Gift in jar recipes - too much for my brain to handle

[HangingbaublesofBethlehem]

So I had this idea about doing those lovely layered cookie mix in a jar type things - found some beautiful jars in tesco today, glass with a lovely pink lid. Bought jars - but have now come up against something and my head can't sort it.

My jars hold 750ml - all of the recipes I can find on-line are for 1 Quart jars - I have looked it up and this seems to convert to around 1100ml. So I need to somehow convert the recipes down to fit my jars? it's all too much for me, any ideas? I'm sure it's possible but I just feel addled tonight.

roughly a quarter isnt it? will roughly not do it?

like roughly a quarter less? so if recipe says 2 cups of flour, I'd need 1.5 cups? possibly..

Sorry I'm half asleep here, no idea why I get these strange ideas in my head just before bedtime! will tackle it again in the morning when I'm less addled.

extra choc chips sounds good.

Multiply the mix by 2 and you will have the right amount for 3 jars

yes cup measure are cool, will have a bit of an experiment with my jar in the morn. thanks.

good luck
send any spares my way
