For the Cake

- 5.1 ounces instant pistachio pudding can use a pack and a half of the smaller packs

For The Frosting
- 5.1 ounces instant pistachio pudding
- 1 ¼ cup milk
- 8 ounces whipped topping like Cool Whip
- pistachios chopped, optional garnish
- Maraschino cherries optional garnish
Instructions
Making The Cake
- Preheat the oven to 350 degrees. Line a square 9 x 13 glass pan with parchment paper or grease well with cooking oil or a baking nonstick spray. Place the butter in a small bowl. Melt the butter in the microwave, about 1 minute.
- In a second large bowl add the yellow cake mix, the first box of instant pistachio pudding mix, eggs, club soda and melted butter. Stir until fully mixed with a spatula or an electric mixer.
- Chop the pistachios coarsely. Fold in the pistachios into the batter.
- Pour batter for the cake into the prepared pan. Bake in the oven for 35- 40 minutes or until cooked all the way through. Let the cake cool in the pan completely, at least 45 minutes. As a general rule, the cake should be cool to the touch.
Making The Frosting
- In a second large bowl add the second instant pudding mix and the milk. With a metal whisk, blend together the pudding mix and the milk.
- Add the whipped topping into the pudding mix. Fold the whipped topping into the mixture with a silicone spatula.
- Frost the cooled cake. Add chopped pistachios and optional maraschino cherries to the top of the cake, then slice and serve.
Notes
- Please note you will need boxed pudding mixes for both the cake and the frosting.
- Taste the frosting before frosting the cake. If you prefer a little more pistachio flavor in the frosting, try blending in 1/2 teaspoon of vanilla extract and 1/4 teaspoon of almond extract. Almond extract in particular brings out the pistachio flavor, and the combination is extra delicious.
- You can also add a little more green color to the frosting with a few drops of green food coloring.
