Lay out a sheet of wax paper on a flat surface for placing the finished pretzels after assembly.

Break the white chocolate almond bark into squares and place them in a microwave-safe bowl. Microwave for 1 minute, then stir. Continue heating in 30-second intervals, stirring after each until the chocolate is fully melted and smooth.

Using a piping bag, Ziploc bag with the corner snipped off, or a small spoon, carefully fill the center of each pretzel with the melted white chocolate, aiming to create a heart shape.

Immediately after filling each pretzel, sprinkle heart-shaped sprinkles over the chocolate before it sets. Work in batches of about 5 pretzels at a time to ensure the chocolate doesn’t harden before sprinkling.

Let the pretzels rest at room temperature for 20-30 minutes until the white chocolate is completely hardened and set.

Once firm, serve the pretzels immediately or store them in an airtight container at room temperature for up to several days.
