What is a reasonable bake sale price for holiday cookies?

I made some raspberry shortbread sandwich cookies for a Holiday bake sale and I’m supposed to bring them bagged and priced but I have no idea what to price them at. I want to make money for the fundraiser so I don’t want to under price them but I don’t want to over price them that they don’t sell.

These cookies are essentially two shortbread cookies with raspberry jam sandwiched between them and dusted with powdered sugar. The top cookie has a heart or star shape cut out so you can see the raspberry inside. These are pretty looking cookies and more time consuming since they rolled and cut out and assembled.

I think these could be one of the more higher priced cookies but I don’t know what price they should be. They are packaged four cookies per bag.
They are just over 2" scalloped circles.

These chocolate raspberry cookie things?

At a Chrismas party, I once had these delicious cookie-like things someone made. The batter was made from fudge cake mix, (but not made like cupcakes) it was spooned into mini paper baking cups and filled or topped with some sort of raspberry filling. Anyone have a recipe for this?
They were made using cake mix, but not as directed on the box. Kinda like cookies, but chewy and baked in mini paper baking cups.
They were not the truffle bars someone suggested, but thanks for trying.
