Ingredients
List of Essential Ingredients
– 1 cup graham cracker crumbs
– 1/2 cup creamy peanut butter
– 1/2 cup honey or maple syrup
– 1 cup mini marshmallows
– 1/2 cup chocolate chips
– 1/4 cup chopped peanuts (optional)
– 1/4 teaspoon salt
Measurement Details
You need one cup of graham cracker crumbs. This gives the bars their nice base. Use half a cup of creamy peanut butter for a rich flavor. For sweetness, add half a cup of honey or maple syrup. You also want one cup of mini marshmallows that will melt perfectly. Chocolate chips are key, so grab half a cup. If you like crunch, use a quarter cup of chopped peanuts. Lastly, don’t forget a pinch of salt. I recommend using a natural peanut butter that doesn’t have added sugar. For chocolate, semi-sweet or dark chocolate chips work well.
Possible Substitutions
If you want to swap honey, use agave syrup or brown rice syrup. For a gluten-free option, look for gluten-free graham crackers at your local store. You can also use crushed rice cakes instead of graham crackers if you like.

Step-by-Step Instructions
Preparation Steps
1. First, preheat your oven to 350°F (175°C). This step ensures even baking.
2. Next, prepare an 8-inch square baking pan with parchment paper. Leave some paper hanging over the edges. This helps you lift out the bars later.
Mixing the Base
1. In a medium mixing bowl, combine 1 cup of graham cracker crumbs with 1/4 teaspoon of salt.
2. Add 1/2 cup of creamy peanut butter and 1/2 cup of honey or maple syrup.
3. Mix everything together using a spatula. Keep mixing until it becomes smooth and thick like cookie dough.
Assembling the Bars
1. Take about two-thirds of the mixture and press it into the pan. This forms the base layer.
2. Evenly spread 1 cup of mini marshmallows and 1/2 cup of chocolate chips over the base. Make sure they are well spaced.
3. Crumble the remaining one-third of the mixture on top. Gently press it down so it sticks.
Baking and Cooling
1. Place the pan in the oven and bake for 15-18 minutes. Look for golden brown marshmallows.
2. Once baked, take the pan out and let it cool for about 10 minutes.
3. Use the parchment paper to lift the bars out. Then, place them on a wire rack to cool completely before cutting into squares.
Tips & Tricks
Perfecting the Recipe
To ensure even melting of marshmallows, spread them out well. Place them in a single layer on top of the chocolate chips. This way, every bite gets that soft, gooey marshmallow goodness. If you want them extra fluffy, broil them for a minute after baking. Watch them closely so they don’t burn.
When pressing the mixture firmly, use a flat-bottomed glass or your hands. Press down hard enough to create a solid base. This helps the bars hold together. If it’s too loose, they will crumble when cut.
Storage Tips
For best storage, keep the bars in an airtight container. This keeps them fresh and chewy. You can store them at room temperature for about a week. If you want to keep them longer, place them in the fridge. They can last up to two weeks there.
Presentation Tips
Serve the bars on a colorful plate for a fun touch. You can drizzle melted chocolate over the top. This adds a nice visual and taste boost. Garnish with whole roasted peanuts for a rustic finish. It makes them look even more inviting!
Pro Tips
- Use Natural Peanut Butter: Choose a natural peanut butter without added sugars or hydrogenated oils for a healthier option that enhances the flavor.
- Perfectly Golden Marshmallows: Keep an eye on the marshmallows while baking to ensure they turn golden brown without burning, which adds a lovely toasted flavor.
- Chill for Easier Cutting: If you find the bars too soft to cut, refrigerate them for about 30 minutes after cooling to room temperature. This makes slicing much easier.
- Customize with Toppings: Feel free to experiment with toppings like drizzled chocolate, crushed cookies, or even a sprinkle of sea salt for added flavor and decoration.
Variations
Flavor Variations
You can change up the chocolate in your bars. Try using dark chocolate for a richer taste. You can also use milk chocolate for a sweeter treat. If you want something fun, use flavored chocolate chips like mint or caramel. Adding flavored peanut butter opens up even more choices. You might try chocolate peanut butter or honey-roasted peanut butter. These small changes can make your bars exciting.
Dietary Variations
For a vegan option, switch honey for maple syrup. You can also use plant-based butter instead of regular butter. This keeps the bars tasty while sticking to a vegan diet. If you want a low-sugar version, you can use sugar-free chocolate chips. You can also reduce the honey or maple syrup. This way, you can enjoy your treat without added sugars.
Seasonal Variations
Seasonal ingredients can add fun to your bars. In fall, add pumpkin spice to the mixture for a cozy flavor. In winter, try topping the bars with crushed candy canes for a festive touch. You can also decorate the bars with sprinkles for birthdays or other celebrations. These little changes can make your bars fit any occasion.

When you want to enjoy them, take them out and let them thaw at room temperature. This will help them return to that perfect chewy texture.
