Preheat your oven to 400°F (204°C). Grab a 12-slot muffin baking pan and place 12 muffin paper liners in each slot.
Once all dry ingredients are ready (flour, sugars, protein powder, baking soda, salt, and spices), whisk them together in a medium sized bowl. Set it aside.
Once all wet ingredients are ready (eggs, pumpkin, oil, and vanilla), whisk them together in another bowl. Make sure everything is blended nicely.
Create a hole in the center of the dry ingredients bowl and pour the wet mixture in. Use the whisk or an electric mixer to blend everything together. Your completed batter is now ready to be poured in each of the 12 slots.
Distribute the batter inside the muffin liners in your pan. You may use a spoon or ice cream scoop if you find it difficult to pour the batter from the bowl.
Bake the muffins in the oven for 18-22 minutes. Use the toothpick test to determine when the muffins are ready, if needed.
Take the pan out when the muffins are ready and let the muffins cool before serving.
