420g of sugar???

[BoatsAgainstTheCurrent]

Making this cake & as it's an American recipe I've used a guide to convert 2 cups of granulated sugar to grams (was this one allrecipes.com/howto/cup-to-gram-conversions/). It has come out as 420g! Isn't that a lot? The sugar is for the two chocolate cakes... I usually use 200-odd grams for a two tiered cake... so it's double that and more. Will it be too sweet & should I reduce it?
TIA.

Ive made couple of cakes from American recipes , they always seem to be heavy on the sugar ( but lower fat )
Can you just use a cup to measure ? I think they measure in volume , not weight

I use a one of Nigella's recipes for brownies and that uses 500g of sugar so your 420g might be right...

Well 1 cup is 250 ml which is 250 grams. So actually your 2 cups of sugar should be 500g.

Ive not looked at the recip but it depends on serving and raising agents. American cakes can be heavy on the sugar.

Have a small slice it will be fine

american recipes seem v heavy on sugar
i have a similar amount for a brownie recipe - tastes nice tho

I use half or less than half of stated sugar in baking and there are never any complaints from the kids. Today I baked a cake and used a sugar substitute. Kids happy with cake didn't notice any difference.

Lots of sugar , as in brownie recipes, make the cake more dense and fudgy, (as well as very sweet, of course). Should be scrummy fine but it won't be like a chocolate sponge
