Every ingredient in this Strawberry Crumble Bars Recipe is simple yet essential, carefully chosen to create a perfect harmony of texture, flavor, and color. From the wholesome flours that build the sturdy yet tender crust to the juicy strawberries that make the filling sing, each element plays a crucial role in delivering a beautiful balance of tastes and textures.

Almond flour (1 ½ cups, packed, 168g): Provides a nutty flavor and tender crumb that makes the crust remarkably moist without being dense.
Oat flour (1 ½ cups, 138g): Adds heartiness along with a slightly chewy texture that complements the crumble topping beautifully.
Oats (¾ cup, 71g): Brings a rustic chewiness and enhances the crumble’s golden crunch when baked.
Salt (½ teaspoon): Elevates the sweetness of the strawberries while balancing the richness of the crust.
Salted butter (½ cup, melted and cooled, 113g): Infuses a luscious buttery flavor and helps create that irresistible crumbly texture. Substitute vegan butter or melted coconut oil for a dairy-free option.
Pure maple syrup (⅓ cup, 104g): A lovely, natural sweetener that also gives a subtle, sophisticated depth of flavor to the crust and filling.
Vanilla extract (½ teaspoon): Adds a warm, aromatic touch that ties all the flavors together.
Fresh strawberries (1 pound, diced, 454g): The star of the show – juicy, sweet, and tart berries bursting with fresh flavor for the filling.
Cornstarch or arrowroot starch (1 tablespoon): Acts as a thickener to give the filling the perfect luscious consistency without being runny.
Lemon juice (1 teaspoon): Adds brightness and enhances the natural strawberry flavor.
Almond extract (¼ teaspoon): Provides a delicate nutty aroma that complements the berries beautifully; vanilla extract works well as a substitute.

How to Make Strawberry Crumble Bars Recipe

Step 1: Prepare the Oven and Pan

Start by preheating your oven to 350 degrees Fahrenheit. Line a 9×9 inch baking pan with parchment paper and give it a quick spray with nonstick cooking spray—this small step ensures your bars come out perfectly without sticking, making cleanup such a breeze.

Step 2: Make the Crust and Topping

In a large bowl, whisk together almond flour, oat flour, oats, and salt with a fork until combined. Then, stir in the melted, cooled butter, pure maple syrup, and vanilla extract until you have a crumble that starts to clump together. Set aside one cup of this dough for the topping – trust me, that topping is going to add such a satisfying crunch! Press the remaining dough firmly and evenly into the bottom of your pan as the base crust.

Step 3: Bake the Crust

Bake your crust for about 10 minutes until it’s just beginning to firm up and lightly golden. This gives you a sturdy base that won’t get soggy under the juicy strawberry filling.

Step 4: Make the Strawberry Filling

While the crust bakes, combine diced strawberries, maple syrup, cornstarch (or arrowroot starch), lemon juice, and almond extract in a medium pot over medium heat. Bring it to a gentle simmer, then lower the heat and cook for 3 to 5 minutes, stirring often until the mixture thickens slightly and strawberries have released their mouthwatering juices. The filling should be thick but still juicy, perfect for spooning onto your crust.

Step 5: Assemble and Bake

Pour the luscious strawberry filling over your pre-baked crust, using a spoon to spread it evenly. Sprinkle the reserved crumble topping over the filling. Pop the pan back into the oven and bake for 35 to 45 minutes. You’ll know it’s done when you see the filling bubbling at the edges and the topping turns a gorgeous golden brown. Then the toughest part: letting the bars cool completely to firm up before slicing. I like to chill mine in the fridge to speed this up.

How to Serve Strawberry Crumble Bars Recipe

A square piece of dessert sits on a white plate with a scalloped edge on a white marbled surface. The dessert has three layers: the bottom layer is a thick, golden-brown base, the middle layer is a bright red strawberry filling, and the top layer is a crumbly, light brown streusel topping scattered unevenly. A half strawberry with its green stem lies next to the dessert on the plate, while some small oatmeal crumbs are scattered around. The background is bright and clean, with more pieces of the same dessert blurred in the distance. photo taken with an iphone --ar 4:5 --v 7

Garnishes

For a special touch, garnish your strawberry crumble bars with a light dusting of powdered sugar or a few fresh strawberry slices. A small drizzle of melted dark chocolate or a sprinkle of finely chopped toasted almonds also adds an extra layer of flavor and texture that takes these bars to the next level.

Side Dishes

These bars go fabulously with classic sides like a scoop of rich vanilla ice cream or a dollop of freshly whipped cream. For a healthier option, a spoonful of Greek yogurt with a drizzle of honey complements the tartness of the strawberries beautifully.

Creative Ways to Present

Cut your bars into bite-sized squares and serve them on a pretty platter with edible flowers for a charming, elegant touch. Or, layer crumbled strawberry crumble bars over vanilla pudding or custard for a fun parfait-style dessert. Don’t be afraid to get creative—these bars are versatile and shine in any form!

Make Ahead and Storage

Storing Leftovers

Your strawberry crumble bars keep wonderfully in an airtight container at room temperature for up to two days, or refrigerated for up to a week. The cooler temp helps maintain that perfect balance between juicy filling and crumbly topping.

Freezing

If you want to enjoy these bars later, wrap them well in plastic wrap and aluminum foil, then freeze for up to three months. Thaw overnight in the fridge and you’re good to go—almost like freshly baked!

Reheating

Reheat individual bars gently in the microwave for 15 to 30 seconds to warm through without drying out. For a crispier texture, a quick 5-minute bake in a 325-degree oven brings back that crunchy topping magic.

FAQs
