Spoon the dulce de leche into a bowl, then beat in the coffee, vanilla and brandy until smooth. Stir in both pots of cream until well mixed.
Pour into 1 large or several smaller sterilised bottles. This will keep in the fridge for 2 weeks. Drink in liqueur glasses or serve over ice.
Sara says...If you like Baileys, you are going to love this! I usually make it with condensed milk but had a flash of inspiration when I saw a jar of dulce de leche, the soft spoonable toffee often used to make banoffee pie, in the supermarket. If you want to make a batch to give as gifts, stick a label on the bottles to make sure that the lucky recipient knows to store it in the fridge.
