Pumpkin Spice Marshmallows

I love making marshmallows from scratch.  I never thought I would because they seem so intimidating, but they’re surprisingly easy! You do need a candy thermometer, but they are super cheap and easy to use.  A stand mixer also makes it a lot easier, but you can definitely still make them without one. But the absolute best part about making marshmallows from scratch is that you can make them all sorts of delicious flavors! And I can’t think of a better flavor to liven up your cozy fall beverage than Pumpkin Spice Marshmallows!

How to prepare your pan

Line an 8×8 pan with parchment paper. Spray with nonstick spray.  In a small bowl, combine powdered sugar, cornstarch, and pumpkin pie spice.  Sprinkle half this mixture on the bottom and sides of the pan.  Save the rest of the mixture to cover the top of the marshmallows.

How to make Pumpkin Spice Marshmallows

You start by placing gelatin and water in your mixing bowl and setting that aside. You’ll then heat sugar, corn syrup, and water on the stove, first covered for about 4 minutes, and then uncover and continue heating until it reaches 240 F (this is where the candy thermometer comes in). Once it reaches 240 F, remove from heat. You’ll now start beating the gelatin mixture and slowly add in the corn syrup mixture.  Once it’s added, you’ll continue beating for 12 minutes (this is where the stand mixer comes in handy). After 12 minutes, add in pumpkin pie spice, and, if desired, orange food coloring, and continue beating for another 2-3 minutes.

Spread mixture into prepared pan.  Sprinkle remaining cornstarch mixture over top of the marshmallows and let set for about 4 hours. Use a greased knife to cut into cubes, or grease a cookie cutter and cut into fun fall shapes, like pumpkins and leaves!

How to use a candy thermometer

To use a candy thermometer, you simply clip it on to the side of the pot and it does all the work! You want to be sure the tip of the thermometer is in the mixture, but not touching the bottom of the pot. And be careful when you remove it because it can get hot to the touch. I always use a potholder to take it off the pot.

These Pumpkin Spice Marshmallows are so delicious in coffee or hot chocolate, but are also super delicious to eat straight from the pan!  They make great gifts – a perfect back to school treat for teachers!
