Step 1

Warm milk in microwave or on stovetop - just 20-30 seconds to be warm to the touch (cocoa powder will mix in to warm milk much better than cold milk.)

Step 2

Add milk to slow cooker, turn slow cooker on to high.

Step 3

Add in sugar, vanilla, chocolate, and cocoa powder, whisking vigorously after each addition to incorporate. Whisk in cream last.

Step 4

Place lid on slow cooker and set to low, let cook 3-4 hours. Stir occasionally.

Step 5

When chocolate has melted and hot chocolate has thickened, it is ready to serve!

Step 6

Top with mini marshmallows, sprinkles, whipped cream, and even chocolate sauce!
