Cinnamon Swirl Bundt Cake

Warm cinnamon and vanilla hit you first, then that buttery, tender crumb gives way to a sweet swirl tucked into every slice. This Cinnamon Swirl Bundt Cake bakes up tall and golden, with a cozy aroma that makes your kitchen smell like a bakery long before the timer goes off.

It’s also wonderfully straightforward—simple pantry ingredients, one batter, and a layered cinnamon-sugar moment in the middle. If you’re new around here, you can get to know my approach (and why I’m so picky about “just combined” batter) on the about Citrus and Crave page.

Why You’ll Love This Recipe

• The swirl is built right in: you pour half the batter, sprinkle cinnamon-sugar, then top with the rest for a defined ribbon through the cake.
• Buttermilk keeps the crumb soft and tender, so the cake stays plush instead of dry or tight.
• Cinnamon shows up in both the batter and the swirl, so the flavor is warm and clear—not faint.
• A bundt pan makes it look special with almost no decorating effort (those ridges do the work).
• The method is forgiving as long as you stop mixing once the flour disappears—no fancy techniques needed.

The Story Behind This Recipe

I wanted a cinnamon-forward bundt that felt like coffee cake but sliced cleanly like a classic butter cake, and this one hits that sweet spot: a simple vanilla batter enriched with butter and eggs, plus a cinnamon-sugar layer that perfumes the whole cake as it bakes. For the fine print around general recipe guidance, I keep notes on my recipe disclaimer page.

What It Tastes Like

Expect a gently sweet, buttery cake with a clear cinnamon fragrance and a soft, even crumb—thanks to the buttermilk and the balance of baking powder and baking soda. The swirl gives little pockets of deeper cinnamon sweetness, and the edges bake up lightly golden where the batter meets the pan.

Ingredients You’ll Need

This recipe is all about a simple, well-balanced batter: butter and sugar creamed until fluffy for lift, eggs for richness and structure, and buttermilk for tang and tenderness. Cinnamon is used in the dry mix (so the cake tastes like cinnamon, not just the swirl), and the leaveners work together to keep the bundt from baking up heavy.

• 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 thoroughly, making sure you get into the center tube and all the grooves—this cake bakes beautifully, but bundts love to stick if you miss a spot.
2. Whisk the dry ingredients. In a large bowl, whisk the flour, baking powder, baking soda, cinnamon, and salt until the cinnamon is evenly distributed and you don’t see streaks of white flour.
3. Cream butter and sugar until airy. In another bowl, beat the softened butter with the sugar until it looks lighter in color and fluffy—this should take a couple of minutes and helps the cake bake up with a finer, lighter crumb.
4. Add the eggs and vanilla. Beat in the eggs one at a time, letting each one fully blend in before adding the next. Stir in the vanilla extract. If the mixture looks slightly curdled at any point, don’t worry—it will smooth out once the flour goes in.
5. Alternate flour and buttermilk. Add the dry mixture and buttermilk in alternating additions, mixing gently and stopping as soon as you no longer see dry flour. The batter should be thick, smooth, and spoonable—overmixing is what makes bundt cakes turn tough.
6. Layer for the swirl. Pour half the batter into the prepared bundt pan and spread it lightly so it’s even. Sprinkle with the cinnamon-sugar mixture, then spoon and spread the remaining batter over the top, covering the cinnamon layer.
7. Bake until set. Bake for 50–60 minutes, until the top looks set and a toothpick inserted into the cake comes out clean (a few moist crumbs are fine; wet batter is not). The cake should pull just slightly from the edges of the pan when it’s ready.
8. Cool, then invert. Let the cake cool in the pan before inverting onto a plate. Serving warm is lovely for a softer cinnamon aroma, but it also slices neatly at room temperature.

Tips for Best Results

• Grease every crevice of the bundt pan. The cinnamon-sugar layer can caramelize slightly, which makes sticking more likely if the pan isn’t well coated.
• Stop mixing as soon as the flour disappears. A thick, smooth batter is the goal—keep it gentle to protect that tender buttermilk crumb.
• Spread the first layer of batter evenly before sprinkling. It helps the swirl sit in a consistent band instead of sinking into one side.
• Watch the last 10 minutes of baking. Bundt cakes can go from perfectly tender to a bit dry if they stay in too long; pull it when the toothpick is clean and the top feels springy.
• Let it cool before flipping. Too-hot cake is fragile; a short rest helps it release cleanly and keeps the ridges intact. For more on how this site handles content and usage, you can read the terms and conditions.

Variations and Substitutions

If you only have salted butter, you can use it and keep the added salt on the lighter side (the cake should still taste balanced, not salty). You can also lean into the cinnamon by using a slightly heavier hand in the swirl—just keep the same layering method so the ribbon stays distinct.

How to Serve It

Slice it thick and serve slightly warm for the softest texture and the strongest cinnamon-vanilla aroma. I love it plain with coffee or tea, or at room temperature when you want the swirl to look extra clean and defined. For a simple presentation, dust the top lightly with a bit of sugar right before setting it on the table. For details on how site preferences are managed, you can review the cookie policy.

How to Store It

Store the cake covered at room temperature for a couple of days so it stays tender. For longer keeping, refrigerate it well covered and let slices come back to room temperature before serving for the best texture. You can also freeze slices tightly wrapped; thaw at room temp until the crumb is soft again.

Final Thoughts

If you’re craving an easy, cinnamon-swirled cake that looks impressive straight from the pan, this bundt delivers—tender, fragrant, and genuinely satisfying with nothing fussy about it.
