Spiced Eggnog Muffins with Streusel Topping

for the muffins:

1. Preheat oven to 375° F. Line 12 regular size muffin cups with paper liners and set aside.
2. In a medium bowl, combine flour, sugar, baking powder, cinnamon, nutmeg, and cloves. Make a well in the center of flour mixture and set aside.
3. In another medium bowl, combine eggs, eggnog, butter, and vanilla. Add mixture all at once to flour mixture. Stir just until moistened. Batter will be a bit lumpy. Divide batter between prepared muffin cups.

for the streusel topping:

1. In a small bowl, combine flour, sugar, nutmeg, and salt. Using a rigid pastry blender or fork, cut in butter until mixture resembles coarse crumbs. Sprinkle topping over muffin batter.
2. Bake for about 18 minutes, or until golden and a wooden toothpick inserted in centers comes out clean. Cool in pan on a wire rack for 5 minutes. Remove from pan and serve warm.
