Cook It – Halloween Marshmallow S’mores

filed under

I am so excited to share my Halloween S’mores recipe with you all today. You may recall a month or so ago when I posted about how to make swirly mint chocolate S’mores. This recipe is a take on those, but with a Halloween twist. Who says S’mores are just for the summer anyway?!

To make your homemade Halloween marshmallows:


  • 3 packages unflavored gelatin (1/4 ounce packets)
  • 1 cup water
  • 1 1/2 cups sugar 
  • 1 cup corn syrup
  • 1/4 tsp kosher salt
  • 1 tsp vanilla extract
  • 1/2 cup powdered sugar mixed with 1/2 cup cornstarch for dusting
  • food coloring in Orange, Black, and Lime/neon Green
  • 8×8″ Pan


1. Prepare your pan and mixing bowls with spoons for mixing the
colored marshmallows (I left some of my marshmallow white and just kept that in the big mixing bowl). To prepare the pan, spray with cooking spray and
then dust with the cornstarch and powdered sugar mixture to coat the
entire pan.
2. Mix the gelatin and 1/2 cup of water in your mixing bowl and let sit so the gelatin can bloom
3. Mix the rest of the water, sugar, salt, and corn syrup in a pan and heat
over medium heat until the sugar dissolves. Once the sugar dissolves,
raise the temperature to high and use a candy thermometer to get the
sugar mixture to 240 ºF (about 7-8 minutes).
4. When the mixture reaches the temperature, turn on the mixer and mix
the gelatin mixture. Slowly stream the sugar mixture into the mixer on
medium speed. Once all the sugar has been added, increase the mixture
speed and mix for apps. 6 minutes. Then you will added the vanilla extract and mix for another few seconds until well combined.
5. Divide the marshmallow mixture into the bowls and add your food
coloring and mix until combined. Make sure to keep some of the marshmallow mixture white! You will want to work quickly before
the marshmallows start to set up.
6. Once the marshmallows are mixed, start by dropping dollops of each
color into the pan. Once they are all added to the pan, use a chopstick
or spoon to gently swirl the mixture to create a marbled effect. Kids love this part (as you can tell from the little hand doing the swirling for me).
7. Dust the top with more of the powdered sugar mixture and let set for several hours to overnight to set up.

Once the marshmallows have had time to set, use kitchen scissors or a sharp knife to cut into squares. Then pair them with some melted black candy melts and chocolate graham crackers to complete the Halloween look.

Not a s’mores fan ( and if you aren’t, then we need to have a talk!)? These marshmallows are so fun that they would be great to just eat plain as well. Oh and as you can see above, be careful when melting the marshmallows as they tend to be more gooey and melt-y than store bought ones! But they taste soooo much better!
