The combination of peanut butter and oatmeal makes these bars popular. My children love them with a cold glass of milk, and I've taken them to many church suppers, too.

"These PB bars will go quick! Usually make half a recipe using a 11x7 glass pan. easy to assemble. Love the fact that topping goes on warm, no need to wait to frost! But wait until completely cool to cut. Perfect for snow shoveling kids to enjoy! As a volunteer feild editor for Taste of Home magazine I love using a variety of recipes that use classic ingredients."
