In a medium mixing bowl, whisk together 1 1/2 cups Heavy cream, 1 cup Whole milk, 3/4 cup Granulated sugar, 1/4 cup Unsweetened cocoa powder and1 1/2 teaspoons Vanilla extract until smooth and fully combined.
Pour the chocolate base into a Ninja Creami pint container, leaving some space at the top for expansion. Freeze for at least 24 hours until completely solid.
Once frozen, remove the container from the freezer. Use the Ninja Creami to process the base according to the manufacturer’s instructions. Once creamy, add 1/2 cup Mini marshmallows , chopped 1/2 cup Almonds, and 1/2 cup Semi-sweet chocolate chunks .
Process the container again using the “Mix-In” function on your Ninja Creami to evenly incorporate the marshmallows, almonds, and chocolate chunks into the ice cream.
Scoop into bowls or cones and enjoy immediately, or refreeze for a firmer texture.
