Firstly nice work,

What do the colours represent? I view them as green is a mint flavoured one and red is dark chocolate... Is this the case? Or are they general christmas colours?

2 is the weakest - however if the chocolates are going to be sold at christmas only, the #2 has the only direct link to christmas via the snowflake.

I like #3 the best but only if the colours relate to a flavouring... if it doesn't then I prefer the #1.

I have just squinted at the image - and can see that the green is dark chocolate and red is milk chocolate???? If that is so, I would revise the green colour as green in a chocolate wrapper shouts out MINT.

You may want to try and use the snowflake with more subtly to bring a christmas element to the design.
