Kitchen Tools You’ll Need
- Mixing bowl
- Whisk
- Measuring cups and spoons
- Baking dish (9×13 inch)
- Rubber spatula
Ingredients
- ½ cup butter, softened (adds richness)
- 1½ cup white sugar (provides sweetness)
- 2 teaspoons vanilla extract (enhances flavor)
- 2 eggs (binds ingredients)
- 1 cup whole milk (adds moisture)
- 1 cup sourdough discard or active starter (adds flavor and texture)
- 4 teaspoons baking powder (helps cake rise)
- 3 cups all purpose flour (forms structure)

- 5 Tablespoons flour (for cinnamon topping)
- 4 teaspoons ground cinnamon (adds warm spice)
- 6 Tablespoons butter, melted (for topping moisture)
How to Make Quick Sourdough Discard Coffee Cake
Step 1. Begin by preheating your oven to a temperature suitable for baking. While it heats up, prepare your baking dish by greasing it lightly to ensure easy removal of the cake once it’s done.
Step 2. In a mixing bowl, cream together the softened butter and white sugar until the mixture is light and fluffy. This will create a nice texture and aeration in the batter, setting a solid base for the cake.
Step 3. Add the vanilla extract and eggs to the butter-sugar mixture. Mix until everything is well combined. The batter should appear smooth, indicating that the eggs are fully incorporated.
Step 4. Gradually mix in the whole milk and sourdough discard. Combine gently, ensuring that the dough doesn’t become overworked. The mixture should be moist but still have a slight thickness.
Step 5. In another bowl, combine the baking powder with the all-purpose flour. Slowly add this dry mixture into the wet ingredients, mixing just until you see no dry flour. This assures the cake has the right consistency without becoming tough.
Step 6. In a separate bowl, prepare the topping by mixing the brown sugar, flour, and ground cinnamon. This will create a deliciously sweet and spiced layer on top of the cake.
Step 7. Pour half of the cake batter into the prepared baking dish, smoothing it out evenly. The first layer will act as a base for the topping you’ll add shortly.
Step 8. Sprinkle the cinnamon mixture over the first layer of batter, ensuring an even coverage. This step adds a lovely contrast of flavor and texture that pairs well with the sweet batter.
Step 9. Carefully add the remaining cake batter on top of the cinnamon layer. You can smooth this out lightly with a spatula. This forms the final layer of your coffee cake, ready for baking.
Step 10. Drizzle the melted butter over the top of the batter. This will create a lovely crust as the cake bakes, enriching the flavor and browning the topping nicely.
Step 11. Place the baking dish in the preheated oven. Bake until the cake is golden brown and a toothpick inserted into the center comes out clean. This indicates that your cake is perfectly baked.
Step 12. Once done, allow the cake to cool slightly in the pan before serving. This will make it easier to cut into squares while still warm, inviting everyone to enjoy a slice.

Pro Tips for Best Results
- Ensure your butter is at room temperature for easy creaming, which will help achieve a fluffy cake.
- Use fresh baking powder for best results; this is crucial for the rise and texture of the cake.
- Avoid overmixing the batter once the flour is added to keep the cake tender.
- When measuring flour, spoon it into the cup and level it off; this prevents dense, dry cake.
- Let the cake cool slightly before cutting to maintain its structure and prevent crumbling.
Common Mistakes to Avoid
- Using cold butter: Cold butter doesn’t cream well with sugar, leading to a denser cake. Always use softened butter for optimal texture.
- Overmixing the batter: This can result in a tough cake. Once combined, mix gently and stop when there are no dry streaks.
- Incorrect oven temperature: If your oven is too hot, the cake may brown too quickly on the outside while remaining raw inside. A properly preheated oven is essential.
- Not measuring ingredients accurately: Inaccurate measurements can affect the cake’s texture and flavor. Use measuring cups and spoons for precision.
- Skipping the cooling step: Cutting the cake while it’s still hot can lead to crumbling. Allow it to cool slightly in the pan before slicing.
- Using old sourdough discard: If your discard isn’t fresh, it can affect the flavor of the cake. Always use recent discard for the best taste.
Variations & Substitutions
You can add a handful of nuts or chocolate chips to the batter for extra flavor. Alternatively, consider adding a layer of fruit, such as sliced apples or berries, for a fruity twist. If you prefer a less sweet cake, reduce the sugar in the batter slightly while still enjoying that cinnamon topping for balance.
Storage & Reheating
Store any leftover coffee cake at room temperature, covered, for up to three days. If you want to keep it longer, refrigerate, ensuring it’s in an airtight container to maintain moisture. If freezing, wrap slices individually and store them in a freezer-safe bag for up to three months. When ready to enjoy, thaw at room temperature or reheat in a microwave for a few seconds, being careful not to dry it out.
