Gather your ingredients. Start by soaking the dates for about 10 minutes so that they are easier to blend.
Preheat the oven to 350°F.
In a high-speed blender, grind the oats into a flour-like consistency, making oat flour. Then, add the pumpkin pie spice, brown sugar, baking powder, baking soda, and sea salt. Blend to combine.
Add the remaining ingredients to the blender. Start by blending on a low setting and gradually work your way up to a higher speed while using the tamper tool to push down the ingredients so that everything is fully incorporated and smooth.
Line the muffin pan lightly with cooking oil. Using a spoon or spatula, fill the muffin pan openings with the batter. Top with pumpkin seeds (pepitas) and rolled oats. Gently press them down.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins rest in the pan for 5 minutes before transferring them onto a wire rack to cool, for about 5 minutes. Enjoy!
