Banana Chocolate Muffin

Overview

There were two remaining bananas, and their skins were a little dark, but muffins were quick to make, so I made them by hand.

Because the bananas are very soft when they are ripe, they can be mashed directly with a spoon. If it's a little hard, wrap a rolling pin in plastic wrap and press it down.
After softening the butter, add sugar and beat until fluffy and light in color.
Add the eggs in two batches and beat until thoroughly mixed before adding the egg liquid.
Completely mixed with eggs.
Add the mashed banana and stir for a while, then add the milk, sift in the flour, baking powder and baking soda and stir. Do not stir in circles to avoid gluten formation.
Add chocolate chips and mix well.
Add the mixed batter into a piping bag, fill the paper cup 80% full, and bake in the middle rack of a preheated 180-degree oven for 20 minutes.
It's baked.
