Here's a knock-off version of Biscoff from "Baked Explorations" of "Baked" fame.
I wanted to like these. I really did. Actually, what I wanted was my own stash of Delta Airlines cookies that did not require begging a stewardess/flight attendant for one more. (This was before I knew you could just buy them in a Big Box Food Store.)
But these aren't an exact duplicate...or at least mine weren't. They weren't as thin, they weren't as crispy and the spice blend was not spot-on.
(I know...I just reread my original post and see where I added almond meal...so how can I claim it's not exactly right? My only defense is research must have shown almond meal in speculaas, so I added it. Now that I think about it, why would an airline waste $$ for almond meal on customers content with flour?)
