This homemade sourdough coffee cake is moist, light, and full of cozy flavor. It is made with sourdough discard, brown sugar, butter and much more goodness. Let's make this sourdough coffee cake together to enjoy in the mornings!

This morning, we woke up to a heavy snowstorm. It has continued on throughout the day and left us stuck inside with no place to go. This means that there is baking to be done and this sourdough coffee cake is on the list.
In the Winter, our bodies crave warm and cozy dishes. While nutrition is important, sometimes you just need a warm cake and a good cup of joe.
The creations of coffee cake actually go back to Germany. America was introduced to coffee cake through German immigration. There is a German word called "kaffeekuchen" which translates to coffee cake. There is also a German word called "streuselkuchen" which translates to a cake topped with streusel. These two words combined describe the characteristics of coffee cake.
Our coffee cake has the buttery, cinnamon and sugar streusel topping but the cake part is made with sourdough discard. Sourdough gives cakes an extra moist, soft, and fluffy texture. Traits that make up a good cake!
Now, grab your bowl and a whisk and let's make this coffee cake together!
How to Make Sourdough Coffee Cake
For the Cake


To start, in a small saucepan, melt ½ cup of butter. Once melted, pour it into a large mixing bowl along with the brown sugar and granulated sugar. Whisk well until smooth.
Next, whisk in the eggs one at a time until fully incorporated. Followed by the sourdough discard, vanilla extract, sour cream, and milk.


Then, on top of the wet ingredients, add the all-purpose flour, baking soda, baking powder, and cinnamon. Gently stir the pile of dry ingredients then fold them into the wet.
For the filling and topping
To a small bowl, add the cold and cubed butter, brown sugar, granulated sugar, cinnamon, and flour to a small bowl.

Using your hands or the back of a fork, mix the ingredients all together until a crumble like texture is formed.
To assemble
To assemble the cake, pour half the batter into a lightly greased 9x9 (or 8x8 but bake time will vary) baking dish. Then, sprinkle the middle of the cake with half of the filling/topping mixture. Add the rest of the batter into the dish, spreading around as best as possible. Lastly, finish off with the last of the topping.

Bake in a preheated 350-degree oven for 25 to 35 minutes or until a toothpick that is inserted comes out clean. I always like to check on the earlier side just to be sure.
Let cool completely before slicing and serving. Enjoy!
Tips
- Be careful to gently incorporate the dry ingredients and not to overmix. Overmixing can cause a dry cake.
- Using a dish smaller than an 8 by 8 will result in a dryer cake.
- This sourdough coffee cake can be made with sourdough discard or active starter.
- This coffee cake rises very high so keep that in mind when pouring in the batter. It will seem like not enough batter, but it will triple.

FAQs
Does sourdough coffee cake taste sour?
No, sourdough coffee cake does not taste sour. The sourdough starter in the coffee cake actually doesn't alter the taste at all, it just alters the texture. The sourdough gives it a fluffy, pillow, and extra moist texture.
Do I need active sourdough starter?
While this recipe is designed for sourdough discard, you can also use active starter. There are leavening agents in this recipe so active or discard will work.
Can I long ferment sourdough coffee cake?
Yes! Despite this recipe having leavening agents, you can long ferment this recipe overnight. Add all of the ingredients minus the eggs, baking soda, and baking powder. Then, after the fermentation, add the rest of the ingredients and bake as normal!
Why is my coffee cake dense?
Your coffee cake is dense for a few reasons. Some of them being the batter is overmixed, your discard was too thick, or your leavening agents were expired. The coffee cake should end up a light and fluffy texture. Something that is airy and not heavy.
