By hand.....At least make the base.
Here's a bowl, a whisk, and several eggs. Sugar's over there. Hazelnuts are over there. Flour is right here. There's the butter. Get cooking.
No mixer! Whisk by hand!
Sacrilege I tell you. Power tools were created to use, not look pretty. My kitchenaid mixer is my most prized kitchen gadget.
okay sounds easy enough!!!

I actually haven’t even made one in I don’t even know how long though hahah
I can tell you exactly when you made your last attempt at omelettes. Way back last year
