Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Lightly grease and flour an 8×8 inch square baking pan, or line it with parchment paper, leaving an overhang on two sides for easy removal.
2. In a large bowl, whisk together the 1 1/2 cups all-purpose flour, 1/2 cup granulated sugar, 1 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/4 teaspoon salt. Make sure there are no lumps and everything is well combined.
3. In a separate medium bowl, whisk together the 1/2 cup melted unsalted butter, 1/2 cup sourdough discard, 1/2 cup milk, 1 large egg, and 1 teaspoon vanilla extract until smooth and fully incorporated.
4. Pour the wet ingredient mixture into the dry ingredient mixture. Stir gently with a spatula or wooden spoon until just combined. Be careful not to overmix; a few small lumps are fine. Overmixing can lead to a tough cake.
5. In a small bowl, combine the 1/2 cup all-purpose flour, 1/4 cup granulated sugar, 1/4 cup packed light brown sugar, and 1/4 teaspoon ground cinnamon. Add the 1/4 cup cold, cubed unsalted butter. Using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
6. Pour the cake batter into your prepared baking pan and spread it evenly. Sprinkle the crumb topping generously over the batter. Place the pan in the preheated oven and bake for 30-35 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The topping should be golden brown.
7. Remove the coffee cake from the oven and let it cool in the pan on a wire rack for at least 10-15 minutes. While it cools, prepare the glaze by whisking together the 1/2 cup powdered sugar, 1-2 tablespoons milk or water, and 1/4 teaspoon vanilla extract until smooth. Drizzle the glaze over the slightly warm or fully cooled cake before slicing and serving.

Gathering your ingredients for this coffee cake is straightforward, focusing on common pantry staples. The beauty of this recipe lies in its simplicity and the way everyday items come together to create something truly special. There’s no need for exotic flours or hard-to-find ingredients, making it accessible for any home baker.
INGREDIENTS:

- 1 ½ cups all-purpose flour
- ½ cup granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup (1 stick) unsalted butter, melted
- ½ cup sourdough discard (unfed, at room temperature)
- ½ cup milk (whole or 2%)
- 1 large egg
- 1 teaspoon vanilla extract
- ½ cup all-purpose flour
- ¼ cup granulated sugar
- ¼ cup packed light brown sugar
- ¼ teaspoon ground cinnamon
- ¼ cup (½ stick) unsalted butter, cold and cut into small pieces
- ½ cup powdered sugar
- 1-2 tablespoons milk or water
- ¼ teaspoon vanilla extract
When it comes to ingredients, feel free to use your preferred brands for flour, sugar, and butter. For the milk, whole milk will give you a richer cake, but 2% milk works perfectly fine. If you don’t have unsalted butter, you can use salted butter and reduce the added salt in the recipe by half. The sourdough discard should be unfed and at room temperature for the best results, as this ensures it blends smoothly into the batter and contributes its characteristic flavor without active leavening.

- Mix the Dry Ingredients for the Cake: In a large bowl, whisk together the 1 ½ cups all-purpose flour, ½ cup granulated sugar, 1 teaspoon baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt. Make sure there are no lumps and everything is well combined.

- Combine Wet and Dry for the Cake Batter: Pour the wet ingredient mixture into the dry ingredient mixture. Stir gently with a spatula or wooden spoon until just combined. Be careful not to overmix; a few small lumps are fine. Overmixing can lead to a tough cake.
- Prepare the Crumb Topping: In a small bowl, combine the ½ cup all-purpose flour, ¼ cup granulated sugar, ¼ cup packed light brown sugar, and ¼ teaspoon ground cinnamon. Add the ¼ cup cold, cubed unsalted butter. Using your fingertips or a pastry blender, cut the butter into the dry ingredients until the mixture resembles coarse crumbs.

Easy Variations And Serving Ideas That Fit Real Life
This Sourdough Discard Coffee Cake is wonderfully versatile, allowing for simple tweaks to suit different tastes or occasions. For a touch of fruitiness, consider folding ½ cup of fresh or frozen berries (like blueberries or raspberries) into the cake batter before pouring it into the pan. If using frozen berries, don’t thaw them first to prevent them from bleeding color into the batter. For a nutty crunch, you can add ½ cup of chopped pecans or walnuts to the crumb topping mixture.
When serving, this coffee cake is perfect on its own, but it also pairs beautifully with a dollop of whipped cream or a scoop of vanilla ice cream for a more decadent dessert. It’s an excellent addition to a brunch spread, alongside fresh fruit, yogurt, and other breakfast items. For a quick snack, a slice of this cake with a warm mug of coffee or tea is pure comfort. Kids often love it as an after-school treat, especially if you add chocolate chips to the batter!
Common Slip-Ups And How To Avoid Them
Even simple recipes can have common pitfalls. Being aware of these can help ensure your Sourdough Discard Coffee Cake turns out perfectly every time.
- Overmixing the Batter: This is perhaps the most common mistake in baking. Overmixing develops the gluten in the flour too much, leading to a tough, dense cake. To avoid this, mix the wet and dry ingredients only until just combined. A few small lumps are perfectly acceptable.
- Discard Temperature: While the recipe specifies room temperature discard, using cold discard straight from the fridge can affect the batter’s consistency and potentially the baking time. Allow your discard to come to room temperature for about 30 minutes to an hour before use.
- Incorrect Pan Size: Using a pan that’s too large will result in a thinner, drier cake, while a pan that’s too small might cause the batter to overflow or bake unevenly. Stick to the recommended 8×8 inch square pan for the best results.
- Underbaking or Overbaking: An underbaked cake will be gummy in the center, while an overbaked cake will be dry. Always rely on the toothpick test: insert a wooden skewer into the center of the cake; it should come out clean when done.
- Skipping the Crumb Topping: While technically optional, the crumb topping is essential for the classic coffee cake experience. Don’t skimp on it, as it adds delightful texture and flavor. Ensure the butter for the topping is cold for the best crumbly consistency.
How To Store It And Make It Ahead Without Ruining Texture
Proper storage is key to keeping your Sourdough Discard Coffee Cake fresh and delicious. Once completely cooled, store the coffee cake in an airtight container at room temperature for up to 3-4 days. If you’ve added a glaze, make sure it’s fully set before covering to prevent sticking. For longer storage, you can freeze individual slices or the whole cake (unglazed) for up to 2-3 months. Wrap slices tightly in plastic wrap, then place
