Absolutely! In fact, we tried almond butter to see whether it affected the flavor. We are happy to report that it not only worked just fine as a viable peanut butter substitute but it also enhanced the overall flavor of the protein bars. If you’re not a fan of almonds, you might not appreciate the taste. But we love almond butter and can confidently say that it works wonders in this recipe. Don’t be afraid to experiment with other peanut butter alternatives if you’re not a fan of almond butter.
