How to Make Oatmeal Crisp Marshmallow Squares

Preheat oven to 350°F (175°C). Grease a 9x13 inch baking pan.
In a large saucepan, melt butter over medium heat. Stir in marshmallows and vanilla extract until completely melted and smooth.
Remove from heat and stir in rolled oats and Rice Krispies cereal until evenly coated.
Pour mixture into the prepared baking pan and press firmly into an even layer.
Bake for 10-12 minutes, or until lightly golden brown.
Remove from oven and let cool completely. Once cool, melt chocolate chips (you can do this in the microwave or double boiler) and spread evenly over the top.
Refrigerate for at least 30 minutes to allow the chocolate to set completely before cutting into squares.
