I recieved a Nordic Bakeware Platinum Series Sunflower Mini Bundt Pan for Christmas. The first trial batch is out of the oven. I used the recipe that was included on the packaging (I omitted the food coloring).
The biggest worry about any bundt cake, and especially a bundt cake in a mold with lots of nooks and crannies like this one is getting the proper release. I simply used a pastry brush to spread oil on the outside. This wasn't ideal since the oil tended to bead up on the non-stick surface. The nordicware site recommends using cooking spray (among other things). I'm not a big fan of sprays with all their aerosol and extra packaging, but I've had success with larger chocolate bundt cakes in the past using a melted butter and cocoa powder paste. I could probably do something similar to that for these lighter-color cakes, but use flour instead.
All in all the cakes still released well. Two of the six released perfectly, and the other 4 managed to hold their shape pretty well. In addition to a better release mixture on the pans themselves I probably could have stood to wait for the cakes to cool in the pan a bit longer.
