Start by preheating your oven to 350°F (175°C).
Then, line a muffin tin with paper liners and give them a quick spritz of nonstick spray to ensure your muffins release easily.
In a large mixing bowl, whisk together the wet ingredients - pumpkin puree, melted coconut oil, eggs, maple syrup, and vanilla extract.
In a separate bowl, whisk together the dry ingredients - oat flour, baking powder, baking soda, salt, and the warm, comforting pumpkin pie spice.
Now, it's time to marry the wet and dry ingredients. Pour the dry mixture into the bowl with the wet ingredients and stir until everything is beautifully combined.
Gently fold in the dark chocolate chips and chopped pecans.
Using a scoop or spoon, portion the muffin batter into your prepared muffin tin, filling each cup about three-quarters full.
Bake them in the preheated oven for approximately 20 minutes or until a toothpick inserted in the center comes out clean.
Once your muffins have achieved golden perfection remove them from the oven and let them cool in the muffin tin for a few minutes. Then, transfer them to a wire rack to cool completely.
