Hawaiian guava cake is an iconic island dessert of soft, tender pink-tinted sponge layers soaked in sweet guava juice, filled and frosted with a light, billowy whipped cream frosting that is barely sweet and perfectly cool, finished with a glossy guava gel layer on top that sets into a jewel-bright pink surface that looks stunning and tastes intensely of fresh tropical guava. The cake is moist and delicate. The whipped cream is cloud-like and fresh. The guava flavor runs through every single layer from the sponge to the soak to the topping.

This is the cake that anyone who grew up in Hawaii or visited the islands knows immediately. It is sold in every bakery, every supermarket, and every family gathering from Oahu to Maui. Soft. Pink. Tropical. Unmistakable.

Twenty-five minutes to prep. Thirty-five minutes to bake. Time to cool and assemble. A cake that tastes like the islands and looks like nothing else on a dessert table.

Why You Will Love This Recipe

• Intensely tropical flavor. Guava juice in the sponge, guava soaked on the layers, and guava gel on top. Every bite is unmistakably, beautifully guava.
• The whipped cream frosting is light and fresh. No heavy buttercream. No dense ganache. Just billowy, lightly sweetened whipped cream that lets the guava flavor be the star.
• The pink color is completely natural. Guava juice gives the sponge and the gel their distinctive soft pink color without a drop of food coloring needed.
• It is a sheet cake format. No stacking. No difficult assembly. One rectangular pan, one flat top, one glossy gel layer. Simple and stunning.
• It can be made entirely ahead. Bake the cake. Assemble with the whipped cream. Pour the gel. Refrigerate overnight. Pull it out and serve. Nothing to do on the day.
• It is genuinely unlike any other cake. The combination of guava, whipped cream, and gelatin-set topping is entirely its own thing. Once you try it, there is no forgetting it.

Ingredients

For the Guava Sponge

• 2 cups (250g) all-purpose flour
• 2 teaspoons baking powder
• ½ teaspoon salt
• ¾ cup (170g) unsalted butter, softened to room temperature
• 1½ cups (300g) granulated sugar
• 4 large eggs, room temperature
• 1 cup (240ml) guava juice or guava nectar
• 1 teaspoon pure vanilla extract
• 2–3 drops pink or red food coloring (optional — deepens the natural pink from the guava)

For the Guava Soak

• ½ cup (120ml) guava juice or guava nectar
• 2 tablespoons sugar
• 1 tablespoon fresh lemon juice

For the Whipped Cream Frosting

• 2 cups (480ml) heavy whipping cream, very cold
• 3 tablespoons powdered sugar, sifted
• 1 teaspoon pure vanilla extract
• 1 tablespoon unflavored gelatin powder dissolved in 2 tablespoons cold water (stabilizes the cream so it holds its shape)

For the Guava Gel Topping

• 1½ cups (360ml) guava juice or guava nectar
• 3 tablespoons sugar
• 2 teaspoons unflavored gelatin powder
• 2 tablespoons cold water

For Finishing

• Fresh guava slices, if available
• Extra whipped cream piped around the border
• Edible flowers (optional)
• Extra pink color in the gel for a more vivid finish

Equipment Needed

• 9×13 inch (23×33 cm) baking pan
• Parchment paper
• Stand mixer or electric hand mixer
• Large mixing bowls
• Small saucepan for the gel
• Offset spatula for spreading whipped cream
• Wire rack for cooling
• Pastry brush for the soak

Instructions

Step 1: Preheat the oven to 175°C (350°F). Grease a 9×13-inch pan generously. Line with parchment paper, leaving an overhang on the long sides. Grease the parchment.

Step 2: Whisk flour, baking powder, and salt together in a bowl. Set aside.

Step 3: Beat softened butter and sugar in a stand mixer on medium-high for 4–5 minutes until very pale, light, and fluffy. Proper creaming is essential — this step creates the lift and tender crumb of the finished cake.

Step 4: Add eggs one at a time, beating for 30 seconds after each addition. Scrape down the bowl after every two eggs. Add vanilla extract with the last egg.

Step 5: Reduce to low speed. Add the flour mixture and guava juice alternately — flour, guava juice, flour, guava juice, flour — beginning and ending with flour. Mix only until just combined after each addition. Overmixing develops gluten and toughens the crumb.

Step 6: Add 2–3 drops of pink food coloring if using for a deeper color. Fold in gently.

Step 7: Pour the batter into the prepared pan. Smooth the top evenly. Bake for 30–35 minutes until a toothpick inserted in the center comes out with a few moist crumbs and the edges have pulled slightly from the pan.

Step 8: Cool in the pan for 15 minutes. Lift out using the parchment overhang and cool completely on a wire rack — at least 1 hour. The cake must be completely cool before the whipped cream goes on.

Step 9: Make the guava soak. Heat guava juice, sugar, and lemon juice in a small saucepan over medium heat until the sugar dissolves. Cool to room temperature. Using a pastry brush, soak the entire surface of the cooled cake with the guava mixture. Apply generously — the soak penetrates the sponge and deepens the guava flavor throughout every layer.

Step 10: Make the stabilized whipped cream. Sprinkle gelatin over 2 tablespoons of cold water in a small bowl. Let it bloom for 5 minutes. Microwave for 10 seconds until just melted and liquid. Cool to room temperature — it must not be hot when added to the cream.

Step 11: Whip the very cold heavy cream with powdered sugar and vanilla to soft peaks. With the mixer running, stream in the cooled liquid gelatin. Continue whipping to firm peaks. The stabilized whipped cream holds its shape for 24–48 hours in the fridge without weeping or deflating.

Step 12: Spread the whipped cream evenly over the soaked cake in a thick, smooth layer using an offset spatula. Smooth the top as flat as possible — the guava gel will be poured directly over it and needs a flat surface to set evenly.

Step 13: Refrigerate the frosted cake for 30 minutes until the whipped cream is firm and cold.

Step 14: Make the guava gel topping. Sprinkle gelatin over 2 tablespoons of cold water. Let bloom for 5 minutes. Heat guava juice and sugar in a small saucepan until the sugar dissolves and the juice is warm but not boiling. Remove from heat. Add the bloomed gelatin and stir until completely dissolved. Cool to room temperature — the gel must be completely cool before pouring, or it will melt the whipped cream beneath it.

Step 15: Pour the cooled gel slowly and evenly over the chilled whipped cream surface. It should pour in a thin, even layer and spread to the edges naturally. If it begins to set before spreading fully, tilt the pan gently to encourage it to the edges.

Step 16: Refrigerate for at least 2 hours until the gel is completely set and firm to the touch. Overnight refrigeration gives the cleanest, most perfectly set gel surface.

Step 17: Slice with a sharp knife dipped in hot water and wiped clean between cuts. The gel layer cuts cleanly when cold. Serve cold directly from the fridge.

Substitutes & Swaps

• Guava juice or nectar: Look for pure guava juice or Kern’s guava nectar, which is widely available and the traditional choice for this cake. Passion fruit juice gives a different but equally tropical result. Strawberry guava juice gives a slightly more floral, sweeter variation.
• Unflavored gelatin: Agar-agar works for a vegetarian or vegan gel — use half the quantity as agar sets firmer than gelatin. The texture is slightly different, but the visual result is identical.
• Heavy whipping cream: Full-fat coconut cream whipped cold works for a dairy-free version. It must be full-fat and refrigerated overnight before whipping. The flavor adds a subtle coconut note that pairs beautifully with the guava.
• All-purpose flour: Cake flour gives an even more delicate, tender crumb — use the same quantity. The texture is noticeably lighter with cake flour.
• Butter in the sponge: A neutral oil at ¾ cup gives a moister sponge that stays soft longer. The flavor is slightly less rich, but the crumb is excellent.

Variations

Strawberry Guava Cake

Use strawberry guava juice throughout — in the sponge, the soak, and the gel. The color deepens to a more vivid pink-red, and the flavor is slightly more floral and sweet than standard guava. Decorate with fresh strawberries around the border.

Passion Fruit Guava Cake

Replace half the guava juice in the gel topping with fresh passion fruit pulp, strained of seeds. The passion fruit adds tartness and complexity to the gel that makes the topping taste extraordinarily tropical.

Coconut Guava Cake

Replace the whole milk or water in the sponge batter with coconut milk. Add ½ cup of desiccated coconut to the batter. Toast extra coconut and press around the sides of the finished cake. The coconut and guava combination is classic Hawaiian.

Mini Guava Cakes

Bake the batter in a 24-cup muffin tin lined with paper liners. Bake at 175°C for 18–20 minutes. Pipe whipped cream on top of each cooled cupcake. Spoon a small amount of cooled gel over each one. Refrigerate to set. Individual portions perfect for parties.

Tips & Tricks

• Use guava nectar or pure guava juice — not guava cocktail. A guava cocktail is mostly water and sugar with very little actual guava. It produces a weak, pale result with almost no guava flavor. Pure guava nectar or juice gives the intensity of flavor and the pink color that this cake depends on.
• Cool the gel completely before pouring. This is the most critical step in the assembly. Warm gel melts the whipped cream beneath it on contact. The gel and the cream layer stay separate and beautiful only when the gel is poured completely cool, and the whipped cream beneath it is completely cold and firm. Both conditions must be met simultaneously.
• Stabilize the whipped cream. Plain whipped cream weeps and deflates within a few hours. The small amount of gelatin in the frosting keeps the whipped cream perfectly firm and fresh for 24–48 hours in the fridge. This step makes the difference between a cake that looks beautiful and one that looks like it sat too long.
• Soak the cake generously. The guava soak is what makes the sponge taste intensely of guava rather than just vaguely tropical. Brush it on in two passes — once immediately after lifting from the pan and once more before the whipped cream goes on. The sponge absorbs it completely, and the flavor deepens dramatically.
• Chill between every layer. Chill after the whipped cream goes on before the gel is poured. Chill after the gel is poured before slicing. Each chilling step sets the previous layer firmly and produces clean, distinct layers in every slice.
• Slice cold with a hot, clean knife. The gel layer is the most satisfying part to cut through — it should be firm and glossy and produce a clean edge. A hot knife dipped in water and wiped between every cut produces bakery-clean slices through every layer.

Frequently Asked Questions

Where do I find guava juice or guava nectar?

Kern’s guava nectar is the most widely available brand and is found in the Latin foods aisle or juice section of most large supermarkets. Asian grocery stores and Hawaiian specialty stores carry pure guava juice. Online retailers stock guava nectar in multipacks. In a pinch, a combination of passion fruit juice and a small amount of strawberry juice approximates the flavor and color.

Can I make this cake ahead of time?

Yes — this cake is actually better made the day before. Bake the sponge, apply the soak, frost with whipped cream, pour the gel, and refrigerate overnight. The soak penetrates more deeply, the whipped cream sets more firmly, and the gel becomes perfectly glossy. Pull from the fridge and slice the next day with no additional work required.

My gel did not set properly. What went wrong?

Either the gelatin did not bloom correctly, the gelatin was added to liquid that was too hot and deactivated it, or the gel was not given enough time to set. Always bloom gelatin in cold water first. Add it to warm — not boiling — liquid. Give the gel a full 2 hours minimum to set in the fridge, preferably overnight.

Can I make this cake gluten-free?

Yes. Replace the all-purpose flour with a 1-to-1 gluten-free flour blend. The texture is slightly denser, but the flavor is identical. All other ingredients in the recipe are naturally gluten-free.

The gel layer is sliding off the whipped cream when I slice. What happened?

The whipped cream was not cold and firm enough when the gel was poured, or the gel was slightly too warm when poured. Both cause the gel to sit on top of the cream rather than bonding with its surface. Ensure the whipped cream is refrigerated for at least 30 minutes before pouring and that the gel is completely cool and just beginning to thicken at the edges before it goes on.

Can I use whipped topping instead of making fresh whipped cream?

Store-bought stabilized whipped topping, such as Cool Whip, works and is actually commonly used in traditional Hawaiian bakery versions of this cake. Use 2 cups directly from the tub without any additional mixing. The flavor is less fresh than homemade whipped cream, but the texture and stability are excellent.
