will result in crumbly, messy slices
Storage Instructions
Store leftover Glazed Cinnamon Bun Cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days.
To prevent the cake from drying out, cover it tightly with plastic wrap before placing it in a container. You can warm individual slices in the microwave for 10-15 seconds to bring back that fresh-baked taste.
This cake can be frozen before glazing—wrap it tightly in plastic wrap and aluminum foil, then freeze for up to 2 months. Thaw overnight in the refrigerator and add the glaze before serving.

Compared to store-bought cinnamon rolls loaded with processed ingredients and trans fats, this homemade version gives you control over quality and portion size. It's a lighter option for those looking to enjoy a sweet treat without the guilt of artificial additives—though it's still best enjoyed in moderation as part of a balanced diet.
