Combine the heavy cream, milk, and sweetened condensed milk in a medium saucepan.

Place the saucepan over medium heat and whisk gently for about 5 minutes until the mixture is warmed through, but do not let it boil.

Remove the pan from heat and stir in the amaretto liqueur and vanilla extract until fully incorporated.

Taste the creamer and adjust sweetness by adding more sweetened condensed milk if desired.

Let the creamer cool in the saucepan for about 5 minutes to allow it to thicken slightly.

Using a funnel, pour the cooled creamer into a storage container.

Seal the container and refrigerate the creamer for at least 1 hour before use; it will keep for up to one week.

Shake or stir the creamer well before adding it to your coffee and enjoy.
