Why You’ll Love This No Bake Treat

  • No-Bake: This recipe is ideal for hot summer days or any time you just don’t want to turn on the oven.
  • 5-Ingredient dessert recipe.
  • Perfect chocolate peanut butter flavor.

I have been reaching for recipes and desserts that take me down memory lane. Easy ideas that bring up all of the feelings of nostalgia. These are the recipes I want to share with my child. I want him to get all of these classics into his memories with mom so he can share them with his kids one day. 

No-bake chocolate Peanut butter bars, lunch lady bars, or school bars… Whatever you call these, they are INCREDIBLE. Minimal ingredients and the taste of Reese’s. All of the magic starts with a no-bake peanut butter crust pressed gently into a pan and then spread with a peanut butter chocolate topping.

Peanut Butter Squares Ingredients

We’ve also heard these referred to as school peanut butter bars!

  • Butter: Butter is what holds the crust together. It is the binding agent that works with the peanut butter to give you a good solid base. It also adds the most incredible buttery flavor that is hard to resist.
  • Peanut Butter: The star ingredient! We have made these about a dozen times. I recommend using creamy, and not crunchy, peanut butter for this recipe. We have also tried it with natural peanut butter. It worked ok, but had a slightly different texture. 
  • Powdered Sugar: Just a tad to sweeten things up. This is also known as confectioners sugar and typically used in frostings. 
  • Graham Crackers: I used grahams, BUT *surprise twist* you can also use Ritz crackers! My husband is a purist and says this craziness, but I love the buttery salt flavor that’s added by the crackers. 
  • Chocolate Chips: Semi sweet is preferred if you would like something close to a Reese’s flavor. 

Semi sweet chocolate chips vs milk chocolate chips

If you ask my Instagram followers, they are firmly divided on which is better. And people will fight to the death to defend their precious chocolate picks. So what is the difference and which one is best for this recipe?

  • Semi Sweet Chocolate Chips– Semi sweet has a high cocoa content which makes it taste closer to a dark chocolate. It is slightly bitter which makes it ideal pairing for desserts that are already plenty sweet (think chocolate chip cookies). 
  • Milk Chocolate Chips– Milk chocolate has a sweeter flavor that is less rich than its counterpart. It tends to be a little more creamy and loved by many.

For me, I prefer semi sweet for all of my recipes. I’m a dark chocolate fan and feel it compliments everything. That being said, milk chocolate pairs wonderfully with bold flavors, like peanut butter. So you cannot go wrong with either variety.

Helpful Tools And Tips

  • Use parchment paper to line your pan to help easily pull the bars out when ready to slice. 
  • Creamy peanut butter tends to work better than crunchy for this recipe. 
  • Use a high powered blender (affiliate) or food processor (affiliate) to get a fine crumb texture. This will give you the best crust. 
  • A handheld mixer (affiliate) will make your crust come together quickly and easily! 
  • Keep your bars stored in an air tight container (affiliate) to help them keep their freshness. 
  • Try substituting Ritz crackers for the grahams in this recipe for an entirely new flavor!

Recipe Notes:

How long do these peanut butter bars need to chill before they’re ready to enjoy?

Patience is key here! Pop them in the fridge for at least 2-3 hours to ensure they set perfectly. Trust me, the wait is worth it.

Can I use natural peanut butter instead of the regular kind?

Totally! Just make sure to give it a good stir before using, as natural peanut butter can separate a bit. This will ensure your bars have that amazing peanut flavor.

Are these bars super sweet?

The sweetness level is just right, thanks to the perfect combo of peanut butter and a touch of sugar. If you prefer things less sweet, you can reduce the powdered sugar a bit and adjust to your taste.

Help! My bars are too crumbly. What went wrong?

Don’t worry, we’ve got you covered. If your mixture seems dry, try adding a bit more peanut butter or a splash of milk until you reach a consistency that holds together when pressed.

Can I freeze these bars for later?

Absolutely! In fact, they make for a fantastic frozen treat. Just slice them up, wrap them individually, and store in the freezer for a quick, cool indulgence.

How long do these bars last?

If you manage to resist eating them all at once, these bars can last in the fridge for up to a week. Just store them in an airtight container to keep them fresh.

  1. Are these the honey grahams? That’s all they see at the store

  2. Maureen Kelly says:

    In the recipe notes you mention honey, but there is no honey in the recipe. Am I missing something?
