I make big batches of oatmeal but always have a little left over. This is a great use for cooked oatmeal. I use coconut oil for better texture and flavor. Here's a great article from Dr. Oz as to its health benefits.
2 eggs
1/2 c coconut oil (or butter)
1 1/2 c leftover cooked oatmeal
1 t vanilla
1/2 c brown sugar
1 t pumpkin pie spice
1 c flour
1 t baking powder
1 t baking soda
In large mixing bowl, beat eggs. Add remaining wet ingredients. Add brown sugar and spice. Add remaining ingredients and stir until just moistened. The batter will seem thick. Spoon mixture into greased loaf pan. Cook at 325 for 60 min or until knife test comes out clean.
