Ingredients You’ll Need
1 cup unsalted butter, softened: This gives your cake an incredibly rich and moist texture. Make sure it’s at room temperature for easy creaming.
2 1/2 cups all-purpose flour: Essential for structure, this flour ensures your cake has the right density without being too heavy.
1/2 teaspoon baking powder: This helps your cake rise beautifully.
1/2 teaspoon baking soda: Works alongside the baking powder to ensure a lighter texture.
1/2 teaspoon fine salt: Enhances flavor throughout the cake.
1 1/4 cups buttermilk, well shaken: Tenderizes the cake and adds delightful moisture. Whole milk with a splash of vinegar can be an easy substitute if needed.
2 teaspoons pure vanilla extract: Adds a warm note of sweetness that balances the zing of lime.
2 cups granulated sugar: Sweetens the cake perfectly while creating a light, fluffy texture.
3 large eggs, lightly beaten: These bind the ingredients together and add richness.
3 ounces lime gelatin: This contributes the signature lime flavor that’s unmistakable in the poke cake.
2 cups heavy cream, cold: Whipped into clouds of deliciousness for frosting the cake.
1 tablespoon granulated sugar (for cream): Sweetens the whipped cream beautifully without overpowering the lime flavor.
Green sanding sugar (for sprinkling): Just for fun! A little sprinkle on top adds a touch of festivity.
How to Make St. Patricks Day Lime Poke Cake
Preheat & Prepare: Start by preheating your oven to 350°F (175°C) and grease a 9×13-inch baking pan with a bit of unsalted butter or nonstick spray. This will prevent your cake from sticking, ensuring a clean release that makes serving easier.
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 helps to evenly distribute the leavening agents and salt, setting a solid foundation for your cake.
Mix Wet Ingredients: In a spouted measuring cup, combine 1 1/4 cups buttermilk with 2 teaspoons pure vanilla extract. Give it a little shake to mix together; then set aside.
Cream Butter & Sugar: In a large mixing bowl, cream together 1 cup softened unsalted butter and 2 cups granulated sugar at medium speed for about 5 minutes until the mixture is fluffy and pale. This step is vital for airy, light cake—so don’t rush it!
Incorporate Eggs: Slowly add in the lightly beaten 3 eggs, mixing on low until just combined. This helps to maintain that fluffy texture.
Combine Dry & Wet: Alternately add the dry flour mixture and the buttermilk mixture to the butter mixture, starting and ending with the flour. Mix until combined but do not overmix, as that can toughen the cake.
Bake the Cake: Pour your lovely batter into the prepared pan, spreading it evenly. Bake in your preheated oven for approximately 30 minutes, or until the edges are golden, and a toothpick inserted comes out clean. Allow the cake to cool in the pan for about 30 minutes.
Poke Holes: Using a fork, gently poke holes about 1 inch apart all over the top of your slightly cooled cake. These holes are what will make your cake a “poke” cake, allowing the gelatin to soak in and flavor the cake.
Prepare Gelatin Mixture: In a bowl, dissolve 3 ounces of lime gelatin in 1 cup of boiling water. Stir until completely dissolved, then add in 1/2 cup cold water for a quick cool down.
Soak the Cake: Pour the gelatin mixture evenly over the poked holes in the cake, allowing it to absorb into the cake. This will infuse the moist layers with a vibrant lime flavor.
Chill: Refrigerate the cake for at least 2 hours so it can soak up all the yumminess from the gelatin and firm up.
Whip Cream: In a chilled mixing bowl, whip 2 cups of cold heavy cream with 1 tablespoon granulated sugar until it reaches soft peaks. You can also add a splash of vanilla for extra flavor!
Frost the Cake: Spread the whipped cream over the chilled cake, creating smooth waves of fluff.
Sprinkle: Lastly, lightly sprinkle green sanding sugar over the top for that festive touch. This is where the fun really shines!

Storing & Reheating
To keep your St. Patricks Day Lime Poke Cake tasty and fresh, store it in the refrigerator, preferably in an airtight container. It will stay delicious for about 2-3 days. If you wish to store it longer, it can be frozen for up to 3 months. When ready to enjoy, thaw the cake in the refrigerator overnight for the best texture. Due to the whipped cream frosting, it’s best enjoyed within the first few days for optimal creaminess.
