Leftover Oatmeal Muffins-2

Leftover Oatmeal Muffins

We make oatmeal all the time and there is often a little bit leftover. I hate to throw away that extra oatmeal at the bottom of the pot, but when it gets cold and clumpy, it is not all that enjoyable to eat. So, in an effort to utilize the leftovers, I threw together this recipe for muffins. I was blown away by how good they tasted! Now, I will make sure that there is always a bit of leftover oatmeal so that these muffins can be made again and again.

I was expecting that leftover oatmeal might make these dense and heavy, but that is not the case at all with these muffins! Instead, they are light and fluffy, but still, much heartier than a cupcake. Spread a little butter on the muffin and drink with a cup of coffee for a nice breakfast.

This recipe will work great with steel cut oats or quick oats. It doesn’t matter, and the recipe quantity is the same, regardless of the type of leftover oatmeal being used.

I added some cinnamon and raisins, simply because that is my favorite topping for my morning bowl of oatmeal. Next time, I may add some diced apple, blueberries, nuts or even chocolate chips. There are so many options!
