How to Make Fluffernutter Snack Mix, Step By Step

Step 1. Prep a sheet pan with parchment paper. Measure out Snack Mix Mix-ins.

First, line a large sheet pan with parchment paper. 

Grab a large bowl and start measuring out the mix-ins for your fluffer nutter snack mix. The base of fluffer nutter mix is a blend of salty, nutty, and sweet snacks. Use your hands or a couple of spoons to toss the mixture together.

To give the mix that iconic Fluffernutter taste, we added Nutter Butter bites, mini marshmallows, and roasted peanuts. The addition of popforn, chex, and ruffled potato chips adds more saltiness, texture, and body to the mix.

Step 2. Melt white chocolate on the stovetop or in the microwave.

Next, carefully melt white chocolate chips on the stovetop or in the microwave. White chocolate can be a bit more temperamental than dark or milk chocolate, so you will need to watch it carefully to avoid any burning or clumping.

Here’s what to do when melting the chocolate in a double boiler or microwave:

• Melting chocolate on the stovetop. A double boiler is the best way to get smooth, melted chocolate without it burning. If you don’t have a double boiler, you can melt the chocolate in a small saucepan. If using a double boiler, bring the water to a boil before adding the chocolate chips to the top pan of the double boiler. If using a saucepan, melt the chocolate on low. For both stovetop methods, stir continuously until melted.
• Melting chocolate in the microwave. If you’re looking for an easy way to melt chocolate that requires less cleanup time, we recommend using the microwave. Heat the chocolate chips and in 30-second intervals, stirring between each heating. Once the chocolate is almost melted, remove it and stir until all of the chocolate is melted. 

Once the white chocolate is just melted, remove from the heat and pour over the snack mix.

Step 3. Coat the snack mix with white chocolate and chill.

Pour the melted white chocolate over the snack mix and use a spoon or rubber spatula to stir and coat the mixture with chocolate. 

Once the mixture is evenly coated, pour the snack mix onto the parchment-lined baking sheet in an even layer. 

Chill the mixture in the fridge for about 15-20 minutes to harden. Once the chocolate is has hardened, break larger chunks into smaller pieces and serve. 

Tips for making Fluffernutter Snack Mix

• Use a pre-popped unseasoned popcorn. We recommend using a pre-popped packaged popcorn for this snack mix. You won’t have to worry about having fewer kernels, and easier to measure and add to the mix.
• If melting chocolate on the stovetop, stir the chocolate continuously. It’s important to stir the chocolate with each of these methods so that the chocolate melts evenly.
• If melting chocolate in the microwave, heat in 30-second intervals and stir between each heating. This will be the best way to even out the heating as you melt in the microwave. It will also help to avoid burning or clumping.
