Ingredients

  • 1 cup creamy peanut butter
  • 1 cup granulated sugar
  • 1 cup mini marshmallows
  • 1 cup crushed graham crackers
  • 1/2 cup chocolate chips (optional)

Tools Needed

  • Large mixing bowl
  • Spoon or spatula
  • 8×8 inch baking dish
  • Parchment paper (for easy cleanup)
  • Measuring cups

Suggested Substitutions and Additions

  • Use crunchy peanut butter for added texture
  • Substitute agave nectar or honey for granulated sugar for a healthier option
  • Add cocoa powder for a chocolate twist
  • Toss in some nuts or dried fruit for a unique variation
  • Use vegan marshmallows for a dairy-free version

How to Make

Step 1: Mix the Dry Ingredients

Start by gathering all your ingredients and prepping your baking dish. Dust it with a bit of cooking spray or line it with parchment paper for easy removal later. In a large mixing bowl, combine the crushed graham crackers and mini marshmallows. The combination of crunchy and chewy will create a delightful texture.

Step 2: Combine Sugar and Peanut Butter

In another bowl, mix the creamy peanut butter with granulated sugar. You’ll want to stir this until it’s perfectly blended—smooth and creamy like a warm hug. The peanut butter should be thick yet spreadable, and you’ll know it’s right when it smells nutty and inviting!

Step 3: Mix Them Together

Next, gently fold the dry ingredients into the peanut butter mixture. Be sure to mix it thoroughly so that all the graham cracker bits and marshmallows get coated in that luscious peanut butter. The moment they unite, you’ll see that familiar sticky goodness.

Step 4: Press into the Baking Dish

Transfer the mixture into your prepared baking dish. Use a spatula or the back of a spoon to press it down evenly. Make sure it’s packed tightly, as this will help the bars hold together when set.

Step 5: Chill and Set

Pop your baking dish into the refrigerator for about 1-2 hours or until it has fully set. The anticipation will build, but trust me, the wait is totally worth it!

Step 6: Slice and Serve

Once set, remove the bars from the refrigerator and cut them into squares. You can drizzle a little melted chocolate over the top for an extra touch of decadence. Serve them up and watch them disappear!

What to Serve with Peanut Butter Marshmallow Bars (No Bake)

These Peanut Butter Marshmallow Bars pair well with a cup of hot chocolate or even an ice-cold glass of milk. For an elegant touch, consider serving them with fresh strawberries or banana slices on the side. If you’re planning a gathering, check out these related recipes:

Tips for Making It Perfect

  • Prep in advance: You can crush the graham crackers ahead of time to save on prep time.
  • Fix common mistakes: If the bars are too crumbly, try adding a bit more peanut butter to the mix.
  • Make ahead: These bars can be made a few days in advance; just cover them tightly and keep them in the refrigerator.
  • Double the batch: If you’re expecting a crowd, simply double the ingredients and use a larger baking dish!

Storage Instructions

To store these Peanut Butter Marshmallow Bars, place them in an airtight container at room temperature, where they will stay soft, fresh, and flavorful for up to one week. Keeping them tightly sealed helps protect the marshmallow layer from drying out and preserves the rich peanut butter flavor. Stored this way, they’re perfect for enjoying as a quick snack or dessert throughout the week.

If you’d like to extend their shelf life, the bars can also be refrigerated for up to two weeks. Refrigeration helps them stay firmer and can be especially helpful in warmer climates. Be sure they are still stored in an airtight container to maintain their texture and prevent them from absorbing any refrigerator odors.

For even longer storage, freezing is a great option. Wrap each bar individually in plastic wrap to protect them from freezer burn, then place them in a freezer-safe bag or container. They can be frozen for up to three months without sacrificing quality. When you’re ready to enjoy them, allow the bars to thaw in the refrigerator for the best texture, or enjoy them straight from the freezer if you’re craving a refreshing, cold treat.

General Information

The history of no-bake treats like these bars is fascinating. They emerged in kitchens across America during the 1950s, a time when convenience foods became highly popular. Following that era, no-bake recipes gained a loving following due to how easy they could be made, especially for busy families like mine. Whenever I make these bars, I’m reminded of family gatherings and how food has always been a way to connect with those I love.
