Upside-Down Pear Gingerbread Cake

Directions

1. Preheat oven to 350°. In a small saucepan, melt butter over medium heat; stir in brown sugar. Spread over bottom of a greased 9-in. round baking pan. Arrange pears over top.
2. For cake, mix milk and vinegar; let stand 5 minutes. In a large bowl, beat egg, brown sugar, molasses, melted butter and milk mixture until well blended. In another bowl, whisk flour, cinnamon, baking soda, ginger, salt and cloves; gradually beat into molasses mixture. Spoon carefully over pears.
3. Bake until a toothpick inserted in center comes out clean, 25-30 minutes. Cool 10 minutes before inverting onto a serving plate. Serve warm or at room temperature with whipped cream, if desired.
