I love anything caramel, peanut butter, or chocolate. So hand me something that incorporates all three into one and I’ll definitely be a happy camper. These yummy bars are like eating a candy bar. Except better, because they are made with all fresh ingredients from your very own kitchen. They are sooo good!

I recommend using semi sweet chocolate chips in this recipe. They help balance out that ooey gooey caramel layer that forms as the sweetened condensed milk bakes. And the oats add a nice hearty crunch.
