Lightly spray 18 standard-size muffins cups with cooking spray. In a large bowl, combine all batter ingredients. Place about 1 tablespoon of the batter into each muffin cup. In a small bowl, combine the cinnamon and sugar. Divide and sprinkle the cinnamon sugar mixture over each of the muffins. Arrange the SPAM® with Bacon over the batter (about 1 tablespoon in each muffin cup). In another bowl, combine the 3 eggs and 2 tablespoons of milk. Divide and pour the egg mixture over the batter (about 1 tablespoon in each muffin cup). Drizzle the muffins with syrup. Place muffin pans in a cold oven and set temperature to 350°F. Bake for 15-20 minutes or until the egg mixture is set. Let muffins stand for 5 minutes in the cups. Remove muffins from cups and serve warm or at room temperature. If desired, serve with additional maple syrup for dipping. Makes 18 muffins.
