Ingredients 

• 2 cups all purpose flour
• 1 1/2 teaspoons powdered ginger
• 1 1/2 teaspoons cinnamon
• 1 cup butter
• 1 cup granulated sugar
• 1 large egg (beaten)
• 1/2 cup molasses
• 1/2 teaspoon salt
• 1 teaspoon baking soda
• 1/2 cup buttermilk

Instructions 

• Preheat the oven to 350 degrees.
• In a medium size bowl, mix together the flour, sugar, ginger and cinnamon. Cut in the butter and mix into the dry ingredients to make fine crumbs. Take out ½ cup crumbs and set them aside so you can sprinkle them on top of the cake batter.
• To the remaining crumbs, add the egg, molasses, salt, baking soda and buttermilk. Mix until the ingredients are well blended and the batter is smooth.
• Pour the batter into a greased, parchment paper or foil lined 8×8 pan.
• Sprinkle the remaining crumbs on top of the batter.
• Bake at 350 degrees for 40-45 minutes, or until a knife inserted into the cake comes out clean.
