Cake with powder sugar and blueberry on wooden background, space for text Premium Photo


3/4 cup butter, room temperature

1 1/2 cups white sugar

3 eggs

1 teaspoon vanilla extract

1 cup sour cream

2 1/2 cups all-purpose flour

1 teaspoon baking soda

1 teaspoon baking powder

1/2 cup chopped walnuts

1 tablespoon ground cinnamon

1/4 cup white sugar


  • Beat butter and sugar with an electric mixer in a large bowl until light and fluffy. The mixture should be noticeably lighter in color.
  • Add eggs one at a time, allowing each egg to blend into the butter mixture before adding the next. Mix in vanilla.
  • Combine flour, baking soda, and baking powder. Pour flour mixture into batter alternately with the sour cream, mixing until just incorporated.
  • Fold in walnuts, mixing just enough to evenly combine. Fill the pre-heated bundt cake maker half full.
  • Mix the remaining 1/4 cup of white sugar with the cinnamon.
  • Sprinkle cinnamon sugar over the batter in the pan. Fill bundt cake maker with more batter in heaping spoonfuls over the filling, covering it as best you can.
  • Rotate the unit clockwise 180° to the bottom side. Allow cake to bake undisturbed for 14 to 15 minutes.
