I got this from a recent Rachael Ray’s Magazine. Super Yummy, right Kendee?
2 cups all purpose flour
1 ½ teaspoons baking powder
1 teaspoon baking soda
½ teaspoon salt
1 ¼ cups sugar
1 teaspoon cinnamon
1 stick (4 ounces) butter, at room temperature
1 cup sour cream
1 teaspoon pure vanilla extract
1 cup chocolate chips (about 6 ounces)
1--Preheat oven to 350º. Grease an 8-inch square baking pan. In a medium bowl, mix together the flour, baking powder, baking soda, and salt. In a small bowl, combine ¼ cup sugar and the cinnamon.
2--In an electric mixer, beat together the butter and 1 cup sugar until fluffy, about 5 minutes. Beat in the eggs, 1 at a time, then beat in sour cream and vanilla. Fold in flour mixture, in 2 parts, until just combined. Pour half the batter into the cake pan and sprinkle with half the cinnamon-sugar and half the chocolate chips. Spoon the remaining batter as evenly as possible over the filling, spreading gently. Sprinkle with the remaining cinnamon-sugar and chocolate chips.
3--Bake until golden and a toothpick inserted in the center comes out clean, 30-35 minutes.
