Preheat oven to 350 degrees Fahrenheit.
In a large bowl, mix together all dry ingredients.
Once mixed, add in all the wet ingredients (pumpkin, egg, and oil) and gently combine.
Use a cookie scoop to scoop the mixture into a muffin tin-lined muffin tray. Only fill each muffin tin 3/4 of the way up to allow the muffins to expand.
Tap the tray on the counter to set the batter and then bake for 20-25 minutes at 350 degrees Fahrenheit.
Remove muffins from oven and let cool for 5 minutes before enjoying!
