How to Make Pumpkin Spice Marshmallows
Step 1: Prepare the Pan
Lightly grease a 9×13-inch baking pan and line it with parchment paper. Grease the parchment and dust it with a mixture of powdered sugar and cornstarch to prevent sticking.
Step 2: Bloom the Gelatin
Pour the cold water into the bowl of your stand mixer. Sprinkle the gelatin evenly over the surface and let it sit undisturbed for 5 to 10 minutes until fully bloomed.
Step 3: Cook the Sugar Syrup
In a heavy-bottomed saucepan, combine the granulated sugar, corn syrup, water, and salt. Heat over medium heat until the sugar dissolves. Once the mixture begins to boil, stop stirring and continue cooking until it reaches 240°F (115°C) on a candy thermometer.
Step 4: Begin Whipping
With the mixer running on low speed, slowly pour the hot sugar syrup into the bloomed gelatin. Gradually increase the speed to high and whip the mixture until it becomes thick, glossy, and noticeably increases in volume.
Step 5: Add the Pumpkin Flavor
Once the marshmallow mixture has whipped for about 8 to 10 minutes, add the pumpkin puree, pumpkin pie spice, and vanilla extract. Continue whipping for another 2 to 3 minutes until everything is fully incorporated and the mixture is thick, smooth, and fluffy.
Step 6: Spread into the Pan
Working quickly, pour the marshmallow mixture into the prepared baking pan. Use a lightly greased rubber spatula to spread it evenly before it begins to set. Dust the top with the remaining powdered sugar and cornstarch mixture. For extra fall flavor, lightly sprinkle a little pumpkin pie spice over the surface.
Step 7: Let the Marshmallows Set
Leave the marshmallows uncovered at room temperature for at least 6 to 8 hours, or overnight. Once firm, lift the marshmallow slab out of the pan using the parchment paper overhang.
Step 8: Cut and Coat
Dust a cutting board with the remaining coating mixture. Lightly grease a sharp knife or pizza cutter and cut the marshmallows into squares. Toss each piece in the powdered sugar and cornstarch mixture until evenly coated.
Tips for Soft Pumpkin Spice Marshmallows
- Use pure pumpkin puree rather than pumpkin pie filling.
- Whisk the pumpkin puree until smooth before adding it to the marshmallow mixture.
- Cook the sugar syrup to exactly 240°F (115°C) for the best texture.
- Have the baking pan prepared before whipping, as the marshmallow mixture sets quickly.
- Don’t overmix after adding the pumpkin puree to maintain a light texture.
- Allow the marshmallows to rest overnight for cleaner cuts.
- Coat every side thoroughly to prevent sticking.
- Store the marshmallows in an airtight container once completely set.
Common Mistakes to Avoid
1: Using Pumpkin Pie Filling
Pumpkin pie filling contains added sugar and spices that can affect both the flavor and consistency. Always use plain pumpkin puree.
2: Adding Too Much Pumpkin Puree
Pumpkin contains moisture, so using more than recommended can prevent the marshmallows from setting properly.
3: Skipping the Candy Thermometer
The sugar syrup must reach the soft-ball stage (240°F) to produce marshmallows with the right texture.
4: Pouring the Syrup Too Quickly
Slowly stream the hot syrup down the side of the mixing bowl to avoid splashing and to help the gelatin incorporate evenly.
5: Cutting Before They’re Fully Set
Allow enough time for the marshmallows to firm up completely before slicing. Cutting too early creates sticky, uneven pieces.
Easy Ways to Customize This Recipe

Vanilla Pumpkin Marshmallows

Chocolate Pumpkin Marshmallows
Drizzle melted dark chocolate over the finished marshmallows or dip each piece halfway after cutting.
