What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the star here is, of course, fresh strawberries—though frozen works in a pinch.

• For the Crust and Crumble:
  • All-purpose flour – 2 ½ cups (312g), for that perfect tender base and crunchy topping
  • Granulated sugar – ¾ cup (150g), adds sweetness and helps with crispness
  • Brown sugar – ½ cup (100g), for a subtle molasses flavor in the crumble
  • Unsalted butter – 1 cup (227g), cold and cubed (I recommend Kerrygold for rich flavor)
  • Baking powder – 1 teaspoon, to give the crust a slight lift
  • Salt – ½ teaspoon, to balance sweetness
• For the Strawberry Filling:
  • Fresh strawberries – 4 cups (about 600g), hulled and sliced (in summer, swap in fresh berries for best flavor)
  • Granulated sugar – ⅓ cup (67g), to sweeten the fruit
  • Cornstarch – 2 tablespoons, to thicken the juicy filling
  • Lemon juice – 1 tablespoon, brightens up the strawberries
  • Vanilla extract – 1 teaspoon, adds warmth and depth

If you want gluten-free bars, swap the all-purpose flour for almond flour or a gluten-free flour blend. For dairy-free options, use coconut oil or vegan butter instead of unsalted butter. Frozen strawberries can be used if fresh aren’t in season, though the texture will be slightly softer.

Equipment Needed

• 9×13 inch (23×33 cm) baking pan – essential for the right thickness of bars; a glass or metal pan works fine
• Mixing bowls – at least two, one for the crumble and one for the filling
• Pastry cutter or fork – handy for cutting cold butter into flour (a food processor speeds this up, but isn’t necessary)
• Measuring cups and spoons – for accurate ingredient amounts
• Spatula or wooden spoon – to mix the strawberry filling gently
• Cooling rack – lets the bars cool evenly without sogginess

Personally, I’ve used both a pastry cutter and my hands to mix the crumble; hands are messier but you get a better feel for the texture. A food processor can make the crumble topping super quick but be careful not to over-process or you’ll lose that crumbly texture.

Preparation Method

1. Preheat the oven to 350°F (175°C). Line your 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal later. This step prevents sticking and makes clean-up a breeze. (5 minutes)
2. Make the crumble base: In a large bowl, whisk together 2 ½ cups (312g) all-purpose flour, ¾ cup (150g) granulated sugar, ½ cup (100g) brown sugar, 1 teaspoon baking powder, and ½ teaspoon salt. Add 1 cup (227g) cold, cubed unsalted butter.
3. Cut the butter into the dry ingredients using a pastry cutter or your fingertips until the mixture resembles coarse crumbs with some pea-sized bits. The texture is key here—too fine and the bars get dense; too chunky and they won’t hold together well. (7-10 minutes)
4. Press about two-thirds of the crumble mixture firmly into the prepared pan to form the crust. Use the bottom of a glass or your fingers to get an even layer. Bake for 15 minutes or until lightly golden. This pre-baking helps the crust set so it won’t get soggy later. (15 minutes)
5. Prepare the strawberry filling: While the crust bakes, combine 4 cups (600g) sliced fresh strawberries, ⅓ cup (67g) granulated sugar, 2 tablespoons cornstarch, 1 tablespoon lemon juice, and 1 teaspoon vanilla extract in a bowl. Mix gently to coat all the fruit evenly. The cornstarch thicken the juices as it bakes, so don’t skip this step.
6. Remove the crust from the oven and evenly spread the strawberry filling over it. Don’t worry if it looks juicy—that’s a good thing! Now crumble the remaining third of the crumble mixture over the top, covering the filling. (5 minutes)
7. Bake again for 35-40 minutes, or until the topping is golden brown and the strawberry filling is bubbling around the edges. (35-40 minutes)
8. Cool completely in the pan on a wire rack. This step is crucial—cutting too soon will cause the filling to spill out. Once cooled, use the parchment overhang to lift the bars out and cut into squares. (1-2 hours)

Pro tip: If your crumble topping browns too fast, loosely tent the pan with foil halfway through baking. Also, let the bars sit overnight for even better flavor melding (if you can wait that long!).

Cooking Tips & Techniques

• Keep butter cold: Cold butter is the secret to flaky, crumbly texture. If it melts too soon, your topping turns greasy instead of crisp.
• Don’t overmix the crumble: Mix just until you see pea-sized bits. Overworking develops gluten and toughens the crust.
• Use fresh, ripe strawberries: They provide the best natural sweetness and texture. If berries are too tart, add a bit more sugar but be cautious.
• Thicken that filling: Cornstarch is your friend here. Without it, the strawberry juice can run and make cutting messy.
• Watch your oven temperature: Every oven is different, so keep an eye on the bars in the last 10 minutes to avoid burning the topping.
• Multitask smartly: While the crust bakes, prep your filling to save time. Efficiency is key when you’re hungry for a sweet snack!

I once forgot to pre-bake the crust and ended up with soggy bars—lesson learned the hard way! Also, letting the bars cool fully has saved me many crumbly messes when slicing. Trust the process; it’s worth the wait.

Variations & Adaptations

• Berry Mix-Up: Swap half the strawberries for blueberries or raspberries for a mixed berry crumble bar.
• Gluten-Free Version: Use almond flour or a store-bought gluten-free blend instead of all-purpose flour. The texture will be a bit different but still delicious.
• Vegan Adaptation: Replace butter with coconut oil or vegan butter sticks. Use maple syrup in place of sugar for a natural sweetener twist.
• Spiced Twist: Add ½ teaspoon cinnamon or a pinch of nutmeg to the crumble for a warm, cozy flavor.
• Nutty Crunch: Stir in ½ cup chopped walnuts or pecans into the crumble topping for extra texture and flavor.

Personally, I tried making these with a gluten-free almond flour crust once, and while the texture was a touch more crumbly, the flavor was just as irresistible. It’s a great way to enjoy the bars if you’re avoiding gluten. For a less sweet version, reduce the sugar in the filling by a tablespoon or two.

Serving & Storage Suggestions

These strawberry crumble bars are best served at room temperature or slightly chilled, letting the flavors shine through without being too mushy or cold. They pair beautifully with a scoop of vanilla ice cream or a dollop of whipped cream on the side for an extra-special treat.

For storage, keep bars in an airtight container in the refrigerator for up to 4 days. They also freeze wonderfully—wrap bars individually in plastic wrap, then place in a freezer-safe container for up to 3 months. To enjoy, thaw overnight in the fridge and warm briefly in the oven or microwave.

Interestingly, the flavors deepen after a day or two as the filling settles and the crumble softens just enough to be perfectly tender. So, if you can wait, these bars get even better with time.
