Soak the Dates (3/4 cup) in hot water for at least 20 minutes to soften them. Pit them and set aside.
Preheat oven to 300 degrees F (150 degrees C).
In a high-speed blender or food processor, place in the Almond Milk (1/2 cup), Apple (200 gram), and dates. Blend until smooth paste forms.
Transfer the paste in a mixing bowl and add in the Peanut Butter (1/2 cup) and Ground Cinnamon (1 teaspoon). Using a fork or spatula, combine until everything is well incorporated.
Mix in the Old Fashioned Rolled Oats (3 cup) and stir well.
Transfer the mixture to a lined or greased 8x8-inch baking pan. Using a spatula or the back of a spoon, smooth out the mixture to fit the size of the pan.
Bake it in the oven for 20-30 minutes, or until a toothpick comes out clean.
Let the baked oatmeal cool down before slicing and serving it!
