What to add if oatmeal raisin cookie dough to dry?

If your oatmeal raisin cookie dough is too dry, you can add a little milk or water, one tablespoon at a time, until the desired consistency is reached. Alternatively, you could incorporate an extra egg or some melted butter to help moisten the dough. Be careful not to add too much liquid at once, as it can lead to overly wet dough. Mixing in additional oats or raisins can also help balance the texture.
