How to Make St. Patrick’s Day Lime Poke Cake
Preheat: Begin by preheating your oven to 350°F (175°C). While that’s warming, butter a 9×13-inch baking pan to prevent sticking.
Whisk Dry Ingredients: In a mixing bowl, whisk together 2 1/2 cups all-purpose flour, 1/2 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon fine salt. This ensures an even distribution of the leavening agents throughout your cake batter.
Mix Wet Ingredients: In a spouted measuring cup, combine 1 1/4 cups well-shaken buttermilk and 2 teaspoons pure vanilla extract. This mixture will add both moisture and flavor to your cake.
Cream Butter & Sugar: In a large mixing bowl, cream together 1 cup softened unsalted butter and 2 cups granulated sugar using a hand mixer on medium speed for about 5 minutes, until it’s light and fluffy. This step is crucial for a tender cake as it helps to incorporate air.
Incorporate Eggs: Slowly pour in the 3 lightly beaten eggs, mixing thoroughly until fully combined. This will help give your cake a smooth consistency.
Combine Ingredients: Gradually add the dry flour mixture into the butter mixture, alternating with the buttermilk mixture. Start and end with the flour mixture to ensure everything blends together seamlessly.
Bake: Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula. Bake in the preheated oven for about 30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean. Once baked, remove from the oven and let it cool for 30 minutes.
Poke Holes: After cooling, take a fork and poke holes all over the cake, spacing them about 1 inch apart. These holes will allow the gelatin mixture to seep into the cake, enhancing its flavor.
Prepare Gelatin: In a bowl, dissolve 3 ounces of lime gelatin in 1 cup of boiling water, stirring until fully dissolved. Then mix in 1/2 cup of cold water. Pour this over the poked cake, allowing it to soak in, infusing each bite with delicious lime flavor.
Chill: Now, cover the cake and place it in the refrigerator for at least 2 hours. This cooling step lets those flavors meld beautifully and helps the cake set perfectly.
Whip Cream: In a chilled bowl, whip together 2 cups of cold heavy cream, 1 tablespoon of granulated sugar, and an extra hint of vanilla. Whip until soft peaks form—this is what will create that light, fluffy topping on your cake.
Top Cake: After chilling, spread the whipped cream generously over the lime-infused cake. Don’t forget to have some fun and sprinkle green sanding sugar on top for that delightful pop of color!
Serve: Slice, serve, and watch everyone enjoy a taste of spring with every forkful.

Storing & Reheating
To store your St. Patrick’s Day Lime Poke Cake, cover it tightly and keep it in the refrigerator. It’ll last up to 5 days, nestled within an airtight container to maintain its moistness. If you want to save some for a later day, you can freeze slices for up to 3 months. Wrap them securely in plastic wrap and then place them in a zip-top bag. When ready to indulge, simply thaw in the refrigerator overnight. The whipped cream may soften a touch, so a quick whip or squeeze of fresh cream can refresh it if desired.
Chef’s Helpful Tips
- Be sure to use room-temperature eggs and butter for easier mixing and a fluffier batter.
- For a more intense lime flavor, consider adding some freshly grated lime zest to the batter.
- If your whipped cream isn’t thickening, it might be too warm—try chilling your bowl and beaters before whipping.
- When poking holes in the cake, don’t skip this step! It’s vital for letting the gelatin blend into the cake evenly.
- Experiments with different flavor jellies can offer unique twists on this poke cake!
This dessert is not simply a cake; it’s a vibrant touch of festivity served on a plate. The zesty lime and airy whipped cream create the kind of refreshment that’s perfect for any day, not just St. Patrick’s Day.

Recipe FAQs
Can I use other flavors of gelatin?
Absolutely! While lime gelatin brings a unique zestiness to the cake, you can experiment with other flavors such as lemon, strawberry, or raspberry. Each will give you a deliciously different cake that still keeps the poke cake concept.
How do I prevent my cake from sticking?
Using a well-buttered pan or parchment paper is crucial for easy release. After baking, allow the cake to cool in the pan for a few minutes before inverting it onto a wire rack for complete cooling.
Can I make this cake gluten-free?
Yes! You can replace all-purpose flour with a gluten-free flour blend. Just make sure it has a good binding agent, like xanthan gum, to help achieve the same tender texture.
What if I don’t have buttermilk?
If you’re out of buttermilk, you can make a quick substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5 minutes to thicken before using.
