Melt the sugar-free chocolate chips and coconut oil in 15-second intervals, stirring between each until smooth.
Spoon or pipe melted chocolate into each cavity of a silicone egg mold, tilting or using a brush to coat the sides evenly. Freeze for 10-15 minutes until set.
Mix ½ cup water and gelatin in stand mixer bowl. Allow gelatin to bloom for a few minutes.
Combine ¾ cup water, powdered sugar-free sweetener, and Keto Chow in a saucepan over medium heat.
Stir continuously until the mixture starts bubbling and the sweetener is fully dissolved.
Carefully pour the hot syrup into the bloomed gelatin while mixing on low speed for 5 minutes.
Increase to high speed and whip for 10 minutes, until light, fluffy, and doubled in size.
Spoon or scoop the marshmallow mixture into each cavity, leaving a small gap at the top. Cover the marshmallow with a thin layer of melted chocolate, spreading evenly to seal the eggs completely.
Return the mold to the fridge or freezer for at least 30 minutes to fully set.
