I remember as a child eating this toast at my sister’s house. I have been after her for years to give me the recipe which she finally found!
Melt 1/2 stick butter, 1 tablespoon of cocoa, and 2 and 1/2 tablespoons of sugar together. Boil for a minute until it has reduced a little bit.
Spread on your bread and then place bread under the broiler until edges have browned.
My kids got their first taste of this yesterday and they were in heaven!
