Peanut Butter Cup Smoothie

A while back, a reader left a comment asking if I had a peanut butter cup smoothie recipe.

I did not.

I did a little research, but really couldn’t find one that spoke to me, so I came up with my own.

When I think of peanut butter cups, I think of the chocolate shell that surrounds them. They’re sweet, but also slightly salty, and that’s what I’ve tried to replicate here.

Instead of blending in chocolate powder, I suggest melting a portion of a quality chocolate bar (45 seconds to a minute in the microwave will do this) and layering it throughout the smoothie.

This is definitely a meal replacement smoothie – it is not  at all low calorie. If you want to reduce the calories for a snack, halve the protein powder, avocado, banana and peanut butter. You can also omit the protein powder altogether if you don’t have it on hand.
