Place the semi-sweet chocolate in a bowl and place it in the microwave uncovered for 30 seconds.
Remove the bowl from the microwave and stir, moving it around so it melts evenly.
Place it back in the microwave for an additional 30 seconds.
Stir again if any of the chocolate has not fully melted. Place it back in the microwave for 10-15 seconds until fully melted.
Repeat the same steps for the white chocolate.
Set up a cookie sheet lined with parchment paper or aluminum foil. Alternatively, you can also use a pastry mat, although the parchment paper makes for much easier cleanup.
Dip the pretzels in the melted chocolate, covering both sides of the pretzel.
Allow any excess to drip off and place flat on the baking sheet.
Repeat the process until all of your pretzels are covered in chocolate.
Once all the pretzels are coated, use a spoon to drizzle the opposite color chocolate over top of the pretzels for contrast.
Sprinkle the pretzels with colored sprinkles or dip them in mini M&M’s or chocolate chips for an indulgent option.
Place the chocolate-covered pretzels in the refrigerator for 30 minutes until the chocolate has fully cooled.
Once cooled, gently remove from the wax paper and plate to serve. If giving as gifts, place them in small plastic bags and tie with ribbon.
These pretzels do not need to be refrigerated, although you want to keep them in a cool, dry place so they do not melt or get stuck together.
