heart-shapedor regular-shaped small pretzels.
Cover a baking sheet with parchment paper.
Place yogurt chips in a heat-proof small bowl and melt on HIGH in the microwave at 10 second intervals and stir every 10 seconds until all are almost melted, stir well and set aside until all are melted.
Add one drop of pink gel food coloring (no water in the food coloring) until you get desired color.
Hold a pretzel at the top of one side, and dip the pretzel into the melted yogurt at an angle. Shake off excess melted yogurt and place pretzel on parchment-covered tray. (If the yogurt begins to set, reheat in the microwave 5-10 seconds.)
Sprinkle the pretzels with colored sprinkles while the melted yogurt is still soft and the sprinkles will attach.
Set dipped pretzels aside until melted yogurt has set approximately 30 minutes.
(To speed up the process, the pretzels can be refrigerated 10 minutes).
