Oat Flour Muffins With Apple Sauce

Using apple sauce does a couple of things in baking. It adds both moisture and allows for the reduction of fat. When these come out of the oven, if you were to break one open, it would appear to not be fully cooked. Your instinct might be to pop them back in the oven. But please fight this urge. It’s only the apple sauce. Once they are fully cooled, everything gels and you have a normal, fully cooked muffin.

That being said, please note that you should still be able to stick a toothpick into a just-baked muffin and have it pull out clean. If not, then they do indeed need a few more minutes of baking.

Can You Substitute Oatmeal For Flour In Muffins?

According to the Quaker Oats website:

…you may substitute oats for up to one-third the amount of flour called for in the recipe using either Quick or Old Fashioned Oats. Instant Oatmeal is cut too fine, and is not recommended for baking.
