Make the Ganache Icing:
- In a small saucepan over low heat, melt the butter.
- Add cocoa powder and stir until combined.
- Stir in powdered sugar, vanilla extract, and milk. Mix constantly until the mixture becomes glossy, smooth, and pourable.
- Fold in the pecan pieces.
- Pour the warm ganache evenly over the cake, letting it drip down the sides.
Serve and Enjoy:
This cake is best served warm with a scoop of vanilla ice cream. If serving later, simply reheat individual slices in the microwave for 15–20 seconds to restore that gooey, melty texture. Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
Pro Tip: For an even more intense chocolate experience, drizzle additional melted chocolate or add chocolate shavings over the ganache just before serving.
