A rich chocolaty hot fudge sauce that pours smooth and silky over ice cream. This easy chocolate sauce is the best ice cream topping, and makes the perfect ice cream dessert – a decadent hot fudge sundae.
Melt butter in sauce pan over low heat. Place chocolate squares on butter so they melts together. Add evaporated milk and corn syrup. Stir to combine. Add sugar and salt and stir to blend.
Turn heat to medium and stir constantly until mixture comes to a rolling boil. Boil one minute, until soft ball stage (see notes), then remove sauce from heat.
Add 1 teaspoon vanilla and stir. Serve warm over ice cream. Store in covered container in refrigerator up to one month.
Notes
Put a small spoon full of sauce in a cup of ice water. Try to pick up the sauce from the ice cubes. If you can collect it into a very soft ball, it's the right consistency.This sauce becomes slightly caramel-like when it hits the cold ice cream. For a softer, thinner sauce, pour in 1-2 extra tablespoons evaporated milk.
