Ingredients You’ll Need
- 1 cup unsalted butter, softened: Butter adds richness and moisture to the cake. Make sure it’s at room temperature for easy creaming.
- 2 1/2 cups all-purpose flour: This is the foundation of our cake. Use a flour with high protein content for the best results.
- 1/2 teaspoon baking powder: Helps the cake rise and creates that airy texture.
- 1/2 teaspoon baking soda: Works alongside the baking powder for a perfect puff.
- 1/2 teaspoon fine salt: Balances the sweetness for a well-rounded flavor.
- 1 1/4 cups buttermilk, well shaken: This adds tanginess and moisture. If you don’t have buttermilk, mix 1 cup of milk with 1 tablespoon of vinegar as a substitute.
- 2 teaspoons pure vanilla extract: Enhances the flavor profile, making it deliciously aromatic.
- 2 cups granulated sugar: Sweetens the cake and helps create a crumb that’s beautifully tender.
- 3 large eggs, lightly beaten: Provides structure and moisture to the cake.
- 3 ounces lime gelatin: Pack a punch of green flavor and ensures those delightful lime flavors seep into the cake.
- 2 cups heavy cream, cold: This will be whipped to top the cake; cold cream whips better.
- 1 tablespoon granulated sugar (for cream): Just a hint of sweetness to balance the richness of the cream.
- Green sanding sugar (for sprinkling): Not only adds sweetness but gives that festive touch!
How to Make St. Patricks Day Lime Poke Cake
Preheat the oven: Start by preheating your oven to 350°F. Greasing a 9×13-inch baking pan with butter allows your cake to slide out easily after baking.
Whisk dry ingredients: In a mixing bowl, whisk together the 2 1/2 cups of all-purpose flour, 1/2 teaspoon baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon fine salt. This step ensures even distribution of the leavening agents.
Mix wet ingredients: In a spouted measuring cup, combine 1 1/4 cups of buttermilk with 2 teaspoons of vanilla extract. This mixture adds moisture and flavor as well.
Cream butter and sugar: In a large mixing bowl, use a mixer at medium speed to cream together the softened 1 cup of unsalted butter and 2 cups of granulated sugar for about 5 minutes, or until the mixture is light and fluffy.
Incorporate eggs: Slowly add in the 3 lightly beaten eggs, mixing until fully incorporated. This builds the structure of your cake.
Combine ingredients: Alternately add the flour mixture and the buttermilk mixture to the butter mixture, starting and ending with the flour. Make sure to mix just until combined – overmixing can cause a dense cake.
Spread batter and bake: Pour the batter into your prepared baking pan, spreading it evenly. Bake it in the preheated oven for about 30 minutes, or until golden brown and a toothpick inserted in the center comes out clean. Let it cool in the pan for 30 minutes.
Poke holes in the cake: Once cooled, use a fork to poke holes about 1 inch apart all across the top of the cake. This is where the lime gelatin will seep in.
Prepare lime gelatin topping: In a bowl, dissolve the 3 ounces of lime gelatin in 1 cup of boiling water, stirring until fully dissolved. Add 1/2 cup of cold water to cool it down. Pour this mixture evenly over the poked cake, letting it sink into the holes.
Chill the cake: Cover with plastic wrap and refrigerate the cake for at least 2 hours. This allows the flavors to meld and settle beautifully.
Whip the cream: Using a chilled mixing bowl, whip 2 cups of cold heavy cream with the 1 tablespoon of granulated sugar until soft peaks form. This fluffy topping adds a rich texture on top of the cake that pairs perfectly with the tartness of lime.
Top and serve: Spread the whipped cream over the chilled cake, finishing off with a sprinkling of green sanding sugar for that festive touch. Slice, serve, and watch your guests light up with joy!

Storing & Reheating
Store any leftover cake in an airtight container at room temperature for up to 2 days. If you prefer to keep it longer, refrigerate for up to 5 days. You can freeze the cake for up to 3 months; wrap slices tightly in plastic wrap before placing them in a freezer-safe container. When ready to enjoy, thaw overnight in the refrigerator and serve chilled. Note that while freezing won’t drastically change the cake, the texture might become slightly denser, so refreshing it with a new layer of whipped cream can brighten it up.
Chef’s Helpful Tips
- Make sure your ingredients are at room temperature for better mixing and texture.
- Keep a close eye on your baking time; an overbaked cake can be dry, while an underbaked one will collapse.
- If the cake sinks slightly in the center, it may have been underbaked. A flat cake can still taste delicious!
- Try experimenting with flavored gelatin, like raspberry or lemon, for a fun twist.
- Don’t skip the chilling time; it’s crucial for the flavors to fully develop and meld.
The refreshing zesty flavor of the St. Patricks Day Lime Poke Cake not only celebrates the holiday but also brings joy to anyone who enjoys it. By following this simple recipe, you’ll craft a dessert that brightens any table and brings smiles to every gathering. Don’t hesitate to add your unique twist – the beauty of baking lies in experimentation and personalization.
