Vanilla Muffins with Chocolate Chips

I really love vanilla muffins but since I'm a chocolate lover too , I decided to take make vanilla muffins with added chocolate chips (would've used Mars bars if I had any at home) 

So here it goes ; 

1 cup castor sugar 

1 egg beaten 

2 cups flour 

2 tsp baking powder 

1 cup milk 

1/4 melted butter 

2 1/2 tsp vanilla 

To sprinkle on top of muffins before baking ; 

1 1/2 tsp sugar 

1/8 cinammon 

Bake at 190degrees, for 15-20 mins 

Fill only 2/3 of the containers only 

Do not overbeat :) 

I added chocolate chips but this vanilla muffins recipe is delicious enough to be added with other stuff like Mars bars too :) 

I extracted the recipe from food.com ,

Enjoy !
