What Is Coffee Cake?
Despite the name, traditional coffee cake does not actually contain any coffee. This breakfast staple is a lightly sweetened single-layer cake commonly topped with a sweet streusel topping made from flour, butter, and sugar. This cake is often spiced or filled with a variety of fruit, nuts, or even chocolate.
So, why is it called coffee cake if it doesn’t have any coffee in it? This classic breakfast cake got its name because it’s meant to be enjoyed alongside coffee or tea in the morning. Not only is this the perfect dish for your next breakfast or brunch party, but it also makes a great dessert or afternoon snack!

Ingredients
for the cake batter
Butter: Either salted or unsalted butter can be used in this recipe. If you use unsalted, add an extra pinch of salt to your cake batter, filling, and topping.
Granulated sugar: Granulated sugar is this cake's main source of sweetness. It adds moisture and softness to the cake.
Pure vanilla extract: Vanilla adds great flavor to the cake and the glaze. You can easily swap out the vanilla for another flavor if desired.
Egg: The egg provides structure and assists with leavening to ensure the cake rises properly. It also contributes additional flavor and color to the cake.
Sour cream: Sour cream makes for a super moist coffee cake! It also adds a tanginess that pairs well with the sweet cinnamon and nutty flavors. If you don't have any sour cream on hand, plain greek yogurt works as a substitute.
All-purpose flour: We use all-purpose flour but finely ground whole wheat flour would also work here.
Baking powder: Baking powder is the leavening agent in this sour cream coffee cake recipe. It helps the cake rise and keeps it light and airy.
Salt: Salt enhances all of the flavors in this cake. It also balances out the sugar so it’s not too sweet.
Milk: We use 2% milk here but you can substitute your milk of choice (nonfat milk is not recommended). Milk adds moisture to the cake and contributes to the overall color and flavor.
for the filling & topping
Cinnamon: You can’t have a cinnamon walnut coffee cake without the cinnamon. This cake has a cinnamon filling as well as a cinnamon streusel topping.
Brown sugar: Brown sugar adds sweetness and creates caramelization in the filling and streusel layers.
Nutmeg: Nutmeg contributes a warm spice and compliments the cinnamon flavor.
Walnuts: Using toasted walnuts in this coffee cake is optional, but recommended. Toasting the walnuts beforehand intensifies the rich nuttiness and adds a bit of crunch.
for the glaze
Powdered sugar: Powdered sugar is the main component of the sweet glaze that goes on top of the cake.
How to Make This Recipe
Follow these steps to make this delicious coffee cake.
prepare the ingredients
Start by removing the butter, milk, egg, and sour cream from the refrigerator. For this recipe, it is best if these ingredients are at room temperature when added to the batter. Here’s why this is important:
- Consistency is key here and using cold ingredients can alter the overall outcome of your coffee cake.
- Room temperature ingredients (e.g. milk and eggs) blend much more easily into batter than cold ones. When these ingredients are more evenly blended, more air is trapped in the batter, resulting in a lighter texture.
Here are some easy ways to soften butter quickly!
Next, toast the walnuts. While this step is optional, we highly recommend it for more flavor in your cinnamon walnut coffee cake.
To toast the walnuts, preheat the oven to 325°F and place the rack in the middle of the oven. Toast them on a lined baking sheet until they are golden brown (8-12 minutes) and then let them cool.
make the batter
In a large bowl, cream together the butter and the sugar, scraping down the sides of the bowl as needed. With the mixer on medium speed, mix in the egg, vanilla, and sour cream. A stand mixer makes this process super simple but any electric mixer works great.
In a separate bowl, combine the dry ingredients by whisking together the flour, baking powder, and salt.
Add half of the flour mixture to the batter and mix on low speed just until combined. Then, add the milk and continue to mix until it is almost fully incorporated. Add the remainder of the flour mixture, mix just until fully combined, and set it aside.
make the filling
In a food processor, add all of the filling ingredients except for the walnuts and blend until it’s fully mixed with a sandy texture. Then, add in the walnuts and pulse until they are finely chopped. Set the filling mixture aside.
make the topping
To make the streusel topping, add all of the topping ingredients to the food processor. Pulse until the ingredients are combined but appear crumbly with some larger chunks. Set it aside.
assemble, bake, and glaze
Preheat the oven to 350°F and lightly grease a 9x9 baking pan. Pour half of the cake batter into the prepared pan.
Add a generous amount of the cinnamon filling over the top of the batter. Pour the rest of the batter on top of the filling, spreading evenly. Finally, sprinkle the streusel over the top of the cake batter.
Place the cake on the middle rack in the preheated oven. Bake for 45-50 minutes or until the cake tests done with a toothpick. Remove from the oven and let cool.
While the cake is cooling, start on the glaze. In a small bowl, combine the powdered sugar, milk, and vanilla and stir until smooth. Once the cake is completely cooled, drizzle the glaze on top of the cake.
Recipe Tips and Tricks
Use room temperature ingredients. All of the ingredients in this recipe should be at room temperature except the cold butter in the streusel topping. This ensures the ingredients blend together more easily.
Toast the walnuts. It’s a little extra work but it’s definitely worth it. Toasting the walnuts brings out the natural flavors and adds a nice golden color and slight crunchiness.
Spoon and level the flour. To ensure you don’t overmeasure the flour, fluff the flour with a spoon. Then, spoon the flour into the measuring cup and level the top with a knife. Adding too much flour will make your cake dry.
Use the toothpick method. Check the center of the cake with a toothpick to make sure it’s done before removing it from the oven. When the cake is done, you should see small crumbs on the toothpick when it comes out.
How To Store Leftovers
One great thing about this cinnamon walnut coffee cake is that it stores really well! It can be stored in an airtight container at room temperature for up to 3 days.
For longer storage, you can keep it in the freezer for up to 2 months. Let it thaw to room temperature before serving.
