At this point, you can pick up that pan, and place it in the fridge for a half-hour or so. You’ll want that chocolate to fully stiffen up, so don’t rush this process.
Meanwhile, while that’s busy getting its chill on, you can continue with the rest of the recipe.
The next step is basically a repeat of the melting process that you just did with the white chocolate chips, but this time, you’ll do it with your semi-sweet ones.
After you remove the bowl of melted semi-sweet chocolate chips from the double boiler, you can also remove that baking pan of newly-hardened white chocolate from the fridge, as well.
Atop that frigid layer of white chocolate, strategically pour in your melted semi-sweet chocolate.
And do your best to make sure it is smooth and evenly distributed. You don’t want any wonky bits. This step ensures that every munch of this bark will be just as good (and as strong) as the last.
When you feel like you’ve adequately smoothed out the contents, you can return them to their refrigerated confines. And don’t even think about taking them out for another half hour or so.
When that time has elapsed, you can remove it from the fridge and pour in the remaining half of the white chocolate that you saved from the first step. But before you toss that baking pan back into the fridge for the third (and final) time, you’ll want to add in your candy canes.
Which, by the way, you should’ve broken up into bite-sized pieces, via a Ziploc bag and any sort of “smashing tool” of your choosing.
When you’ve expertly distributed all of the crushed candy cane remnants throughout this last layer, head on back to the fridge and let this sucker cool out and set for almost an hour.
Then, finally, when it’s reached your desired consistency, you can remove it from the fridge and place it on the counter. Now, you can easily remove the entire sheet of bark from the baking pan, and break it apart into rigid little chunks to enjoy whenever you please. Whatever you don’t eat at first, be sure to keep covered and in a cool, chill place for storage.
Other than that, the only thing left to do at this point is pat yourself on the back for a job well done.
