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:

  1. Pour half of the cake batter into the greased baking dish and sprinkle the cinnamon sugar mixture evenly across the surface of the batter.
  2. Carefully pour the remaining batter over the cinnamon sugar mixture. Use an offset spatula to gently spread the batter evenly. 
  3. Break up the crumble topping with your fingers and sprinkle evenly over the top.
  4. Bake for 40-45 minutes or until a toothpick inserted in the middle comes out clean.

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.

      I doubled it with a 9 x 13 and it literally took 75 minutes to bake. I felt like this was just ok - the topping was not as crispy as I would like. I donโ€™t think I will make again or at least try a 10x14 pan.

    THANK YOU FOR THIS RECIPE! Could be the best coffee cake Iโ€™ve ever had. That being said, I did modify it - way too much sugar and white flour for me to enjoy the decadence. In the cake I used a combo of almond flour, ground oats and whole wheat instead of white, half the butter, yogurt for sour cream and skipped that brown sugar (added some spiced maple syrup). Kept the rest but did go even heavier on pecans (toasted) My only problem now is deciding if I Like it better cold or toasted โ€ฆ

    Best coffee cake I've ever had! The recipe is simple enough where little kids can help mix and sprinkle the layers. Used a 9x9 as the recipe advised. Came out perfectly. I did need to bake it an extra 10 minutes or so to set the center. Thank you for this wonderful recipe!

  3. 5 stars
    This recipe was perfect! Baked up beautifully. I let the batter ferment overnight in the fridge & baked in the morning. Thank you!

    Just made the coffee cake. It's a winner! We cut into it before it was cooled. I think we'll have to heat it before we eat it from now on! I didn't have buttermilk, so I used whole milk and added lemon juice. It was perfect! Is there a way of making this lower in sugar for a diabetic to enjoy? Love your site, so happy I've found it!.

    I made this recipe vegan and it was amazing! Substituted flax eggs for eggs, cashew milk yogurt for sour cream, almond milk with lemon juice for the buttermilk, and used plant butter. Highly recommend. So moist and delicious.

  7. Made this and it was amazing! My only issue was my center cinnamon layer fell to the bottom in some places. Does anyone know how to prevent this?

  8. I'M TOO EXCITED TO TRY! CAN THE BUTTERMILK BE REPLACED WITH ANYTHING ELSE? CAN I LET THIS FERMENT EITHER OVERNIGHT OR FOR THE DAY? THANKS:)

    1. Yes you can replace the buttermilk with any type of milk you like, dairy or non-dairy. You can let the batter ferment overnight or during the day at room temperature or in the fridge for longer.
