Step 1

Add all the ingredients together in a small saucepan and cook over medium heat.

Step 2

Breakup the chunks of peanut butter and stir well. Keep a close eye on the sauce, so it's not burnt or gets too thick and brown. Scrape down the sauce on the side of the pan to mix it all well.

Step 3

Let the sauce bubble, and it will soon thicken. Turn the heat off, remove it from the pan and let cool slightly before serving. The sauce keeps well in the fridge for up to 7 days.
