Heat the oven to 350°F. Spray a muffin pan with cooking spray or put paper baking cups inside.
In a big bowl, add the flour, sugar, pumpkin pie spice, baking soda, baking powder, and salt then mix together.
In a smaller bowl, crack the eggs. Add the pumpkin puree, vanilla extract, and avocado oil. Whisk until smooth.
Stir in the chocolate chips.
Pour the wet mixture into the big bowl with the dry ingredients. Use a spatula to gently fold it together. Don’t stir too much and stop when you don’t see dry flour anymore.
Scoop the batter evenly into the muffin cups.
Bake for 20–25 minutes until a toothpick stuck in the middle comes out clean.
Let the muffins cool on a rack then eat and enjoy!
