In a medium-sized bowl add the white chocolate chips. Melt in the microwave for 20-second increments and stir in between until fully melted.
With a spoon fill each mold ⅓ of the way.
Place an Oreo on top of the white chocolate. Gently press the cookie down until the sides of the cookie get covered.
With a spoon add a tablespoon or so of the melted chocolate on top of each cookie.
Use a toothpick and spread the melted chocolate over the cookie until the cookie is fully coated.
Gently tap the mold so the cookie is fully coated and the top is nice and smooth.
Place the mold in the fridge for up to 15 minutes or on the counter for 30 minutes until fully solid.
Heat up the chocolate from the bowl again for 20-second increments or until fully melted. Mix in between each time you heat it up.
Scoop the white chocolate into a sandwich bag. Cut a very small hole in the tip of the sandwich bag. Drizzle the white chocolate on top of each cookie.
Sprinkle your red, white, and blue sprinkles on top while the chocolate is still wet. White chocolate hardens quickly so you may need to add the sprinkles after each cookie that gets drizzled with the white chocolate.
