Peanut Butter Marshmallow Recipe

With autumn upon us, cooler weather is around the corner! (Thank goodness!!) With the cooler weather comes the overabundance of pumpkin-flavored this and that… and backyard campfires! (can you say “‘smores”?!)

To add an interesting and tasty variety to your ‘smore making, check out this peanut butter marshmallow recipe – perfect for those that like their chocolate with peanut butter.


  • 4-1/2 tsp unflavored powdered gelatin
  • 1/2 cup cold water
  • 3/4 cup sugar
  • 1/2 cup light corn syrup
  • 1/4 cup water
  • 1/8 tsp salt
  • 2 tsp vanilla extract
  • 3 Tbsp creamy peanut butter
  • 1 1/2 cups confectioners’ sugar
  • 1 cup cornstarch


  1. Lightly coat a 7 X 11-inch baking pan with cooking spray. Use a paper towel to wipe and coat the surface of the pan evenly.
  2. Add gelatin to a bowl of cold water. Whisk together and let soften for about 10 minutes.
  3. In a 1-1/2 quart saucepan, stir together the sugar, 1/4 of the corn syrup, water, and salt over high heat.
  4. Boil, stirring occasionally until the temperature reaches 240 degrees F on a candy thermometer. (Make sure the tip does not touch the bottom of the pot)
  5. While boiling, pour remaining 1/4 cup of corn syrup into the bowl of an electric mixer fitted with the whisk attachment. Microwave gelatin on high for about 30 seconds. Stir again and pour into the mixer bowl. Set the speed to low and keep it running.
  6. When the syrup reaches 240 degrees F, slowly pour it into the mixer bowl.
  7. Increase speed to medium and beat 5 minutes.
  8. Increase speed to medium-high and beat 5 more minutes.
  9. Increase speed to highest setting and beat 1-2 minutes.
  10. Beat in vanilla.
  11. Place peanut butter into a small bowl and add a quarter of the batter. Quickly stir until well blended. Scrape the peanut butter mallow back in the mixer bowl with the vanilla batter. Use a large spatula to gently fold the two batters together until mostly blended.
  12. Pour into prepared pan, using an offset spatula to quickly smooth it out.
  13. Sift classic coating evenly and generously over the top. Let sit for at least 6 hours in a cool, dry place.
  14. Use a knife to loosen the marshmallow from the edges of the pan. Invert onto a coating-dusted baking sheet. Dust with more classic coating.
  15. Cut into squares or use a cookie cutter. Dip sticky/cut edges of marshmallows into the coating and dust off any excess. Or drop several coated mallows in a sieve and shake off any excess.
  16. Store in a cool dry place in a pan with the lid slightly ajar to allow air flow. If the mallows resist drying, you can simply dust with more coating for any edges that are damp.
