This is a good recipe...but to cut more calories and sugar while still adding flavor this is what I use:
1 level scoop chocolate slim fast powder
1 cup (8oz) soy almond milk unsweetened
2 tbsp. peanut butter powder (found in health stores)
1/2 frozen banana (optional)
and 4-6 ice cubes if not using banana (or as many to your liking)
Mix all ingredients in a blender until smooth, enjoy!
I only use peanutbutter powder because it has 45cals. per 2tbsp., 1gram of sugar compared to the store prepared peanutbutter and I use the almond soy milk unsweetened since there's no sugar or calories. So all together this a little over 200 calories all together and almost 300 calories w/ banana!
I pretty much followed your recipe, but I did double it for the 2 of us, then substituted 2 frozen bananas for the ice, which gave it a creamier texture than you'd intended, I'm sure, but it was wonderfully tasty! Loved the chocolate & PB combo! [Made & reviewed for the closing of Pick A Chef event]
