How to Make Sourdough Discard Coffee Cake

Make the Batter—Start by beating the softened butter, sugar, and vanilla extract together in a stand mixer (or with an electric mixer) until light, fluffy, and pale. Scrape down the sides of the bowl as needed. Add the eggs one at a time, mixing well after each addition. Then, add the milk, sourdough discard, and sour cream and mix until just combined. In a separate bowl, whisk together the flour, salt, and baking powder. Fold the dry ingredients into the wet mixture until everything is just combined. If you have time, cover the bowl and refrigerate the batter overnight to let it ferment for extra flavor.

Make the Crumb Topping—In a separate bowl, combine the flour, brown sugar, and cinnamon. Stir them together, then pour in the melted butter and stir until the crumb mixture is lumpy.



Assemble the Cake—Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan, or line it with parchment paper. Spread half of the batter evenly in the prepared pan. Sprinkle half of the crumb topping over the batter, then gently spread the remaining batter on top without disturbing the crumb layer. Finally, sprinkle the rest of the crumb topping on top.

Bake—Place the pan in the preheated oven and bake for 50-60 minutes. To check if it’s done, insert a toothpick into the center of the cake—if it comes out clean, the cake is ready. Let it cool for 15 minutes before slicing and serving.

Baking Tips
- Room Temperature Ingredients: For best results, make sure your butter, eggs, and sour cream are at room temperature before mixing. I know this can be hard to remember sometimes, but it really does make a difference! This helps create a smoother batter and ensures even mixing.
- Don’t Overmix: When adding the dry ingredients to the wet ingredients, mix until just combined to avoid a dense cake.
- Check for Doneness: Oven temperatures can vary, so start checking the cake at the 50-minute mark to avoid over baking.

How to Serve
This coffee cake is perfect for a cozy breakfast, an afternoon snack, or even as a sweet treat for brunch. Serve it with a hot cup of coffee or tea for the ultimate indulgence. It’s great on its own, but you can also pair it with a dollop of whipped cream or a scoop of vanilla ice cream for a fun treat or to dress it up and make it a dessert, which we all love!
How to Store and Reheat
Storing this recipe is quite simple. Just keep any leftover coffee cake in an airtight container at room temperature for up to 3 days. If you want to keep it fresh for longer, store it in the fridge for up to a week.
Reheating is a must if you have any leftovers that is. We tend to devour it all in one sitting! But I do love to reheat it for a little treat! To reheat, simply pop a slice in the microwave for 15-20 seconds or warm it in the oven at 350°F for 10 minutes.

Recipe FAQs
Yes, you can use active sourdough starter, but be sure to reduce the amount of flour and liquid in the recipe to compensate for the starter’s moisture content.
Yes, you can freeze this coffee cake! Wrap it tightly in plastic wrap and foil, and it will last for up to 3 months. To reheat, let it thaw overnight and warm it in the oven.
If you don’t have sour cream, you can substitute it with plain yogurt or buttermilk.
