Easy Pumpkin Pie Marshmallow Treats are a fun twist on classic marshmallow treats with a cozy fall flavor. These treats mix the creamy sweetness of pumpkin pie spices with gooey marshmallows and crispy cereal for a delightfully chewy snack. The subtle pumpkin spice flavor gives them a cozy, festive vibe perfect for chilly days or holiday gatherings.
I love making these when I want something quick and sweet but a little different from the usual marshmallow treats. They’re super simple to put together, and I always find that the pumpkin pie spices add just the right touch to make them feel special. Plus, they’re soft and sticky in just the right way, making them a favorite for kids and adults alike.
My favorite way to enjoy these treats is warm and fresh out of the pan, but they also keep well if you like to make them ahead of time. They’re great for sharing at fall parties, packing in lunchboxes, or just snacking while watching a cozy movie. Whenever I make these, there’s always a handful disappearing very fast!
Key Ingredients & Substitutions
Crispy Rice Cereal: This is the main base, giving your treats their crispy texture. If you don’t have crispy rice, puffed wheat or corn flakes work for a different crunch.
Butter: Unsalted butter helps control saltiness and adds richness. You can use margarine or coconut oil for dairy-free versions, but flavor might change slightly.
Marshmallows: They melt to create the gooey binder. Use regular sized marshmallows or mini ones. Vegan marshmallows are a great dairy-free substitute.
Pumpkin Pie Spice: This blend makes the treats taste like fall. If you don’t have it, mix cinnamon, nutmeg, ginger, and cloves yourself.
Vanilla Extract: Adds warmth and depth. If you don’t have vanilla, a splash of almond extract can be interesting but use less as it’s strong.
How Can I Get Soft, Evenly Coated Treats Without Them Being Too Sticky or Dry?
Melting the marshmallows and butter properly is key. Do it on low heat and stir constantly so the marshmallows melt smoothly without burning. Then quickly but gently stir in the cereal to coat it evenly.
- Use a large pot to have enough room for mixing without spilling.
- Once mixed, press the treats firmly but don’t pack too hard or they become dense.
- Use a spatula or wax paper to press so it doesn’t stick to your hands.
- Adding toppings while warm helps them stick without sinking in.
- Let cool completely before cutting to keep squares neat.

Equipment You’ll Need
- Large pot – you’ll melt butter and marshmallows smoothly here without burning.
- Wooden spoon or heat-resistant spatula – helps stir sticky marshmallow mixture easily.
- 9×13 inch baking pan – perfect size for pressing and setting the treats evenly.
- Parchment paper or nonstick spray – keeps treats from sticking to the pan for easy removal.
- Measuring cups and spoons – accurate measurements make sure your treats turn out just right.
Flavor Variations & Add-Ins
- Add chopped pecans or walnuts for crunch and a nutty contrast to the soft treats.
- Mix in mini chocolate chips for a sweet twist that melts slightly into the marshmallows.
- Use cinnamon or ginger instead of pumpkin pie spice for a simpler warm flavor.
- Stir in dried cranberries or raisins for chewy bursts that balance the sweetness.
