Pineapple Crumb Bars Ingredients
Let’s gather everything you need to make these delicious Pineapple Crumb Bars!
For the Crust and Topping
• All-Purpose Flour – Provides structure to the bars; substitute with gluten-free flour if needed.
• Unsweetened Shredded Coconut – Adds texture and a tropical flavor; can be replaced with chopped nuts if you have allergies.
• Granulated Sugar – Sweetens the mixture; try coconut sugar to enhance the tropical taste.
• Brown Sugar – Adds chewiness and depth; you can use more granulated sugar as a substitute.
• Baking Soda – A leavening agent for lift; ensure it’s fresh for the best results.
• Baking Powder – Works alongside baking soda for browning; always check dates for freshness.
• Salt – Brings balance to the sweetness of the bars.
• Unsalted Butter – Creates a firm, rich base; allow it to melt and cool for the right texture.
For the Filling
• Crushed Pineapple – The star ingredient that gives these bars their tropical flavor; ensure it’s well-drained.
• Cornstarch – Helps thicken the pineapple filling; you can omit it in some recipes, but it helps avoid sogginess.
• Vanilla Extract – Adds a warm note that beautifully complements the pineapple; coconut extract can boost the tropical flavor.
• Cinnamon – An optional spice that gives warmth and a comforting flavor; consider adding for an extra touch.
Step‑by‑Step Instructions for Pineapple Crumb Bars
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C) and grab an 8-inch square baking pan. Line the bottom and sides with parchment paper for easy removal later. This simple step ensures your Pineapple Crumb Bars bake evenly while preventing sticking, making the cutting process a breeze once they cool.
Step 2: Mix the Dry Ingredients
In a mixing bowl, combine 2 cups of all-purpose flour, 1 cup of shredded coconut, 1/2 cup of granulated sugar, 1/2 cup of brown sugar, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and a pinch of salt. Whisk these ingredients together until well blended, ensuring the mixture has a uniform texture. This is the foundation for both the crust and crumble topping.
Step 3: Incorporate the Butter
Melt 1 cup of unsalted butter and allow it to cool for a few minutes. Slowly pour the butter into the dry mixture while stirring gently with a spatula. Continue mixing until the mixture transforms into coarse crumbs. Set aside 1 cup of this crumb mixture for your topping later. The remaining crumbs will become the irresistible base for your Pineapple Crumb Bars.
Step 4: Form the Crust
Take the remaining crumb mixture and press it firmly into the bottom of the prepared baking pan. Use your fingers or the back of a measuring cup to pack it down evenly, ensuring it forms a solid crust. This should take about 2 minutes. Your crust is now ready to welcome the delightful pineapple filling!
Step 5: Prepare the Pineapple Filling
In a separate bowl, combine 2 cups of well-drained crushed pineapple, 1/4 cup of granulated sugar, 1 tablespoon of cornstarch, 1 teaspoon of vanilla extract, and a dash of cinnamon if desired. Stir the mixture until everything is well incorporated, making sure the cornstarch is fully dissolved. This luscious filling will bring a tropical flavor explosion to your bars.
Step 6: Assemble the Bars
Pour the pineapple filling evenly over the crust in the baking pan. Use a spatula to gently spread it out, ensuring every corner is filled. Once the filling is in place, it’s time to sprinkle the reserved crumb mixture on top, creating a delightful texture. This layer will turn perfectly golden as the Pineapple Crumb Bars bake.
Step 7: Bake
Carefully place the baking pan in the preheated oven and bake for 25 minutes. Keep an eye on the topping; it should turn a golden brown when finished. The aroma of baking pineapple and coconut will fill your kitchen, hinting at the delicious treat coming together.
Step 8: Cool and Slice
After baking, remove the pan from the oven and allow the bars to cool completely at room temperature. For the best texture, refrigerate for a few hours before slicing into squares. This cooling period helps the flavors meld beautifully, giving you the perfect slice of Pineapple Crumb Bars to enjoy!

Expert Tips for Pineapple Crumb Bars
• Drain Pineapple Juice: To prevent sogginess, ensure you drain the crushed pineapple thoroughly. Excess juice can compromise the texture of your bars.
• Cool the Butter: Always allow the melted butter to cool before mixing it with dry ingredients. Hot butter can create a greasy texture and alter the final outcome of your Pineapple Crumb Bars.
• Avoid Overbaking: Keep a close eye on your bars. Begin checking them around the 20-minute mark, as overbaking can lead to a dry crust.
• Measure Flour Correctly: Use the spoon-and-level method to measure flour. This helps avoid packing it down, which can make your bars dense rather than light and crumbly.
• Flavor Variation: Don’t hesitate to get creative! Try adding different fruits like blueberries or cherries to the filling for extra flavor.

What should I do if my crumb topping is too dry?
If your crumb topping appears too dry or crumbly, you can mix in a tiny bit of melted butter or a splash of milk to help bind it together. Remember, the texture should resemble coarse crumbs; it’s meant to sprinkle on easily but still hold together.
