In a large mixing bowl of an electric mixer fitted with a whisk attachment, whip the heavy cream on high for 4-5 minutes or until the cream forms tall, stiff peaks.
2 cups heavy whipping cream
When the heavy cream is fully whipped, fold in the condensed milk and vanilla extract. Mix lightly for about 1 minute or until fully combined. The mixture will be thick.
14 ounces sweetened condensed milk, 1 teaspoon vanilla extract
Add in the maple syrup and walnuts. Mix with a rubber spatula, scraping down the sides of the bowl, until the ingredients are well blended.
1 cup pure maple syrup, 1 1/2 cups chopped walnuts
Pour the ice cream into a 9x5-inch loaf pan, cover, and place in the freezer for at least 6 hours or overnight.
When the chill time is complete, remove from the freezer and serve in a waffle cone or bowl.
Garnish with whipped cream, extra chopped walnuts and/or maraschino cherries.
