Why You'll Love These Chocolate Peanut Butter Marshmallow Squares

• 3 Ingredients!!! These marshmallow squares only require marshmallows, chocolate chips, and peanut butter.
• They are quick and easy! They do require some time to chill before they are ready to eat, but the actual time is takes to prepare the ingredients and make them is under 10 minutes.
• You don't need fancy equipment to make them. You only need one bowl, a rubber spatula, and an 8x8 square pan to make these chocolate peanut butter marshmallow squares

Ingredients You Need

You will see all of the ingredients and instructions in the recipe card below. Here are main ingredients with some substitutions recommendations.

• Semi-sweet chocolate chips. I definitely don't recommend using milk chocolate chip unless you like extra sweet! We gain sweetness from the marshmallows and peanut butter.
• Smooth Peanut Butter. I like the texture of this bar with smooth peanut butter because it helps make an ultra soft bar. If you wanted to add some crunch, go ahead and use crunchy peanut butter.
• Mini Marshmallows. I don't recommend using regular size marshmallows, they're just too big and won't allow the chocolate peanut butter mixture in between them enough. The marshmallows add texture and a soft pillowy square.

How to Make Chocolate Peanut Butter Marshmallow Squares

Full instructions are found in the recipe card below. Here are the main steps.

Measure out your peanut butter, marshmallows, and chocolate chips. Line an 8x8 square pan with parchment paper.

Create a double boiler on the stove top. To do this, place several inches of water in a medium saucepan and place a medium glass or metal bowl on top of the pot. Turn to low to medium heat and add chocolate chips and peanut butter to the bowl.

Stir continuously over low to medium heat. It's important to not overheat the chocolate or can lock up and lose it's smooth texture, become clumpy and difficult to work with.

Stir mixture continuously until chocolate chips and peanut butter melt. I like to take the bowl off when there are a couple of full chocolate chips left and stir over no heat to get those remaining chips melted. This helps prevent the mixture from locking up.

Next, remove the bowl from heat and pour in the marshmallows. Fold the marshmallows into chocolate peanut mixture until they are completely covered.

Pour into an 8x8 pan lined with parchment paper. Sprinkle extra marshmallows on top and refrigerate for about 1 hour or until set.

Slice and serve or for an extra fun treat (especially for kids) use a cookie cutter to cut these into your favorite shapes. I like to make these for Valentine's Day and use a heart cookie cutter.
