Ingredients You’ll Need
- 1 cup (2 sticks) unsalted butter, softened: This adds richness and moisture to your cake. If you’re out of unsalted butter, you can use salted butter and reduce the added salt in the recipe.
- 2 1/2 cups all-purpose flour: The base of your cake, providing structure. For a gluten-free version, a 1:1 gluten-free flour blend works well without sacrificing texture.
- 1/2 teaspoon baking powder: This helps the cake rise and become fluffy. Be sure to check the expiration date for freshness.
- 1/2 teaspoon baking soda: Works in tandem with the baking powder to create a lighter cake.
- 1/2 teaspoon fine salt: Enhances flavor and balances the sweetness.
- 1 1/4 cups buttermilk, well shaken: Adds moisture and a slight tang. If you don’t have buttermilk, make your own by combining regular milk with 1 tablespoon of vinegar or lemon juice.
- 2 teaspoons pure vanilla extract: Adds a warm flavor that complements the lime perfectly. Always opt for pure over imitation for the best taste.
- 2 cups granulated sugar: Sweetens the cake beautifully. If you’re aiming for a lighter option, consider using half the amount or a sugar substitute.
- 3 large eggs, lightly beaten: Provides moisture and helps with the structure of the cake.
- 3 ounces lime gelatin: Infuses the cake with vibrant lime flavor. Feel free to experiment with other flavors as well!
- 2 cups heavy cream, cold: Essential for that fluffy whipped topping you’ll spread over the cake.
- 1 tablespoon granulated sugar (for cream): Sweetens the whipped cream without overpowering it.
- Green sanding sugar: Adds a festive touch—perfect for St. Patrick’s Day!
How to Make St. Patricks Day Lime Poke Cake
Preheat the Oven: Begin by preheating your oven to 350°F. To ensure easy removal later, butter a 9×13-inch baking pan.
Whisk the Dry Ingredients: In a medium 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 step ensures an even distribution of the leavening agents.
Combine the Wet Ingredients: In a spouted measuring cup, mix 1 1/4 cups buttermilk and 2 teaspoons pure vanilla extract. This makes it easy to pour into your batter later.
Cream the Butter and Sugar: In a large mixing bowl, cream 1 cup (2 sticks) unsalted butter and 2 cups granulated sugar together at medium speed for about 5 minutes, or until the mixture is fluffy and light in color. This step incorporates air, helping the cake rise beautifully.
Add the Eggs: Slowly incorporate 3 lightly beaten eggs into the butter mixture, ensuring they are well blended before moving on to the next step.
Combine Wet and Dry Mixtures: Gradually add alternating portions of the flour mixture and the buttermilk mixture into the butter mixture, starting and ending with the flour. This creates a well-blended batter without overmixing.
Bake the Cake: Spread the batter evenly into the prepared baking pan and bake for about 30 minutes, or until the cake is golden and a toothpick inserted in the center comes out clean. Let it cool in the pan for about 30 minutes.
Poke the Cake: Using a fork, poke holes about 1 inch apart all over the warm cake. These holes will allow the gelatin to seep in and flavor the cake.
Prepare the Lime Mixture: Dissolve 3 ounces of lime gelatin in 1 cup of boiling water, then mix in 1/2 cup of cold water. Carefully pour this mixture over the poked cake, ensuring it seeps into all the holes.
Chill: Refrigerate the cake for at least 2 hours to allow it to set and absorb the lime flavor fully.
Whip the Cream: In a chilled bowl, whip 2 cups of cold heavy cream with 1 tablespoon of granulated sugar and a splash of vanilla until fluffy peaks form. This will be your delicious topping.
Frost the Cake: Spread the whipped cream over the chilled poke cake evenly. For that festive touch, sprinkle green sanding sugar all over the top before serving.

Storing & Reheating
To store your leftover cake, cover it with plastic wrap or transfer it to an airtight container and keep it in the refrigerator for up to 4 days. If you’d like to save it for longer, you can freeze the cake for up to 3 months. Just be sure to wrap it tightly to prevent freezer burn. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight. The flavor may mellow slightly, but the cake remains tasty and refreshing. For a little texture boost after freezing, consider adding a fresh dollop of whipped cream.
Chef’s Helpful Tips
- To avoid a heavy cake, ensure your butter is softened, but not melted, as melted butter may yield a denser texture.
- Keep your eggs at room temperature before incorporating them; this helps with mixing and results in a lighter cake.
- Don’t skip the chilling time! This is when the flavor develops, and the cake becomes truly irresistible.
- If you’re short on time, skip the homemade whipped cream and opt for a store-bought alternative, but fresh is always best!
- Feel free to experiment with different flavored gelatins or toppings for a fun twist, especially as seasons change.
The vibrant, fresh flavors of this zesty treat may just become a new family favorite. With each slice, you get a burst of lime that’s delightful against the fluffy whipped cream.

Recipe FAQs
Can I make this poke cake in advance?
Absolutely! You can prepare the cake a day ahead of time and refrigerate it without the whipped cream. Just add the whipped topping on the day of serving for best texture.
What can I substitute for buttermilk?
If you don’t have buttermilk on hand, you can create a quick substitute by adding 1 tablespoon of vinegar or lemon juice to 1 1/4 cups of milk. Let it sit for about 5 minutes before using.
How do I prevent my cake from getting soggy?
The key is to let the cake cool completely before pouring the gelatin mixture over it. This allows the holes to absorb the liquid without becoming overly soggy.
Can I use another flavor of gelatin?
Definitely! Experimenting with different gelatin flavors can lead to delicious new creations. Just keep in mind that the colors and tastes will vary.
