Twix Dark features the same shortbread cookie and caramel as a regular Twix bar but comes covered in dark chocolate instead of milk chocolate.
You can find the new candy bar in 1.79-oz single packs with a suggested retail price of 99 cents to $1.09 and in 3.02-oz "4 to Go" packs for a suggested retail price of $1.69 to $1.79.
According to Mars, dark chocolate is "considered a more permissible treat" than milk chocolate.
