My grandma used to make a waffle cake with chocolate cream filling, Romanian/Hungarian/Russian style.
My mom is trying to recreate it, without success. But she doesn't exactly know how to make the cream.
I had one recipe with sweet cream and chocolate pudding, but it didn't work well — it was too wet.
I had another recipe with cocoa and halva, where you cook them both with some water, butter and sugar, and it too didn't work — also too wet, and too chocolatey.
How can I find a decent recipe for the filling? Are there any names I should be searching for?
