Place 1/2 cup white chocolate chips in a glass bowl along with 1/2 tsp coconut oil. Microwave on high for 1 minute. Let sit in the microwave for an additional minute. Stir gently, then return to the microwave for 15 seconds, if needed.

Place remaining 1/4 cup white chocolate chips in a small baggie. Microwave for 45 seconds, or until warm and soft.

Dip each pretzel into the bowl of white chocolate, gently tapping the edge of the bowl to release excess chocolate. This process is so much easier when you use a dipping tool! Lay the covered pretzel down on a piece of wax paper. Place candy eyeballs into the top 2 cavities in the pretzel. Let cool until solid.

Take the baggie of white chocolate and snip the corner. Pipe white chocolate onto the top of each coated pretzel in lines, criss-crossing the entire "face" going around each eye. Let cool until solid.

Repeat the process until you have the desired amount of mummy pretzels, re-heating up the chocolate as necessary. Store in an airtight container to save.
