  • Meanwhile, in a sauce pan set on medium, combine together your sugar alternative, optional salt  and the remaining water. Stirring as you go, allow this to just about bubble( 8-10 minutes). Remove this from heat and stir in the vanilla extract.

  • Now, start your mixer on slow (whisk attachment works best for me) with the first bowl that you had set aside. Gradually pour the contents of the second bowl along the inside of the mixing bowl. Allow the mixture to double in size- takes about 12-14 minutes in the mixer.

  • Once the mixture has doubles in size, you can pour it into your prepped baking dish. Some folks like to sprinkle additional powdered sugar (alternative) on top of this. Allow it to cool uncovered before cutting into squares.

Recipe Notes

I mentioned above that it is preferred that you use unsweetened unflavored gelatin that comes in packets. This is because it is already measured out for you.
Also mentioned above was that these marshmallows can be personalized as well.
Change things up a bit by using another extract instead. Maple extract, mint extract, or banana extract are good examples of this.b
Also, you could add a few drops of food coloring to make your marshmallow look even prettier!
