In Louisiana, we make chocolate eclairs with chocolate flavored filling.
And shortly pre-pandemic, I had stumbled on an asian-owned bakery that filled theirs with whatever you wanted, because they didn’t fill them until they were ordered. Kinda nifty, IMHO.
That's genius. A cafe here sells donuts and you pick your flavour.
It turns up in a syringe type thing and you can inject your donut yourself.
Bit of a gimmick but they don't taste half bad either and it's a nice cafe as well.
Would eat all of these.
