Ingredients You’ll Need
1 cup (2 sticks) unsalted butter, softened: This is the base for your cake, giving it a rich flavor and tender crumb. Make sure you soften it to room temperature for smooth mixing.
2 1/2 cups all-purpose flour: This will form the structure of your cake. For a gluten-free version, try a 1:1 gluten-free flour blend.
1/2 teaspoon baking powder: Adds a bit of lift to help your cake rise perfectly.
1/2 teaspoon baking soda: Works in conjunction with the acidity of the buttermilk to provide fluffiness.
1/2 teaspoon fine salt: Enhances all the flavors and balances the sweetness.
1 1/4 cups buttermilk, well shaken: The tanginess of buttermilk adds moisture and a delightful flavor kick. You can swap in milk with a teaspoon of lemon juice if you’re out.
2 teaspoons pure vanilla extract: Pure vanilla elevates the cake’s flavor. Avoid synthetic varieties for best results.
2 cups granulated sugar: This creates a lovely sweetness. Adjust to your taste if you prefer it less sweet.
3 large eggs, lightly beaten: These help bind everything together and add moisture. Use room temperature eggs for better incorporation.
3 ounces lime gelatin: This is the star of your poke cake, infusing it with a punchy lime flavor.
2 cups heavy cream, cold: Whipped to create a luscious topping that makes this cake irresistibly creamy.
1 tablespoon granulated sugar (for cream): This adds just a touch of sweetness to your whipped cream.
Green sanding sugar, for sprinkling: For an extra festive touch, sprinkle this on top before serving.
How to Make St. Patricks Day Lime Poke Cake
Preheat your oven: Start by heating your oven to 350°F. Prep your 9×13-inch baking pan by buttering it generously so your cake slides out easily later.
Whisk dry ingredients: In a medium bowl, combine 2 1/2 cups all-purpose flour, 1/2 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon fine salt. This blend helps your cake rise and keeps it tender.
Mix wet ingredients: In a spouted measuring cup, mix together 1 1/4 cups of buttermilk and 2 teaspoons of pure vanilla extract. This will bring a lovely balance of flavors to the cake.
Cream butter and sugar: In a large mixing bowl, beat 1 cup (2 sticks) of softened unsalted butter and 2 cups granulated sugar together at medium speed for about 5 minutes. You’ll notice it becoming fluffy and pale; this step is crucial for a light texture.
Incorporate eggs: Slowly add in the 3 lightly beaten large eggs, mixing until well combined. This will enrich the cake and help it rise beautifully.
Combine mixtures: Gradually add in the flour mixture, alternating with the buttermilk mixture, starting and ending with the flour. This method helps keep everything well mixed without overworking the batter.
Bake: Spread the batter into the prepared pan and bake for about 30 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean. This smells heavenly, so be prepared for the yummy scent to fill your kitchen!
Cool and poke: Allow the cake to cool in the pan for about 30 minutes. Then, use a fork to poke holes about 1 inch apart all over the surface. This step allows the gelatin to seep in, creating that signature poke cake texture.
Prepare gelatin: In a bowl, dissolve 3 ounces of lime gelatin in 1 cup of boiling water. Then, mix in 1/2 cup cold water for a refreshing chill. Pour this flavorful mixture over the cooled cake, ensuring it fills the holes.
Chill: Cover the cake with plastic wrap and refrigerate for at least 2 hours. This allows the lime gelatin to set and infuse into every delicious bite.
Whip the cream: In a chilled bowl, whip 2 cups of cold heavy cream with 1 tablespoon of granulated sugar and an optional splash of vanilla until it forms soft peaks. This adds a lovely creamy layer on top!
Spread & garnish: Once your cake is fully chilled and set, spread the whipped cream over the top. For a finishing touch, sprinkle with green sanding sugar to match the festive vibe.

Storing & Reheating
Store any leftover cake covered in the refrigerator for up to 5 days. If you want to enjoy it later, you can freeze it for up to 3 months—just be sure to wrap it tightly in plastic wrap followed by aluminum foil. If you’re reheating, simply remove your portion from the freezer, thaw it in the fridge overnight, and serve chilled for the best texture. Keep in mind that while freezing won’t harm the flavor, the cream topping is best fresh.
Chef’s Helpful Tips
- Avoid over-mixing the batter once you add the flour; this can lead to a dense cake.
- For best results, start with room temperature eggs and softened butter – they mix more thoroughly.
- If your whipped cream isn’t holding peaks, make sure your bowl and beaters are cold and whip it until you get just the right texture.
- This cake can easily be made a day in advance; just add the whipped cream right before serving to keep it fresh.
- Experiment with different fruit gelatins for a fun twist on flavors!

Recipe FAQs
Can I make this cake gluten-free?
Absolutely! Just substitute the all-purpose flour with a gluten-free 1:1 baking flour, and you’re good to go! The texture and flavor will still be wonderful.
How do I store leftovers?
You can store any leftover cake in the refrigerator for up to 5 days; just cover it with plastic wrap to keep it moist. If you want to store it longer, you can freeze it for up to 3 months.
What’s a good substitute for buttermilk?
If you don’t have buttermilk on hand, you can easily make your own by adding 1 tablespoon of lemon juice or vinegar to regular milk and letting it sit for about 5-10 minutes. This will mimic the tangy flavor of buttermilk quite nicely.
Can I add fresh fruit on top?
Yes! Fresh sliced strawberries or blueberries would add a lovely touch and enhance the visual appeal of your St. Patrick’s Day lime poke cake. Just make sure to add them right before serving for the best texture.
