How to Make St. Patricks Day Lime Poke Cake
Preheat Oven: Start by preheating your oven to 350°F (175°C). Grease and butter a 9×13-inch baking pan thoroughly; this will prevent sticking and ensure lovely edges.
Mix Dry Ingredients: In a bowl, whisk together 2 ½ cups all-purpose flour, ½ teaspoon baking powder, ½ teaspoon baking soda, and ½ teaspoon fine salt. This combination creates a perfect foundation for your cake.
Combine Wet Ingredients: In a spouted measuring cup, mix 1 ¼ cups buttermilk and 2 teaspoons pure vanilla extract until combined.
Cream Butter and Sugar: In a large mixing bowl, cream 1 cup softened unsalted butter and 2 cups granulated sugar using an electric mixer at medium speed for about 5 minutes, or until the mixture is fluffy and light in color.
Add Eggs: Gradually incorporate 3 lightly beaten large eggs into the butter mixture. Mix until combined smoothly. This step ensures the batter is light and airy.
Alternate Mixing: Slowly add the flour mixture and buttermilk mixture, beginning and ending with the flour. Mix just until everything is well incorporated, being careful not to overmix; this will help create a light texture.
Bake the Cake: Spread the batter evenly into the prepared pan. Bake for about 30 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean. Let it cool in the pan for 30 minutes while you prepare the next steps.
Poke Holes: Using a fork, poke holes in the cake about 1 inch apart. Make sure to poke down deep enough but not all the way through to the bottom.
Prepare Gelatin: In a small bowl, dissolve 3 ounces of lime gelatin in 1 cup of boiling water. Stir until fully dissolved before adding ½ cup of cold water, mixing well.
Pour Over the Cake: Gently pour the gelatin mixture over the poked cake, allowing it to seep into the holes. This adds a burst of flavor and moisture.
Chill: Refrigerate the cake for at least 2 hours, allowing the gelatin to set and infuse the flavors throughout the cake.
Whip Cream: In a chilled mixing bowl, whip 2 cups of cold heavy cream with 1 tablespoon granulated sugar and a splash of vanilla until soft peaks form. This will be your light, fluffy topping.
Spread on Cake: Once chilled, spread the whipped cream over the top of the cake evenly. Finish it off with a sprinkle of green sanding sugar for that festive touch.

Storing & Reheating
To store your lime poke cake, cover it tightly and refrigerate for up to 5 days. If you’d like to keep it longer, consider freezing it. Slice the cake into portions, wrap each piece in plastic wrap, and place it in an airtight container. The cake can be frozen for up to three months. When you’re ready to enjoy, simply thaw in the refrigerator overnight — just note that the texture may be a little softer after freezing, which is still delicious!
Chef’s Helpful Tips
- Make sure your butter is softened but not melted to achieve the perfect creamy texture when mixing with sugar.
- For an added citrusy kick, consider zesting a lime into the batter or topping for extra flavor.
- If the whipped cream isn’t holding its shape, try adding a tablespoon of powdered sugar for stability.
- Don’t skip the chilling step; letting the cake sit for a while is essential to allow the flavors to meld and the textures to set beautifully.
- If you want to reduce the sweetness, you can cut back slightly on the sugar in the whipped cream.
The zesty flavor combined with the creamy topping makes this cake an unforgettable treat perfect for celebrating St. Patrick’s Day. I encourage you to experiment with the flavors and even incorporate your favorite elements. Enjoy this festive dessert and the smiles it brings to your table!
