First, gently place your Oreo or favorite sandwich-style cookies into the fridge for about an hour. This step helps them firm up, making them perfect for dipping!
While your cookies are chilling, get your sprinkles ready by pouring them into a small bowl (or separate bowls if you're using a few different colors).
Line a baking sheet with parchment paper and set it aside; this will be the resting spot for your beautifully decorated cookies.
Carefully melt your dairy-free white chocolate. You can do this in short bursts in the microwave, stirring well after each interval, or gently over a double boiler until it's wonderfully smooth and creamy.
Now for the fun part! Take one chilled cookie, dip it completely into the melted white chocolate, letting any extra chocolate drip off for a clean finish.
Immediately after dipping, roll or gently sprinkle your cookie with the colorful sprinkles. Then, carefully place it onto your prepared baking sheet.
Continue this process with all your cookies. Once they're all dipped and decorated, transfer the baking sheet back into the fridge for about 30 minutes until the chocolate has fully set and is firm to the touch.
Once set, your delightful, homemade Valentine's treats are ready to enjoy or gift!
