Blend the ice cream ingredients together and pour into a freezer-safe bowl/container (put it in the freezer until you're ready to pour the frosting mixture over it).
Combine the frosting swirl ingredients and drizzle over the ice cream, swirling it in just a little with a spoon. Return the bowl to the freezer for 45 minutes to an hour.
Stir twice within the first 30 minutes for the optimum texture and more even freezing. Serve when the ice cream reaches the desired consistency. If it gets too hard, just defrost for a little bit in the microwave.
I love to eat this with some natural peanut butter on top (THM:S).
Notes
This makes a great S dessert (it makes enough for two people, unless you're really hungry), or you can add a full scoop of protein powder and use it as a meal for one person (if you're in the mood for ice cream for breakfast or something. I get that feeling once in awhile.). My favorite topping for this ice cream is peanut butter (use natural). You could omit the freezing step and just enjoy this as a thick milkshake.
