- Let the loaf cool in the pan for about 20 minutes, then transfer to a wire rack to cool completely before slicing.

Tips & Tricks
- Do not overmix the batter or the loaf may turn dense.
- For a cleaner swirl, drag the knife gently through the batter only a few times.
- If the top starts browning too quickly, loosely cover it with foil during the last 10 to 15 minutes of baking.
- Room-temperature egg and milk help the batter mix more evenly.
- You can add chopped pecans or walnuts for extra texture.
- For a richer flavor, use dark brown sugar in the filling.

FAQ
Can I use active sourdough starter instead of discard?
Yes, you can use active starter, but sourdough discard works especially well here because this loaf relies on baking powder for lift.
Does this bread taste sour?
Not strongly. The sourdough discard adds a mild tang and depth, but the cinnamon and brown sugar are the main flavors.
Can I make this loaf ahead of time?
Yes. Sourdough Discard Cinnamon Bread keeps well for a few days, so it is great for baking ahead.
Can I freeze it?
Yes. Let the bread cool completely, wrap it tightly, and freeze for up to 2 months.
Why is my loaf dense?
A dense loaf usually comes from overmixing the batter or adding too much flour.
Can I add nuts or raisins?
Yes. Chopped nuts or raisins work well in the batter or layered into the cinnamon swirl.
Storage
Store the loaf tightly covered at room temperature for up to 2 days or in the refrigerator for up to 5 days. For longer storage, freeze individual slices or the whole loaf wrapped well. Reheat slices in the microwave for 10 to 15 seconds or warm them in a low oven.

Will you please clarify the brown sugar filling in your recipe separately from the bread part of it? Thanks!
Thanks so much for pointing that out! 😊
I’ve now separated the ingredients to make it clearer:
* The bread batter includes the flour, baking powder, egg, milk, butter, sourdough discard, and vanilla.
* The brown sugar and cinnamon are used as the filling to create the swirl inside the bread.
Appreciate your feedback—it really helps improve the recipe! 💛
