Ingredients:

  • 2 cups All-Purpose Flour
  • 1/2 cup Light Brown Sugar, packed
  • 1/4 cup Granulated Sugar
  • 1 1/2 teaspoons Baking Powder
  • 1 teaspoon Baking Soda
  • 1/2 teaspoon Fine Sea Salt
  • 1 1/2 teaspoons Ground Cinnamon
  • 1 teaspoon Ground Ginger
  • 1/2 teaspoon Ground Nutmeg
  • 1/4 teaspoon Ground Cloves (optional)
  • 1 cup Canned Pumpkin Purée (not pumpkin pie filling)
  • 1/2 cup Vegetable Oil (or neutral oil)
  • 2 Large Eggs (room temperature)
  • 1 teaspoon Vanilla Extract
  • 1 cup Semi-Sweet or Dark Chocolate Chips (reserve 2 tbsp for topping)

Instructions:

  1. Preparation: Set the oven temperature to 425°F (220°C). Arrange the rack in the middle position and line the 12-cup muffin tin with paper liners or grease thoroughly.
  2. Combine Dry Ingredients: In the first large mixing bowl, whisk together the flour, both sugars, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves. Ensure the spices are evenly distributed.
  3. Combine Wet Ingredients: In the second bowl, whisk the pumpkin purée, oil, eggs, and vanilla extract until the mixture is smooth and fully emulsified.
  4. Gentle Integration: Pour the wet mixture into the dry ingredients bowl. Using a rubber spatula, fold the ingredients together just until they are combined. Stop mixing when you still see a few streaks of flour (a lumpy batter is correct).
  5. Add Chocolate: Gently fold in 90% of the chocolate chips, reserving the rest for the topping. Do not overwork the batter.
  6. Scoop and Fill: Distribute the batter evenly among the 12 muffin cups, filling them about 3/4 to the top for a professional dome. Sprinkle the reserved chocolate chips over the tops.
  7. Initial Bake (The Secret to the Dome): Immediately place the tin in the preheated 425°F (220°C) oven and bake for exactly 5 minutes.
  8. Reduce Heat and Finish: Without opening the oven door, reduce the temperature to 375°F (190°C). Continue baking for an additional 17–20 minutes, or until a toothpick inserted into the center comes out clean.
  9. Cooling: Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
