Before you get started, let’s gather everything you need to build this luscious Key Lime Poke Cake.
Let’s walk through how to transform simple ingredients into a show-stopping poke cake. You’ll bake a classic yellow cake, poke it full of holes for maximum flavor infusion, then drench it in a sweet-and-tart lime mixture before topping with whipped cream and graham cracker crumbs. Follow these steps to guarantee every slice delivers that dreamy, citrusy punch.
1. Preheat the oven to 350°F and grease a 9x13-inch baking pan with non-stick spray or a light coat of butter, making sure every corner is covered to prevent sticking.
2. Combine the batter: In a large bowl, add the cake mix, 3 eggs, vegetable oil, and water. Use a whisk or electric mixer on low speed to blend until a smooth, lump-free batter forms.
3. Bake the cake: Pour the batter into the prepared pan, smoothing the top. Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
4. Cool and poke: Let the cake rest for about 10 minutes—warm but not hot—then use the handle of a wooden spoon to poke holes evenly across the surface, about 1 inch apart.
5. Make the lime soak: In a medium bowl, whisk together sweetened condensed milk, key lime juice, and lime zest until fully combined and smooth.
6. Soak the cake: Slowly pour the lime mixture over the warm cake, letting it drip into each hole so the liquid sinks deep into the crumb.
7. Chill: Refrigerate the cake for at least 2 hours so the lime mixture can fully absorb and the filling sets.
8. Top with whipped cream: Spread the thawed whipped topping evenly over the chilled cake to create a cloud-like layer.
9. Add graham crackers: Sprinkle crushed graham crackers over the whipped topping for a buttery crunch.
10. Serve: Cut into squares and enjoy each slice chilled for the best texture and flavor.

To make sure every slice of your Key Lime Poke Cake stays as delightful as the first, storing it properly is a must. These storage methods will help maintain the moist, tangy filling and the fluffy whipped topping so you can enjoy leftovers for days.
Here are answers to your most pressing questions about Key Lime Poke Cake:
It takes about 15 minutes of active prep to mix the batter and ingredients, 25–30 minutes to bake, 10 minutes to cool before poking holes and adding the lime mixture, and at least 2 hours of refrigeration for chilling and setting. In total, you should allow roughly 3 hours from start to finish.
Yes, although key limes have a uniquely bright, floral aroma. If using regular Persian limes, you may want to increase the zest by an extra teaspoon to boost citrus flavor. The tartness will be slightly milder, so taste and adjust the lime juice amount if needed.
Poking holes when the cake is warm ensures it’s sturdy enough to hold its shape yet soft enough for the sweetened condensed milk and lime mixture to sink in evenly. If the cake is too hot, it can collapse; if it’s too cool, the mixture will pool on top instead of infusing the crumb.
Refrigeration allows the sweetened condensed milk, key lime juice, and zest mixture to fully absorb into the cake, creating a moist, tangy layer throughout. Chilling also helps the whipped topping set smoothly, making it easier to achieve clean, even slices.
Store any leftovers covered in plastic wrap or in an airtight container in the refrigerator for up to 3 days. To serve, let slices sit at room temperature for 5–10 minutes so they soften slightly and the whipped topping regains its creamy texture.
Absolutely. You can bake the cake, poke the holes, and pour in the lime mixture up to a day ahead. Keep it covered in the refrigerator, then just before serving spread on the whipped topping and sprinkle the graham cracker crumbs to maintain freshness and crunch.
