No Bake Peanut Butter Bars
Just like the lunch lady used to make! These no bake peanut butter bars are thick, creamy, and crave-able! (And super easy!)
School Cafeteria Peanut Butter Bars
School cafeteria food gets a bad rap, but you know that there are some things your lunch ladies made that you probably miss!
Growing up I packed my lunch most days, but there were some days I made sure to buy school lunch. Pepperoni rolls, spaghetti, no bake cookies — just to name a few.
These no bake peanut butter bars are just like the school cafeteria classic. There’s something so satisfying about that rich, peanut butter base topped with chocolate. We used white chocolate for our version, with a touch of dark chocolate too. (You can even try them with chocolate frosting and sea salt like my friend Jennifer makes).
They’re thick, creamy, and crave-able! And so easy to make!

How to Make No Bake Peanut Butter Bars
A free printable copy of this recipe is available at the bottom of the post.
Y’all, these cafeteria peanut butter bars couldn’t be easier to make!
Simply combine all ingredients (except coconut oil and chocolate chips) in a food processor and blend until mostly smooth. Then you press the batter evenly into your prepared 9×9″ baking pan or casserole dish.
TIP: You can also stir by hand, but we like to use a food processor because it is super easy and makes sure that everything is well combined. Our Hamilton Beach “Big Mouth” food processor has lasted us for YEARS…it’s been one of our best kitchen purchases!
The topping is made with melted white chocolate chips mixed with a touch of coconut oil (which helps the chocolate melt smoothly). For looks and an extra chocolate kick, we drizzled melted dark chocolate over top of the white chocolate layer, then used an offset spatula to make a pattern.
TIP: If you want to make your topping even fluffier, try our “Magic” White Chocolate Coconut Oil Frosting!
Now the best part…no baking required! Simply refrigerate for at least two hours to set.
TIP: You can also make this recipe the night before you need it and keep in the fridge.
