Grease or well-butter the cups of a standard-size muffin tin.
In a large bowl, whisk together the 1 cup plain yogurt, 2 eggs, ¼ cup unsalted butter, and ¼ cup molasses.
In a medium bowl, whisk together the 1 ½ cups oat flour , ¾ cup brown sugar, 1 ½ teaspoons baking powder, 1 teaspoon cinnamon, 1 teaspoon ground ginger, ¼ teaspoon cloves, and ¼ teaspoon fine sea salt. Gently fold the flour mixture into the yogurt mixture.
Divide the mixture evenly among the prepared muffin tin.
Preheat the oven to 375℉ and rest the batter while the oven heats. Then, bake for 15-20 minutes, or until a tester inserted into the center of a muffin comes out clean. Let cool in the pan for a few minutes, then run a knife around the edges and transfer muffins to a wire rack to cool completely.
