In a pot set over medium heat, bring maple syrup to a boil and let cook 3-4 minutes. Remove from heat.
In another pot set over medium-low heat, heat 1 cup of Dairyland cream. Remove from heat.
Using a whisk, stir the syrup into the hot cream. Set aside.
In a bowl, combine the cornstarch with the remaining cream. Stir until mixture thickens, making sure to break down any clumps. Add this mixture to the maple syrup mixture and reheat over medium-low heat, stirring constantly until mixture thickens. Remove from heat.
Add the butter and whisky. Stir and serve with a selection of dipping items (sponge cake, donuts, pretzels, cheese, fruit, etc.).
