Place a heat proof bowl over a saucepan filled with water (or use a double boiler). Pour the chocolate chips in the bowl over medium heat.*
Stirring constantly, heat chocolate mixture until smooth and melted. Turn off heat.
Add coconut milk, sweetened condensed coconut milk, cacao powder, vanilla extract, and salt. Mix well and freeze for 1 hour. (This is so that walnuts, chocolate chips, and vegan marshmallows don't sink to the bottom.)
Fold in walnuts, vegan marshmallows, and chopped chocolate chips. Place back in the freezer.
Notes
*When melting the chocolate chips make sure the bowl isn't touching the water. You want the steam to heat the bowl and melt the chocolate.Alternatively, you can heat chocolate chips in the microwave at 30-second intervals until melted. Just make sure to not get any liquid in the container. An 11.25-ounce can of Nature's Charm sweetened condensed coconut milk has 1 cup of Sweetened condensed coconut milk in it, so you'll use half the can.If you use another brand or homemade, make sure to measure ½ cup.This Vegan Rocky Road Ice Cream recipe will last up to a month in an airtight container in the freezer.
