No Bake Chocolate Peanut Butter Bars - are an easy no bake dessert that taste almost like a Reese's! They only need 5 ingredients to make and you probably already have them in your pantry!
Line a 9 inch square baking pan with foil and grease with butter, set aside.
In a large bowl combine all the base ingredients and spread into the bottom of the prepared pan.
In a small microwave safe bowl heat topping ingredients until melted. Stir frequently and don't overheat. Spread over the peanut butter base and refrigerate until cool. (At least 4 hours)
For easier cutting allow bars to sit at room temperature (this way the chocolate topping doesn't crack) Using foil lift the bars out of the pan and with a sharp knife to cut into small squares. Store in the refrigerator.
Notes
These do require chill time to firm up so you will need to plan ahead.
Make ahead: these can be made several days (5-7) in advance and stored tightly covered (after the chocolate has set) in the refrigerator. Or freeze tightly covered for up to 2 months.
Be sure to get the graham crackers to a very fine crumb. Use a food processor for this. I have a mini food processor that works great for these small tasks!
Don't use the natural stir and refrigerate kind of peanut butter for these bars. It is a little too runny and the bars don't hold up quite as well.
For a truer to Reese's flavor use milk chocolate chips. But if you are like me go on the wild side and use semi-sweet or dark or use a combination!
