MG: Sorry I missed your question -
The soda doesn't go flat - sounds like
an overmix problem. I always test bake
one cookie. If it's runny It gets
a little more flour or Oatmeal.
You will get a much better cookie if you refrigerate the dough. After cooling roll your dough into a long roll - if sticky
add flour. Cut it in half and keep deviding so you have 24 or 48. They
are then uniform. Remember never grease or oil a cookie sheet if they contain a large amount of shortening. (like choc chip)
But you will need it for Oatmeal.
If she likes to bake, get her a High Temp flexible cookie Pad for Christmas.
I have six - lay them on the cookie sheet and bake on them. Cookies pop off
easy. I put one under pies or anything
I bake and they catch all the spills -no
more cleaning bottom of oven or baking
sheet. A double insulated cookie sheet is good but adding the baking pad is
the cats meow. A great Christmas gift about
$24 each. Invented in the UK they are
cheaper there.
