Best ways to enjoy it
This Flourless Oatmeal Banana Cake is delightful on its own, but feel free to get creative! Serve it warm with a dollop of Greek yogurt on the side, or add a drizzle of maple syrup for an extra touch of sweetness. It pairs wonderfully with a cup of coffee or tea and can also be enjoyed as a breakfast option, especially topped with fresh berries or nuts.
Keeping leftovers fresh
Storing your cake properly is essential for maintaining its freshness. To store, cover the cake with plastic wrap or place it in an airtight container. It can be kept at room temperature for up to three days or in the fridge for about a week.
If you want to freeze it, slice the cake and individually wrap the pieces in plastic before placing them in a freezer-safe bag. They can last up to three months in the freezer. Just let them thaw at room temperature when you’re ready to enjoy!
