FAQ

Can I use frozen rhubarb for this recipe?

Yes, you can use frozen rhubarb in this Lemon Rhubarb Loaf Cake recipe. Just thaw and drain the excess moisture to prevent the batter from becoming too wet. It may also alter the texture slightly but should still be delicious.

How can I tell when the loaf cake is done baking?

To check if the lemon rhubarb loaf cake is done, insert a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready. If it comes out wet with batter, it needs a bit more time.

What can I substitute for buttermilk?

If you don’t have buttermilk on hand, you can make a quick substitute by adding one tablespoon of lemon juice or vinegar to a cup of milk. Let it sit for about 5 minutes before using it in your recipe.

How should I store leftover cake?

Leftover lemon rhubarb loaf cake should be stored in an airtight container at room temperature for up to five days. For longer shelf life, you can refrigerate it, keeping it fresh for an additional few days.

Can I add other fruits to this cake?

Absolutely! Feel free to add other fruits like strawberries or blueberries along with the rhubarb for added flavors. Just be sure to account for their moisture content to avoid altering the loaf’s texture.
