1/4 cup Cold Butter, cut into small cubes (1/2 stick) (for crumble)
1/4 cup Chopped Pecans or Walnuts (optional) (for crumble)
Instructions
Preheat oven to 375°F (190°C). Line a muffin tin with paper liners or grease well.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, nutmeg, cinnamon, and cloves.
In a separate bowl, whisk together the eggnog, eggs, melted butter, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix just until combined. Be careful not to overmix.
For the crumble topping: In a small bowl, combine the flour and brown sugar. Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Stir in the chopped nuts (if using).
Fill the muffin cups about 2/3 full with batter. Sprinkle the crumble topping evenly over the muffins.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Let the muffins cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely.
