Cinnamon Swirl Bundt Cake

The best part of a bundt cake is that it looks like you did something fancy, even when the batter comes together in one bowl and one mixer. This cinnamon swirl version bakes up tall and golden, with a soft, tight crumb that slices cleanly—no crumbling, no dry edges, just a tender cake that smells like warm cinnamon the second you flip it out of the pan.

If you want the full printable version later, you can also find it on my site as this Cinnamon Swirl Bundt Cake recipe, but everything you need to nail it is right here.

Why You’ll Love This Recipe

• The batter is lightly tangy thanks to buttermilk, which keeps the crumb tender and balanced against the 1 cup of sugar.
• Ground cinnamon is mixed into the cake itself, so the flavor doesn’t rely on a frosting or glaze to “show up.”
• The swirl layer gives you those pretty cinnamon ribbons when you slice—especially once the cake is fully cooled.
• Butter and sugar are creamed first, which makes the cake bake up lighter (not dense or gummy).
• A bundt pan naturally creates more crusty edges and a soft center—perfect contrast in every slice.

The Story Behind This Recipe

I made this cake when I wanted something cinnamon-forward that still felt simple: no yeast, no glaze, no extra components—just a straightforward bundt that leans on proper creaming, buttermilk, and a cinnamon-sugar middle for that bakery-style swirl look.

What It Tastes Like

It’s gently sweet with a clear cinnamon aroma and a buttery, vanilla background. The crumb is plush and moist (but not wet), and the swirl area bakes into a slightly darker, more fragrant stripe that tastes like the center of a coffee cake—warm, toasty, and just a little tangy from the buttermilk.

Ingredients You’ll Need

Buttermilk is the quiet hero here—it reacts with the baking soda for lift and adds a subtle tang that keeps the cake from tasting flat. Softened butter (not melted) is key because you’re creaming it with sugar to build air, which helps the bundt bake up light. If you don’t have buttermilk on hand, you can still make this, but the flavor and tenderness will be a bit less pronounced.

• 2 cups all-purpose flour
• 1 ½ teaspoons baking powder
• 1 teaspoon baking soda
• 1 cup sugar
• 1 teaspoon ground cinnamon
• ½ teaspoon salt
• ½ cup unsalted butter, softened
• 3 large eggs
• 1 teaspoon vanilla extract
• 1 cup buttermilk

How to Make Cinnamon Swirl Bundt Cake

1. Heat the oven and prep the pan. Preheat to 350°F (175°C). Grease a bundt pan very thoroughly, making sure to get into all the ridges—this cake has a tender crumb and you want a clean release.
2. Whisk the dry ingredients. In a large bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt until the cinnamon looks evenly distributed (no streaky pockets).
3. Cream the butter and sugar. In a separate bowl, beat the softened butter and sugar until creamy and noticeably lighter in color. You’re looking for a fluffy texture that clings to the beaters rather than looking glossy or oily.
4. Add eggs and vanilla. Beat in the eggs one at a time, mixing until each one disappears into the batter before adding the next. Stir in the vanilla extract; the mixture should look smooth and cohesive.
5. Alternate dry ingredients and buttermilk. Add the dry ingredients and buttermilk in alternating additions, mixing gently just until you no longer see dry flour. Stop as soon as the batter looks thick and smooth—overmixing can make the cake bake up tougher.
6. Layer the batter. Spoon half the batter into the greased bundt pan and spread it evenly so the layer is level.
7. Make the swirl layer. Sprinkle an even layer of cinnamon and sugar over the batter. Aim for consistent coverage so every slice gets some swirl.
8. Top and bake. Add the remaining batter and smooth the top. Bake for 50–60 minutes, until a toothpick inserted comes out clean. The cake should look set and deeply golden, and the top should spring back lightly when touched.
9. Cool before unmolding. Let the cake cool in the pan before inverting onto a plate. This cooling time helps the crumb firm up so the bundt releases in one piece.

Tips for Best Results

• Grease every curve of the bundt pan. Missed spots are the #1 reason a pretty swirl bundt loses chunks on the way out.
• Butter must be softened, not melted. Softened butter creams with sugar into a pale, airy base; melted butter can make the batter heavy and the cake denser.
• Mix just until combined once flour is added. When you stop mixing at “no visible flour,” you get a softer crumb and a cleaner slice.
• Spread the first batter layer evenly. A level base helps the cinnamon-sugar layer sit in a defined ribbon instead of sliding to one side.
• Cool patiently before flipping. If you invert too early, the cake can tear; if you wait until it’s set, it unmolds more cleanly and slices neater.

If you’re on a cinnamon kick, you might also like my mini cinnamon roll cheesecakes for a more decadent, creamy take with the same cozy spice vibe.

Variations and Substitutions

• Make the cinnamon note stronger: Increase the ground cinnamon slightly if you like a bolder spice presence (it will deepen the aroma and darken the crumb a touch).
• Turn it into a breakfast-style spread: Serve it alongside something fresh and simple; I like pairing it with 3-ingredient banana oatmeal pancakes when I’m doing a relaxed brunch table.
• Try a different “swirl dessert” next: If you love the look of swirls, my easy blueberry cheesecake swirl cookies are a fun, smaller-batch option.

How to Serve It

Slice it once it’s fully cooled for the cleanest swirl. I love serving it slightly warm (a quick few minutes at room temp does the trick) so the cinnamon aroma blooms again. It’s great with coffee or black tea, and if you’re putting together a fall dessert spread, these apple crumble cupcakes make a nice fruity contrast on the same platter.

How to Store It

Keep the cake covered at room temperature for a couple of days so the crumb stays soft. For longer storage, refrigerate it well covered and bring slices back to room temperature before serving so the butter in the cake doesn’t taste firm. You can also freeze slices tightly wrapped; thaw overnight in the fridge, then let them sit out briefly before eating.

Final Thoughts

This is the kind of bundt cake that earns its keep: simple ingredients, a reliable rise, and that cinnamon-sugar ribbon that makes every slice look intentional. Take your time greasing the pan and don’t overmix once the flour goes in—you’ll get a tall, tender cake with a warm spice perfume that’s hard to resist.
