4 Ingredient Peanut Butter Cereal Bars

I. LOVE. CEREAL. In the way that if I buy a box for my apartment, I will finish that box that day no question about it. So in order to curb my cereal craving, but eliminate the urge to just take a full box to the face I made Peanut Butter Cereal Bars. 

They are super simple to make and use only 4 ingredients!  (5 if you include the chocolate drizzle :)) They can be make gluten free based on the cereal you choose and are made with honey instead of a processed sweetener.
