Good flavor like macro balance of fat carb protein

I like the taste of these a lot. They are pretty filling because they have 15 g of fat and 15 g of protein. They have 13 g of carbs with just two added sugars. They are a little hard, but I put them in the microwave for about 12 seconds and they are wonderful.

New recipe - I'm a fan!

I was a bit worried that the recipe change meant this was morphing into a mainstream "candy bar with protein sprinkled on top"... nope... this is the bar I always loved, but a bit chewier :) well done!

Very dense bar is quite difficult to chew. Basically just like an RX bar. I’d hoped for something so much more satisfying!

Too hard

The flavor of these bars is good, kind of like a tootsie roll, but they are too hard to bite. I ended up cutting them into bite sized pieces; about 12 per bar.
