Preheat Oven: Begin by preheating your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease each cup lightly.
Mix Wet Ingredients: In a large mixing bowl, combine the pure pumpkin puree, granulated sugar, brown sugar, and vegetable oil. Whisk together until smooth.
Add Eggs & Vanilla: Crack the eggs into the mixture, add the vanilla extract, and whisk again until fully incorporated.
Combine Dry Ingredients: In a separate bowl, sift together the all-purpose flour, baking soda, baking powder, pumpkin pie spice, and salt.
Combine Mixtures: Gradually fold the dry ingredients into the wet ingredients using a spatula or wooden spoon, mixing just until no flour clumps remain. Be careful not to overmix.
Add Chocolate Chips: Gently fold in the chocolate chips until evenly distributed throughout the batter.
Fill Muffin Cups: Evenly distribute the batter into the prepared muffin tin, filling each cup about 0.67 full.
Bake: Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Once baked, remove the muffins from the oven and allow them to cool in the tin for about 5 minutes. Then, transfer the muffins to a wire rack to cool completely.
Serve & Enjoy: These muffins can be enjoyed warm, or stored in an airtight container at room temperature for up to 3 days. They also freeze well!
