How many calories in a snickerdoodle from paradise bakery?

It depends on the recipe and the size, so there really isn't one definite number. On average, though:

a small snickerdoodle - 90-100 calories,

a medium or regular-sized snickerdoodle is 150-180 calories,

a large is 220-250 calories,

and an extra-large snickerdoodle is about 250-300 calories.
