Homemade Marshmallows Recipe

When I made my first batch of homemade marshmallows last winter, everyone went crazy for them. I have never been a big fan of marshmallows, but I am a huge fan of hot cocoa and topping it with homemade marshmallows is the best way to drink hot cocoa. In my opinion of course. 😬 If you are a marshmallow fan and haven’t had homemade marshmallows then you are missing out! They are so fluffy {insert Agnes voice from Despicable Me}. And my oldest son loves them and he is a tough critic. 😂

This recipe may sound intimidating, but homemade marshmallows are actually super simple to make. Messy, but simple.


1.5 cups of granulated sugar
3 (1 oz) packets of unflavored gelatin
1 cup of cold water (divided)
1/4 tsp salt
1.5 tsp of peppermint extract
1 cup of light corn syrup
Non-stick baking spray
Powdered sugar for dusting

I don’t ever measure the powdered sugar. I just use enough to dust the pan after applying the baking spray and then enough to dust the marshmallows to set and then again before cutting.

Baking tools

Electric mixer
Medium sized sauce pan
1 – 12×18 cookie sheet
Wooden spoon
Rubber spatula
Measuring cups
Cutting board
Cookie cutters (optional)
Food coloring pens (optional)
Royal Icing (optional)

Step 1: Pour the unflavored gelatin and 1/2 cup of the cold water into a small ramekin.  You’ll use the other 1/2 cup of water for the sugar mix. Set aside and allow the unflavored gelatin to bloom while you heart the sugar mix.

Tip: Make sure the gelatin is mixed in with the water well. If not the gelatin will clump up and get rock hard.

Step 2: Spray the cookie sheet with the non-stick baking spray. Then dust the bottom and sides of the cookie sheet with powdered sugar.

Step 3: Add the other 1/2 cup of water, granulated sugar, salt, and light corn syrup to a medium-sized sauce pan, then turn the burner on medium heat. Stir the contents intermittently until the sugar mix is dissolved. Should take about 5-10 minutes.

Step 4: Using a rubber spatula, pour the gelatin mix into the electric mixer. Then slowly add the sugar mix with the mixer on medium speed. After the sugar mix has been added, add your choice of extract (I used peppermint) then turn the mixer on high and beat until stiff peaks form. This will take about 15 – 20 minutes.

Step 5: Pour the marshmallow mix onto the cookie sheet and spread evenly using the rubber spatula.

Step 6: Dust the top of the marshmallows with powdered sugar and let them set over night.

Step 7: Once the marshmallows are set, dust the top of the marshmallows and the top of your cutting board. At this point you can cut the marshmallows into squares or use cookie cutters.

For the cookie cutters, I used a mini gingerbread man, star, and a donut cutter (only using the center hole) for the snowman face. My donut cutter looks like the one in the photo below.

Step 8: Using a knife (for squares) or cookie cutters, cutout all the marshmallows directly from the cookie sheet ,  then dust all the marshmallows (sides, tops, bottoms) with powdered sugar.

Tip: The powdered sugar will prevent the marshmallows from sticking to one another, which is why I dust them so much.

Step 9: If you chose to cut squares, you’re done! Enjoy with a nice cup of hot cocoa.

If you want to use cookie cutters along with decorating the marshmallows continue following the directions.

Step 10: Make a batch of royal Icing. CLICK HERE for my recipe. I did switch out the extract I used in my original royal icing recipe for peppermint extract to make the marshmallows extra peppermint-y. 🤗

Since I made gingerbread men and snowmen, I used orange and brown food coloring. I also used red & black Wilton food coloring pens. Honestly, I would have just used food coloring pens for everything, but I couldn’t find any orange or brown pens, so I went to plan B with the royal Icing. 😊

Step 11: Decorate the marshmallows then allow the icing and food coloring to dry completely (about 1 hour). Once the icing is dry to the touch, serve on top of hot cocoa and enjoy! I got the idea to make the snowman face from Williams-Sonoma. Aren’t they so cute? ⛄️

  1. This is amazing! Thank you! If I were to wrap them up to gift with a mug and hot cocoa mix, how long will they last? Or is it more of a day of type of thing?

    1. Hi! Thanks so much! We have eaten them up to a week old. I wouldn’t go any longer than that. I would make them a couple days before gifting. ❤️ Hope that helps! Merry Christmas!
