Golden pineapple goodness rests on a crumbly butter crust in these tantalizing island-inspired squares. Each mouthful delivers just the right mix of tangy fruit flavor against a rich, soft base that disappears on your tongue. These squares bring island vibes to your home with surprisingly little work—the quick press-down crust and easy-mix topping come together fast, making something way better than you'd expect from such basic ingredients. The difference between the soft shortbread bottom and the sticky, fruit-packed top makes a texture heaven that'll have you reaching for seconds.
I first whipped these squares up for my kid's Hawaiian party last summer. I thought they'd be nice, but wasn't ready for the crowd that swarmed the sweet table or all the folks asking how I made them. Even my wife's dad, who always says he doesn't go for 'fruit desserts,' was spotted grabbing extras throughout the night.
Sunny Essential Ingredients
- All-purpose flour (1¾ cups total): Makes the base for both the shortbread bottom and helps thicken the topping; scoop into measuring cups and level off for best results
- Granulated sugar (1½ cups total): Adds sweetness while helping both layers hold their shape; finer sugar mixes in better if you've got it
- Salt (¼ teaspoon): Brings out the butter flavor in the crust while cutting the sweetness; fine sea salt works better than regular table salt
- Unsalted butter (¾ cup, cold and diced): Gives that rich, melt-in-your-mouth feel that makes shortbread so good; fancy butter with more fat will make it even better
- Crushed pineapple (1 cup, drained well): Adds that sunny tropical kick and juiciness; fresh pineapple mashed at home tastes amazing, but canned does the job too
- Large eggs (2): Hold the filling together and give it structure; eggs at room temp mix in more easily
- Baking powder (½ teaspoon): Adds a tiny bit of rise to the filling without making it too cakey; brands without aluminum taste better
- Vanilla extract (1 teaspoon): Works with the pineapple to make everything taste better; real extract beats fake stuff any day
- Powdered sugar (for sprinkling): Makes the finished bars look pretty and adds a touch more sweetness; shake it through a strainer for the nicest look
How To Make Them
- Get Your Oven Ready:
- Heat oven to 350°F (175°C) with the rack in the middle so heat spreads evenly. Put parchment in a 9×13-inch pan with extra hanging over the sides so you can lift the bars out later. This makes cutting and serving way easier.
- Make The Crust Mixture:
- Mix 1½ cups flour, ½ cup sugar, and salt in a bowl with a quick stir to get everything mixed. Drop in cold butter chunks and cut them in using a pastry tool, two knives, or just your fingers until it looks like rough crumbs with some small butter bits still showing. This makes the crust nice and flaky.
- Form The Bottom Layer:
- Dump the crumbs into your prepared pan, spread them out and press down firmly using a measuring cup bottom or glass to make it flat and solid. The pressing helps make that dense but tender texture. Poke the surface a few times with a fork so steam can escape while baking.
- Pre-Bake The Crust:
- Bake the crust for just 15 minutes until the edges start to look golden but the middle stays pale. This half-baking lets the crust firm up enough to hold the wet filling without getting soggy while finishing cooking later.
- Get The Pineapple Ready:
- Drain your crushed pineapple really well, gently pressing it in a strainer to get rid of extra juice without smashing the fruit. Too much liquid will make your filling runny, but you want some moisture for a juicy texture.
- Mix The Filling:
- In another bowl, beat eggs and the remaining 1 cup sugar until it's smooth and slightly thick, about 2 minutes. This makes the custard base for your filling. Stir in ¼ cup flour and baking powder until you don't see any dry spots. Add vanilla and fold in your drained pineapple until it's all mixed in.
- Put It All Together:
- Pour the pineapple mix evenly over your partly baked crust, using a spatula to spread it to the corners and make it level. The filling should look pretty wet right now—it'll set as it bakes.
- Finish Baking:
- Put the pan back in the oven and bake for 25-30 minutes until the edges look set and golden while the middle still jiggles slightly. The filling will firm up as it cools. Don't overbake or the filling gets tough instead of gooey.
- Let It Cool:
- Let the bars cool completely in the pan on a wire rack, which might take 2-3 hours. This waiting gives you perfectly set bars that cut cleanly. For even neater squares, chill for 1 hour after they reach room temperature.

My grandma always said fruit desserts need a little salt to really pop. 'It brings the flavor to life,' she'd tell me while tossing that important pinch into her famous pineapple upside-down cake. She taught me you can't rush cooling fruit bars—a lesson I found out the hard way after once cutting too early and ending up with a tasty but messy pineapple puddle. These bars follow her wisdom with their awesome mix of flavors and textures.
Ways To Serve
These easy-going bars work for all kinds of events and serving ideas. For casual get-togethers, just stack them on a plain platter with some fresh mint leaves for a pop of color. Dress them up for dinner parties by serving single bars with coconut whipped cream and a light sprinkling of toasted coconut. In hot weather, try them with vanilla ice cream and a drizzle of warm caramel for a fancy treat. Make a tropical dessert spread by putting bars next to fresh pineapple chunks, coconut cookies, and chocolate-covered dried mango pieces.
Fun Twists To Try
Switch up this flexible recipe to make exciting flavor combos while keeping that tropical vibe. Coconut fans can toss ½ cup toasted coconut shreds into the filling and swap coconut extract for the vanilla. Make a piña colada version by adding 2 tablespoons of rum extract to your mix. For a warm kick, add ¼ teaspoon of ground cardamom or ginger to the filling. Citrus lovers can mix in 1 tablespoon of lime zest for a pineapple-lime combo. Chocolate fans might sprinkle ½ cup mini chocolate chips over the crust before adding the pineapple topping.
How To Keep Them Fresh
Keep these yummy bars at their best with the right storage. Leave them at room temp in an airtight container for up to 2 days, with parchment between layers so they don't stick together. For longer freshness, stick them in the fridge for up to 5 days, but let them come to room temp before eating for the best taste and texture. These freeze really well—wrap single pieces in plastic wrap, then foil, and freeze for up to 3 months. Thaw in the fridge overnight then let sit out for about an hour, or warm them slightly in a 300°F oven for 5-10 minutes to taste fresh-baked again.
These pineapple treats have become my go-to contribution for summer parties, but their bright island flavor makes them welcome any time of year. What I really love about this recipe is how something so simple can instantly lift your mood. The mix of buttery shortbread with sweet-tangy pineapple creates something that's way more special than you'd expect from such basic ingredients.

Recipe FAQs
- → Can I swap canned pineapple with fresh?
- Definitely! Just finely chop fresh pineapple and wring out the juice well, as too much liquid can make the bars soggy. For closest results, give it a quick pulse in a food processor.
- → How can I tell if the bars are done?
- Check for edges that are firm and lightly tinted golden while the middle might have a small jiggle – similar to lemon bars. They'll finish setting while cooling. Shield the edges with foil if they brown too fast.
- → Can I store these bars in the freezer?
- Of course! Slice them, place parchment between layers in an airtight container, and freeze for three months. Let them thaw overnight in the fridge and add fresh powdered sugar before serving.
- → Why’s my pineapple layer too watery?
- You probably didn’t drain the pineapple thoroughly enough. Make sure to press out every bit of liquid and pat it dry with a paper towel for best results.
- → Can I add other fruits to these?
- Yes! Toss in well-drained mango or papaya for extra tropical flavor. Just keep the total fruit to around 1 cup to avoid texture issues.
- → What’s the trick to cutting neat squares?
- Once the bars cool, chill them in the fridge for an hour. Use a sharp knife that’s warmed with hot water, and wipe it clean between slices. Save the powdered sugar dusting for after cutting.
