In a medium saucepan over medium-low heat, add the sweetened condensed milk, chocolate chips, and creamy peanut butter. Stir gently until the mixture starts to melt together, about 1-2 minutes.

Keep stirring until the chocolate is completely melted and the mixture is smooth and glossy, which should take about 4–5 minutes.

Remove the saucepan from heat, then stir in the butter, vanilla extract, and a pinch of salt if using. Mix thoroughly until everything is beautifully combined and creamy.

Drizzle your Peanut Butter Hot Fudge generously over desserts like ice cream, brownies, or pancakes.

If you have any leftovers, allow the fudge to cool, then store it in an airtight jar in the refrigerator for up to 2 weeks.

When you’re ready to indulge again, reheat the fudge gently in the microwave or on the stove, stirring frequently until it becomes smooth and saucy once more.
