The hot chocolate mix I used is the type that you'd add milk to, rather that one that just requires water. Use your favorite mix - it adds a lot of flavor to the ice cream.
The resulting ice cream is rich and very chocolate-y with the flavor of malt in the background.
I won't tell anyone you cheated.
Hot Chocolate Malt Ice Cream
1 cup hot chocolate mix
1 3.5 ounce package instant chocolate fudge pudding mix
1/2 cup sugar
1/2 teaspoon salt
1/4 cup malted milk powder
2 cups half-and-half
1 tablespoon vanilla extract
Heat the milk - not quite to the boil - and add the hot chocolate mix. Stir to combine.
Meanwhile, combine the instant pudding, sugar, salt, and malted milk powder in a bowl. Stir to combine. Add the half-and-half and vanilla and stir to combine. Add the hot chocolate mixture and stir well.
Cover the mixture and refrigerate until fully chilled.
When the mixture is chilled, churn it in your ice cream maker according to manufacturer's directions.
