Prepare the Oven and Muffin Tin
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or grease each cup lightly if not using liners.
Mix Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, baking soda, baking powder, salt, cinnamon, nutmeg, and cloves until well combined.
Combine Wet Ingredients
In a separate bowl, mix the pumpkin purée, oil (or melted butter), eggs, and vanilla extract until smooth.
Bring the Batter Together
Pour the wet ingredients into the bowl with the dry ingredients. Gently fold until just combined, being careful not to overmix, as this can make the muffins dense.
Add the Chocolate Chips
Fold in the chocolate chips, ensuring they’re evenly distributed throughout the batter.
Fill the Muffin Cups
Divide the batter evenly among the muffin cups, filling each about ¾ full.
Bake the Muffins
Bake for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
Cool and Serve
Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely. Enjoy warm or at room temperature!
