I have also want to add more smoothies because one of my sons will drink anything juiced and the other will eat anything that is in a smoothie. Of course they couldn't make my life easy and both like one or the other!
1/2 cup of old fashion oats
2-3 tablespoons peanut butter
2 tablespoons cocoa powder (unsweetened) ... or more if you like chocolate like me!
1 cup of milk... I used 2% regular milk but I think soy, almond or coconut would all taste yummy
2 frozen banana (slightly thawed to remove peel)
1/2 cup of ice
I blended the oats first in a the blender to a powder and then added the remaining ingredients until it was a milkshake consistency. Very simple. I like it very thick, the rest of my family like it a little more diluted with either water or milk. Its almost the consistency of a Wendy's Frosty...
