Take your bread cubes and place them into a bowl that can be used in the microwave. Then, sprinkle cinnamon and sugar into your bread and mix them together. Cut the banana into slices and combine in the bowl.
Warm the milk for a minute and add to your mixture. Then, mix in egg, vanilla, and yogurt. Combine everything thoroughly and press the mixture down so that the bread moistens.
Microwave the contents of the bowl for 3-4 minutes. You can check halfway through to see if the pudding is done.
This gives you an incredibly delicious banana bread microwave pudding that is so easy to make.
