Use Dark corn syrup for light

1 cup for every cup of corn syrup

Yes, in either direction, cup for cup. Dark corn syrup is corn syrup with refiners' syrup, a type of molasses, and caramel color, so it adds a deeper color and a mild molasses taste; light corn syrup is nearly clear and flavored with vanilla. To stand in for dark, mix ¾ cup light corn syrup with ¼ cup molasses per cup. Keep dark syrup out of marshmallows, white frosting and clear candy.

What changes4 options

Dark corn syrup for light

a mild molasses, toffee note

The two cook and set the same way. Dark syrup carries a mild molasses flavor and a brown color into whatever it goes into.

Best for
pecan pie, caramel corn, gingerbread and spice cookies, barbecue sauce and glazes, fudge and chocolate candy
Suits
vegan
Where it fails
Marshmallows, white or pastel frosting, fondant, clear hard candy and lollipops, where the color and flavor show. In caramel it hides the color you would use to judge doneness, so go by a thermometer.

Light corn syrup + molasses for dark

very close to dark corn syrup

The closest match when a recipe calls for dark corn syrup and only the clear bottle is in the cupboard. The molasses puts back the color and flavor.

Best for
pecan pie, gingerbread and baked beans, glazes for ham
Prep
Stir the two together before measuring into the recipe. Use regular unsulphured molasses, not blackstrap.
Suits
vegan
Where it fails
Blackstrap molasses is bitter and makes the mix harsh.

Light corn syrup for dark

sweeter-tasting and plainer, with no molasses note

A plain swap with no molasses added. The recipe sets and cooks the same and comes out paler and milder.

Best for
pecan pie, for a lighter, more vanilla-flavored filling, candy and caramel, any recipe where dark syrup is a small amount
Suits
vegan
Where it fails
Recipes that rely on dark syrup for flavor and color, such as shoofly-style pies and dark glazes, taste flat.

Golden syrup for either

light butterscotch

A thick amber syrup that sits between the two in color and flavor. It cooks like corn syrup, including in candy.

Best for
pecan pie, caramels and toffee, flapjacks and bars
Suits
vegan
Where it fails
White frosting and marshmallows, where its amber color shows.

Tips for substituting corn syrup

4 tips
  1. Pecan pie: either syrup works at the same amount. Dark gives a deeper, more toffee-like filling and light gives a sweeter, more vanilla one. Half of each is common.
  2. Smaller measures of the stand-in for dark: ½ cup = 6 tbsp light corn syrup + 2 tbsp molasses. ¼ cup = 3 tbsp light corn syrup + 1 tbsp molasses.
  3. Candy: both syrups cook to the same temperatures. With dark syrup you cannot judge a caramel by its color, so use a thermometer.
  4. For anything meant to be white or clear, such as marshmallows, royal icing, fondant or lollipops, wait until you have light corn syrup or use glucose syrup.

Questions

4 questions

Can light corn syrup be substituted for dark?

Yes, cup for cup. The recipe cooks and sets the same; it comes out lighter in color and without the molasses note. To get closer to dark corn syrup, use ¾ cup of light corn syrup plus ¼ cup of molasses for each cup.

Can I use dark corn syrup instead of light in pecan pie?

Yes, at the same amount. Many pecan pie recipes call for dark corn syrup in the first place. The filling sets the same and has a deeper color and a toffee, molasses flavor.

Can I use dark corn syrup instead of light in candy, marshmallows or frosting?

It works the same way in the pot, so it is fine in caramels, fudge, brittle and caramel corn. Avoid it in marshmallows, white frosting, fondant and clear hard candy: it turns them tan and gives them a molasses taste.

Is dark corn syrup the same as molasses?

No. Dark corn syrup is corn syrup with a small amount of refiners' syrup, a type of molasses, added for color and flavor. It is much milder and less bitter than molasses, and the two are not interchangeable cup for cup.
