I love to make Marshmallows! Today I made Vanilla Marshmallows with a Peanut Butter Graham Cracker Crust and Chocolate Bars. Which technically makes them Marshmallow S’mores. This is by far my favorite marshmallow recipe for s’mores. And why is that?

Because I used two of my favorite recipes to make this amazing dessert.

How to Make My Favorite Marshmallow Recipe for S’mores

Peanut Butter Graham Cracker Marshmallow S’mores are the best! Especially when the recipe is created from two of my favorites.

One of the tricks to making marshmallows is to line the pan with saran wrap. Then spray it with cooking spray. Marshmallows are very sticky and you want to make sure to follow this step.

Line the Pan with Saran Wrap

After you make the peanut butter graham cracker crust, press it into the pan.

2. Mix the first four ingredients. Press into the baking pan.

3.     Refrigerate twenty minutes.

Vanilla Marshmallows

1.     Place 1/2 cup water in the bowl of a stand-up mixer and sprinkle gelatin on top. Let sit while cooking the sugar mixture.

2.     In a small saucepan combine sugar, light corn syrup, and 1/4 cup water. stir until mixed well. Heat until sugar starts to boil and continue to boil for one minute. Remove from

8. Optional - Place in a warm oven or under the broiler for two minutes until marshmallow and chocolate begin to melt. Serve immediately.

If you are looking for a gelatin substitute, try using agar agar. I haven’t tried it but I have heard it works well.

To use agar, simply dissolve it in hot liquid like water. Let it sit for about 60 minutes until it firms up. You don’t need to store it in the refrigerator.

Generally, agar agar powder can replace gelatin at a 1:1 ratio. In other words, if you need 2 teaspoons of gelatin, use 2 teaspoons of powdered agar agar. If you’re using agar agar flakes, use 1 tablespoon for every 1 teaspoon of agar agar powder.

Serve with chocolate bars.

  1. Wow! These look phenomenal. I will definitely have to try these! I like the idea of serving them with the little fun-sized chocolate bars. A variety of chocolate bars would be fun to try, too, like Krackle and Mr. Goodbar!

  2. Will these keep in the fridge if not serving right away? Or would you recommend cutting first and then storing in fridge (or at room temp)?? Thanks! These look amazing.
