Mix water and pancake mix as instructed on box. can add extras and mix also. I added mini chocolate chips after I poured it in the pan because I can't have chocolate. I would suggest pressing them down a little if you make different ones.
Make sure to spray the pan first. Bake 8-10 minutes. If you don't have a half-size pan you'll have to mix a full batch called for on the bos and a full batch size mini muffin pan.
