Spread the nuts in a single layer on a baking sheet and bake for 7-10 minutes. Using a spatula, spread them around to check doneness. Bake in two minute increments until done (they will be golden and smell nutty, but not be black and burned).
While the nuts are baking, add the candy canes to your food processor. Blend until no pieces are bigger than a pea. Set aside.
When they're done, immediately add the nuts to the food processor and blend until completely smooth, scraping down the sides as needed.
Add the white chocolate chips, again blending until smooth.
Add salt and vanilla extract to taste, then add the candy canes and pulse until incorporated.
Store in an airtight container in the refrigerator.
