Method
Prepare the pan
- Heat the oven to 375°F.
- Line a 12-cup standard muffin pan with paper liners.
Make the streusel
- Stir the oats, brown sugar, and cinnamon in a small bowl.
- Mix in the melted butter until clumps form.
Make the muffins
- Whisk the flour, granulated sugar, baking powder, salt, and nutmeg in a large bowl.
- Whisk the egg, eggnog, canola oil, and vanilla in a medium bowl.
- Fold the egg mixture into the dry ingredients just until no dry flour remains.
- Divide the batter evenly among the muffin cups.
- Sprinkle the streusel over the tops.
- Bake for 18–22 minutes, until the tops are golden and a toothpick inserted in the center of a muffin comes out clean or with a few moist crumbs.
- Let the muffins rest in the pan for 5 minutes.
- Transfer the muffins to a wire rack to cool.
Notes
For tender muffins, fold the wet ingredients into the dry ingredients just until no dry flour remains. Store covered in the refrigerator for up to 3 days; freeze for up to 3 months. For a dairy-free variation, use dairy-free eggnog and plant-based butter.
