Add the non-dairy milk, dates, chopped kale, peanut butter, and frozen banana, in that order, to the container of a high-speed blender. (If your blender isn't as powerful, start by adding the non-dairy milk, dates, and chopped kale to the container. Place the lid on and blend until the greens are partially broken down. Then remove the lid and add the peanut butter and frozen banana.)
½ cup unsweetened non-dairy milk, 2 Medjool dates, 1 cup kale, 1 Tablespoon natural peanut butter, 1 frozen banana*
Place the lid on and blend until completely smooth, using the tamper, as needed. (The tamper is the stick that comes with your blender that assists with pushing ingredients toward the blade.)
Pour in a glass and enjoy right away.
Notes
*For the best results, use a ripe banana that has some spots on the peel. Peel and freeze the banana in halves or slices in advance.
