How to keep loaf cake moist
The best way to ensure you don’t end up with a dry loaf cake is to not over mix. If the batter is over mixed you will likely end up with a dense over worked loaf cake. When making, mix the batter just until all the ingredients are combined.

How long are loaf cakes good for?
Loaf cakes will typically last 3-4 days if properly stored. Store the loaf cake in a airtight container to keep it fresh.
Can I freeze this loaf cake?
Yes! If you decide to freeze the loaf cake, cut into individual slices for quicker thawing. Then tightly wrap the loaf cake in plastic wrap and cover with aluminum foil to make sure no air gets in.

Tips for making loaf cake
- Have all of your ingredients at room temperature. This will ensure the batter will come together without the need for overmixing.
- After baking, allow the loaf to cool for at least 10 minutes before taking out of the loaf pan.
- Be sure to tightly wrap the loaf cake to ensure it stays fresh for up to 3 days.
- If you don’t have cooking spray on hand, you can certainly butter and flour the loaf pan. Simply rub butter inside the entire loaf pan, then dust flour inside making sure to coat the entire inside of the pan. Dump out any excess.
