The Ultimate Coconut Lime Poke Cake: A Tropical Vacation in Every Bite
By Jason Griffith | ChefManiac.com
If you are looking for the perfect dessert to transport your taste buds to a white-sand beach, look no further. This Coconut Lime Poke Cake is the ultimate tropical treat—balancing the zesty, bright notes of fresh lime with the creamy, sweet indulgence of coconut.
Poke cakes are a retro classic for a reason: by poking holes into the cake and pouring a delicious liquid over the top, you ensure that every single bite is incredibly moist and infused with flavor. This version is light enough for a summer barbecue but decadent enough to be the star of any holiday dinner party.
Why I Love This Recipe
I am a huge fan of “make-ahead” desserts. I love this recipe because it actually tastes better the longer it sits. Letting the cake chill in the fridge allows the coconut milk and lime juice to fully soak into the crumb, creating a texture that is almost like a tropical Tres Leches.
It’s also incredibly easy to scale up for big families. Whether you’re serving this after a spicy meal like this Mexican Chicken and Rice Casserole or looking for a sweet follow-up to a savory Crockpot Nacho Dip, this cake provides that perfect, refreshing palate cleanser.
Ingredients
For the Cake:
- White Cake Mix: 1 box (plus ingredients called for on the box, usually water, oil, and egg whites)
- Lime Zest: 1 tbsp (freshly grated)
For the “Poke” Filling:
- Sweetened Condensed Milk: 1 can (14 oz)
- Coconut Milk: 1/2 cup (Full-fat canned coconut milk is best)
- Lime Juice: 1/4 cup (Freshly squeezed)
For the Topping:
- Whipped Topping: 1 container (8 oz, thawed) or fresh whipped cream
- Shredded Coconut: 1/2 cup (Toasted or sweetened)
- Lime Slices: For garnish
Swaps and Notes
- Cake Mix: If you prefer a more “homemade” feel, you can use a classic yellow cake mix for a richer, more buttery base.
- Toasted Coconut: I highly recommend toasting your coconut in a dry skillet for 2-3 minutes until golden; it adds a sophisticated crunch and a deeper nutty flavor.
- Extra Lime: If you really love citrus, add an extra teaspoon of lime juice to the whipped topping before spreading it over the cake.
Step-by-Step Instructions
1. Bake the Base
Prepare the white cake mix according to the box instructions, stirring in the lime zest before pouring the batter into a greased 9×13-inch baking pan. Bake as directed and let it cool for about 10–15 minutes.
2. The “Poke” Step
Using the handle of a wooden spoon or a large straw, poke holes all over the top of the warm cake. Space them about an inch apart to ensure the filling reaches every corner.
3. Mix the Tropical Glaze
In a medium bowl, whisk together the sweetened condensed milk, coconut milk, and lime juice until smooth.
4. The Pour
Slowly pour the glaze over the cake, making sure it seeps down into all the holes. Spread any excess glaze across the surface with a spatula.
5. Chill and Set
This is the most important part! Cover the cake and refrigerate for at least 4 hours, or preferably overnight. This gives the cake time to absorb the liquids and firm up.
6. Top and Serve
Once chilled, spread the whipped topping evenly over the cake. Sprinkle generously with shredded coconut and garnish with lime zest or thin lime slices.
Tips for Success
- Use Fresh Limes: Bottled lime juice simply doesn’t have the same floral punch as fresh limes. Since you need the zest anyway, go for the real thing!
- Poke While Warm: Make sure the cake is still slightly warm when you poke the holes and pour the glaze; it helps the cake absorb the moisture more effectively.
- Full-Fat Coconut Milk: Don’t use the refrigerated carton coconut milk used for cereal. The canned version is thicker and adds the necessary richness.
Serving Suggestions and Pairings
This cake is a refreshing end to a savory feast. I love serving it at parties alongside these Totchos for a fun “salty and sweet” menu. It also pairs beautifully with a One Pan Breakfast Bake for a fancy Sunday brunch. If you’re feeling extra tropical, serve it with a chilled glass of sparkling water or a light mojito.

Storage and Leftover Tips
Keep the cake covered and refrigerated. It will stay delicious for up to 4–5 days. In fact, many people find it tastes even better on day two! I don’t recommend freezing this cake once it’s been topped with whipped cream, as the texture of the whipped topping can change when thawed.
