Pistachio Pudding Cake

Ingredients

Here are the ingredients you’ll need to bring this dreamy cake to life:

  • 15.25 ounces yellow cake mix (1 box)
  • 5.1 ounces instant pistachio pudding (1 pack and a half of smaller packs)
  • 3 large eggs
  • 1 cup club soda (or lemon-lime soda)
  • 1 cup salted butter, melted
  • 1 cup shelled and chopped pistachios (plus extra for garnish)
  • 5.1 ounces instant pistachio pudding (for frosting)
  • 1 ¼ cup milk
  • 8 ounces whipped topping (like Cool Whip)
  • Optional garnish: Chopped pistachios, maraschino cherries

Making The Cake

Pistachio Pudding Cake

Preheat and Prepare Pans

First things first, preheat your oven to 350°F. Take a 9×13 glass baking dish and prepare it by lining it with parchment paper or greasing it with non-stick spray. This simple step will save you from any potential sticky situations later.

Mix the Batter

In a large mixing bowl, combine the yellow cake mix, the first pack of instant pistachio pudding mix, eggs, club soda, and melted butter. Use a spatula or an electric mixer to mix everything together until it’s well combined. You’ll want this mixture to be smooth and fluffy.

Add Chopped Pistachios

Now it’s time for our star ingredient! Coarsely chop the pistachios before gently folding them into the batter. This will ensure you get that delightful crunch in every slice.

Bake the Cake

Pour the batter into the prepared baking pan, spreading it out evenly. Bake for 35-40 minutes, but keep an eye on it. A toothpick inserted in the center should come out clean—this is the sign that your cake is ready. Once done, let it cool completely in the pan, which should take about 45 minutes.

Making The Frosting

Prepare the Frosting Mixture

While the cake cools, let’s prepare the frosting. In a separate bowl, add the second pack of instant pistachio pudding mix to the milk. Whisk together until it’s nice and smooth.

Fold in the Whipped Topping

Now, gently fold the whipped topping into the pudding mixture. Mix just until combined, taking care not to deflate the fluffy texture of the whipped topping.

Frost the Cake

Once your cake has cooled, spread the frosting evenly over the top. For that finishing touch, garnish with additional chopped pistachios and optional maraschino cherries. Your cake is now not just a treat, but a work of art!

Serving Suggestions

When it comes to serving, there are many delightful options. You could serve it with a side of fresh fruit or a dollop of whipped cream for added decadence. Pairing it with coffee or tea creates the perfect afternoon treat, making each bite even more enjoyable.

Tips for Success

Here are some handy tips to make sure your baking experience goes smoothly:

  • Ensure the cake is fully cooled before frosting, as this prevents melting and keeps your frosting looking pristine.
  • Feel free to adjust the amount of pistachios based on your desired crunch. More nuts equal more fun!

Variations

If you want to mix things up, consider these variations:

  • Substitute almond extract for a different nut flavor. This can add an interesting and delightful twist to the cake.
  • For extra richness, add a layer of cream cheese frosting beneath the pistachio frosting. It’s an indulgent way to elevate your treat.

Storage Tips

If you have leftovers (though I doubt that), store them in an airtight container in the fridge for up to 3 days. The cake also freezes well; just wrap it tightly and enjoy it within 2 months. This way, you can always have a delicious slice ready to go any time you crave a little sweetness!
