Ingredients (Makes 12 standard muffins)
For the Muffins:
- 1½ cups all-purpose flour
- ½ cup granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¼ teaspoon ground nutmeg (for that classic donut flavor)
- ½ cup milk (whole or 2% recommended)
- ¼ cup sour cream or plain Greek yogurt
- 1 large egg
- ¼ cup unsalted butter, melted and cooled
- 1 teaspoon vanilla extract
For the Cinnamon Sugar Coating:
- ¼ cup unsalted butter, melted
- ½ cup granulated sugar
- 1½ teaspoons ground cinnamon
Instructions
1. Preheat & Prep
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or lightly grease with nonstick spray.
2. Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and nutmeg. Set aside.
3. Mix Wet Ingredients
In a separate bowl, whisk the milk, sour cream, egg, melted butter, and vanilla extract until smooth and combined.
4. Combine & Fill
Pour the wet mixture into the dry ingredients. Stir gently until just combined—do not overmix.
Spoon the batter evenly into the prepared muffin tin, filling each cup about ¾ full.
5. Bake
Bake for 15–18 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean.
Let muffins cool in the pan for 5 minutes, then transfer to a wire rack.
6. Add the Cinnamon Sugar Finish
Once slightly cooled (but still warm), dip each muffin top in melted butter, then roll or sprinkle generously with the cinnamon sugar mixture.
Let set for a few minutes and enjoy warm or at room temperature.
Tips & Tricks
Want full coating? Roll the entire muffin in butter and cinnamon sugar for an extra indulgent finish

Make mini muffins—reduce bake time to 10–12 minutes
Add a pinch of cardamom or allspice for extra spice depth
Storage & Make-Ahead
- Room Temp: Store in an airtight container for up to 3 days
- Freezer: Freeze for up to 2 months (skip sugar coating until after thawing)
