Prepare all the ingredients. Mashed the bananas and set a side. Preheat the oven to 175 Celsius.

Mix dry ingredients: flour, sugar baking soda, baking powder, cinnamon powder and salt. On the other bowl, mix the rest of the ingredients: mashed bananas, melted butter, eggs, milk and half of the chocolate chips.

Transfer the bowl of the bananas mixture into the dry bowl. Mix it well. Place them in the muffin’s cup. Add bits rest of the chocolate chips onto the muffin’s mixtures.

Put the muffin’s mixtures into the oven for about 20minutes. Check for time to time with stick or knife. Since my muffin’s cups are not the same size, after 20 minutes I took out the smaller muffins. I then add another 5 minutes for the other muffins.

Cool the muffins for about 10 minutes, then they are ready.
