Cinnamon Bun Cake is what I reach for when I want that warm, sweet cinnamon roll feeling but I do not want to stand around shaping perfect spirals for an hour. You know those days when you are craving something cozy, but you also want it to be doable before your coffee gets cold. This cake hits that sweet spot because it is soft, fluffy, and packed with cinnamon sugar in every bite. It also makes your kitchen smell like a bakery, which honestly fixes a lot of moods. If you have been nervous about yeast, I get it, but I will walk you through it like a friend in your kitchen. 
Cinnamon Bun Cake Recipe
This is the version I make when I want a big slice that tastes like a cinnamon roll but eats like a tender cake. The crumb is light, the swirl is gooey, and the simple icing melts into all the little pockets on top. I like baking it in a 9×13 pan because it feels casual and generous, like something you can bring to a brunch or leave on the counter for snacking.
Before we jump in, quick side note. If you are in a bundt cake mood later, you might love this apple cinnamon ricotta bundt cake. It has that same warm spice vibe, just in a different form.
What you will need
Here is what I actually pull out on my counter. Nothing fancy, just the basics.
- Warm milk (not hot), about 1 cup
- 2 and 1 quarter teaspoons active dry yeast (1 packet)
- 1 third cup sugar (for the dough)
- 1 large egg
- 1 teaspoon salt
- 1 quarter cup melted butter (cooled a bit)
- 3 and 1 quarter cups all purpose flour (give or take a spoonful)
- Filling: 1 cup brown sugar, 2 tablespoons cinnamon, 1 third cup very soft butter
- Icing: 1 and 1 quarter cups powdered sugar, 2 to 3 tablespoons milk, splash of vanilla
Simple directions
1) In a big bowl, stir the warm milk, a pinch of the sugar, and the yeast. Let it sit 5 to 10 minutes until it looks foamy. If it does not foam, your milk might have been too hot or the yeast is old. It happens, no shame, just start again with fresh yeast.
2) Stir in the rest of the sugar, egg, salt, and melted butter. Add flour gradually and mix until it turns into a soft dough. It should be a little tacky but not a sticky mess. If it is super sticky, add a tablespoon of flour at a time.
3) Knead for about 5 minutes by hand or with a mixer if you have one. Put it back in the bowl, cover, and let it rise until puffy, about 60 to 90 minutes depending on how warm your kitchen is.
4) Grease your 9×13 pan. Press the dough into the pan with your hands. It does not have to be perfect, just get it mostly even.
5) Mix brown sugar and cinnamon. Spread the soft butter on top of the dough, then sprinkle the cinnamon sugar all over. Use a butter knife to swirl it around a little so it bakes into ribbons. Try not to over swirl. You want pretty pockets, not total chaos.
6) Cover again and let it rise 25 to 35 minutes while you preheat the oven to 350 F. Bake 22 to 28 minutes until lightly golden and the center looks set. If you tap the pan gently, it should not jiggle like raw dough.
7) Whisk icing and drizzle while warm so it melts into the top. This part is the reward.

Why You’ll Love This Giant Cinnamon Roll Cake
I have made a lot of cinnamon things, but this one gets requested the most. It is basically the comfort of cinnamon rolls without needing to roll and slice perfectly. The edges get a tiny bit crisp, the middle stays soft, and the whole thing feels like a treat that is not trying too hard.
Here is why it works so well:
It is soft for days. If you store it covered, it stays tender and snackable. The icing helps too.
It feeds a crowd. A 9×13 pan is brunch friendly. People can grab a small square or a huge piece, and both feel right.
It is flexible. Add chopped pecans, a little nutmeg, or even a thin layer of apple butter under the cinnamon sugar if you want to play around.
Also, if you are the type who loves a cozy crumble situation, keep this one bookmarked for later: brown butter banana oat cake cinnamon crumble. I am a sucker for anything with cinnamon and a buttery topping.
“I made this Cinnamon Bun Cake for Sunday brunch and it disappeared in ten minutes. My kids asked if we could have it for breakfast all week, and honestly I was not mad about it.”
Perfect for Yeast Beginners
If yeast makes you nervous, this is genuinely a friendly place to start. You are not trying to get perfect rolls or a picture ready swirl. You just need the dough to rise, and the pan shape does the rest. Cinnamon Bun Cake is forgiving like that.
Here is what to watch for if this is your first time:
Look for foam. After you mix yeast with warm milk and a little sugar, foam means you are in business. No foam usually means the yeast did not wake up.
Use your hands. Dough should feel soft and alive. If it feels like paste, add a little flour. If it feels like a rock, add a teaspoon of milk.
Rising is about time and warmth. If your kitchen is cold, put the bowl in the oven with the oven turned off and the light on. It creates a gentle warm spot.
And if you want another easy, comforting bake that still feels special, I am also into this carrot cake ricotta bundt cake. It is soft and not fussy, which is basically my favorite kind of baking.
3 Helpful Tips
This is the part I wish someone had told me the first time I tried a yeasted cinnamon cake. These little details make the difference between good and wow.
1) Warm milk means warm like a bath. If you can comfortably dip a finger in, it is good. If it feels hot, let it cool. Hot milk can mess with yeast.
2) Do not overbake. When it is done, it should be lightly golden and the center should look set, not wet. If you bake it until it is dark brown, it can dry out. Start checking around 22 minutes.
3) Ice it while it is warm. Not piping hot, just warm. The icing melts into that cinnamon layer and makes the top glossy and gooey in the best way.
If you want to make it extra cozy, serve it with hot coffee and a little salted butter on the side. Yes, butter. Try it once and tell me I am wrong.
Baking With Yeast
Yeast is just a tiny living ingredient that likes warmth, a little sugar, and patience. Once you get that, it becomes way less intimidating. For Cinnamon Bun Cake, yeast gives you that fluffy pull apart texture that screams cinnamon roll.
A few quick yeast notes that keep things smooth:
Check the date. Old yeast can be the reason a dough does not rise.
Give it time. Rising times are not exact. If your dough looks doubled and puffy, you are good. If it is still dense, wait a bit longer.
Do not drown it in flour. A slightly tacky dough bakes up softer. Too much flour can make it heavy.
When I am planning ahead, I sometimes make the dough and let it rise in the fridge overnight. The next day, I press it in the pan, add the cinnamon sugar, let it puff up, and bake. It is a nice way to make mornings easier.
Common Questions
Can I make Cinnamon Bun Cake ahead of time?
Yes. Bake it, cool it, and cover it well. I like icing it right before serving, but you can ice it ahead too. It will just soak in more.
What if I only have instant yeast?
You can use it. You can mix it right into the dry ingredients, but I still like to dissolve it in warm milk first because it makes me feel more confident it is alive and working.
How do I store leftovers?
Cover the pan tightly or move slices to an airtight container. Keep it at room temperature for 2 days, or in the fridge for up to 5 days. Warm a slice for 10 to 15 seconds to bring back the soft texture.
Can I freeze it?
Totally. Freeze individual squares wrapped well. Thaw at room temp, then warm briefly. If you can, add fresh icing after thawing for the best look and taste.
Why did my cake turn out dense?
Usually it is one of three things: the yeast did not activate, the dough did not rise long enough, or too much flour got added. Next time, aim for a soft dough and give it a little extra rise time.
A sweet finish and a little nudge to bake
If you have been craving something warm and comforting, Cinnamon Bun Cake is such a satisfying win. You get that fluffy yeasted bite, the gooey cinnamon sugar pockets, and the simple icing that melts right in. Keep it casual, do not stress the swirls, and trust your nose when your kitchen starts smelling like a bakery.
