1Line an 8-by-8-inch pan with parchment paper. Make sure the parchment paper goes up all the sides.
2Grease the parchment paper with coconut oil as well to prevent sticking.
3In a bowl, add the 1/2 cup of cold water. Sprinkle the agar agar powder in. Let it sit for 10 minutes.
4In a small saucepan, add in the 1/2 cup warm water with 1/4 cup of erythritol and a dash of stevia, to taste. Add in the vanilla extract and salt as well. When it just starts to boil, take it off the stove.
5Start mixing the agar agar mixture with an electric whisk slowly while adding in the hot liquid.
6Keep whisking and increase the whisk speed. The agar agar mixture will turn white and foamy after around 10 minutes.
7Keep whisking for 10 minutes more until the mixture doubles in volume. Pour quickly into the prepared container and smooth the top with a greased spatula.
8Refrigerate the container overnight to set properly.
9Cut the low-carb marshmallow into cubes with a good knife (grease the knife with some melted coconut oil first to prevent the marshmallow from sticking to the knife).
