  • Place 1/2 c of the warm water into a large bowl. This needs to be large enough as you'll be mixing the marshmallows in this bowl. Otherwise, you'll have a mess!
  • Sprinkle the gelatin on top of the warm water and whisk until incorporated, set aside.
  • In a medium sauce pan, place remaining 1/2 c of water, powdered sugar substitute and salt over medium low heat. Whisk the ingredients until it becomes translucent. Remove from the heat as soon as you see bubbles begin to form.
  • Pour the warm mixture into your large mixing bowl. Using a hand mixer or stand mixer with a whisk attachment, whisk for 15-20 minutes until the color changes from light brown to white, you have a little air in the mixture and forms stiff peaks.
  • Place parchment paper in a 8x8 baking dish.. Dust with powdered sweetener to help prevent sticking.
  • Pour marshmallow mixture into prepared baking dish and refrigerate overnight. The dough should become firm and not sticky on the top.
  • Remove from the pan using the parchment paper. Coat your sharp knife in a bit of powdered sweetener and cut into your marshmallows, making 16 squares. If the dough seems a little sticky, you can dust the marshmallows in a little more erythritol to prevent sticking when storing. Store in an airtight container.
