1-First Step: Prep and mise en place Preheat your oven to 375°F (190°C). Line a 12-count muffin tin with liners or lightly grease it. If making minis, use mini liners and expect to double the yield. Measure all ingredients precisely and set them out: flours, baking powder, spices, salt, brown sugar, egg, vanilla, pumpkin puree, milk, and melted butter. For the cinnamon-sugar coating, combine granulated sugar and ground cinnamon in a shallow bowl. Melt 1/4 cup (56g) unsalted butter and set aside for rolling.

2-Second Step: Mix dry ingredients In a medium bowl, whisk together 1 and 3/4 cups (220g) whole wheat or all-purpose flour, 1 and 1/2 teaspoons baking powder, 1 and 1/2 teaspoons pumpkin pie spice, 1 teaspoon ground cinnamon, and 1/2 teaspoon salt. Whisking helps distribute the leavening and spices evenly so every bite tastes balanced.

3-Third Step: Combine wet ingredients In a large bowl, whisk 1/4 cup (56g) melted unsalted butter with 1/2 cup (100g) packed light or dark brown sugar until glossy. Add 1 large room-temperature egg and beat lightly until combined. Stir in 1 and 1/2 teaspoons pure vanilla extract, 3/4 cup (170g) pumpkin puree, and 1/2 cup (120ml) milk. The batter will be thick but pourable.

4-Fourth Step: Fold wet and dry together Make a well in the dry ingredients and pour in the wet mixture. Fold gently with a spatula until just combined; a few small streaks of flour are okay. Overmixing develops gluten and makes muffins tough, so stop once the batter is homogenous and slightly lumpy.

5-Fifth Step: Portion into the pan Use a cookie scoop or two spoons to fill each muffin cup. For standard muffins, fill cups about 3/4 full. For mini muffins, fill cups about 3/4 full as well. The batter should make roughly 12-16 standard muffins or 36-48 minis depending on how full you fill the cups.

6-Sixth Step: Bake and test for doneness Bake at 375°F (190°C). Standard muffins will take 20-25 minutes; minis will take 10-12 minutes. Rotate the pan halfway through if your oven has hot spots. Test doneness by inserting a toothpick into the center; it should come out mostly clean with a few moist crumbs, not wet batter.

7-Final Step: Cinnamon-sugar coating and cooling Let the muffins cool in the pan for 5 minutes, then transfer to a wire rack until they are warm but not piping hot. For the coating, brush each muffin lightly with 1/4 cup (56g) melted unsalted butter, then immediately roll or dip the top in the cinnamon-sugar mix (1/2 cup granulated sugar + 2 teaspoons ground cinnamon). For minis, roll quickly to avoid sogginess. Let the coating set on the rack before stacking in a container.
