Make sure the butter is not hard from the refrigerator. If it is, let it stand until soft enough to beat with a spoon. Find a small mixing bowl, a wooden spoon, a plate, a fork for mashing the bananas and a knife for spreading.
Measure the butter and honey into a mixing bowl. Using a wooden spoon, beat together until light and creamy.
Peel the bananas and mash on a plate using a fork. Add the banana to the butter and honey and mix well.
Spread the mixture generously on the slices of bread. Cut each slice into quarters and serve.
