Method
Prep and preheat
- Preheat oven to 375°F and line a muffin tin with liners, leaving the cups ready for batter.
Mix dry ingredients
- Whisk all-purpose flour, baking powder, and pumpkin pie spice together until evenly combined and no dry streaks remain.
Make batter
- Beat pumpkin puree, milk, vegetable oil, large eggs, and granulated sugar until smooth, glossy, and fully incorporated.
- Fold the wet mixture into the dry ingredients just until combined, scraping the sides to avoid pockets of flour.
Add first layer of batter
- Divide half the batter among muffin cups, filling each about halfway.
Create cinnamon swirl
- Mix brown sugar, cinnamon, and melted butter into a thick, spreadable mixture.
- Spoon a small amount of the cinnamon mixture into the center of each cup, then swirl it gently into the batter with a spoon to create a marbled pattern.
Top and swirl
- Top with remaining batter, filling the cups to about three-quarters full.
- Swirl again with a toothpick, dragging through the center lightly to keep the ribbon pattern visible.
Bake
- Bake 18-20 minutes until a toothpick comes out clean, with lightly domed tops.
Glaze
- Whisk powdered sugar with milk until smooth and pourable, then drizzle over warm muffins while the tops are still slightly hot.
Notes
Pro tip: swirl gently with a toothpick to create a marbled pattern—overmixing will muddy the ribbons. Store muffins in an airtight container in the fridge for up to 4 days; rewarm briefly in the microwave. Freezer yes: freeze cooled muffins (un-glazed if possible) up to 2 months and thaw overnight, then glaze. For a less-sweet option, use half granulated sugar and reduce glaze milk slightly to keep it thick.
