Reese’s No Bake Peanut Butter Bars

These easy-to-make, no-bake Reese’s bars are some of my favorite desserts.

They come together quickly with no cooking, five ingredients, and little fuss. And they’re impossible to resist.

After all, who can turn down the classic combination of peanut butter and chocolate?

Homemade Reese’s Bars 

These babies have all the rich, indulgent flavor of Reese’s Cups but at a fraction of the cost.

Better yet, with just a handful of ingredients, you can make a whole pan!

Homemade Reese’s bars are a treat anyone can appreciate, especially lazy chefs like me. 

Every bite offers nutty, creamy, and chocolatey goodness.

Made in minutes with pantry staples, these no-bake peanut butter bars are a delightful treat, no matter the season.

And they’re such a crowd-pleaser, I never have leftovers!

Ingredients 

These no-bake peanut butter bars require only five ingredients!

• Graham cracker crumbs – I typically use Honey Maid graham crackers. I place them in a sealed Ziploc bag and crush them with a rolling pin. This gets them nice, small, and powdery. 

• Confectioners’ sugar – Unfortunately, granulated sugar won’t work for this recipe. You need soft, fluffy confectioners’ sugar to help hold everything together. 

• Peanut butter – I’ve known people to use crunchy peanut butter in this recipe, but I don’t recommend it. Creamy peanut butter is easier to work with and gives you a more authentic Reese’s texture.

• Butter – Melt the butter before adding it to the recipe. I like salted butter for the contrast, but you can use unsalted. 

• Milk chocolate chips – Use a high-quality brand. Alternatively, you could chop and melt your favorite milk chocolate candy bar. 

I sometimes add a dash of coarse sea salt on top for aesthetics. Plus, the salt contrasts nicely with the bars’ sweetness. 

How to Make Reese’s Bars 

Here’s an overview of the steps for making these copycat Reese’s bars: 

1. Make the peanut butter layer. Start by combining the graham cracker crumbs, sugar, and peanut butter. Mix well, then add the melted butter. Stir until you have a smooth, uniform mixture. 

Pour the mixture into a 9 x 13-inch pan. Then, spread and press it evenly into the dish. 

2.  Make the chocolate layer. Microwave the chocolate chips until melted. 

Then, pour the melted chocolate over the peanut butter layer in the dish. Use a spatula to help you spread the chocolate evenly over the peanut butter. 

3. Chill. Chill the uncut bars in the fridge until they’re just set. Don’t let them stay in the fridge too long, or they’ll get too hard and be impossible to cut. 

4. Slice and serve. Once the mixture is just set, remove it from the fridge and cut it into squares. Serve, and enjoy! 

Tips and Tricks 

Remember these tips and tricks while making your Reese’s bars: 

• Ditch the natural peanut butter. In most things, natural is better, but that’s not true for these bars. Natural peanut butter is too greasy and will completely alter the bars’ texture. 

• Use parchment paper. You don’t want to spray the baking dish, which can alter the bars’ taste and texture. However, you can use parchment paper to make removal and cleanup easier. 

• Crush things up! Your graham crackers, that is. I like to place them in a sealed plastic bag and crush them with a rolling pin. Others prefer pouring them into a food processor and crushing them that way. Do whatever is best for you. 

• Go for a plastic knife. I don’t know why, but plastic knives cut through these bars better than steel. Sometimes, the steel sticks to the chocolate and causes the bars to crack. Plastic knives don’t stick as badly. 

• Give them chill time. The only chill time in the recipe is after you’ve fully assembled the bars. However, you can also chill after adding the peanut butter mixture to the pan. (But BEFORE adding the chocolate.) It’ll make the peanut butter layer more stable and less likely to melt under the warm chocolate. 

Variations 

There are also a few variations you can try:

• Vary the peanut butter. While I don’t recommend using crunchy peanut butter, others enjoy making that swap. You can also leave out the peanut butter entirely. Try almond or cashew butter instead. 

• Switch up the chocolate chips. Similarly, you can vary the chocolate chips. Use semi-sweet for bars that are a little less sweet. Or use dark chocolate for a richer, more bittersweet flavor. I’ve never tried making the bars with white chocolate, but I imagine that would work, too. 

• Swap out the graham crackers. Yep! You can even swap out the graham crackers for something else. Try Teddy Grahams or Nilla Wafers. For extra chocolate, use crushed Oreos. 

• Add sea salt. As mentioned, I sometimes add sea salt to the tops of my Reese’s bars. It makes them look nicer and gives them a delightful sweet-n-salty taste. 

• Make them gluten- or dairy-free. For gluten-free bars, simply use gluten-free graham crackers. For dairy-free, use dairy-free chocolate chips and vegan butter. 

• Top them off. Sea salt isn’t the only topping you can try. Experiment with crushed pretzels or chips, extra chocolate chips, toffee bits, and more! 

How to Store & Freeze 

Because they’re best when cold, storing leftover Reese’s bars is simple.

To Store: Place the bars in an air-tight container and store them in the fridge for up to a week. 

To Freeze: Freeze the bars in a freezer-safe bag or container for up to 2 months. Eat them frozen or let them thaw in the fridge overnight. 

If you forget to get them out of the freezer, you can just set them on the counter for about 20 minutes to soften.

It’s okay if they aren’t fully thawed, as they taste great frozen, too. You just need them soft enough to eat them!
