Remove the amount of frozen bananas or banana chunks you need from the freezer.
Place the bananas into a container with fairly high edges, like a bowl, rather than a flat plate, to catch the liquid that they leak as they thaw. This liquid can be used in the recipe.
Leave the frozen bananas out at room temperature until they thaw completely.
Add the bananas to the recipe along with any of the fruit's liquid.
