Brew day mishap - quick Light Malt Extract repalcement?

I’m in the middle of brewing and have about 35 minutes before a late boil extract addition. Of course, my Light Malt Extract syrup spilled on the counter and floor loosing about .4 lbs.

Is there a quick substitute I can add (all I have on hand is Dark Dry Malt Extract) to compensate? If so, how much should I use?

I suppose it’s not the end of the world if I lose a few IBUs…

Thanks!

Just add some sugar.

Thanks for the help. I still undershot my OG by a little, but it’s looking like the batch will turn out to be a nice session beer.
