Spiced Dulce de Leche

Place butter, sugar, instant coffee, and cinnamon in a nonstick saucepan over low heat. Stir until sugar dissolves and mixture becomes homogeneous.

Increase heat to medium and add condensed milk. Bring to a gentle boil, stirring constantly. Let boil for a couple of minutes until thickened. Pour into containers. Sealed, this will keep in the refrigerator for 2 weeks.
