Preheat the oven to 325 degrees F (165 degrees C). Grease two 24-cup mini muffin pans.
Combine molasses, margarine, white sugar, brown sugar, egg, lemon zest, baking soda, cinnamon, ginger, and cloves in a large bowl. Beat using an electric mixer at medium speed until well mixed. Add flour and sour cream; continue beating until well mixed.
Spoon batter into the prepared muffin cups, filling each 3/4 full.
Bake in the preheated oven until a toothpick inserted into the center of a muffin comes out clean, 10 to 12 minutes. Let stand for 5 minutes before removing from the pans.
