Ingredients

  • 6 tablespoons poppy seeds
  • 1 cup buttermilk
  • 1 cup butter, softened
  • 1-1/2 cups sugar
  • 4 large eggs, separated
  • 2-1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/3 cup sugar
  • 2 teaspoons baking cocoa
  • 1 teaspoon ground cinnamon

Method

  • Place poppy seeds and buttermilk in a bowl; soak for 2 hours. In a large bowl, cream butter and sugar until light and fluffy. Add egg yolks; beat well. Combine the dry ingredients; add to creamed mixture alternately with poppy seed mixture.
  • In another bowl, beat egg whites until stiff. Fold into batter; set aside.
  • Combine filling ingredients; sprinkle a third into a greased and floured 10-in. fluted tube pan. Top with half of batter; sprinkle with half of the remaining filling. Cut through with a knife to swirl. Repeat with remaining batter and filling.
  • Bake at 350° for 1 hour. Turn out immediately onto wire rack to cool.
