Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Lightly grease and flour an 8×8 inch square baking pan or a 9-inch round cake pan.
2. In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, baking soda, ground cinnamon, and salt. Make sure there are no lumps and everything is evenly distributed.
3. In a separate medium bowl, whisk together the melted butter, large egg, vanilla extract, and milk. Ensure the egg is well incorporated and the mixture is smooth.
4. Pour the wet ingredients into the dry ingredients. Stir gently with a spoon or spatula until just combined. Be careful not to overmix; a few small lumps are perfectly fine.
5. Fold in the room temperature sourdough discard. Mix until it’s just incorporated into the batter.
6. Pour the batter evenly into your prepared baking pan. In a small bowl, combine the 2 tablespoons of granulated sugar and 1 teaspoon of ground cinnamon for the topping. Sprinkle this mixture evenly over the top of the cake batter.
7. Place the pan in the preheated oven and bake for 25-30 minutes. The cake is done when a wooden skewer or toothpick inserted into the center comes out clean or with only a few moist crumbs attached. The top should be golden brown and the cinnamon sugar topping will be fragrant.
8. Remove the cake from the oven and let it cool in the pan on a wire rack for at least 15-20 minutes before slicing and serving. This allows the cake to set properly and makes for cleaner slices.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients for this vanilla cinnamon cake is straightforward, focusing on common pantry staples. The star, of course, is your sourdough discard, which should be unfed and at room temperature for the best results. Beyond that, you’ll find that most items are likely already in your kitchen, making this a convenient recipe to whip up on a whim.
INGREDIENTS:

- 1 cup (240g) unfed sourdough discard, at room temperature
- 1 ½ cups (190g) all-purpose flour
- ½ cup (100g) granulated sugar
- ¼ cup (50g) packed light brown sugar
- 1 teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup (113g) unsalted butter, melted
- 1 large egg
- 1 teaspoon vanilla extract
- ½ cup (120ml) milk (any kind)
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
When it comes to substitutions, you have a few flexible options. If you don’t have light brown sugar, you can use all granulated sugar, though the brown sugar adds a nice hint of molasses flavor and moisture. For the milk, any dairy or non-dairy milk (almond, oat, soy) will work perfectly well. If you only have salted butter, simply omit the ¼ teaspoon of added salt from the recipe. Using good quality vanilla extract will really make the flavor pop, so choose your favorite brand.

How To Make It Step By Step With Visual Cues

Making this sourdough discard vanilla cinnamon cake is a simple process. Follow these steps for a perfectly moist and flavorful result.
- Prepare Your Baking Pan and Oven: Preheat your oven to 350°F (175°C). Lightly grease and flour an 8×8 inch square baking pan or a 9-inch round cake pan. This ensures your cake won’t stick and will come out easily.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, baking soda, ground cinnamon, and salt. Make sure there are no lumps and everything is evenly distributed. This step is crucial for even rising and flavor.
- Mix Wet Ingredients: In a separate medium bowl, whisk together the melted butter, large egg, vanilla extract, and milk. Ensure the egg is well incorporated and the mixture is smooth.
- Combine Wet and Dry Mixtures: Pour the wet ingredients into the dry ingredients. Stir gently with a spoon or spatula until just combined. Be careful not to overmix; a few small lumps are perfectly fine and will result in a tender cake. Overmixing can lead to a tough cake.
- Add Sourdough Discard: Fold in the room temperature sourdough discard. Mix until it’s just incorporated into the batter. The discard will add moisture and a subtle tang without requiring any additional leavening time.
- Pour into Pan and Add Topping: Pour the batter evenly into your prepared baking pan. In a small bowl, combine the 2 tablespoons of granulated sugar and 1 teaspoon of ground cinnamon for the topping. Sprinkle this mixture evenly over the top of the cake batter.
- Bake the Cake: Place the pan in the preheated oven and bake for 25-30 minutes. The cake is done when a wooden skewer or toothpick inserted into the center comes out clean or with only a few moist crumbs attached. The top should be golden brown and the cinnamon sugar topping will be fragrant.
- Cool Before Serving: Remove the cake from the oven and let it cool in the pan on a wire rack for at least 15-20 minutes before slicing and serving. This allows the cake to set properly and makes for cleaner slices.
Easy Variations And Serving Ideas That Fit Real Life
This sourdough discard vanilla cinnamon cake is wonderfully versatile, making it easy to adapt for different tastes or occasions. For a simple breakfast, enjoy it as-is with a cup of coffee or tea.
- Fruity Swirl: Before baking, swirl in a few tablespoons of fruit preserves like raspberry or apricot for an extra layer of flavor. Just dollop small spoonfuls over the batter and gently swirl with a knife.
- Nutty Crunch: Add ½ cup of chopped walnuts or pecans to the batter for a delightful textural contrast. This is especially good if you love a bit of crunch in your cake.
- Cream Cheese Glaze: For a more decadent treat, whisk together 4 ounces softened cream cheese, 2 tablespoons softened butter, 1 cup powdered sugar, and 1 teaspoon vanilla extract until smooth. Drizzle this over the cooled cake.
- Apple Cinnamon Twist: Stir in ½ cup of finely diced apple (peeled or unpeeled) along with the sourdough discard for an apple cinnamon cake variation. The apples add moisture and a lovely tartness.
- Serving Suggestions: This cake is fantastic served slightly warm. It pairs beautifully with a dollop of plain Greek yogurt or a scoop of vanilla ice cream if you’re leaning towards dessert. For a brunch spread, cut it into small squares and arrange it on a platter alongside fresh fruit and other breakfast pastries. It’s also excellent packed in lunchboxes for a sweet treat.
Common Slip-Ups And How To Avoid Them
Even with a straightforward recipe like this sourdough discard vanilla cinnamon cake, a few common mistakes can impact the final result. Knowing what to watch out for will help you achieve perfect results every time.
- Overmixing the Batter: This is perhaps the most common baking mistake. When you overmix flour, you develop the gluten too much, leading to a tough, dense cake. Stir the wet and dry ingredients together *just* until combined. A few small lumps are perfectly acceptable and even desirable.
- Using Cold Sourdough Discard: While not as critical as with active sourdough baking, using room temperature discard integrates more smoothly into the batter and contributes to a more even texture. If your discard is straight from the fridge, let it sit on the counter for 30-60 minutes before using.
- Incorrect Pan Size: Using a pan that’s too large will result in a thin, dry cake, while a pan that’s too small might cause the batter to overflow or the cake to be undercooked in the middle. Stick to an 8×8 inch square or 9-inch round pan for the best outcome.
- Opening the Oven Door Too Early: Resist the urge to check on your cake too frequently, especially during the first 20 minutes of baking. Opening the oven door can cause a sudden drop in temperature, leading to the cake sinking in the middle.
- Not Greasing and Flourishing the Pan Properly: A poorly prepared pan can lead to the cake sticking, making it difficult to remove cleanly. Take the time to thoroughly grease with butter or cooking spray and then dust with a light layer of flour, tapping out any excess.
