Step 1

Preheat the oven to 425 degrees F. Line a 12-cup muffin pan with muffin liners.

Step 2

Whisk to combine the pumpkin puree and eggs in a large bowl. Whisk in the granulated sugar, brown sugar, oil and milk. Sift in the flour, baking powder, baking soda and salt. Fold until just combined.

Step 3

Scoop 1/4 cup of the batter into each muffin cup. Add a scant 1/2 teaspoon of pumpkin spice into each cup and use a toothpick to swirl. Top with a rounded 1 tablespoon of batter and smooth over the top.

Step 4

Bake for 5 minutes, then reduce the heat to 350 degrees F. Bake until a toothpick inserted into the center comes out clean, 15 to 20 minutes. Let cool completely in the pan, about 1 hour, before serving.
