Blend cocoa and sugar in a big bowl. Add milk and stick butter. DON'T STIR!

Microwave on high for 2 min. Remove from microwave and stir well! This part is tiring.

Add vanilla and if desired some peanut butter! I love to add a big scoop of chunky. Continue to stir til very well blended.

Pour onto a large cookie plate, spread and place in freezer for 20 min or refrigerator for an hour.

Cut and serve!
