Ingredients and Variations

Key Ingredients

Here’s what you’ll need to make this citrusy Key Lime Poke Cake. Exact measurements are provided later in the recipe card.

• Yellow Cake Mix: A convenient base for a soft, buttery cake. Any standard 15.25-ounce box will work.
• Water, Vegetable Oil, Eggs: The classic trio to bring the cake mix together, giving it moisture and structure.
• Lime-Flavored Gelatin Mix: Adds a bright lime color and a burst of sweet citrus flavor that soaks into the cake.
• Key Lime Juice: Tart and slightly floral. Bottled key lime juice works well, or you can squeeze fresh key limes.
• White Sugar: Sweetens the lime filling and balances the tanginess.
• Cornstarch: Helps thicken the lime filling so it seeps into the cake without making it soggy.
• Lime Zest: Adds a fragrant, fresh citrus aroma. Grate only the outer green layer.
• Butter: Gives the lime filling a rich, smooth finish.
• Green Food Coloring (Optional): Enhances the cake’s vibrant lime appearance.
• Whipped Topping: A light, creamy layer to finish the cake. You can use homemade whipped cream or store-bought.

Variations for Key Lime Poke Cake

• Fresh Whipped Cream: Swap whipped topping with freshly whipped cream for a homemade touch.
• Graham Cracker Crumbs: Sprinkle on top for a hint of key lime pie flavor.
• Extra Zest: Stir more lime zest into the whipped topping for added citrus fragrance.
• Cream Cheese Frosting: Replace whipped topping with a light cream cheese frosting for a tangy twist.
• Lemon-Lime Version: Mix lemon and lime juice for a brighter citrus blend.
• No Food Coloring: Skip the green dye if you prefer a natural, pale lime hue.

Step-by-Step Instructions

1. Prepare the Cake

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with oil or butter.
2. In a large bowl, combine yellow cake mix, water, vegetable oil, and eggs.
3. Mix according to the package instructions, usually about 2 minutes on medium speed, until smooth.
4. Pour the batter into the prepared baking dish and smooth the top.
5. Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
6. Let the cake cool for about 10 minutes in the pan.

2. Poke the Cake

1. Once the cake is slightly cooled, use the handle of a wooden spoon, a skewer, or a fork to poke holes all over the cake, about an inch apart.
2. Make sure the holes go about halfway through the cake to let the filling soak in.

3. Prepare the Lime Filling

1. In a small saucepan, combine:
   • 1 package lime-flavored gelatin mix
   • 1 cup key lime juice
   • ¾ cup white sugar
   • 1 tablespoon cornstarch
2. Whisk the mixture over medium heat until the sugar and gelatin dissolve. Continue stirring for 3 to 5 minutes, until it slightly thickens.
3. Add 2 tablespoons butter and lime zest. Stir until the butter melts and the mixture is smooth.
4. Optional: Add a few drops of green food coloring for a vibrant lime color.

4. Pour and Chill

1. Slowly pour the warm lime filling over the cake, letting it seep into the holes.
2. Gently tap the pan on the counter to help the filling settle into the cake.
3. Let the cake cool to room temperature, then cover and refrigerate for at least 2 hours (or overnight) to allow the flavors to develop.

5. Add Whipped Topping

1. Once the cake is fully chilled, spread the whipped topping evenly over the surface.
2. For extra flavor and color, sprinkle more lime zest on top or add a few thin lime slices as garnish.
