Peanut Butter Muscle Brownie? As in, a brownie that not only has peanut butter flavor, but also has protein? I thought it was too good to be true- but in fact, it was really good! Lenny & Larry's Peanut Butter Muscle Brownie was quite a treat. There was a thick and chocolatey brownie, covered with a creamy peanut butter drizzle. The brownie part was chewy, moist, a bit dense, and actually quite sweet. It was actually a tad too sweet for my preferences, but still tasty. The peanut butter drizzle on top was the best part! It was creamy, and had more of a sweet than salty peanut butter flavor. Some of the peanut butter topping stuck to the wrapper, but that didn't take away from the overall enjoyment for me! Overall, I would surely eat this again. I was a bit disappointed that there was 12 grams of sugar and only 1 gram of fiber per 40 grams. Also, the brownie I got had TWO servings per brownie, and it was too delicious to NOT eat the whole thing! On the positive side, it did satisfy my hunger, and was a very delicious treat!
