For an extra layer of richness, add a teaspoon of coconut oil while heating. Adjust the amount of powdered peanut butter to suit your personal preference. Garnish with a sprinkle of cocoa powder or a drizzle of vegan chocolate syrup for a touch of elegance. This recipe can easily be doubled or tripled to serve a crowd. Keep warm on low heat, stirring occasionally. For a more intense chocolate flavor, use dark chocolate chips.
