Place the unsalted softened butter in a mixing bowl.

Use a hand mixer to beat the butter for 3-5 minutes until it becomes light and fluffy.

Scrape down the sides of the bowl using a silicone spatula.

Add the entire can of sweetened condensed milk to the butter and mix for another 2-3 minutes.

Incorporate the Nutella and mix for an additional 1-2 minutes until smooth.

Scrape down the sides and base of the bowl again, then fold the mixture with the spatula to remove air bubbles.

Pipe generous swirls on chocolate cupcakes, frost a layer cake, or use as a filling for cookies.

A dollop on a warm slice of pound cake or biscuits adds special touch to any moment.

Keep covered in an airtight container in the refrigerator for up to 1 week.

Let it come to room temperature before using and whip with a hand mixer if needed.

For longer storage, freeze for up to 3 months.
