No malt I can think of is even close to honey malt. It's actually kind of gross. I bought a 25kg sack of it quite some time ago because, at the time, I thought that with a name like honey malt it should be good. I was wrong. I still have quite a bit left, even though I've been trying to give it away for the past two years. A little goes a very long way.
I'll describe it. Hopefully that will help you to find something equivalent.
Aroma: Almost sickeningly sweet. It reminds me of pig starter - a feed used to fatten up weanlings. It almost smells rancid, sort of like rotten fruit. There is a strong caramel malt aroma, but it's not clean. It has a definite, but low, pig barn aspect. It's very, very aromatic.
Flavour: Follows the aroma for the most part. The rotten fruit (berries most strongly, apples to a degree) is quite strong. No caramel at all, with an extremely low biscuit-like dryness/toastiness. Colour is very light, lighter than vienna malt.
Overally impression: Use it in small amounts, definitely less than ~3%, to give your beer a hard to identify fruity nose/flavour. In high amounts, it's really gross. Undrinkable. Consider yourself lucky you can't get it.
I honestly can't think of any malt that would be similar to this one. It's just so unique.
