Unwrap chocolate candies and place pretzels in a single layer on a parchment-lined baking sheet.
Place one chocolate candy on a pretzel.
After every pretzel has a chocolate candy, place the baking sheet in the oven for about 4-5 minutes. The chocolate will be shiny and soft.
Remove the pan from the oven and gently press a pecan on the top of the chocolate candy, pressing down slightly. You don't want to completely squish the candy, just press down about halfway.
