Sabrina’s Tips

Let your bars cool completely before slicing them. You can also chill them in the fridge for a while to get the best clean cuts for your bars. Clean your knife and coat with a non stick spray to prevent the marshmallow from sticking. You may need to wipe clean between each cut.

About this Recipe

Pumpkin Fluffernutter Bars are the perfect bar for the fall season and the beginning of all the pumpkin flavored treats. These bars are gooey, pumpkiny (yes that’s a real word), and perfectly peanut buttery. For this recipe I make Homemade Marshmallow Fluff, but you can use store bought and these bars can be made in no time at all. You just need 2 cups of it. Plus, with the pumpkin spice flavor built into the peanut butter, you’ll love how easy these bars are. If you can’t find pumpkin spice peanut butter at the store, I have an easy way to make your own at home down in my Variations Section too!

Can this be made ahead of time?

Yes, these bars can be made ahead of time and are perfect to have ready for a grab and go snack. The can be kept at room temperature seal in a container for up to 4 days or kept in the fridge for up to one week. They can also be store in the freezer for 1-2 months. Use parchment paper between the layers to prevent them from sticking together. When you are ready to serve, move them to the fridge overnight to allow them to thaw before taking them out to get to room temperature.

How to Store

  • Serve: You can keep bars at room temperature for 3-4 days sealed in an airtight container.
  • Store: These bars can be kept in the fridge, but they can get hard due to the marshmallow fluff. Take them out and let them get to room temperature before serving. They can be kept in the fridge for up to one week.
  • Freeze: Store in the freezer for 1-2 months. Seal in a container with parchment or waz paper between the bars.

  • Peanut Butter and Jelly Sandwich: Make the best PB&J with it paired with blueberry jam. Pumpkin and blueberries go great together!

Variations

  • Chocolate: Add in some chocolate chips to the batter for some added sweetness. You can also melt the chocolate and swirl onto the top of your bars before baking.
  • Pumpkin Spice: Add in cinnamon, nutmeg and ginger into the batter for some extra pumpkin spice flavor that is perfect for fall.
  • Toppings: Top your bars with Homemade Salted Caramel Sauce. Or for some extra crunch, try topping them with roasted nuts, crushed graham crackers or rolled oats.
  • Marshmallow Fluff: If you don’t want to make your own marshmallow fluff you can substitute with one canister of pre-made marshmallow fluff. The recipe above makes 2 cups.

    1. If you click on the link in the post, their website pops up and they have a store locater. Just type in your zip code and it’ll show you retailers around you that carry their product….easy peasy!

      1. The store locator didn’t pop up with a zip code option, just 2 websites that were $16+ for 1 jar. Amazon shows the product at a good price but unavailable. PB&Co site has a good price and it’s available, but shipping for 2 jars is more expensive than the 2 jars! Any other options for this recipe? I have 2 church groups that would love this dessert. Thanks!

        1. It’s a pumpkin spice peanut butter. PB&Co is the best tasting that I’ve had, but I’m sure there might another brand that would be good.
