Oatmeal Chocolate Bars

I've seen so many recipes for chocolate oatmeal bars recently and adapted a recipe from Eat Better America. Unfortunately I burned the bottom of these bars. The top tasted good, though! The chocolate mixture for the swirl was excellent, and I hope to find more uses for it.

Ingredients

1/2 cup semisweet chocolate chips 

1/3 cup sweetened condensed milk
1 cup wheat flour
1/2 cup old-fashioned
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
3/4 cup packed brown sugar
1/4 cup canola oil
1 teaspoon vanilla
1 egg

Instructions

Heat chocolate chips and milk over low heat, stirring frequently, until chocolate is melted and mixture is smooth; set aside.
Heat oven to 350°F. Spray 8-inch or 9-inch square pan with cooking spray.In a large bowl, mix flour, 1/2 cup oats, the baking powder, baking soda and salt; set aside. In a separate bowl, stir brown sugar, oil, vanilla, and egg until smooth; stir into flour mixture until blended.
Pour dough into pan. Drop spoonfuls of the chocolate mixture on top and swirl with a knife.

Bake 20-25 minutes. Cool completely.

Yields 16 bars.
