Kitchen Tools You’ll Need
- Mixing bowls
- Whisk
- Baking pan (9×13 inch)
- Spatula
Ingredients
- 2 cups all-purpose flour (provides structure)
- 1 cup granulated sugar (adds sweetness and moisture)
- 1/2 cup unsalted butter, melted (enhances richness)
- 2 large eggs (binds the ingredients)
- 1 tsp vanilla extract (imparts flavor)
- 1 tsp baking powder (helps the batter rise)
- 1/2 tsp baking soda (aids in leavening)
- 1/2 tsp salt (balances sweetness)
- 1 can (20 oz) crushed pineapple, well-drained (adds moisture and flavor)

How to Make Hawaiian Pineapple Cake Bars for Parties
Step 1. Begin by preheating your oven to the appropriate temperature for baking. This step is crucial as it ensures even cooking throughout the cake bars. While the oven heats, gather your ingredients to keep the process streamlined.
Step 2. In a mixing bowl, combine the flour, baking powder, baking soda, and salt. Whisk these dry ingredients together until they’re well blended. This helps ensure even distribution of the leavening agents, which is key to the cake rising properly.
Step 3. In another bowl, mix together the melted butter and granulated sugar. Stir them until they form a smooth mixture. This process helps to dissolve the sugar into the butter and creates a base that contributes to the final texture.
Step 4. Add the eggs and vanilla extract to the butter-sugar mixture. Whisk everything together until the mixture is smooth and well-combined. The eggs contribute to the structure and moistness, while the vanilla adds a welcoming aroma and taste.
Step 5. Gradually incorporate the flour mixture into the wet ingredients. Stir gently until just combined, being careful not to overmix. The batter will start to come together, and it’s important to keep a slightly lumpy texture for the best results.
Step 6. Fold in the well-drained crushed pineapple. Gently combine it with the batter until evenly distributed. This adds not only moisture but also a bright, fruity flavor that enhances the overall taste of the cake bars.
Step 7. Pour the batter into a greased 9×13 inch baking pan. Use a spatula to spread it evenly across the bottom. This ensures that the cake bakes uniformly, with each corner getting the same treatment as the center.
Step 8. Place the pan in the preheated oven and bake until the cake is golden brown. A toothpick inserted into the center should come out clean to indicate that it’s done. Keep an eye on it as baking times can vary slightly.
Step 9. Once baked, remove the cake bars from the oven and let them cool in the pan. This resting period allows the bars to set properly, making them easier to cut later on. A cool period also helps preserve their texture.
Step 10. After cooling, cut the cake into bars and serve. They can be enjoyed warm or at room temperature, providing flexibility for your serving options. Enjoy the delightful flavors and textures of your homemade Hawaiian Pineapple Cake Bars!

Pro Tips for Best Results
- Ensure Proper Drainage: Make sure to drain the crushed pineapple thoroughly to prevent adding excess moisture to the batter. Too much liquid can result in a soggy texture.
- Don’t Overmix: When combining the flour mixture with the wet ingredients, mix just until incorporated to keep the cake bars light and tender.
- Use Fresh Ingredients: Always check that your baking powder and soda are fresh, as stale leavening agents can affect the rise of the cake.
- Cool Completely: Allow the bars to cool fully before cutting to maintain their shape and texture.
- Taste Variations: Consider experimenting with a sprinkle of coconut or pecans on top of the batter for an added texture contrast.
Common Mistakes to Avoid
- Not Draining Pineapple Well: Failing to strain the crushed pineapple properly can make the bars too moist, leading to a dense texture. Make sure to press the pineapple against a strainer to remove excess juice.
- Overmixing the Batter: Overmixing after adding the flour can cause the cake to become tough. Mix until just combined to keep the texture light and airy.
- Incorrect Oven Temperature: If your oven isn’t at the right temperature, the bars might not bake evenly. Use an oven thermometer to ensure accuracy.
- Cutting While Warm: Cutting the bars too soon can lead to crumbling and tearing. Allow them to cool for at least 30 minutes in the pan before slicing.
- Not Measuring Ingredients Accurately: Baking is a precise science. Make sure to measure your ingredients accurately for the best results.
- Skipping the Cooling Step: Cutting into the bars while they’re still warm may cause them to fall apart. Letting them cool allows for a firmer structure.
Variations & Substitutions
For a little twist, consider adding shredded coconut or chopped nuts to the batter for added texture. These ingredients blend well with the pineapple flavor. You could also opt for a cream cheese frosting on top for added richness, should you desire a different finish.
Storage & Reheating
Store your Hawaiian Pineapple Cake Bars at room temperature in an airtight container for up to three days. For longer storage, keep them in the refrigerator for up to a week. If you want to freeze them, wrap the bars individually in plastic wrap and then place them in a freezer-safe bag for up to three months. When reheating, place them in the microwave for a few seconds to restore their moisture without making them too soft.
