For the Popcorn:

1. Pop the Popcorn:
   • Pop the popcorn kernels using your preferred method (air-popper, stovetop, or microwave). Once popped, set aside in a large mixing bowl. Make sure to remove any unpopped kernels before using the popcorn.
2. Make the Caramel Sauce:
   • In a medium saucepan over medium heat, melt the butter. Stir in the brown sugar, corn syrup, and salt. Bring the mixture to a boil while stirring constantly. Once it begins to boil, stop stirring and let it cook for 4-5 minutes without stirring, allowing the caramel to thicken slightly.
3. Add Vanilla and Baking Soda:
   • Remove the caramel from the heat and stir in the vanilla extract and baking soda. The mixture will bubble up, which is normal.
4. Coat the Popcorn:
   • Immediately pour the caramel over the popped popcorn. Use a spatula or spoon to gently toss the popcorn to coat it evenly with the caramel. Be careful as the caramel will be hot!
5. Form the Cake:
   • Grease or line a 9-inch round cake pan with parchment paper, and then pour the caramel-coated popcorn into the pan, pressing it down gently to form a “cake” shape. You can also shape it into a heart shape on a large plate for a more festive look, if preferred.
6. Let It Cool:
   • Allow the popcorn cake to cool and set for at least 1 hour. As it cools, the caramel will harden, creating a crispy, crunchy texture.

For the Decorations:

1. Melt the White Chocolate:
   • In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring after each interval until smooth.
2. Decorate the Cake:
   • Drizzle the melted white chocolate over the caramel popcorn cake using a spoon or piping bag. Be creative with your drizzle design!
   • Sprinkle the red and pink sprinkles, mini chocolate chips, and any Valentine’s Day candy you like over the top while the chocolate is still soft.
3. Chill to Set:
   • Place the decorated cake in the refrigerator for about 15 minutes to allow the chocolate to set completely.
4. Serve:
   • Once the chocolate has hardened, your Valentine’s Day Caramel Popcorn Cake is ready to serve! Slice it like a traditional cake or break it into pieces to share.
