Calories in this Cookies and Dreams Brownie Ice Cream?

Went out and had this (pic 1). It's a double chocolate cookie with frosting and Oreos pieces, plus a side of vanilla ice cream with dusted Oreos.

The square cookie was about 8×8 cm (eyeballing); each ice cream was around the volume in a normal soft serve ice cream cone; frosting was very sweet, but thin.

Very very sorry for not having better measurements and frames of references. Pics 2-3 are for alternative angles from other reviews, and pic 4 is the item as advertised. Thank you everyone for the help!
