How to make Cinnamon Swirl Bundt Cake

You’ll Need

For the Cinnamon Swirl Bundt Batter

3 cups (360 g) all-purpose flour, spooned and leveled

2 teaspoons baking powder

1/2 teaspoon baking soda

1 teaspoon fine salt

1 cup (225 g) unsalted butter, softened

1 1/2 cups (300 g) granulated sugar

1/2 cup (110 g) light brown sugar, packed

4 large eggs, room temperature

2 teaspoons vanilla extract

1 cup (240 g) full-fat sour cream, room temperature

1/2 cup (120 ml) milk (whole or 2%), room temperature

For the Brown Sugar Cinnamon Swirl

3/4 cup (150 g) light brown sugar, packed

2 1/2 tablespoons ground cinnamon

1 tablespoon all-purpose flour

Optional: 1/4 teaspoon ground nutmeg or cardamom for a little extra warmth

Optional: 1/2 cup finely chopped pecans or walnuts

For the Simple Vanilla Glaze

1 1/2 cups (180 g) powdered sugar, sifted

2–3 tablespoons milk or cream

1 teaspoon vanilla extract

Pinch of salt

Optional: 1/4 teaspoon ground cinnamon for a cinnamon glaze

For the Pan

Softened butter or cake goop (equal parts oil, flour, shortening) for greasing

2–3 tablespoons granulated sugar or very fine dry breadcrumbs for dusting the pan

The moisture trifecta here is butter + a little brown sugar for flavor + sour cream for that tender, coffee-cake texture. Sour cream cinnamon bundt cake recipes are famous for staying moist and fluffy even on day three this follows the same logic.

The brown sugar cinnamon swirl is simple but powerful: brown sugar brings a caramel note, cinnamon brings that warm bakery smell, and a spoonful of flour keeps the swirl from sinking or turning greasy. Nuts are optional, but they add a subtle crunch that makes this feel extra coffee-cake-y.

Step-by-Step Instructions

Before you start:
Preheat your oven to 350°F (175°C). Place a rack in the lower-middle of the oven. Generously grease a 10–12 cup Bundt pan with softened butter or cake goop, making sure to get into every ridge and the center tube, then dust with sugar or fine breadcrumbs, tapping out the excess. This combo makes a beautiful crust and helps prevent sticking.

1. Mix the cinnamon swirl

In a small bowl, stir together the brown sugar, cinnamon, flour, and nutmeg/cardamom if using. Stir in the chopped nuts if you’re using them. Set aside this is your cinnamon roll-style filling.

2. Whisk the dry ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures the leavening is evenly distributed so your Bundt rises evenly.

3. Cream butter and sugars

In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together with an electric mixer on medium-high until light and fluffy, 3–4 minutes. The mixture should look creamy and slightly lightened in color — this step gives you that tender Bundt crumb.

4. Add eggs and vanilla

Beat in the eggs one at a time, mixing well after each addition and scraping down the bowl as needed. Add the vanilla and mix until combined. If the batter looks a bit curdled, don’t panic; the sour cream and flour will bring it back together.

5. Add sour cream and milk

On low speed, mix in the sour cream until smooth. With the mixer still on low, add the milk in a slow stream just until incorporated. The batter might look slightly loose that’s okay.

6. Add the dry ingredients

Sprinkle about half of the flour mixture over the batter and mix on low just until almost combined. Add the rest of the flour and mix or fold by hand until no dry streaks remain. Avoid overmixing; you want a thick, velvety batter, not a tough cake. Scrape the bowl well so no butter pockets lurk at the bottom.

7. Layer the batter and swirl

Spoon about one-third of the batter into the prepared Bundt pan and spread it into an even layer. Sprinkle half of the cinnamon swirl mixture evenly over the batter.

Add another third of the batter on top (dollop it around, then gently spread to cover the cinnamon layer), then sprinkle the remaining cinnamon swirl. Finish with the last third of batter, smoothing the top. You can gently run a butter knife through the batter in a loose “S” pattern if you want a more marbled look, but don’t over-swirl or you’ll lose the defined ribbon.

Tap the pan firmly on the counter 2–3 times to release large air bubbles.

8. Bake

Bake at 350°F for 45–55 minutes, until the cake is deep golden and a skewer inserted into the center comes out with just a few moist crumbs attached but no wet batter. If the top is browning too quickly towards the end, tent it loosely with foil. Start checking around 42–45 minutes; Bundt pans and ovens vary.

9. Cool and unmold

Set the cake on a wire rack and cool in the pan for 10–15 minutes not less, not much more. This window lets the crumb set without the sugars sticking firmly to the pan. Place your serving plate over the Bundt, use oven mitts to grip pan and plate together, and confidently flip in one motion. Gently lift the pan; your cinnamon swirl Bundt cake should drop out in one gorgeous piece. If it resists, give the pan a few firm taps and a gentle jiggle.

Let the cake cool completely before glazing.

10. Glaze

In a medium bowl, whisk together powdered sugar, 2 tablespoons milk, vanilla, salt, and cinnamon if using. Add more milk a teaspoon at a time until the glaze is thick but pourable you want it to slowly drip, not run straight off.

Set the cooled cake on a rack over a sheet of parchment and drizzle the glaze over the top, letting it run down the ridges. Let it set for 15–20 minutes before slicing.

Tips for Success

Grease the pan like you mean it. Cinnamon sugar can be a little sticky where it meets the pan. Use plenty of softened butter or cake goop, and consider dusting with sugar or fine breadcrumbs instead of flour for a crisp, sweet crust and easier release.

Don’t rush the creaming step. Those 3–4 minutes of beating butter and sugar build air into the batter, which gives you that tender bundt crumb instead of a dense brick. If the mixture still looks grainy, keep going until it’s fluffy.

Stick to the cool-10–15 rule. Turning the cake out too hot or too cold is how you get breakage and sticking. Set a timer for 10 minutes after it comes out, check that the edges are just pulling away, then invert. If you forget and it sticks, gently warm the pan base with a hot towel or brief hot-water dip to loosen the sugars.

Balance the swirl. Too much cinnamon sugar in one layer can create a heavy seam that sinks. Spreading the swirl into two thinner layers gives you a pretty ribbon and keeps the cake structurally sound.

Think “bake once, snack all week.” This cinnamon coffee cake Bundt is ideal for slicing as needed. Keep it covered at room temp for a couple of days, then move to the fridge or freezer for longer storage it will still taste great after a few days of busy-mom life.

Variations

Cream cheese icing cinnamon roll Bundt. Skip the vanilla glaze and instead top with a thick cream cheese icing (cream cheese, butter, powdered sugar, vanilla, and a splash of milk). The cake becomes a full-on cinnamon roll Bundt cake situation — amazing for brunch or holidays.

Cinnamon streusel Bundt. Mix 1/4 cup melted butter and 1/2 cup flour into the cinnamon swirl mixture to make a crumbly streusel, and sprinkle some over the top of the batter in the pan. You get cinnamon streusel bundt cake vibes with crunchy pockets around the edges.

Chai-spiced swirl. Add cardamom, allspice, and a pinch of cloves to the cinnamon mixture for a chai twist. The cake turns into a chai cinnamon swirl Bundt that pairs amazingly with a latte or chai tea.

Lightened-up weekday version. Swap half the sour cream for plain Greek yogurt and skip the glaze, just dusting with powdered sugar. Still moist and cozy, but a bit more “breakfast” and a bit less “frosting-forward dessert.”

Breastfeeding & Postpartum Friendly Options

Snack-friendly slices. After the cake cools, slice it into thinner wedges, wrap individually, and freeze. You can grab one slice at a time, microwave for 10–15 seconds, and have a soft, cinnamon-y snack for late-night feeds.

Gentler sweetness. Reduce the glaze or skip it entirely if ultra-sweet desserts don’t sit well right now. The cake itself has just enough sweetness and cinnamon comfort to feel like a treat with a mug of decaf or herbal tea.

What to Serve With Cinnamon Swirl Bundt Cake

This cinnamon swirl Bundt cake is already giving big coffee cake energy, so you don’t need much else. A few simple sides turn it into a full breakfast, brunch, or dessert spread.

Fresh fruit: berries, orange slices, or apple wedges

Soft-scrambled eggs or a simple egg bake for a brunch table

Lightly sweetened whipped cream or a dollop of Greek yogurt

Hot coffee, chai, or a latte for adults

Cold milk or hot cocoa for kids

Leftover slices also tuck perfectly into lunchboxes alongside fruit and a cheese stick for a fun surprise.

Storage & Reheat

Once the cinnamon bundt cake is completely cool and glazed, cover it tightly with plastic wrap or store it in a cake keeper at room temperature for 2–3 days. Thanks to the sour cream, it stays plush and moist instead of drying out like some pound

For longer storage, refrigerate (well wrapped) for up to 5 days. Let slices come to room temperature before serving so the crumb softens and the buttery vanilla flavor shines.

To freeze, you can wrap the whole, unglazed cake tightly in plastic and foil, or freeze individual glazed slices. The whole cake keeps 2–3 months; thaw overnight at room temp and glaze before serving. Slices can be thawed on the counter for 30–45 minutes or given a 10–15 second microwave warm-up for a just-baked feel.

FAQs

1. Can I make this cinnamon swirl Bundt cake ahead of time?
   Yes, it’s actually better the next day. Bake, cool, and glaze the cake, then cover it and keep at room temperature for up to 2–3 days, or refrigerate for up to 5 days. The sour cream coffee cake style crumb stays moist, and the cinnamon flavor deepens, making it a great make ahead cinnamon coffee cake bundt for brunch or gatherings.
   
2. How do I keep my cinnamon Bundt cake from sticking to the pan?
   Use a good nonstick Bundt pan, grease every single ridge with softened butter or cake goop, and dust the pan with sugar or fine crumbs. After baking, let the cake cool in the pan for about 10–15 minutes, then invert while it’s still warm so the sugars haven’t fully hardened onto the pan. If it still sticks, gently warm the outside of the pan with a hot towel or short hot-water dip to loosen it.
   
3. Can I bake this in a different pan if I don’t have a Bundt?
   Yes. You can bake it in a 9×13-inch pan as a cinnamon swirl coffee cake; start checking for doneness around 35–40 minutes. The texture will be very similar, just without the classic Bundt shape. Line the pan with parchment for easy removal and slice into squares instead of wedges.
   
4. Can I make this cinnamon swirl Bundt cake dairy-free?
   You can swap the butter for a dairy-free margarine or neutral oil and use a thick plant-based yogurt and non-dairy milk in place of sour cream and milk. The flavor and crumb will be slightly different, but the easy cinnamon bundt cake recipe method stays the same. Just keep an eye on baking time, as some dairy-free fats brown faster.
5. Can I add more mix-ins like nuts or chocolate chips?
   Absolutely. You can fold up to 1 cup of chopped nuts or mini chocolate chips into the batter without changing the structure. You can also add nuts to the cinnamon swirl for more crunch. Just avoid adding too many heavy mix-ins or the swirl can sink, and your moist cinnamon swirl Bundt cake may bake unevenly.
