1-First Step: Mix the cake batter. Start by preheating your oven based on the directions on the cake mix box, since baking times can vary a little by brand. In a mixing bowl, combine the 1 strawberry cake mix, 1 1/3 cups guava nectar or guava juice, 3 eggs, and 1/3 cup coconut oil. Stir until everything is well combined and the batter looks smooth. This step is where the tropical flavor starts to come alive. The guava juice gives the batter a fruity note, while the coconut oil adds moisture and a soft crumb. If you want a lighter result, you can use liquid coconut oil or room temperature coconut oil, whichever is easier for you.

2-Second Step: Bake the cake. Pour the batter into a greased 9×13-inch baking dish. Bake according to the cake mix package directions until the cake is done in the center. Most cakes in this style bake in about 25 minutes, but always check your pan and oven since every kitchen runs a little differently. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, the cake is ready. This is one of the best tips for a guava cake recipe because the layers only work well when the base is fully baked and not soggy.

3-Third Step: Make the cream cheese layer. While the cake bakes or cools, place the softened 8 ounces cream cheese in a medium bowl and beat it until fluffy. Add 1/3 cup sugar and 1 teaspoon vanilla, then mix until smooth. Fold in the 8 ounces thawed whipped topping gently so the mixture stays light and airy. For the best texture, use room temperature cream cheese. Cold cream cheese can leave lumps, and that makes spreading harder later. Once the mixture is ready, refrigerate it until you are ready to assemble the cake. A chilled cream layer holds its shape better and tastes refreshing against the sweet guava topping.

4-Fourth Step: Cook the guava glaze. Now make the topping. In a saucepan, bring 2 cups guava nectar or guava juice and 1/2 cup sugar to a boil. In a small bowl, mix 1/4 cup cornstarch with 3 tablespoons water to form a slurry, then pour it into the boiling guava mixture. Boil for one minute while stirring constantly. The mixture should thicken into a glossy gel. If it looks too thin, let it cook a little longer, stirring the whole time. This is the part that gives the dessert its signature shiny finish, so do not rush it. Once thickened, remove it from the heat and let it cool completely before spreading.

5-Fifth Step: Cool the cake fully. When the cake comes out of the oven, let it cool completely in the pan. This matters a lot. If you add the cream cheese layer while the cake is warm, the topping can melt and slide around. A fully cooled base makes the whole dessert cleaner and easier to serve. For busy parents or working professionals, this is a good place to pause. You can bake the cake earlier in the day, then finish the layers once the cake has cooled. That makes this hawaiian guava cake recipe very practical for weeknights and weekend parties.

6-Sixth Step: Add the cream layer. Spread the cream cheese mixture evenly over the cooled cake. Use an offset spatula or the back of a spoon to smooth it right to the edges. Try to keep the layer even so every slice gets the same creamy bite. If you want a lighter version, you can spread the topping a little thinner, but the classic version works best with a full creamy layer. That sweet and tangy middle is what makes this guava cake recipe stand out from other sheet cakes.

7-Seventh Step: Add the guava topping. Carefully spread the cooled guava gel over the cream cheese layer. Work slowly so the cream layer stays in place. If you like a neat look, spoon the glaze onto the center first, then gently move it outward. The guava topping should be cool but still spreadable. If it thickens too much before you use it, warm it very gently for a few seconds and stir again. The goal is a smooth top that shines and settles nicely.

8-Eighth Step: Chill until set. Refrigerate the cake until fully set. This usually takes at least a couple of hours, though longer chilling makes cleaner slices. The cold time helps the cream layer firm up and gives the glaze time to hold its shape. For the prettiest slices, chill the cake overnight if you can. That makes serving much easier, especially for parties or potlucks. It also gives the flavors time to blend together, which makes the cake taste even better.

9-Ninth Step: Slice and serve. Once the cake is set, cut it into 12 pieces and serve cold. Garnish with fresh guava slices or shredded coconut if you want a pretty finish. The cake already has a lovely pink color, so even a simple garnish looks special. This is a great dessert for guests who like fruity sweets, and it is also a fun recipe to make with kids or beginner bakers. The final result is creamy, fruity, and soft, with just enough tropical flavor to feel like a mini vacation on a plate.
