Line a large baking sheet with parchment paper. Arrange the pretzels in an even layer on the prepared baking sheet.
Melt the chocolate in the microwave, or using a double boiler. Drizzle chocolate over the pretzels, working in sections, then sprinkle immediately with toffee bits. Repeat until all pretzels are coated.
Let stand until chocolate is set, or place pretzels in freezer for a few minutes to set quickly.
