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 350°F (175°C) 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.

Followed the recipe ingredients to a "t" and it was delicious. The only thing I did was cooked it for 50 minutes - PERFECT !!!
Meghan says
Had similar issues with bake time and “gummy” texture as some of the other reviews. Overall the cake is delicious! But I did find the recipe a little confusing when explaining which mixture goes where. I think using “filling” and “topping” more consistently in the written instructions would help. It could just be that I was taking too many pauses chasing my toddler to focus though. ☺️

Reduce buttermilk to 1/2cup and baked in springform pan. Cooked all the way through😀
MamaBear says
My first coffee cake ever and everyone I feed it to, liked it! Next time I'm going to added diced apple to the middle cinnamon layer.
Debbie Anderson says
My husband said this was the best coffee cake I have ever made, I have to agree! Normally they come out somewhat dry and I don't care too much for them - but this was different. Very moist! I had fed my sourdough starter the night before and left the discard out on the counter so it was a bit bubbly when I used it, which I think was a good thing! Like others have said it took a bit longer to bake than the recipe called for - also I used a 8.5 x 8.5 metal pan. I put some foil over top and just kept cooking until it was no longer jiggly in the middle, turned out perfect! Will definitely make again!
Shauna says
Absolutely delicious! Thank you so much for sharing!
Msgemh says
Should the sourdough starter discard be recently fed and bubbly?
Amy says
No it doesn't need to be recently fed.
Jessica says
I made this cake this morning but after 45 min in oven it was raw in middle but done on outsides. Any suggestions what I can do next time? I verified I put all of the right ingredients I’m using scale.
Emily says
Fantastic recipe! Tasted delicious and a great way to use up starter. It however took much longer to cook, and once it settled after baking, the middle of the cake was very dense.
Anne O says
Flavor was amazing and complex with the tang of the sourdough balanced by the crunchy sweet topping! My texture was slightly gummy, but I may have under baked it.
