Notes

*Using old fashioned oats will make your muffins overall lighter and slightly fluffier, but you'll have more of a chewy texture from the oats. They're more... noticeable... in every bite. That's not a bad thing, just worth noting!

Using instant oats will make your oatmeal muffins a bit denser (the oats in general will make them more dense than your typical muffin) but I found that, if I had to choose, I preferred the finer texture that resulted from using instant oats.
