Any websites I've seen www.beautifulcookies.com
, elenis's in NYC (don't know address) all charge at least $2.50 per cookie (eleni has some that are $10.00!!).
They are a lot of work, if you do flooding and details. If you just sprinkle them with sugars, I can see that you'd charge less, but if you do all the time-consuming details, then you are undercharging at $7.50 a dozen.
I don't know how much ingredients cost where you are, but butter is very expensive for me, so is running my oven, so is all the time I spend decorating. There is also down time, where you have to wait for one layer to dry before you can add details.
$7.50 divided by 12 cookies is 63 cents! COokies cost me about 40 cents each, so you you are making a grand total profit of 23 cents per cookie!!! For all that work! WAIT!! I haven't even included lollipop sticks, a container, cello bags, cello wrap for the basket, ribbon etc. I would venture that you are either breaking even at those prices, possibly even losing money.
If it's a hobby and you're just practicing, okay you don't need a lot of profit. If, later, you decide to do it as a bit of a money maker, you'll have a hard time raising those prices to where they should be.
Decorated cookies are considered gourmet, so at this point, they should be more expensive. Plain Choc. Chip cookies from my supermarket bakery cost about $6 a dozen.
Please don't undersell yourself. Check out the websites - it will boost your confidence. Even at $2 or $2.50 per cookie, yours would be a bargain!
