Indoor S'mores Bars

This recipe was one of my favorites growing up and it was really easy for me to do all by myself when I was younger. It came for the Golden Graham cereal box. I made this last week for my friends and roommates and I think everyone had them cleaned up within a day or two. :) They may look a little messy, but that's just the appearance. They stay together real well and don't melt when you hold on to them -- not that you would be holding them for long amounts of time because they are that good! :)

Indoor S'mores Bars

3/4 cup light corn syrup
3 Tablespoons butter
1 package milk chocolate chips -- the must be milk chocolate, not semi-sweet!
1 teaspoon vanilla
12 oz. box Golden Graham cereal
3 cups mini marshmallows

Grease 9x13 pan. Heat corn syrup, butter and chocolate chips to boiling, stirring constantly. Remove from heat and stir in vanilla. Pour over cereal in a large bowl; toss until completely coated. Fold in marshmallows 1 cup at a time. Press into pan. Let stand 1 hour. Store loosely covered at room temperate. If you seal the pan tightly, the s'mores will get a little soggy.
