In a large saucepan on the stove, bring the milk to a boil. As soon as it begins to boil, add the oats and reduce to a simmer.
Simmer the oats for 5 minutes or until cooked. Stir in the applesauce and spices.
Crack the eggs into the oats over medium-low heat and quickly whisk for about 1 minute until cooked. If you stop stirring before the egg is cooked, you'll have clumps of egg white in your oatmeal; continually stirring will distribute the egg evenly for the creamy, custardy texture.
Stir in the blueberries and let cook on low for one minutes. Remove from heat and serve immediately.
Add any desired toppings, such as brown sugar, nuts, bananas, or other fruit.
Notes
This recipe can be easily halved or doubled, just adjust the ingredients proportionally. The cooking time will remain the same. If using frozen blueberries, rinse with warm water and let sit beforehand to defrost.
