Pre-heat oven to 425 degrees F and line a standard 12 cup non stick muffin tin with cupcake liners.
In a large bowl, whisk together pumpkin, sugar, butter, egg, and vanilla until smooth.
Add in flour, cocoa powder, baking soda, baking powder, pumpkin pie spice, and salt. Use a rubber spatula to mix, being careful to not over mix.
Gently stir in 3/4 cup chocolate chips.
Scoop evenly into prepared muffin tin. You should get 12 muffins.
Top with remaining 1/4 cup chocolate chips and (optional) sprinkle with turbinado sugar.
Bake for 5 minutes at 425 degrees F, then lower heat to 350 degrees F (keep muffins in oven).
Bake an additional 12-14 minutes, or until a toothpick comes out *almost* clean. **Don’t over bake and make sure you’re not sticking a toothpick into a chocolate chip**
