This cinnamon coffee cake recipe with sour cream and brown sugar streusel is outrageously delicious! It’s moist, tender, and perfect with coffee or dessert!
I genuinely cannot wait for you to make this homemade coffee cake! It’s so good! The sour cream batter is super simple to make. Then we swirl in the most deliciously flavorful brown sugar streusel made with lots of cinnamon.
When testing this recipe, I had a hard time stopping myself from eating all the streusel (it’s so much more flavorful than your traditional streusel). For more recipes like this one, I love this lemon blueberry cake, our popular carrot cake, and this incredible apple almond coffee cake.
Key Ingredients
- Butter and Sour Cream: Butter keeps our coffee cake moist and flavorful. For even more moisture and flavor, we add sour cream. Thanks to sour cream’s higher fat content, our coffee cake stays light, airy, and moist. It also adds a subtle tang to the cake, which works beautifully with the brown sugar streusel. While I love sour cream for this coffee cake, you can substitute it with plain yogurt without any changes.
- Eggs: These add structure to the cake, and the fat from the yolks adds to its tenderness. I use 2 eggs and 1 egg yolk and do not recommend substituting them with egg replacers.
- Flour, Baking Powder, and Baking Soda: I use all-purpose flour, although I imagine your favorite gluten-free blend will work in this recipe. The baking powder and baking soda help the cake brown and rise.
- Sugar: I use granulated and brown sugar in this cake and think you should, too. The combination improves the texture and flavor. Then, I use 100% brown sugar for the streusel to taste rich and caramel-like.
- Vanilla and Almond Extract: The flavor of this coffee cake is much better when you combine vanilla extract with a little almond extract in butter cakes. Your cake will taste like it came from a fancy bakery. You won’t tell if almond extract is there, but the cake will taste amazing.
- Spices: We use a lot of cinnamon in this recipe and don’t apologize for it (just like when making homemade cinnamon rolls). In addition to the cinnamon, I love a little nutmeg and salt.
- Molasses: This is my secret for the best cinnamon streusel! Molasses makes it much richer and more flavorful than if you make it without. I only use a tablespoon, so I understand not wanting to buy a new jar just for this recipe (it still tastes great without it), but if you have some on hand, use it! It makes it taste so good!
- Walnuts (optional): With all the richness from the butter and the streusel, I love adding some texture. Walnuts are great, but other nuts, like sliced almonds or pecans, would be great.
- Maple Butter Glaze (optional): The cake is perfectly delicious without anything, but if you want to take it to the next level, make our maple glaze with powdered sugar, maple syrup, butter, and milk. It’s amazing!
How to Make Cinnamon Coffee Cake
While the ingredient list seems long, I promise this cake recipe is easy to make! You’ll start with the cake batter. I use a hand mixer to beat butter and sugar until light and fluffy. Then I add the eggs, vanilla, and almond extract. Mix that with your dry ingredients, and you’ve got your batter.
Before baking, we want to add our streusel to the cake. So mix all the streusel ingredients (it only takes a spoon), then spread half the coffee cake batter in your baking pan, add a bunch of crumbles of the streusel over the batter, and then spoon on the remaining batter. Add some more streusel, and you will be ready to bake.
Finally, as your cake cools, you can make the maple drizzle (optional, but so good). When the cake is thoroughly cooled, drizzle it all over, cut yourself a slice, and enjoy!

Our sour cream cinnamon streusel coffee cake is outrageously good. We make the batter with sour cream, butter, and vanilla, then add brown sugar cinnamon streusel. We also add a maple butter drizzle after baking, which is delicious, but you can leave the cake plain or add a dusting of powdered sugar on top instead.

You Will Need
For Coffee Cake
12 tablespoons (170g) unsalted butter, at room temperature, 1 ½ sticks
2 large eggs, at room temperature
1 large egg yolk, at room temperature
2 ¼ cups (290g) all-purpose flour
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon fine sea salt
3/4 cup (150g) brown sugar
1/2 cup (100g) granulated sugar
1 tablespoon pure vanilla extract
3/4 teaspoon almond extract
1 ¼ cups (280g or 10 oz) sour cream
For Streusel
8 tablespoons (115g) unsalted butter, melted, 1 stick
1 tablespoon molasses
1 tablespoon ground cinnamon
1/4 teaspoon fine sea salt
1/4 teaspoon grated nutmeg
1/3 cup (65g) brown sugar
1/4 cup (50g) granulated sugar
1 1/3 cups (170g) all-purpose flour
2/3 cup (70g) walnuts, chopped, optional
For Maple Butter Drizzle
2 tablespoons (30g) unsalted butter
1 tablespoon pure maple syrup
1/2 cup (55g) powdered sugar
1 tablespoon milk
Pinch fine sea salt
Directions
- Make Batter
1Center a rack in the oven and preheat to 350°F (176°C). Line a 9-inch by 13-inch baking pan with parchment paper and lightly spray with nonstick cooking spray.
2Sift or whisk the flour, baking powder, baking soda, and salt in a medium bowl.
3In a large bowl, beat 12 tablespoons of room-temperature butter, brown sugar, and granulated sugar with an electric mixer on high speed until light and fluffy, 2 to 3 minutes. (Alternatively, add butter and sugars to the bowl of a stand mixer and mix on medium speed until fluffy.)
4Beat in the eggs, one at a time, then add the egg yolk, vanilla, and almond extract.
5With the mixer on low speed, add one-third of the flour mixture to the batter. When it’s mostly combined, add another third and mix until almost no flour remains. Add the sour cream and mix just until smooth, then finish by adding the remaining flour to the batter and beat until just combined. Finish stirring with a spatula to be sure the batter is completely blended.
- Make Streusel
1In a medium bowl, whisk the melted butter with the molasses, cinnamon, nutmeg, and salt until well blended. Add the brown sugar, granulated sugar, and flour. Stir until a soft dough forms. Stir in nuts (optional).
- Bake Cake
1Spread about half of the cake batter into the prepared baking pan. It’s okay if the batter doesn’t spread all the way to each corner. Scatter half of the streusel over the cake batter. (I like scattering larger pieces and smaller crumbles.)
2Spoon dollops of the remaining batter on top of the streusel and then spread into an even layer. It’s okay if some of the streusel from below gets mixed into the top layer of batter.
3Finish with the remaining streusel on top. It might look like there isn’t enough batter, but don’t worry, the cake rises quite a bit, while some of the streusel will fall into the cake.
4Bake the coffee cake until it starts pulling away from the pan’s sides and is springy. A cake tester or toothpick inserted into the middle should come out mostly clean, 40 to 50 minutes.
5Cool the cake in the baking pan for 10 minutes, then transfer it to a wire rack and cool it completely.
- To Finish
1Melt the butter in a small bowl, and then stir in the maple syrup. Whisk in the powdered sugar, milk, and salt. The mixture should be the consistency of thick syrup and easily drizzled. If it’s too thin, add a bit more powdered sugar. If it is too thick, add a little more milk.
2Drizzle the maple butter frosting over the cake, then set aside for 5 minutes or until it hardens slightly. Cut the cake into 12 large slices or 24 smaller slices, and then serve.
Adam and Joanne’s Tips
- Measuring the flour: Flour should be spooned and leveled in the measuring cup. Use a spoon to add the flour to the cup, and then use a flat edge to scrape the top of the cup. This method ensures you do not add too much flour to the batter.
- Room temperature butter & eggs: The butter and eggs must be room temperature for this cake recipe. If the eggs are too cold, the chill from the eggs will make your batter lumpy since they will chill the butter, and it will start to harden. It’s best to leave butter out in advance at room temperature. Place eggs into a bowl with lukewarm water for 5 to 10 minutes to quickly bring them to room temperature. (It’s okay if the sour cream is cooler since we add it at the end, but I prefer to take it out before making the cake recipe.)
- Storing: Place in an airtight container and store at room temperature for up to 2 days, store in the fridge for up to 5 days, or freeze for up to 3 months.
