This tasted good, but I made the following changes, used 1 cup of whole wheat pastry flour, 1 tsp of pumpkin pie spices, omitted orange zest (do not like orange and chocolate together), only had quick oats on hand. Almost missed the water because it was mentioned in the instruction only. Muffins are faster to bake and are good portion control, made (12) 1/4 cup size muffin tin, and then pour the rest into a 2 cup size Pyrex, baked the muffins for 25 mins. and the Pyrex one 30 mins. I miss the butter flavor, next time I might try using 4 TBS melted butter instead of oil.
I made this recipe into 16 medium size muffins. The oatmeal gives it great texture and flavor. It was just the right amount of chocolate chips. I added 1t vanilla and also sprinkled some coarse sugar on top. I baked the muffins for 20min at 350.
