Chocolate Chip Coffee Cake

per my husband's request- i made coffee cake:

Chocolate Chip Sour Cream Cake (or you can make w/o choc chips)

1 stick butter, at room temperature

1 1/2 cups sugar

3 eggs, separated

1 1/2 teaspoons vanilla extract

16 ounces sour cream

3 cups all-purpose flour

1 teaspoon baking powder

1 1/2 teaspoons baking soda

12 ounces chocolate chips (i used 6 & made half of the coffee cake w/o choc chips)

1/2 cup sugar

1 teaspoon cinnamon

Preheat oven to 350°.

In a large bowl, cream butter and 1 1/2 cups sugar, then mix in the egg yolks and vanilla. Sift flour, baking soda and baking powder together into a separate bowl. Alternately add sour cream and then dry ingredients into butter mixture. Beat eggs whites until stiff, then fold into batter. Mix last 1/2 cup sugar and cinnamon together in a separate, small dish.

In a greased 9″x13″ pan, pour in half of the cake batter. Sprinkle the top with half of the cinnamon-sugar mixture and half of the chocolate chips. Pour remaining batter on top, sprinkling the top with the remaining cinnamon-sugar and chocolate chips.

Bake for 40 to 50 minutes, or until a tester comes out clean.

God Bless!
