I used the same recipe for these as I use for the Chocolate Chip Muffins.
Ingredients:
2 cups all purpose flour
1/3 cup white sugar
1/3  cup brown sugar
2 teaspoons baking powder
1/2 teaspoon of salt
2/3  cup milk (regular or plain almond milk)
1 stick of butter melted and cooled (1/2 cup) (earth balance)
2 eggs  lightly beaten
1 teaspoon vanilla extract
1 cup of cinnamon chips  (more or less to taste)
1 tsp of cinnamon
1/4 tsp of nutmeg
pinch of ground clove & pinch of vanilla bean
Preheat oven to 400 and line muffin tin with muffin cups. In a large  bowl mix together flour, white sugar, brown sugar, baking powder, spices and  salt.
In another bowl stir together eggs, milk, melted butter and  vanilla extract until well blended.  Make a small well in the middle of the dry  ingredients and pour in the wet mixture. Stir until combined and  then add the cinnamon chips
Spoon mixture into the muffin cups.  Bake for 15-20 mins until ligthly brown on top. Allow to cool before  eating or storing.
