Gingerbread Pound Cake

Preheat the oven to 325 degrees F (165 degrees C). Grease and flour a 12-cup fluted tube pan (such as Bundt®) well.

Beat butter in a mixing bowl on medium speed until soft and creamy, about 2 minutes; gradually add 1 cup white sugar, beating at medium speed for 5 to 7 minutes. Add eggs one at a time, beating just until yellow disappears; batter may look a bit curdled.

Combine flour, ginger, cinnamon, cloves, and baking soda in a separate bowl. Combine molasses and sour cream in another bowl. Add dry ingredients to the batter alternately with molasses mixture, beginning and ending with dry ingredients. Mix on low speed until each addition is just blended. Pour into the prepared pan.

Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, about 1 hour. Cool cake in the pan on a wire rack for 10 to 15 minutes; remove cake from pan and cool completely, about 30 minutes more.

While cake cools, combine water, white sugar, and cornstarch in a saucepan; cook over medium heat, stirring constantly, until smooth and thickened. Stir in lemon juice, butter, and lemon zest and cook until warmed through.

Sprinkle cooled cake with powdered sugar and serve with lemon sauce.
