Nothing is easier than a sourdough lemon pound cake. Add optional glaze for a sweet and tangy dessert option you can store in the freezer.

Pound cake is a super simple dessert to make - just about as easy as a quick bread! Nothing finicky here, just tangy and sweet lemon! We added sourdough starter to give a quick boost for our tummies. Our family does really well even on store bought flour when we ferment it just a bit.
Use up your bananas, too, and make Sourdough Banana Bread. Have a quick grab and go option when you stash Applesauce Muffins in the freezer. When you have a bit more time for proofing your dough, Cinnamon Raisin Bread is the perfect slice with your mug of tea.
Key Ingredients
Flour - I like organic unbleached flour. It's a great option for when I'm not in the mood to grind my own.
Lemons - Always use fresh lemons, not the bottle. We need the zest anyway!
Sugar - A combo of maple syrup and brown sugar gives us a great flavour.
Sour Cream - A great way to achieve a tender crumb in your cakes is to add sour cream. You can also use yogurt, but I recommend regular and not Greek for the added moisture.
Sourdough - You can use active or discard, either is fine. We aren't counting on it for leavening but if you want the dough to really ferment overnight, go with active starter.

Step 5: Ferment if desired, then pour into greased pan.
Step 6: After baking, allow to cool completely before icing.
FAQs
One average lemon can yield 2-3 Tablespoons of lemon juice. You might need anywhere from 5-8 lemons here, depending on size and what juice they give. Store them at room temperature and gently roll them around on the counter under your hand before juicing. Also, always zest first from the whole fruit to make it easy on yourself, then juice them. You can top off with bottled juice if necessary, but I always say using fresh is best!
This sturdy cake will last on the counter about a week or so. If you want to store for longer, I recommend freezing it. Allow to cool completely and don't add any sort of icing or glaze. Then wrap well before popping in a bag for storage. Thaw overnight before glazing, slicing, and serving.

Delicious!! I followed the recipe exactly as written with the exception of only using 1/4 cup of maple syrup as that is what I had. I used plain yogurt. I did not ferment the batter. It looked like a lot of batter but fit perfectly in my 9x5 loaf pan. Started testing for doneness after 50 minutes, ended up baking for a total of 65 minutes. The crunchy crust is wonderful and the bread is nice and moist with the perfect punch of lemon. With the icing on top we did not miss the other 1/4 cup of maple syrup. This will be a go-to recipe from now on!
