The small Reese's are the best shape an chockolate/pb ratio. The Trader Joes adult version of these with dark chocolate and real peanut butter are the final form evolution of the candy...then on top of it the Trader Joes versions are $1 for 9 and it's the best candy deal in the universe by miles.
I can get a small candy at a gas station for $3 or I can get 27 of these immaculate perfect PB cups at TJs and absolutely gorge myself.
The dark chocolate pb cups at Trader Joe's are my kryptonite.
