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.

This was delicious! I made it to give to my daughters preschool teachers as a thank you before the holidays treat and everyone said it was great!
Amy says
Thank you Erin! 🙂
KayDee says
This is sooooooo good! Highly recommend. I just took out my old favorite coffee cake out of my recipe boo and replaced it with this! YUM.
Amy says
Thank you KayDee! 🙂
Colette says
Easy to put together. Happy to have a good recipe to use my discard in, I usually make pizza dough! I used almond essence instead of vanilla and it’s delicious, I also ran out of butter so used coconut oil in the actual cake but butter in the topping. I also had to bake mine for 15 minutes longer than the recipe said to.
Billie Jo Tumlinson says
This looks great, and I can't wait to try it. I'm curious if you've (or anyone has) tried letting the batter ferment overnight in the fridge before baking it. I'm wanting to use my discard to its full advantage, but I'm still a newbie. Thanks@
Elise says
Hello there, I made the cake twice now, the flavor is amazing, but the cake is coming very dense and not fluffy at all. Do you know what I have done wrong? It could be I use the discard when was active and bubbly?
Amy says
Hi Elise, this is meant to be more of a dense type of cake than a traditional cake that gets frosted. I don't think you've done anything wrong!
Whitney Andrews says
Can I make this with unfed discard from the fridge or does it need to be recently fed discard?
Amy says
Yes you can make it with unfed discard from the fridge.

Jonathan says
This sourdough coffee cake is great. I only had a 9 x 13 pan into a followed direction by one of the commenters to multiply the recipe by 1.5 and it turned out great. I also added blueberries and use another recommendation by one of the commenters to add oats to the crumble topping. This recipe was a big hit

Wonderful! So glad you enjoyed it, Jonathan. Thank you for your feedback.
