Ingredients
- 1 cup sourdough starter (discard or active)
- 1/3 cup vegetable oil
- 1 large egg (room temperature)
- 1 cup all-purpose flour
- 3/4 cup granulated sugar
- 1/2 tsp salt
- 1 tsp baking soda
- 1 tsp ground cinnamon
- 1/2 cup brown sugar (for the swirl)
- 1 tsp ground cinnamon (for the swirl)
- 1/2 cup brown sugar (for topping)
- 2 Tbsp unsalted butter (melted)

Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease a baking pan.

- Step 3: In another bowl, mix the flour, granulated sugar, salt, baking soda, and 1 tsp ground cinnamon.
- Step 4: Gently fold the dry ingredients into the wet ingredients until just combined. Avoid overmixing to keep the cake tender.

- Step 6: Pour the remaining batter over the cinnamon swirl layer.
- Step 7: For the crumb topping, combine 1/2 cup brown sugar, 2 Tbsp melted butter, and 1 Tbsp flour. Crumble this mixture evenly over the top of the batter.

FAQs
Can I use whole wheat flour instead of all-purpose flour?
Yes, you can substitute whole wheat flour for all-purpose flour, but the cake will be denser and have a heartier flavor. Consider using half whole wheat and half all-purpose for a lighter texture.
Do I need to feed my sourdough starter before using it in this recipe?
No, you can use either active or discard sourdough starter for this coffee cake. Using discard is a great way to reduce waste without affecting the flavor much.
