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!

  • 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.

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.


  • 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!
