If you are looking for an easy sweet treat to enjoy on St. Patrick’s Day, this St Patrick’s Day Bundt Cake is it. It’s fun, festive, and tastes fabulous. This cake includes 3 colors of cake and frosting. It’s kind of hard to tell in the pictures. I used gel food coloring from the grocery story. You will get better results with Wilton gel food coloring.

This festive St. Patrick’s Day Bundt Cake begins with a simple white cake mix as the base. To enhance the flavor and add extra moistness, you add in a packet of dry white chocolate pudding mix. Once the batter is prepared, it’s divided into three equal portions. One portion remains uncolored to retain the original white hue, while the second portion is transformed into a light green shade using green food coloring. The final portion is dyed a deeper, darker green for contrast. As you pour the batter into your Bundt pan, the three colors are layered alternately, then gently swirled together to create that marbled effect.

Instructions for St. Patrick’s Day Bundt Cake

Preparing the Batter

To start, preheat your oven to 350°F (175°C). While the oven is heating, grease and flour a 10-inch fluted tube pan. For best results, I recommend using Pam Baking Spray—just make sure it’s the baking version.

Next, in a large bowl, combine the cake mix, dry pudding mix, sour cream, oil, water, and eggs. Begin by beating the mixture on low speed until the ingredients are moist. Then, gradually increase the speed to medium and continue beating for 2 minutes, ensuring the batter is smooth and well-combined.

Once the batter is ready, divide it evenly into three separate bowls. Start by leaving one portion uncolored. Then, move on to the second portion and tint it with a few drops of green food coloring to achieve a light green shade. Finally, take the third portion and add more food coloring to create a rich, dark green hue.

Layering the Batter

After you prepare the batter, it’s time to layer it in the pan. First, pour the uncolored white batter into the prepared Bundt pan and spread it evenly to create the base layer.

Next, carefully add the light green batter on top of the white layer, spreading it gently to avoid mixing the colors too soon. Finally, pour the dark green batter over the light green layer, ensuring an even distribution.

Now, take a wooden skewer or toothpick and gently swirl it through the layers of batter. This step creates the marbled effect that makes this cake so special.

Baking the Cake

Once you layer and swirl the batter, place the Bundt pan in the preheated oven. Allow the cake to bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.

After baking, remove the cake from the oven and let it cool in the pan for 10 minutes. Next, carefully turn the cake out onto a wire rack to cool completely before moving on to the frosting.

Preparing the Cream Cheese Frosting

While the cake cools, you can begin preparing the frosting. Start by combining all the frosting ingredients in a bowl and beating them together until the mixture is smooth and creamy.

Just like the batter, divide the frosting into three equal portions. Begin by leaving one portion white. Then, color the second portion light green and the third portion dark green using food coloring.

Once colored, transfer each portion of frosting into its own quart-sized Ziploc bag. Snip a small corner off each bag to create a piping tool.

Decorating the Cake

To complete your masterpiece, generously sprinkle green sugar sprinkles and shamrock-shaped sprinkles over the cake. This final touch adds both charm and festivity to your dessert.with sprinkles! Use green sugar sprinkles and shamrock-shaped sprinkles to add that festive flair. Your cake is now ready to impress—this recipe serves 12 to 15 people.

Now it’s time to frost the cake! Begin by piping the white frosting over the cooled Bundt cake in decorative drizzles. Then, follow with the light green frosting, and finally, finish with the dark green frosting.

Frequently Asked Questions

Can I use a different flavor of cake mix?
Yes! While white cake mix works best for achieving vibrant colors, you can experiment with other flavors like vanilla. Just keep in mind that the base color of the cake mix might slightly affect the final appearance of the green layers.

Can I make this recipe without the pudding mix?
The pudding mix helps to enhance the flavor and ensure the cake is extra moist. If you don’t have pudding mix on hand, you can skip it, but the texture may be less soft and rich.

What type of food coloring should I use?
Gel food coloring is highly recommended because it provides more intense colors without thinning the batter or frosting. However, liquid food coloring can also work—just add it gradually to avoid over-coloring.

Can I prepare this cake in advance?
Definitely! You can bake the cake a day ahead and store it covered at room temperature. Frost it and add sprinkles closer to serving to keep the decorations looking fresh and vibrant.

What if I don’t have a Bundt pan?
If you don’t have a Bundt pan, you can use a regular round or square cake pan. The swirling effect will still look great, though it may lack the classic Bundt shape.

How do I store leftover cake?
Leftovers can be stored in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to a week or freeze individual slices for up to 3 months.

Can I use different sprinkles?
Absolutely! While green sugar sprinkles and shamrock-shaped sprinkles are perfect for St. Patrick’s Day, feel free to customize the sprinkles to match your personal style or another festive occasion.
