Step 6. Cool Slightly:
- Let the cake cool in the pan for about 10 minutes, until warm to the touch.
Step 7. Make the Chocolate Drizzle:
- In a medium saucepan, combine sugar, butter, milk, and cocoa powder. Cook over medium heat, stirring constantly.
- Once it comes to a boil, continue stirring for 1–2 minutes until it turns glossy and smooth. Remove from heat and stir in vanilla extract.
Step 8. Drizzle Over Warm Cake:
- Pour the hot chocolate drizzle evenly over the still-warm cake. Let it soak in slightly; it will set into a shiny, fudgy layer as it cools.
Step 9. Optional Toppings:
- Once cooled or just before serving, pipe on your favorite frosting and sprinkle chocolate shavings, cocoa nibs, or mini chocolate chips for extra flair!
Step 10. Serve:
- Enjoy warm for a molten, gooey bite or let it cool fully for a more structured, rich dessert. Either way, it’s heavenly.
