Yes for 10m, for sure
The Math will be explained shorty…
Ok here it is
A regular subway cookie costs .33 (as you get 3 for $1)
Now a regular subway cookie is about the size of your hand, this cookie is the size of a midsized SUV much like this:

Now the sugar required to build a cookie of this size would be around 1 ton (Just an estimate, and provided that the buyer doesn't mind having diabetes) 5 pounds of sugar costs $3 (where I live) so 1 ton (2000 pounds would estimate to around: $1200 USD) Then buying the eggs around 500 eggs? Just a rough estimate, should be around there (500/12 = 42 ish x 3 = $126 dollars) chocolate chips 16oz bag (1 pound) = $2.50 uhh aprox 100 pounds needed? 2.50 x 100 = $250) We are going to need butter, about 500 pounds of it (Yes you need a lot of butter) 500 x $2 = $1000 USD..
Total costs:
$2576 at its cheapest
Using real measurements we are looking towards nearly $5000, more if we needed cooking supplies to cook something that big and the amount of blow torches to cook it on the ground because there is no oven that can hold a cookie of that size.
So a realistic measurement of cost would be around $20000 USD
Now he is selling us the cookie for 10m x .33 = $3.30
Pretty solid deal.
