This buttery sour cream coffee cake has a thick cinnamon crumb topping that gets all golden and slightly crispy on top while the cake stays tender underneath. I first made this on a rainy Saturday morning when I wanted something warm and sweet to fill the kitchen with that cozy bakery smell, and it's been my go-to ever since. The sour cream keeps everything incredibly moist, and you only need one bowl for the batter, which makes cleanup so much easier than you'd think for something that tastes this good.
If you love tender breakfast cakes, you might also enjoy my Chocolate Chip Muffins or this quick Brownie in a Mug for those mornings when you need something sweet fast. This cake works beautifully for brunch gatherings or just a quiet weekday treat with your Banana Cobbler waiting in the wings for dessert.
What Makes This Sour Cream Coffee Cake So Special
Sour Cream Coffee Cake has this wonderful way of making any morning feel a little more special, even if you're just eating it in your pajamas at the kitchen counter. This version uses sour cream in the batter, which adds richness and keeps the crumb soft for days. The cinnamon topping has enough butter to form those satisfying clumps that get slightly crunchy in the oven.
I love that this Sour Cream Coffee Cake doesn't require any fancy techniques or hard-to-find ingredients. Everything comes together quickly, and the hardest part is waiting for it to cool down enough so you don't burn your tongue on the first bite.

Sour Cream Coffee Cake Ingredients
Here's everything for the crumb topping and the Sour Cream Coffee Cake itself.
See Recipe Card Below This Post For Ingredient Quantities
Cinnamon Crumb Mixture:
- Brown sugar: Packed dark or light brown sugar adds moisture and a deep, caramel-like sweetness to the topping.
- All-purpose flour: Spooned and leveled, helps form the crumbly texture.
- Ground cinnamon: Bring warmth and spice to balance the sweetness.
- Unsalted butter: Cold and cubed creates those pea-sized crumbs that bake up crispy and golden.
Cake:
- All-purpose flour: Spooned and leveled, forms the base structure of the cake.
- Baking powder: Helps the cake rise and stay light.
- Baking soda: Works with the sour cream to add extra lift and tenderness.
- Salt: Balances the sweetness and enhances all the other flavors.
- Unsalted butter: Softened to room temperature adds richness and helps create a tender crumb.
- Granulated sugar: Sweetens the cake and helps it brown nicely.
- Eggs: Large eggs at room temperature bind everything together and add moisture.
- Pure vanilla extract: Add warm, sweet depth.
- Full-fat sour cream: Room temperature makes the cake incredibly moist and adds a subtle tang.
- Milk: Kind works, thins the batter just enough for easy spreading.
Vanilla Icing (Optional):
- Confectioners' sugar: Sifted, creates a smooth, sweet glaze.
- Pure vanilla extract: Adds flavor.
- Heavy cream or milk: Thins the icing to drizzling consistency.
How to Make Sour Cream Coffee Cake
This comes together in simple steps, and you'll have it in the oven in about 20 minutes.
Preheat your oven: Set it to 350°F (177°C) and line an 8-inch square pan with lightly greased parchment paper, or just grease the pan directly.
Make the crumb topping: In a medium bowl, stir together the brown sugar, flour, and cinnamon. Use a pastry cutter, two forks, or your fingers to work the cold butter into the mixture until it looks like pea-sized crumbs. Pop the bowl in the fridge while you make the cake batter.
Mix the dry ingredients: In a large bowl, whisk the flour, baking powder, baking soda, and salt together, then set it aside.
Cream the butter and sugar: Using a handheld or stand mixer with the paddle attachment, beat the softened butter and granulated sugar on high speed for about 3 minutes until the mixture looks light and fluffy. Scrape down the sides of the bowl as needed.
Add the wet ingredients: Beat in the eggs and vanilla on medium-high speed until everything is combined. Mix in the sour cream. The batter will look a little lumpy at this point, and that's completely normal.
Combine everything: Add the flour mixture to the wet ingredients and beat on low speed until just combined. Pour in the milk and mix until the batter is smooth. It will be thick, almost like a very soft cookie dough.
Layer the cake: Spread half of the batter into your prepared pan. Sprinkle about 1 cup of the chilled cinnamon crumb mixture evenly over the batter. Spread the remaining batter on top as best you can (it's okay if it's not perfect). Sprinkle the rest of the crumb topping over everything.
Bake: Slide the pan into the oven and bake for 35 to 40 minutes. The cake is done when a toothpick poked into the center comes out clean. Let it cool in the pan on a wire rack for about 15 minutes.
Make the icing if using: Whisk together the confectioners' sugar, vanilla, and cream or milk until smooth. Drizzle it over the warm cake in whatever pattern makes you happy.
Serve: Slice the cake into squares right in the pan, or use the parchment paper to lift it out first. Serve it warm or at room temperature.
Store leftovers: Cover the cake tightly and keep it at room temperature for up to 3 days, or store it in the fridge for up to a week.
Smart Substitutions and Swaps
Sour cream: You can use full-fat Greek yogurt in the same amount. The texture will be slightly different but still delicious.
Milk: Any type works here, including almond milk, oat milk, or regular dairy milk.
Brown sugar in the topping: Light or dark brown sugar both work. Dark gives a deeper molasses flavor.
Butter: I don't recommend using margarine or oil for this recipe. The butter creates the best flavor and texture in both the Sour Cream Coffee Cake and the crumb topping.
Vanilla icing: Leave it off entirely if you prefer a less sweet cake, or use a simple dusting of powdered sugar instead.
Equipment For Sour Cream Coffee Cake
You'll need an 8-inch square baking pan for this recipe. A 9-inch pan will work, but the cake will be slightly thinner and may bake a bit faster, so start checking around 30 minutes.
A pastry cutter makes quick work of the crumb topping, but two forks or even your hands will do the job. I actually prefer using my hands because I can feel when the butter is worked in just right.
A handheld or stand mixer makes creaming the butter and sugar much easier and gets more air into the batter. You could do it by hand with a wooden spoon, but it will take some arm strength and a few extra minutes.
Use parchment paper if you want to lift the Sour Cream Coffee Cake out of the pan for cleaner slicing. Otherwise, greasing the pan works fine, and you can just cut squares directly in the pan.
How to Store Sour Cream Coffee Cake
This Sour Cream Coffee Cake keeps beautifully at room temperature for up to 3 days when covered tightly with plastic wrap or stored in an airtight container. The sour cream keeps it moist, so it doesn't dry out quickly like some cakes do.
You can also refrigerate it for up to a week. I actually like eating it cold straight from the fridge, especially in the summer.
To reheat, warm individual slices in the microwave for about 15 seconds. The crumb topping softens slightly when reheated, but it still tastes wonderful.
Serving Suggestions
This Sour Cream Coffee Cake is lovely on its own, but here are a few ways to make it even better:
Serve it with a hot cup of coffee or tea for a classic pairing. The slight tang from the sour cream balances perfectly with the bitterness of coffee.
Add a dollop of whipped cream or a scoop of vanilla ice cream if you're serving it as dessert. The cold cream against the warm Sour Cream Coffee Cake is such a nice contrast.
For a fancier brunch presentation, dust the top with extra cinnamon or powdered sugar and serve it alongside fresh berries.
Pair it with savory breakfast dishes like my Loaded Meat Pie for a complete spread, or keep it simple with just scrambled eggs on the side.
Expert Tips
Bring your ingredients to room temperature. Cold eggs and sour cream don't blend as smoothly into the batter, which can affect the texture. Set them out about 30 minutes before you start baking.
Don't overmix the batter. Once you add the flour mixture, mix just until you don't see any dry streaks. Overmixing develops the gluten and can make the Sour Cream Coffee Cake tough instead of tender.
Keep the butter cold for the topping. Cold butter is key to getting those nice crumbly pieces. If your kitchen is warm, stick the bowl in the fridge while you make the batter.
Check for doneness a few minutes early. Ovens vary, so start testing with a toothpick around 35 minutes. The center should look just set, and the toothpick should come out clean or with just a few moist crumbs.
Let it cool before icing. If you add the icing while the Sour Cream Coffee Cake is too hot, it will melt and soak in instead of sitting on top in a pretty drizzle. Wait at least 15 minutes after baking.
FAQ
What does sour cream do to coffee cake?
Sour cream adds moisture and richness to the cake, and the acidity helps tenderize the crumb by reacting with the baking soda. It also gives the cake a subtle tangy flavor that balances the sweetness. My mom always says sour cream is the secret ingredient that keeps cakes soft for days.
What's the secret to a tender sour cream cake?
The secret is not overmixing your batter once you add the flour. Mix just until combined, and make sure your sour cream and eggs are at room temperature so they blend smoothly. Cold ingredients can cause the batter to seize up and not incorporate well.
What is the secret to a good coffee cake?
A good Sour Cream Coffee Cake has a tender, moist crumb and a generous amount of topping. Use real butter for the best flavor, don't skimp on the cinnamon, and let the cake cool slightly before cutting so the crumbs set. The balance between cake and topping is everything.
What are common coffee cake mistakes?
The biggest mistake is overbaking, which dries out the Sour Cream Coffee Cake. Another common issue is using melted butter instead of softened butter in the cake batter, which changes the texture. Also, don't rush the cooling time. If you cut it too soon, the cake can fall apart, especially with all that crumb topping on top.
