Toll House Chocolate Chunk cookies try this recipe and see if you don't have better results.
Please note - Generally speaking only cakes are baked until a toothpick comes out dry - not cookies. Unless of course, the recipe specifically says otherwise.
This recipe suggests 20 to 25 minutes. Set your timer for 10 minutes. Now you are going to switch the pans around by exchange places and reversing them.
In other words, take out a pan grab it at the back end with the other hand - one movement.
With the now free hand take out the other sheet and put the first pan you took out onto the shelf where the 2nd pan was. That first pan is now on a different shelf and the end that was at the back is now in the front.
With your now free hand grab the 2nd pan by the end that was originally at the back of the oven and put in on the shelf that had held the 1st pan.
Set your timer for 8 minutes - peek at the cookies. If they are starting to brown around the edges and "look" dry in their centers, remove them or give them another minute or so. It rather depends on how big they are. I would have to say never more than another 5 minutes or they will be too dry and hard.
Holding the dough over night in the fridge is fine but certainly not until you've added the chips (or chunks, whichever you use).
I linked that recipe as it was the first I pulled up without having to run to the pantry to find a bag of chips. I usually use the recipe on the bag of chocolate chips itself as I don't care for "chunks".
