S'mores Bars

8 cups Golden Grahams cereal
5 cups mini marshmallows
1 1/2 cups milk chocolate chips
1/4 cup light karo syrup
5 Tbsp butter
1 tsp vanilla
1 cup mini marshmallows

Grease a large bowl and a 9x13 pan. Pour cereal into large bowl. In a saucepan, mix together butter, syrup, 5 cups marshmallows and chocolate chips. Heat over low heat until melted (you may want to melt the butter and syrup together and then add the marshmallows 1 cup at a time. Add the chocolate chips once all the marshmallows are melted). Stir in vanilla. Pour over cereal and quickly toss until cereal is completely coated with marshmallow mixture. Stir in 1 cup marshmallows (I also like to stir in the rest of the bag of chocolate chips at this point). Spread into 9x13 pan and press using back of spoon or moistened hands. Let stand at least 1 hour. Cut into bars.
