Same question - would love to make this with dark chocolate using a great cocoa powder and melted chocolate - can it be done?

Hi HR!

Copying my answer for JSB here too:

I totally think so! I will say, you may add to need a bit of sweetener because jumping from milk to dark is drastically decreasing the amount of sugar in the filling. If you are all about bitter chocolate flavor I'd say go for it as is.

If not you could add a tablespoon or two of a liquid sweetener like honey or maple syrup to balance things out.

Hope this helps!
