Pistachio Pudding Cake

Who doesn’t love pudding cake? It’s one of my favorites. So moist and creamy. Add in a little pistachio and it’s a pleasant surprise!

Pistachio Pudding Cake

1 white cake box
3 eggs
1 small package of instant pistachio pudding
1 cup of Sprite

1 small package of instant pistachio pudding
1 8 oz. container of Cool Whip
(optional) 1 cup of crushed pistachios

Equipment Needed:
2 mixing bowls
Fat Daddio’s round cake pan
Cake stand

Step 1:

Pour all of the ingredients to make the cake into a mixing bowl, adding the Sprite last. (This is one of the parts that kids love! The chemical reaction of the Sprite makes your bowl fill up with green fizz!)

Step 2:

Mix all of the ingredients together and then bake the cake using the directions from the box.

Step 3:

While letting your cakes cool, mix the box of instant pistachio pudding using half a cup less milk than directed and chill. When the pudding is ready, add the 8 oz. container of Cool Whip to it.

*NOTE: Let your cakes cool in the freezer. It really helps the pudding frosting to stick to them. Also, the less milk you use to make the pudding for the frosting, the thicker your frosting will be.

Mix the Cool Whip and pistachio pudding together. Let cool in the refrigerator for a few minutes.

Step 4:

Place the first layer of cake onto a cake stand and add frosting on top, then let chill for a few minutes. Repeat this until all of the layers of cake have frosting on top. Let the cake chill for about 15 minutes.

Step 5:

After the cake has chilled, then proceed to frost the rest of it, adding more to the top and covering the sides. Sprinkle the crushed pistachios on top of the cake.

*NOTE: If you’ve never worked with pudding frosting then you should know that it is more runny than a regular butter cream frosting. This is why it’s important to keep the cake chilled. If you are not going to eat the cake right away, I would suggest making it in a regular 9 x 13″ pan. A pudding cake will keep longer this way.

Serve chilled and enjoy!

    Wondering if Ginger Ale could be substituted for the Sprite or if there’s a reason Sprite needs to be used? Thanks!

    I’ve made it with Vernors. Excellent! Does it matter if the sprite is flat?

      I’ve never tried it with flat soda,I would think the bubbles might help a bit though!
