I use the Bella Cucina Rocket Blender to make my smoothies.
This one is sooo good, idk why I didn't think of using coconut butter before. It doesn't need sweetener, I guess coconut butter is naturally sweet? I read the label and it didn't say any added sugars. Anyway.
four big spoonfuls of greek yogurt, maybe 1/2–1 cup?
two big spoonfuls of coconut butter, maybe 2 tablespoons–1/4 cup?
enough water to cover the mango
Put enough frozen mango to half fill the blender cup, then the greek yogurt, then the coconut butter, and then water. Screw on the cap, stick the cup on the motor base, and blend for 30 seconds. Then take it off the base and give it a little shake to get anything that's stuck on the top of the cup. Blend for another 20 seconds or until the smoothie is churning freely from top to bottom.
