Instructions

• Measure all ingredients: 1/2 cup sweetened condensed milk, 1/2 cup creamy peanut butter (do not use natural peanut butter), 5 tablespoons water, and 1 teaspoon vanilla extract.
• Place the sweetened condensed milk and peanut butter in a small saucepan.
• Heat the mixture over low heat, stirring constantly, until the peanut butter and condensed milk are smooth and fully combined (about 1–2 minutes).
• Add the 5 tablespoons water and continue stirring until the water is fully incorporated and the sauce is smooth.
• Remove the saucepan from the heat and stir in the 1 teaspoon vanilla extract until evenly mixed.
• Transfer the sauce to a jar or airtight container and let it cool to room temperature; the sauce will thicken as it cools.
• To serve, heat the desired amount in the microwave for a few seconds, stir until pourable, and drizzle over ice cream.
• Store the cooled sauce covered at room temperature.
