I've had hemp protein powder once before, and it tasted AWFUL. Maybe I could do some protein powder instead? I don't remember how hemp powder "acted" so I don't know for sure how the switch would be.
Here's a recipe for another chia seed "pudding" (the author compares it to Tapioca pudding which I've always loved!) and it's pretty similar to yours (chia seeds, plus liquid, plus flavoring). I find jay robs stevia sweetened protein powder to be excessively sweet/overpowering, so maybe I'll replace some of the cocoa powder in this recipe with the chocolate protein powder to give me some sweetness and protein.
I do like, though, that your recipe uses water (because of the fillers in almond milk unless it's homemade) and because using a nut butter could give it a taste bonus.
Anyway, either recipe/combo of either one, sounds like something good to make a large batch of and eat for a couple quick meals for the week!
