Double Chocolate Snack Cake

This is one of my favorite snack cake recipes.  A nice moist cake that doesn't use any eggs.   
1-2/3 cups all purpose flour
1 cup packed light brown sugar
1/4 cup cocoa 
1 teaspoon baking soda
1/4 teaspoon salt
1 cup water
1/3 cup vegetable oil
1 teaspoon vinegar
3/4 teaspoon vanilla extract
1/2 cup semi-sweet chocolate chips

Heat oven to 350 degrees. Spray pam cooking spray into an 8x8x2 inch pan.   
In small mixing bowl combine flour, sugar, cocoa, baking soda and salt.   Add in water, oil, vinegar and vanilla, beat until smooth. Pour into prepared pan.  Sprinkle chocolate chips over the top.
Bake 35 to 40 minutes or until wooden pick inserted comes out clean.
Cool in pan on wire rack .  Cut into squares.   Makes 6 to 8 servings.

This is also good served with cool whip or ice cream.
