01 - Line a baking sheet with parchment or wax paper to prevent sticking.
02 - Place chocolate chips in a microwave-safe bowl and melt in 30-second intervals, stirring between each interval, until fully melted and smooth (approximately 1-2 minutes total).
03 - Dip each pretzel halfway or fully into the melted chocolate, allowing excess to drip off before placing on the prepared baking sheet.
04 - Immediately sprinkle heart-shaped sprinkles over the wet chocolate coating on each pretzel.
05 - Allow pretzels to set at room temperature for 30 minutes, or refrigerate for 10 minutes until the chocolate is completely firm.
