Melt the butter in a microwave-safe bowl in the microwave or in a small saucepan on top of the stove. Note the T.O.H recipe insists on only using butter.

If using saucepan remove from the heat.

Add cocoa and mix well. Stir in sugar. Add milk and stir until smooth. Add peanut butter and mix well.

Drop by teaspoonsful onto wax paper.

Flatten tops and shape into 1-inch patties.

Refrigerate until serving.

note mine must be chilled to get the right texture but of course I just may be rushing things along.

Also if it starts to get too thick you can add a bit more milk but do so carefully. It will cause problems with it setting up right. I would add by 1/8 teaspoons Stir see if it helps if not then add the next 1/8 [like adding liquid to baking mixtures] It will also help a child understand about adding.
