As you can see, the Thumbs Up is round like a cigar (or a thumb!) It definitely has the "Butterfinger crunch" that you remember. You know, the peanut buttery part that gets stuck to your back teeth? It has been reproduced faithfully. What I noticed taste-wise was the strong peanut butter flavor and a resounding sweetness. I personally would have liked it a little less sweet. I never thought I would say this, but it seems the excessive sugar takes away from the chocolate. I also would have liked to see a thicker chocolate coating.
Overall I enjoyed the Thumbs Up Candy Bar. It seems a little too sweet for me but I love how crunchy it is and the rounded shape is cute. If you miss Butterfingers, you should definitely give it a try. Now do Go Max Go a favor and tell them in the comments what candy you would like to see them Veganize next! Vegan Kit Kat anyone?
