This is my every night go-to. It’s a staple. Excellent rich texture.

Ingredients
1/2 avocado
1/2 banana
1.5 scoops chocolate casein or 1 scoop casein and .5 scoop chocolate whey (The more casein, the thicker and denser the product. More whey = lighter, mousse-like.)
70g frozen mixed berries (a little more than a quarter cup)
3/4 cup water
3 ice cubes
cinnamon to taste

Preparation
You’ll need a very strong, small blender for this with a small cup so that the final product is smooth. I use a NutriBullet (600 watt motor) with the small (18 oz) cup.

Add avocado, banana and most water, followed by berries, ice cubes and finally protein powder topped with a little more water and cinnamon. Order is important. protein should be closest to blade so that it gets completely incorporated. Blend until smooth (around 20 seconds in the NutriBullet). If the blender chokes, add a little more water. I eat right out of the blending container.
