In a microwave-safe bowl, combine the white chocolate chips and coconut oil. Heat in the microwave in 20-second intervals, stirring in between, until fully melted and smooth. Take care not to overheat, as chocolate can scorch easily.
Once the chocolate and oil mixture is smooth, stir in the cake batter extract. This step is crucial for infusing that iconic birthday cake flavor into your magic shell.
Gently fold in the rainbow sprinkles. This adds texture and color to your magic shell, making it visually appealing and fun!
Let the mixture cool for a few minutes before using it. If it becomes too thick, you can reheat it gently in the microwave for a few seconds.
Drizzle the magic shell over your favorite ice cream. Watch it harden instantly into a crunchy shell. Enjoy immediately or store any leftovers!
