Preheat your oven to 375°F (190°C) and generously grease an 8x8 inch baking dish with avocado oil or your choice of neutral oil.

In a medium-sized mixing bowl, combine 2 cups of rolled oats, 2 teaspoons of pumpkin spice, 1 teaspoon of baking powder, and ¼ teaspoon of salt. Stir to evenly distribute.

In another bowl, mix together 1 cup of canned pumpkin puree, 1 cup of milk, 2 large eggs, 2 teaspoons of vanilla extract, and ⅓ cup of maple syrup or honey. Whisk until smooth.

Pour the wet mixture into the bowl with your dry ingredients. Stir gently to combine until no dry oats remain visible.

Carefully pour the combined oatmeal mixture into the prepared baking dish, spreading it evenly with a spatula.

Place the baking dish into the preheated oven and bake for 30-35 minutes, until edges are puffed and golden.

Once baked, remove from the oven and allow to cool for about 10 minutes before slicing.
