Sourdough Coffee Cake
This sourdough coffee cake has a perfectly sweetened ribbon of cinnamon sugar between layers of moist vanilla cake. It's topped with a nutty pecan crumble that get's better with every bite!
Homemade coffee cake is the perfect way to enjoy your morning cup of coffee!

You guys are going to love this sourdough discard recipe! It is my version of a classic coffee cake, sourdough style of course!
Coffee cake is defined as any cake flavored with or intended to be eaten with coffee. Traditional coffee cake recipes you find in the States don't actually have coffee in the ingredients at all.
Instead you'll find a delightful mixture of brown sugar, cinnamon and nutty pecans combined with a vanilla cake base.
The result is a perfectly sweetened, cinnamon spiced breakfast cake that begs to be eaten alongside a strong cup of coffee. The two really are a perfect match!

Step by step instructions
There are three separate layers to this cake, but don't worry, it's a cinch to get it into the oven!
Preheat your oven to 350ยฐF (175ยฐC) and lightly grease an 9" x 9" metal baking pan with butter or cooking spray.
1. Pecan Crumble Layer:
- Melt the butter in a bowl and stir in the light brown sugar and cinnamon until throughly mixed and smooth.
- Add the flour and pecans and stir again until the mixture comes together into a big clumpy mass. Set it aside and let it cool.
2. Cinnamon Sugar Layer:
- In a small bowl, mix the light brown sugar, cinnamon and flour together with a fork and set aside.

3. Cake Batter Layer:
- In a large mixing bowl, use a spatula to cream the butter, light brown sugar and granulated sugar until smooth.
- Add the eggs, vanilla extract, sour cream, sourdough starter discard, milk, salt and baking powder to the bowl and stir until combined.
- Add the flour and mix until ingredients are fully incorporated.
Assembly:
- Pour half of the cake batter into the greased baking dish and sprinkle the cinnamon sugar mixture evenly across the surface of the batter.
- Carefully pour the remaining batter over the cinnamon sugar mixture. Use an offset spatula to gently spread the batter evenly.
- Break up the crumble topping with your fingers and sprinkle evenly over the top.
- Bake for 40-45 minutes or until a toothpick inserted in the middle comes out clean.

Let the sourdough coffee cake cool for 10-15 minutes before slicing and serve warm!
How to measure flour without a scale
Don't have a kitchen scale to measure flour?
Use the scoop and level technique to measure your flour if you do not have a kitchen scale. To do this, use a spoon to fluff up the flour in the bag. Use a spoon to scoop the flour into a measuring cup until it is heaped on top. Take a butterknife and level off the top. This should give you the most accurate measurement for flour.
Because flour is measured by weight in these recipes, if the flour is scooped straight out of the bag with the measuring cup, there will be more flour than called for in the recipe.
How to store leftovers
Leftovers can be stored at room temperature in a container for up to 2 days or refrigerated for up to a week.
To freeze leftovers, let the cake cool completely and wrap individual squares with plastic wrap. Place the wrapped squares in a freezer-safe container for up to 3 months.
To reheat the coffee cake, let thaw first. Warm in the microwave in 15 second increments. Alternatively, you can place a piece on a parchment lined baking sheet and warm in the oven at 350 degrees F for 10 minutes or until heated through.

Hi! Have you tried this with an overnight ferment?
Thanks!
my cake came out pretty dense. what did I do wrong?
Hi Alanna, sourdough coffee cake is meant to be more dense than regular cake, but still moist.
Getting ready to make, quick question salted or unsalted butter?
Either will work!
hi! how long would you recommend baking if using a glass baking dish?
I would check it around the 60 minute mark.
This is my go to coffee cake recipe and I have included it in my sourdough baking classes because itโs not as much commitment as a loaf. If someone wanted to make this recipe today - and didnโt have an established starter - what can they do as a substitute? Iโve seen some recipes that say add more flour? Would it be the same here?
Hi Zoe, in a discard recipe like this one, if you don't have discard, simply replace it with equal weights of flour and water. For this recipe it would be 62 grams of flour and 62 grams of water or buttermilk.
Can i use this recipe to make coffee cake muffins? What adjustments would you make?
Hi Anita, I would bake them for 10 minutes and then check every 5 minutes until they are done.
Hi, wanting to make for Christmas morning. My daughter is allergic to eggs have you ever tried with flax eggs ?
Thanks
Hi Ellie, Unfortunately, we haven't tested this recipe with flax eggs, so I'm not exactly sure how it would turn out, but I don't see why it wouldn't work. You could also try applesauce to bind it together. If you decide to test it out, please let us know how it turns out!
Hi Ellie! My 1 year old is allergic to eggs as well, and we haven't really started playing around with egg substitutes yet. Did you try it? How did it go? Any other egg substitute recipes you might recommend?
If I bake in a 9 x 9 metal tin what would be the best temperature and time?
Hi Catya, this recipe calls for a 9 x 9 metal pan, so follow the temperature and time laid out in the recipe card.
This coffee cake looks fantastic! I love the photo with the cup of coffee behind the slice of cake. What a beautiful styled photo!
Thank you, Molly!
I made this Coffee Cake and my family and friends loved it! I'll definitely make it again!
