Cinnamon Swirl Coffee Cake is a sweet, soft treat that’s perfect for breakfast or an afternoon snack. It’s got a tender crumb with a moist texture, and the star of the show is the cinnamon-sugar swirl that winds through every bite. A light crumbly topping adds a little extra crunch and sweetness that makes it so easy to love.
I always enjoy this coffee cake warm, right out of the oven, with a fresh cup of coffee or tea. There’s something about the cinnamon aroma filling the kitchen that feels so comforting and like a little gift to yourself. One of my favorite things is how the cinnamon swirl surprises you as you slice into the cake – it feels like a sweet secret hiding inside.
This cake is easy to share with friends or family, and it never lasts long in our house. I like to serve it slightly warm and sometimes spread a little butter on top for an extra cozy touch. It’s simple enough to make for a cozy morning or a casual get-together, and it always makes the day feel a little brighter.
Key Ingredients & Substitutions
All-purpose flour: This gives the cake structure and tenderness. You can swap it for gluten-free flour blends if needed—just make sure they’re good for baked goods.
Butter: Provides richness and moisture. If you prefer, try using softened coconut oil or a neutral vegetable oil for a dairy-free version.
Sour cream or yogurt: Adds moisture and a slight tang to keep the cake soft. Greek yogurt works well too and adds protein.
Cinnamon: The star of the swirl and topping! Freshly ground cinnamon will give your cake the best flavor, but pre-ground is fine too.
Sugar: Granulated sugar sweetens the batter, while brown sugar in the swirl gives that deep, molasses note. You can use coconut sugar for a lower glycemic index alternative.
How Do You Get a Perfect Cinnamon Swirl and Crumb Topping?
The goal is to create clear cinnamon layers and a crunchy crumb topping without mixing it all into the batter. Here’s how:
- After spreading half the batter, sprinkle the cinnamon-sugar mixture evenly—avoid clumps, or the swirl won’t look nice.
- Pour the rest of the batter carefully over the cinnamon layer. Spread gently to keep layers distinct.
- For the crumb topping, mix melted butter with flour, sugar, and cinnamon until crumbly but manageable.
- Sprinkle this topping evenly on the very top before baking.
- Bake at 350°F until a toothpick comes out clean—this ensures the batter is fully cooked but still moist.
Taking these steps helps keep the swirl defined and provides that classic crumbly finish everyone loves.
Equipment You’ll Need
- 9×13-inch baking pan – perfect size for even baking and easy slicing.
- Mixing bowls – you’ll need at least two for batter and cinnamon mixture.
- Hand mixer or stand mixer – makes creaming butter and sugar much quicker and smoother.
- Measuring cups and spoons – important for accurate ingredient amounts.
- Spatula – great for spreading batter evenly without breaking the layers.
- Wire cooling rack – lets the cake cool evenly without getting soggy.
Flavor Variations & Add-Ins
- Add chopped nuts like walnuts or pecans to the crumble topping for a crunchy texture contrast.
- Mix mini chocolate chips into the batter or swirl for a sweet twist that pairs well with cinnamon.
- Swap sour cream for Greek yogurt to add a tangy flavor and extra moisture.
- Stir in ½ cup of fresh or frozen berries for bursts of fruity flavor inside the cake.

How Much Time Will You Need?

Step-by-Step Instructions:
1. Prepping the Oven and Ingredients:
Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan to keep your cake from sticking. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt – this helps your dry ingredients blend smoothly.
2. Making the Batter:
In a large bowl, beat the softened butter and granulated sugar together until fluffy and light—this usually takes about 3-4 minutes. Then add eggs one at a time, mixing well after each. Stir in the vanilla extract. Next, alternate adding the dry flour mixture and the sour cream into the butter mixture, starting and ending with the dry ingredients. Mix just until combined to keep your cake tender.
3. Creating the Cinnamon Swirl and Topping:
Put half of your batter into the prepared pan and spread it evenly. In a separate small bowl, mix the brown sugar and cinnamon together. Sprinkle half of this cinnamon mixture evenly over the batter. Carefully pour the remaining batter on top and gently spread it. For the topping, mix the melted butter, flour, granulated sugar, and the remaining cinnamon-sugar mixture until crumbly. Sprinkle this crumb topping evenly over the cake.
4. Baking and Cooling:
Bake your coffee cake for 40-45 minutes or until a toothpick inserted into the center comes out clean. Once baked, remove the cake from the oven and let it cool in the pan on a wire rack. When cool enough, cut into squares and enjoy, warm or at room temperature, with your favorite coffee or tea.
Can I Use Greek Yogurt Instead of Sour Cream?
Yes! Greek yogurt is a great substitute and adds a nice tang while keeping the cake moist. Use the same amount and make sure it’s plain, unsweetened yogurt.
How Should I Store Leftover Coffee Cake?
Store leftovers in an airtight container at room temperature for up to 2 days, or in the fridge for up to a week. Warm slices slightly in the microwave before serving to refresh the texture.
Can I Freeze This Coffee Cake?
Absolutely! Wrap cooled cake tightly in plastic wrap and then foil before freezing. It keeps well for up to 3 months. Thaw overnight in the fridge and warm before serving.
How Do I Get a Well-Defined Cinnamon Swirl?
To keep the swirl distinct, sprinkle the cinnamon-sugar mixture evenly over half the batter before adding the remaining batter on top. Avoid mixing layers and spread gently to preserve the layers while baking.
