Line a cookie sheet with parchment paper. This step ensures easy cleanup after you’ve created your masterpieces.
Twist the 6 Oreo cookies apart gently, separating the cream-filled halves and setting aside the cream on one side.
Cut the 3 pieces of Pillsbury Big Deluxe Chocolate Chip Cookie Dough into 6 equal pieces. Sandwich one piece of cookie dough between each set of Oreo halves, pressing them together gently to stick.
Melt the 1 cup of semi-sweet mini chocolate chips and 1 tsp of coconut oil in the microwave. Start with 30 seconds, then stir and continue to heat in 15-second intervals until fully melted and smooth.
Dunk each Oreo sandwich into the melted chocolate, coating them thoroughly before placing them on the prepared cookie sheet.
Top with 2 tbsp of rainbow sprinkles while the chocolate is still warm so they adhere well.
Let them sit at room temperature or refrigerate for about 15-20 minutes, or until the chocolate hardens.
