Prep Your Muffin Pan
Preheat your oven to 350°F (177°C). Line a 12-cup muffin tin with paper liners or grease lightly with nonstick spray.
Mix the Wet Ingredients
In a large bowl, whisk together pumpkin purée, eggs, brown sugar, granulated sugar, melted butter, and vanilla extract until smooth and well combined. The batter should look glossy and thick, with that signature pumpkin color.
Combine Dry Ingredients
Add flour, baking powder, baking soda, salt, and pumpkin pie spice directly to the bowl with the wet ingredients. Gently fold until just combined — don’t overmix or your muffins might turn dense.
If you’re adding chocolate chips or nuts, fold them in now.
Fill and Bake
Divide the batter evenly among the muffin cups, filling each about ¾ full.
Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
Cool and Enjoy
Let the muffins cool in the pan for 5 minutes, then transfer them to a rack to cool completely.
Try not to eat them all warm out of the oven — but honestly, no judgment if you do.
