No bake peanut butter bars ingredients.
  • Salted butter: Your butter will need to be melted. If you use unsalted butter, you will need to add a pinch of salt to the recipe.
  • Graham cracker crumbs: I use Keebler graham cracker crumbs, but you can make your own crumbs with approximately 16 sheets of graham crackers.
  • Light brown sugar: A little brown sugar gives these a deeper flavor.
  • Powdered sugar: Also called confectioners sugar and dissolves easily!
  • Creamy peanut butter: You will need this in both the bars and topping.
  • Vanilla extract: Pure vanilla extract for best taste.
  • Milk chocolate chips: Milk chocolate will most make these bars taste like Reese’s cup candy, although you can use semi-sweet chocolate chips or dark chocolate.

Substitutions and Variations

  • Graham crackers: Try crushed Oreos, Golden Graham cereal, Cheerios, vanilla wafers, or even Teddy Bear grahams.
  • Nut butter: If there is an allergy in the house, use another nut butter like almond butter, cashew or sunbutter.
  • Topping: Add some chopped nuts, crushed pretzels or even crushed Reese’s for the top.
  • Baking chips: Use your favorite! Anything works from butterscotch chips to even a combination of milk and white chocolate chips.

How to Make No Bake Peanut Butter Bars

This is the easiest dessert you will make, even easier than peanut butter balls!

Showing how to make no bake peanut butter bars in a 4 step collage.
  • Gather your ingredients. Keep all your ingredients close by as these chocolate peanut bars are simple to make in only 10 minutes.
  • Peanut butter layer. Mix the butter, graham crackers, sugars, peanut butter and vanilla in a medium bowl until smooth and creamy. If it’s too soft and runny, add in a little more powdered sugar. Then press the mixture into a 9×13″ baking dish and refrigerate.
  • Chocolate layer. Melt the chocolate chips in microwave-safe bowl or over a double broiler on the stove. Stir until smooth, then pour on top of the peanut butter layer. Spread evenly with a spatula.
  • Chill. Place bars back in the fridge until the chocolate has hardened (this usually takes 30 minutes to an hour). You could also place in the freezer for a little to speed up the process. Once hardened, cut into squares.

Expert Tips

  • Mixture too runny: If you’re peanut butter mixture is on the runnier side, try adding in 1/4 cup powdered sugar, mixing well and see if that helps (if not, add a second 1/4 powdered sugar to the mix). Or if your house is warm, refrigerating it should do the trick!
  • Gluten free: For a gluten allergy, try substituting the graham cracker crumbs for crushed gluten free crackers, cookies or cornflakes. I’ve never tried this myself, but a few followers have and said they turned out great.
  • Slicing tip: Use a plastic knife to easily cut the bars. It makes a super smooth cut. I’d wipe the knife clean with a paper towel in between each cut.
  • Cut the recipe in half: Feeding a smaller crowd? Just cut this recipe for no bake peanut butter bars in half and use an 8-inch pan.
  • Line your pan: This will make for easier bar removal! Just line with foil or parchment paper.

FAQs

Can I use natural peanut butter?

No, I don’t think that would work as natural peanut butter you need to stir as the peanut butter and oil separates easily. Use a traditional no stir peanut butter like Jif, Skippy or your favorite.

Will crunchy peanut butter work in these no-bake peanut butter bars?

I think that will work for the bottom layer, although for the top layer a smoother peanut butter may be preferred.

What I can substitute for graham cracker crumbs?

If you don’t have graham crackers on hand or just want to try something different in these no bake chocolate peanut butter bars, try a variety of cereals including cheerios, golden grahams, or even golden Oreo’s. If you are in a different country, digestive biscuits may also work!

Do these taste like a Reese’s peanut butter cup?

I sure do think so and my family backs me up! If you opt to use semi-sweet chocolate chips they will taste less like a Reese’s. So if you want that candy bar taste, opt to use milk chocolate chips for the bars topping.

Storage

  • Store: Store peanut butter chocolate bars in your refrigerator in an airtight container for up to a week. I’ve found that they hold their shape the best when chilled as well as taste the most like a reese’s peanut butter cup!
  • Freeze: After your homemade Reese’s bars are chilled, slice and place them in a freezer safe container or bag for 1-2 months. Thaw and enjoy!
