1 14ouncecan sweetened condensed milk
¼cupespresso or strong coffeeoptional
2tablespoonsbutter
1teaspoonhigh quality vanilla extract
Instructions
Melt all ingredients together in a double boiler, stirring occasionally.
If you have a microwave you can probably get away with melting this on low heat if you keep an eye on it. The sauce can be refrigerated after melting, and reheated with a little water, milk or more espresso if you like.
