Preheat oven to 350 degrees. Line 12 cup muffin tin with cupcake liners and spray inside of liners with oil.
Melt ghee or butter in microwave and set aside to let cool.
In a medium bowl, whisk together flour, baking soda, cinnamon and salt.
Heat the milk in the microwave for ~30 second to warm it up (this is so that the liquid mixture stays one consistency).
In another bowl, mix the cooled ghee/butter, maple syrup, vanilla, egg and warmed milk.
Once the wet ingredients are well mixed (use a whisk or hand mixer), slowly add in the dry ingredients. Mix until just combined. Fold in 1/2 cup pecans.
Using a ¼ cup or ice cream scoop, spoon batter into prepared liner until about ¾ full. Top with remaining pecans and bake for 20 minutes or until toothpick inserted into middle comes out clean.
