Cake Preparation

Now that you’ve gathered all your ingredients and tools, let’s get started on making this delicious Watergate Cake. The preparation process is easy and doesn’t require any advanced baking skills. In just a few steps, you’ll have a fluffy cake that will be the star of any occasion!

Step 1: Mix the Cake Batter

Begin by preheating your oven to 350°F (175°C) and greasing your 9 x 13-inch baking dish with nonstick cooking spray. Set it aside for later.

In a large bowl, combine the white cake mix, vegetable oil, pistachio pudding mix, eggs, and 7UP (or your preferred soda). Using an electric mixer, beat the mixture on low speed for about 30 seconds. This ensures that the dry ingredients are evenly combined with the wet ingredients. Then, increase the speed to medium and beat for an additional 3-4 minutes, making sure to scrape down the sides of the bowl to incorporate all the ingredients properly.

Step 2: Fold in the Pecans and Coconut

Once your cake batter is smooth, gently fold in the chopped pecans and sweetened coconut flakes. These ingredients give the cake its signature texture and flavor. Be careful not to overmix; just fold until everything is evenly distributed throughout the batter.

Step 3: Bake the Cake

Pour the batter into the prepared baking dish and spread it evenly. Place the dish in the preheated oven and bake for about 35-40 minutes, or until a toothpick inserted into the center comes out clean. The cake should have a light golden color on top.

Once the cake is done baking, remove it from the oven and allow it to cool in the pan for about 10 minutes. Afterward, transfer the cake to a wire rack to cool completely before frosting it. This step is crucial, as you don’t want the frosting to melt or slide off a warm cake.

Making the Frosting and Decorating the Cake

Now that your Watergate Cake is cool, it’s time to prepare the frosting and give the cake its finishing touches. The frosting is just as important as the cake itself, so let’s make sure we get it right!

Step 1: Prepare the Pistachio Frosting

In a medium bowl, whisk together the instant pistachio pudding mix and cold milk. Continue whisking for about 1-2 minutes until the mixture begins to thicken slightly. This will create a smooth base for your frosting.

Next, carefully fold in the thawed whipped topping (like Cool Whip). The whipped topping adds lightness and creaminess to the frosting, giving it a soft, airy texture. Stir gently until the frosting is fully combined, and be sure not to deflate the whipped topping too much.

Step 2: Frost the Cake

Once the frosting is ready, spread it evenly over the cooled cake using a spatula. Be generous with the frosting to create a thick, smooth layer. The creamy pistachio frosting will complement the nutty and coconut flavors in the cake, giving it a perfect balance.

Step 3: Add the Toppings

To make your Watergate Cake even more festive, sprinkle the sweetened coconut flakes and chopped pecans over the top of the frosted cake. These ingredients not only add texture but also enhance the flavor of the cake. If you want to make the cake even more eye-catching, garnish each slice with a maraschino cherry for a pop of color and a touch of extra sweetness.

Step 4: Let It Set

Allow the cake to sit for a few minutes after frosting it, so the toppings adhere properly. The cake can be served immediately, or you can refrigerate it for a while to let the flavors meld and the frosting set.

Serving and Storing Your Watergate Cake

Serving Suggestions

Your Watergate Cake is now ready to be enjoyed! This cake is perfect for a variety of occasions, whether it’s a family gathering, a holiday celebration, or a casual afternoon treat. The nutty pistachio flavor and creamy frosting make it a crowd-pleaser that pairs wonderfully with a cup of coffee or tea.

If you want to elevate the presentation, consider serving individual slices with a maraschino cherry on top or even a drizzle of chocolate sauce for an added twist. It also makes for a beautiful dessert at parties and potlucks, where it’s sure to stand out.

How to Store Leftovers

While the Watergate Cake is best enjoyed fresh, you can store any leftovers to savor later.

Room Temperature: If you plan to finish the cake within a couple of days, you can store it in an airtight container at room temperature. This will keep the cake fresh and moist for up to 2 days. Just be sure to avoid exposing it to heat or direct sunlight.
Refrigeration: For longer storage, place the cake in an airtight container in the refrigerator. It will stay fresh for about 4-5 days, and the flavors will continue to meld and develop.

Freezing the Cake

If you want to preserve the Watergate Cake for an extended period, you can freeze it. Here’s how:

To freeze the cake: Wrap the cake (without frosting) tightly in plastic wrap, followed by a layer of aluminum foil. You can also freeze individual slices wrapped individually for easy access.
To freeze the frosting: If you made extra frosting, you can freeze it in an airtight container or a resealable plastic bag.
To thaw: When you’re ready to enjoy the cake again, simply let it thaw at room temperature for a few hours or refrigerate overnight. Frost and serve as usual!
