Chop your semi-sweet chocolate into small, uniform pieces and add them in the last 30 minutes of cooking to prevent scorching and ensure a silky, smooth texture throughout.

Start with 1/2 teaspoon of peppermint extract and taste-test before adding more, as extract intensifies during slow cooking and can quickly become overpowering.

Combine your unsweetened cocoa powder with a small amount of warm milk to create a smooth paste before adding to the crock pot, preventing lumps and ensuring even chocolate distribution.

Reserve your crushed candy canes for garnishing just before serving rather than adding them during cooking, preserving their vibrant flavor and satisfying crunch for maximum impact.

Use whole milk at room temperature rather than cold milk to reduce cooking time and prevent the hot chocolate from developing a skin on top during the slow-cook process.
