Tender, moist, loaded with eggnog and nutmeg and topped with streusel, these eggnog muffins are the perfect way to kickstart the holiday season. A delightfully cozy treat for a chilly day, these muffins come together in 10 minutes and are perfect for holiday brunches.
Preheat the oven to 425F and line a muffin tin with 12 paper muffin cups; set aside.
Make the streusel topping.
Combine the streusel ingredients in a small bowl and gently stir until everything is just mixed together and crumbly; do not overmix; set aside.
Make the muffin batter.
In a medium-sized bowl whisk together the sugar and oil until the sugar starts to form small clumps; about 2 minutes.
Add in the eggs and whisk thoroughly, scraping the sides as necessary, until the sugar dissolves and the mixture has lightened in color and is smooth; about 5 minutes.
Add the baking powder, vanilla extract, nutmeg and salt to the egg mixture and whisk to combine.
Add the flour and eggnog to the egg mixture in batches, alternating between the flour and the eggnog, making sure each batch is thoroughly combined before adding in the next; start and end with the flour; after the last batch of flour is added the batter should be thick; do not overmix.
Spoon the batter into the prepared muffin cups, filling them almost to the top.
Sprinkle the streusel topping over each muffin; you should use all of the streusel.
Bake the muffins at 425F for 5 minutes, then, keeping the muffins in the oven, reduce the temperature to 350F.
Bake for an additional 15 minutes or until the muffin tops are a light golden brown and a cake tester or toothpick comes out clean.
Remove the muffins from the oven and let cool for at least ten minutes.
