Peanut Butter & Chocolate Protein Squares

Consuming enough protein can help to support muscle building and recovery, maintain or improve muscle mass, and support weight management.

Protein bars have become a very popular and widely available product, with many different brands, tastes, and other variations to choose from. Among the flavors, peanut butter and chocolate have proven to be one of the most popular and well-received products across many protein bar brands. The number of options for consumers can appear overwhelming and a variety of factors can inform an individual’s choice.
