Ingredients You’ll Need
Getting this cake just right means using a handful of simple, trusty ingredients that each play an important role in the final flavor, texture, and appearance. These basics come together effortlessly to create a cake that’s moist, flavorful, and festive.
- Pistachio Instant Pudding Mix: Adds that signature nutty pistachio flavor and luscious moisture to the cake batter.
- Yellow Cake Mix (or white cake mix): Provides a fluffy, tender cake base that balances perfectly with the pudding mix.
- Vegetable Oil: Keeps the cake wonderfully moist without weighing it down.
- Water: Essential to hydrate the dry ingredients and help form the batter’s silky texture.
- Large Eggs: Bind everything together and add richness to the cake.
- Vanilla Extract: Enhances overall flavor with a gentle sweetness and depth.
- Powdered Sugar: The base for the glaze, adding a sweet finish and smooth texture.
- Milk: Thins the glaze to the perfect consistency, making it easy to pour and coat the cake.
- Almond Extract (optional): Adds a subtle nutty punch that complements the pistachio beautifully when you decide to use it.
- Green Food Coloring (optional): For that unmistakable festive glow that screams Saint Patrick’s Day fun.
How to Make Saint Patrick’s Day Pistachio Pudding Cake Recipe
Step 1: Preheat the Oven
Start by setting your oven to 350°F (175°C). Getting the oven ready early ensures that your cake bakes evenly and rises just right. It’s a simple step, but it’s how you guarantee that perfect crumb and golden edges.
Step 2: Prepare the Cake Batter
In a large mixing bowl, combine the yellow cake mix and pistachio pudding mix. Add the vegetable oil, water, eggs, and vanilla extract to the dry ingredients. If you want an extra flavor boost, this is the time to stir in the almond extract, too. For a festive touch, add a few drops of green food coloring and gently mix until the color is uniform. It’s already starting to come alive now!
Step 3: Beat the Batter
Using an electric mixer, start beating on low speed for about 30 seconds to combine the ingredients without splattering. Then increase to medium speed and continue beating for 2 minutes until the batter is smooth, creamy, and completely lump-free. This step is key to achieving a light, airy texture in the finished cake.
Step 4: Bake the Cake
Pour the batter into a greased or parchment-lined 9×13 inch baking pan. Slide it into the preheated oven and let it bake for 30 to 35 minutes. Keep an eye out and check with a toothpick around the 30-minute mark – it should come out clean or with a few moist crumbs when the cake is perfectly baked.
Step 5: Cool the Cake
Once out of the oven, allow the cake to cool in the pan for 10 to 15 minutes. This rest period helps the cake set so it won’t stick or crumble when you transfer it. Afterward, move the cake to a wire rack to cool completely before glazing. Cooling the cake fully is essential for the glaze to set flawlessly without melting away.
Step 6: Make the Glaze
Whisk together powdered sugar and milk in a small bowl until smooth and pourable. Add green food coloring if desired to continue the festive Saint Patrick’s Day vibe. The glaze is sweet and shiny, creating that irresistible glossy coat on top of the cake.
Step 7: Glaze the Cake
Pour or drizzle the glaze evenly over the cooled cake, letting it cascade down the sides for maximum appeal. Let the glaze sit at room temperature for a few minutes to firm up before slicing. This finishing touch sends the Saint Patrick’s Day Pistachio Pudding Cake Recipe over the top in taste and presentation.
How to Serve Saint Patrick’s Day Pistachio Pudding Cake Recipe

Garnishes
Enhance your Saint Patrick’s Day Pistachio Pudding Cake Recipe by topping it with chopped roasted pistachios, a sprinkle of edible gold glitter, or tiny shamrock candies. These little details not only add texture but also turn your cake into a festive masterpiece that’s as fun to look at as it is to eat.
Side Dishes
Pair this cake with a scoop of vanilla or mint ice cream for a creamy contrast, or serve alongside fresh berries to add a bright, tangy balance. A cup of Irish coffee or a green tea latte also makes a lovely, complementary beverage option for the full Saint Patrick’s Day experience.
Creative Ways to Present
Slice your cake into bite-sized squares for a party platter, or plate individual servings with a dollop of whipped cream and a sprig of fresh mint. You can also turn it into mini trifle cups by layering crumbled cake with whipped cream and chopped pistachios. Presentation is all about making this Saint Patrick’s Day Pistachio Pudding Cake Recipe feel extra special and inviting.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cake covered tightly with plastic wrap or stored in an airtight container at room temperature for up to two days. For longer freshness, refrigeration works well and can extend its life up to five days while maintaining its texture and flavor.
Freezing
You can freeze this cake by wrapping it securely in plastic wrap and then aluminum foil. Freeze for up to two months. When you’re ready to enjoy it again, thaw overnight in the refrigerator for the best texture and taste.
Reheating
If you prefer your cake slightly warm, pop a slice into the microwave for 10 to 15 seconds. Avoid overheating to keep the glaze intact. Slightly warmed slices bring out the pistachio flavor beautifully and feel just like fresh-baked.
FAQs
Can I use homemade pistachio pudding instead of instant mix?
While homemade pudding is delicious, instant pudding mix helps achieve the right consistency and baking chemistry in this recipe. Using instant pudding ensures the cake is moist and bounces back with that signature texture every time.
Is it necessary to use green food coloring?
Nope! The cake tastes fantastic without it. Food coloring is just for fun to boost the Saint Patrick’s Day theme, but the natural pistachio flavor stands strong on its own.
Can I make this cake gluten-free?
Absolutely! Just swap out the yellow cake mix for a gluten-free cake mix, and make sure your pudding mix is gluten-free too. The rest of the ingredients are naturally gluten-free, so no fuss there.
What other nuts can I substitute for pistachios?
Pistachios provide a unique flavor here, but you could experiment with almond or hazelnut pudding mixes if you want a different nutty twist. Just remember that the flavor and color will vary from the original Saint Patrick’s Day Pistachio Pudding Cake Recipe experience.
Can I double the recipe for a larger crowd?
Yes, doubling the recipe works well! Just use a larger baking pan or two pans and extend the baking time slightly. Keep checking with a toothpick from the 35-minute mark onward to avoid overbaking.
