📝Ingredients

For this pistachio cake recipe, you need the following ingredients:

• 2 boxes (3.4 ounces each) instant pudding mix, pistachio flavored
• 1 box white cake mix
• 1 cup 7-Up (or other lemon lime soda)
• 3 egg whites
• 1 cup vegetable oil
• 1½ cups cold milk
• 2 envelopes of Dream Whip

👩🏻‍🍳How To Make Watergate Cake

If you have never worked with Dream Whip, don’t let it intimidate you. Dream Whip is a commercial powdered mix to make whipped cream. If you have an electric mixer or hand mixer, you won’t have any problems with it.

To make Watergate Cake, start by preheating your oven to 350 degrees (Fahrenheit). While it is warming up, grease and flour a 9×13 cake pan. Alternatively, you can use Baker’s Joy to prep the pan. Just spray a light layer over the bottom and inside.

For the cake, blend one box of instant pistachio pudding mix, a box of white cake mix, 7-Up, egg whites, and a cup of vegetable oil in a large mixing bowl of an electric mixer for 5 minutes at medium speed.

Pour the cake batter into the prepared cake pan and bake for 30 – 35 minutes or until a toothpick inserted in the middle comes out clean.

Cool the cake completely before making the pistachio frosting/whipped topping, aka cover-up icing. [I like to place the cake pan on a wire rack to allow air circulation and speed up the cooling process.]

For the topping, beat 1 package of the pudding mix, milk, and the Dream Whip. Beat at high speed until it is thick and soft peaks form.

Spread the topping on top of the cake, cover it with plastic wrap, and place it in the refrigerator. This cake will need to be kept cold at all times.

If you plan on taking it to a family get-together, church potluck, or some other event, pack it in a container and include ice packs. Remember, the icing is made with a dairy product and needs to be kept cold.

To add a pop of color, serve slices of cake with a maraschino cherry on top.
