• Place the flour in a large bowl.
• Add baking powder to the flour and mix well to combine evenly with the flour.
• Also add sugar to the flour and stir well to mix evenly.
• In a different bowl, beat the eggs very well.
• Also add milk, vanilla extract and oil, mix well to combine with the beaten eggs.
• Add the prepared egg milk oil mixture to the dry flour mixture, stir well to combine to form the muffin batter. Make sure there is no dry flour left at the bottom of the bowl.
• Add the frozen blueberries (you may use fresh blueberries as well) and semi sweet chocolate chips to the bowl and gently mix in to spread them evenly with the batter.
• Now the batter for making blueberry chocolate chips muffins is ready!

To make blueberry chocolate chip muffins

• Preheat oven to 400 degree Fahrenheit.
• Prepare a standard size muffin pan by greasing with little oil or use liners. If you use a good quality non stick muffin pan or silicone muffin pan, this is not necessary as the muffins usually do not stick on them and will come out easily.
• Once the muffin pan is ready, pour the batter evenly into all the 12 muffin moulds (the batter is just enough to make 12 standard size muffins so dividing the batter is easy).
• If you are using silicone muffin pan, it is a good idea to place the muffin pan in a large cookie sheet or baking tray so you can handle it easily.
• Place the muffin pan in the preheated oven and bake for about 22 to 25 minutes until the muffins are cooked through and they look light golden brown in color.
• You can insert a toothpick through the center of the muffins to see if it's cooked completely since there won't be any batter sticking in the toothpick once the muffins are cooked. Since these are blueberry chocolate chip muffins, there could be some residue from the blueberries or chocolate chips which is fine.
• Once the muffins are baked, immediately transfer them from the hot oven to avoid further baking.
• Allow the muffins to completely cool down before you try to take them out of the moulds, to avoid the muffins sticking to the pan.
• Once the muffins are cooled, you can easily pull them out of the pan if you are using silicone muffin pan or non stick pans (or you need to use liners).
• Enjoy the muffins for a delicious evening snack or after school snack or you may save them for next day breakfast as you like!
