These strawberry crumb bars are soft, buttery, and layered with sweet jam and fresh strawberries. The same crumb mixture is used for both the base and topping, making them an easy summer dessert.
Â
Strawberries are always a favorite in summer, and these bars are a simple way to use them. Made with an easy crumb dough that doubles as both the base and topping, they bake up with a sweet jam and fresh berry center that’s soft and full of flavor.
If you’ve made my raspberry crumb bars, this version will feel very familiar, just with a slightly sweeter, softer berry flavor. Unlike a classic strawberry crumble, these are firm enough to slice into bars, and they tend to disappear fast, especially with a dusting of powdered sugar or a scoop of vanilla ice cream.
Ingredient Notes
- Flour: All-purpose flour gives the strawberry crumb bars structure while still keeping them tender.
- Rolled oats: Old-fashioned rolled oats work best here. They’re a bit larger and give the crumb a nice texture with just a hint of chew.
- Butter: Melted butter keeps the mixture easy to bring together and gives the bars their rich, buttery flavor.
- Granulated sugar: Adds sweetness and helps create that soft, tender base.
- Brown sugar: Brings a light molasses flavor and a little extra moisture to the crumb.
- Strawberries: Fresh strawberries work best, chopped so they soften and bake evenly into the center. If your berries aren’t very sweet, you can toss them with 1 to 2 teaspoons of sugar before adding.
- Strawberry jam: Creates that soft, flavorful layer in the middle and helps bind the fresh berries together. If you have a homemade strawberry jam, even better.
- Vanilla and salt: Simple additions that round out the flavor and balance the sweetness.

How to Make Strawberry Crumb Bars
Start by preheating your oven and lining the pan with parchment paper. It makes lifting the bars out so much easier later, especially since the centre stays soft.
In a large bowl, mix together the flour, oats, melted butter, vanilla, sugars, and salt. The mixture should look crumbly but hold together when pressed.

Press about half of the mixture firmly into the bottom of the pan. I like to use the back of a spoon or even my hands to really pack it down so it bakes into a solid base.

Spread the strawberry jam evenly over the base, then scatter the chopped strawberries on top. Don’t worry about making it perfect, it all settles as it bakes.

Sprinkle the remaining crumb mixture over the top. Keep it loose and crumbly rather than pressing down so you get a classic textured finish.

Bake until the top is lightly golden and the centre looks set. The strawberry crumb bars may still feel slightly soft in the middle, but they will firm up as they cool. Cool completely then chill before slicing for clean bars.Â

recipe tips
- Use a food processor if you like: You can pulse the crumb mixture in a food processor to bring it together quickly, just don’t over process. It should stay crumbly, not turn into a paste.
- Don’t worry if they look soft: The center will look quite jammy when the strawberry crumb bars come out of the oven. That’s exactly how it should be, they firm up as they cool and chill.
- Press the base firmly: Take a moment to really press the bottom layer into the pan so it holds together once sliced.
- Chill before slicing: It might be tempting to cut them warm, but a short chill makes a big difference for clean, neat bars.
- Garnish: Before serving dust with powdered sugar and then serve with a scoop of my no churn vanilla ice cream (or your favorite brand).

Variations to Try
- Use different berries: Blueberries, raspberries, or even chopped cherries all work well here. Just keep the same amount and adjust sweetness slightly if needed.
- Add lemon zest: A little lemon zest mixed in with the fresh strawberries really brightens the flavor and makes them pop.
- Make a shortbread-style base: For a more classic bar, you can skip the crumb topping and use a pressed shortbread-style crust and topping like in my coconut jam squares.
- Add a simple glaze: Instead of dusting with powdered sugar, drizzle the cooled bars with a quick glaze made from powdered sugar and a little milk or lemon juice.
Can I use frozen Strawberries?
For these strawberry crumb bars, I recommend using fresh strawberries for the best texture and flavor.
If you want to make them year-round, frozen strawberries can work with a few extra steps.
First, thaw the berries and drain them well. I like to pat them dry too. If they still seem watery, stir in a teaspoon of cornstarch to help thicken the filling as it bakes.

These Strawberry Crumb Bars are the perfect combination of buttery crumb topping and sweet juicy strawberries in every bite. Easy to make and perfect for dessert, snacking, or summer gatherings, they’re a simple treat everyone will love. Buon Appetito!
