handwriting in my son's Year 1 class varies hugely, from nearly perfect "pre-cursive" to barely legible characters, so I wouldn't worry about that at all.
his class teacher has said to us not to worry about trying to do the teacher role, it's difficult for the kids to move between our mum role and a sudden teacher one hence they mess about and won't engage. DS is EXACTLY as you describe, and he generally loves school.
the head teacher has said to fit in a few lessons each day to keep the formal learning habit intact, and then add in a bit of fun learning, which might be related to the formal stuff, or it might not. so making biscuits would involve recognising numbers and following instructions, or reading their favourite books you could look for particular letters or words, or a treasure hunt outside (when it's not sleeting!) to do nature stuff and physical exercise.
That last thing - exercise - really helps with DS, and we fit Joe Wicks or KidzBop or Kids Cosmic Yoga (all of which they do at school) between learning tasks, apparently at that age they have 20 mins attention span max, so breaking the morning up is essential or they just can't stay focussed.
I am no yummy-mummy with hours to spend schooling or crafting, I work full-time and so our days are all of the above squashed together, some days it works and some days it just doesn't...and then there is Kiri and Lou on repeat on the TV to learn about emotional relationships.
try not to be too hard on yourself or your DD, just do what you can and that'll be good enough
