Notes

Don't over-mix them or your muffins will be dense and heavy.
Fill the muffin cups with batter until they are two-thirds full, and bake them until lightly golden brown.
Use room temperature ingredients when making muffins.
Baking times will vary, so check the muffins after 10 minutes and see what they need. 
These delicious blueberry banana muffins can last up to 3 days in an air-tight container. This will help retain their freshness and promote longer storage times.
Alternatively, muffins can be kept in the fridge for up to 5 days or wrapped and frozen for up to 4 weeks.
To reheat any muffins stored in the fridge or freezer, pop them into a preheated oven for a few minutes until warm, and enjoy.
A good way to tell when your muffins are done baking is to check if the top is lightly browned and a toothpick inserted into the center comes out clean.
You should also gently press down on the top of one muffin with your finger; if it springs back up, your muffins are ready to take out of the oven.
