Time 1h15m

Number Of Ingredients 14

10 tablespoons (1 1/4 sticks) unsalted butter
3/4 cup packed light-brown sugar
2 small pink grapefruit
1 1/2 cups flour
1 1/2 teaspoons baking powder
1 teaspoon ground cinnamon
3/4 teaspoon ground ginger
1/2 teaspoon baking soda
1/4 teaspoon ground allspice
1/2 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/2 cup milk
Whipped cream, (optional)

Steps:

Preheat oven to 350 degrees. Put 4 tablespoons butter in a 9-inch round baking pan. Place the pan in the oven just long enough to melt the butter. Remove pan from oven; scatter 1/2 cup brown sugar evenly over the melted butter.
With a sharp knife, peel the grapefruit, removing all pith, and slice. Arrange the slices to cover the bottom of the pan.
In a bowl, stir together flour, baking powder, cinnamon, ginger, baking soda, and allspice. In a separate bowl, using an electric mixer, beat remaining 6 tablespoons butter until creamy. Add granulated sugar and remaining 1/4 cup brown sugar; beat until well combined. Beat in eggs one at a time. Beat in vanilla. Alternately add dry ingredients and milk to butter mixture, beginning and ending with dry ingredients.
Pour batter over grapefruit in pan. Bake 45 minutes or until a toothpick inserted in center comes out clean. Cool 5 minutes; turn cake out onto serving plate. Serve warm or at room temperature, with whipped cream if desired.
