How to Make St. Patricks Day Lime Poke Cake
Preheat the Oven: Begin by preheating your oven to 350°F. Butter a 9×13-inch baking pan generously. This will help the cake release easily once it’s baked.
Mix the Dry Ingredients: In a large 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. Making sure these are well combined ensures an even texture.
Combine Wet Ingredients: In a spouted measuring cup, mix 1 1/4 cups buttermilk and 2 teaspoons pure vanilla extract. This mixture brings in moisture and flavor to the cake.
Cream Butter and Sugar: In an electric mixer, beat 1 cup softened unsalted butter and 2 cups granulated sugar at medium speed for about 5 minutes. You’ll know it’s ready when the mixture is light and fluffy, creating a luscious base for your cake.
Incorporate Eggs: Slowly add the lightly beaten eggs one at a time to the butter and sugar mixture, mixing until fully combined after each addition. This step is crucial as it helps emulsify and creates a uniform batter.
Combine Dry and Wet Mixtures: Gradually alternate adding the dry flour mixture and the buttermilk mixture to the butter mixture, beginning and ending with the flour mixture. This technique maintains the cake’s tender crumb.
Bake the Cake: Pour the batter into the prepared baking pan, spreading it evenly. Bake in the preheated oven for 30 minutes, until the edges are golden and a toothpick inserted in the center comes out clean. Avoid opening the oven door too early, so it rises perfectly!
Poke Holes in the Cake: Once baked, cool the cake for about 30 minutes. Then, take a fork and poke holes every inch apart throughout the surface. This step allows the flavorful gelatin to seep in!
Prepare the Gelatin: In a separate bowl, dissolve 3 ounces of lime gelatin in 1 cup boiling water. Stir until fully dissolved; then add 1/2 cup cold water. This mixture is key for that refreshing flavor so don’t skip this.
Pour the Gelatin: Carefully pour the gelatin mixture over the poked cake, ensuring it seeps into all the holes. It may seem like too much, but trust the process—this is what gives the poke cake its delicious flavor.
Chill the Cake: Refrigerate the cake for at least 2 hours, allowing the gelatin to set and flavor the cake beautifully. The longer, the better.
Whip the Cream: After chilling, in a chilled bowl, whip 2 cups of cold heavy cream with 1 tablespoon granulated sugar, and a splash of vanilla until fluffy peaks form. This creates a light and creamy topping that balances the tart lime.
Frost the Cake: Spread the whipped cream over the chilled cake generously, ensuring it’s covered. For that extra festive touch, sprinkle with green sanding sugar, making it visually festive for St. Patrick’s Day!
Serve and Enjoy: Slice, serve, and watch as your guests delight in this light, tangy, and refreshing dessert. The creamy topping paired with the moist, flavorful cake is irresistible!

Storing & Reheating
To store leftovers, cover the cake tightly with plastic wrap and keep it in the refrigerator for up to 4 days. You can also freeze it for up to 3 months. To freeze, cut the cake into portions, place in airtight containers or freezer bags, and label them. When you’re ready to enjoy the cake, let it thaw in the fridge overnight. Reheating isn’t necessary, but a quick 10-second zap in the microwave can revive the cake if you prefer it warm. Just keep in mind, the texture might change slightly after freezing, but it remains delicious!
Chef’s Helpful Tips
- Avoid overmixing when combining flour and wet ingredients to maintain a fluffy cake texture.
- Use room temperature eggs for better emulsification into your batter.
- When making whipped cream, ensure your bowl and beaters are cold for quicker and fluffier results.
- If using low-fat alternatives, remember the cake’s texture might be slightly different but still enjoyable.
- Make-ahead magic: You can prepare the cake a day in advance and just whip the cream topping the day you plan to serve it.
A zesty lime poke cake isn’t just a dessert; it’s a delightful experience that brings people together. This cake’s vibrant flavor and cheerful appearance make it the perfect choice for any occasion, especially as a special treat for St. Patrick’s Day. Don’t hesitate to experiment with flavors or toppings; after all, the joy of baking lies in creativity. I hope you enjoy making it as much as I do!
