Coffee Muffin

Follow the same Procedure from Vanilla Muffin Recipe and add  1 teaspoon Coffee Emulco (This is nothing but Coffee flavored essence).
Or instead of adding Milk to the Muffin mixture, you can add freshly brewed Coffee, it gives you excellent flavor.

Choco chip Muffins

It's all the same procedure, just repeat the process i've stated for Vanilla Muffin.
1/2-1 cup choco-chips
Just add this to the muffin mixture and gently mix and pour in the paper lined Muffin pan cups.
Vanilla Muffin Recipe

Vanilla Muffin

I would say this is the basic batter which could be used to prepare all type of other flavor muffins.

Ingredients
2 cups All purpose flour
1 Egg
1 1/4 cup Milk
1 teaspoon Vanilla extract
1/2 cup Vegetable oil
3 teaspoon Baking powder
3/4 cup sugar
1/4 teaspoon Salt

Method

• Preheat oven to 400 degree f (200 degree C approx)
• In a large bowl mix the flour, baking powder, salt and sugar. Make a well in the center.
• In a separate bowl beat the egg and then add milk, vanilla extract and oil, beat well with the hand mixer.
• Pour the wet mixture into the flour mixture and beat well until moistened, do not over beat. 
• Pour the batter into paper lined Muffin pan cups.
• Bake for 20-25 mins or until it turns golden brown.

Note

• If you have caster sugar, then it becomes more convenient for you, but instead of 3/4 cup just add 1/2 cup of caster sugar.
• If you do not have hand mixer at home, you can just beat with fork.
• If you feel the mixture is very thick by any chance, just add 1/4 cup milk, or if it is too thin you can add 1/4 cup of flour and adjust the sweet level.
