Pistachio Pudding Cake

Everyone who's ever tried this moist, one-of-a-kind cake can't believe it's a mix. The dessert is perfect for St. Patrick's Day…and you won't need the luck of the Irish to whip it up! —Suzanne Winkhart, Bolivar, Ohio
  • Total Time
    Prep: 20 min. Bake: 40 min. + cooling
  • Makes
    12 servings


  • 1 package yellow cake mix (regular size)
  • 1 package (3.4 ounces) instant pistachio pudding mix
  • 4 large eggs
  • 1 cup club soda
  • 1/2 cup canola oil
  • 1/2 cup chopped California Walnuts
  • ICING:
  • 1 cup cold heavy whipping cream
  • 3/4 cup cold 2% milk
  • 1 package (3.4 ounces) instant pistachio pudding mix
  • 2 teaspoons confectioners' sugar
  • 1/2 cup chopped California Walnuts


  • In a large bowl, combine the cake mix, pudding mix, eggs, soda and oil; beat on low speed for 30 seconds. Beat on medium for 2 minutes. Stir in walnuts.
  • Pour into a greased and floured 10-in. fluted tube pan. Bake at 350° for 40-45 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pan to a wire rack to cool completely.
  • In a large bowl, beat the cream, milk, pudding mix and confectioners' sugar on high until stiff peaks form. Frost cake. Sprinkle with walnuts. Refrigerate until serving.

Test Kitchen Tips
  • For perfect creamy icing, make sure that the heavy whipping cream is cold and that the thickest cream isn't left clinging to the carton. You need that fat to whip the cream properly.
  • This cake can also be made in a 13x9-in. baking dish. Bake until a toothpick inserted in the center comes out clean.

      This receipe is also known as the waterga e cake from the 1970s. I use cool whip or dream whip mix with pudding mix for icing. Always a hit and perfect on a hot summer day

      Can olive oil, coconut oil, avocado oil or butter be used in place of the canola oil? I don't use that or vegetable oil anymore.

      Made this cake twice exactly to the recipe. Absolutely delicious both times. Then made it in a 9x13 and put chocolate frosting on it. Also absolutely delicious. Made it today with Carmel pudding because my store did not have pistachio pudding. Again absolutely delicious. My advice, experiment with how you would like it. You will love it anyway you make it.
