Guava Coconut Crumble is an easy pan dessert with a thick guava layer under a buttery coconut crumble. It’s sweet in that classic guava-paste way, with a little tang, and I like how it slices into neat little squares for sharing.

The flavor here is very Caribbean Latin to me: bright guava, a hint of lime, and that toasty coconut on top. I also love that the crust and crumble are the same mixture, so you’re not juggling extra bowls or steps.

I make these when I want something that looks “baked” and a little special, but still feels low effort and reliable. They’re especially good with coffee or a simple after-dinner tea.

Why You’ll Love This Recipe

One-bowl crumble: The crust and topping are the same mixture, which keeps the whole thing straightforward.

Big guava flavor: Guava paste bakes up into a thick, jammy filling that tastes like guava candy in the best way.

Great texture: You get a sturdy base, a soft fruit layer, and a golden, sandy crumble on top.

Easy to slice and share: Once it’s cooled, it cuts cleanly into squares that travel well for potlucks and dessert tables.

Flexible sweetness: You can tweak the coconut and sugar a bit if you like your bars less sweet.

Guava paste can look a little intimidating if you haven’t used it before, but it’s just a firm fruit paste (usually sold in a box) that melts down quickly with a splash of water. I keep this baked in an 8-inch square pan so the filling stays thick and the bars don’t feel skimpy.

One small note: these really do slice better once they’re fully cool. If you’re the type who likes sharp edges, a short chill in the fridge helps a lot.

Key Ingredients

Guava Filling

Guava paste: I like paste here because it bakes into a thick, smooth layer that holds its shape. If you only have guava jam, that works too, but it may spread a little thinner.
Water: This is just to help the guava paste melt into something you can spread. If your paste softens quickly, you may not need quite as much.
Lime juice: Don’t skip it. The little bit of tang keeps the guava from tasting flat.
Vanilla extract: It rounds out the fruit flavor and makes the filling taste more dessert-like.
Salt: A small pinch makes the guava taste brighter and keeps the filling from being one-note.

Coconut Crust and Crumble

All-purpose flour: I use regular flour here and keep it simple. It gives the bars structure so they slice cleanly.
Sweetened shredded coconut: This adds sweetness and that chewy-toasty coconut bite. Unsweetened coconut is fine if you want to dial the sweetness back.
Light brown sugar: Brown sugar works especially well with guava and coconut. Dark brown sugar is fine too if that’s what you have.
Baking powder: Just a little helps the crumble bake up a touch lighter instead of dense.
Kosher salt: This keeps the crust and topping from tasting overly sweet. If you use fine salt, use a little less.
Unsalted butter: Melted butter makes this quick, and it gives you that classic buttery crumble flavor.
Egg: The egg helps the crumbs hold together so you can press in a firm crust.
Vanilla extract: I like vanilla in the crust too because it ties in with the guava filling.

Optional

Ground cinnamon: A small pinch is nice if you want a warmer, bakery-style spice note with the coconut.
Powdered sugar: I’ll dust a little over the top if I’m serving these on a platter. Totally optional.

Recipe Instructions

Preheat the oven: Heat the oven to 350°F. Line an 8-inch square pan with parchment paper and lightly grease it.
Warm the guava: Dice the guava paste so it melts faster. Add it to a small saucepan with the water and warm over low heat, stirring often, until smooth and spreadable.
Finish the filling: Stir the lime juice, vanilla, and a pinch of salt into the warm guava mixture. Set it aside to cool slightly while you make the crumble.
Mix the dry ingredients: In a medium bowl, whisk the flour, shredded coconut, brown sugar, baking powder, and kosher salt.
Add the wet ingredients: Stir in the melted butter, egg, and vanilla until you have large, moist crumbs and the mixture holds together when pressed.
Press in the crust: Add about two thirds of the crumb mixture to the prepared pan and press it in firmly into an even layer.
Spread the filling: Spread the guava filling evenly over the crust, all the way to the edges.
Top with crumbs: Sprinkle the remaining crumb mixture over the guava layer, then gently press it down a little so it sticks.
Bake: Bake for about 35 minutes, until the top is golden and the filling is bubbling at the edges.
Cool: Cool completely in the pan before slicing. For extra clean squares, chill for about 30 minutes, then cut into 9 servings.

My Tips!

This is the section that separates “good” from “wow.” If you read only one part of this post, make it this one — it’s where I reveal my recipe trick.

Recipe Tips & Tricks

Cut the guava paste small. Big chunks take longer to melt and you’ll end up stirring forever. Smaller cubes soften quickly and turn smooth with less water.

Keep the heat low for the filling. Guava paste can scorch if you crank the burner. Low heat and steady stirring gives you a smooth, spreadable filling.

Press the bottom layer firmly. If the crust is loosely packed, it can crumble when you slice. I press it down well, especially around the edges and corners.

Watch the edges for doneness. I don’t rely only on color here—look for bubbling around the sides. That’s a good sign the guava layer is hot and set.

Chill before slicing if you want clean squares. Once fully cooled, a short chill tightens everything up and makes the cuts much neater.

Simple tweaks

Here’s where the fun begins — a few simple tweaks can turn this recipe from casual treats into the star of any party.

Serving Suggestions

Coffee or espresso: These bars are really good with coffee, especially if you like a slightly bitter drink next to a sweet dessert. I usually go for plain coffee or a café con leche.
Ice cream: Vanilla ice cream on the side is simple and works with the guava and coconut. If you have it, coconut ice cream is also great here.
Fresh fruit: A few slices of mango, pineapple, or strawberries make the plate feel a little lighter. I do this a lot when I’m serving these after dinner.
Powdered sugar: A light dusting on top makes them look finished, especially for a party tray. Do it right before serving so it doesn’t melt in.

Eat it later

This section explains how to store leftovers properly and how far in advance the recipe can be prepared.

Storage and Make Ahead

Store leftovers covered in the fridge for up to 4 days. I keep them right in the pan with foil over the top, or in a sealed container once they’re sliced.

These bars are nice cold, but you can also warm a square briefly in the microwave if you want the filling softer. The crumble won’t be as crisp, but it’s still very good.

You can make this recipe ahead for parties since it slices best after it’s cooled and rested a bit. I’ll often bake it the night before, then cut it the next day.

If you want them to last longer, freeze individual portions in a tight container. Thaw in the fridge overnight before serving.

Recipe FAQs

Can I use guava jam instead of guava paste?

Yes. Guava jam works, but it’s usually looser than paste, so use less water (or skip the water completely) and just warm it enough to spread easily.

Why do my bars crumble when I slice them?

The most common reason is slicing too warm. Let the pan cool completely, and if you want really clean squares, chill the bars for 30 minutes before cutting.

Can I use unsweetened coconut?

You can. The bars will be less sweet and a bit more coconut-forward, which I like. If you switch to unsweetened coconut, reducing the brown sugar a little usually makes sense too.

How do I know when it’s done baking?

Look for a golden top and bubbling around the edges of the guava layer. If the top is browning fast but you don’t see bubbling yet, loosely cover with foil and keep baking a few more minutes.
