Recipe calls for 2 extra large eggs and i have large how many do you use?

If it was me, I would just use 4 large eggs. pick the largest of the large. If you are making a specialty recipe where one minor change might make it bake differently, well, then I guess you might want to just buy xlarge. Honestly, I don't know how much of a difference it will make! :) I ad lib recipes all the time! I am not a professional baker but I bake 'from scratch' frequently! Good luck!
