Cinnamon Devil'S Food Cupcakes - cooking recipe

Ingredients

2 2/3 cups all-purpose flour
1 1/2 cups cups unsweetened cocoa powder
1 tablespoon cinnamon
2 teaspoons baking powder
1 1/2 teaspoons salt
1 teaspoon baking soda
3 1/2 cups sugar
1 1/4 cups freshly brewed coffee, cooled to room temperature
1 1/4 cups buttermilk
3/4 cup oil
2 large eggs
2 large egg yolks
1 tablespoon vanilla
1 1/2 cups miniature semisweet chocolate chips

Preparation

Set oven to 325 degrees.
Prepare regular muffin tins and line with paper liners.
In a bowl sift together flour, cocoa, cinnamon, baking powder, baking soda and salt.
In a extra large bowl combine sugar, coffee, buttermilk, oil, eggs, egg yolks and vanilla; beat well with an electric mixer until thoroughly combined (about 2-3 minutes).
Add in the dry ingredients; beat on medium speed until blended, scraping bowl occasionally (about 4 minutes).
Stir in the mini chocolate chips.
Spoon the batter evenly between the prepared muffin tins.
Bake for about 20-25 minutes, or until puffed and the center is just firm to the touch.
Transfer the cupcakes to racks and cool completely before frosting.
