Oh Henry Bars

adapted from: Lehi City Cookbook

1 c. light brown sugar, packed

1 c. light corn syrup

1 c. peanut butter

1 tsp. vanilla extract

5 1/2 - 6 c. rice krispies

1 bag chocolate chips 

Grease a 9x13-inch baking pan; set aside.  Combine brown sugar and corn syrup in a large saucepan.  It will be very thick at first.  Heat over medium-low heat until sugar is dissolved, stirring frequently; bring to a boil and remove from heat.  Stir in the peanut butter and vanilla until smooth.  Stir in the rice krispies until completely coated.  Press mixture evenly into the prepared baking pan.  Melt chocolate chips in the microwave, stirring every 30 seconds, until melted.  Evenly spread over bars.  Cut while still warm.  Allow to set and serve.  

Jenn's Notes: I used creamy peanut butter and 5 1/2 cups rice krispies so they would be a little extra gooey.
