I’ve got these strawberries and cream oat bars for you, and they’re just what you want when you’re craving something sweet this summer. They have a lovely jammy strawberry centre and a buttery oat crumble. It’s a really comforting treat, perfect for a little snack or with your afternoon tea.
One thing that makes these homemade strawberry crumble bars really work is paying attention to the fruit. You drain the chopped strawberries before baking so the filling stays nice and jammy, not watery. And pressing the oat base firmly helps everything hold together properly.
I made a batch of these for a potluck last weekend, and they were gone so fast. They’re pretty versatile too, you can replace the strawberry with any berry you’d like! (I may have eaten four.)
Why you’ll love this recipe
Jammy strawberry filling: The centre of these bars is bursting with sweet strawberries, cooked down just enough to be soft and flavourful.
Buttery oat crumble: The base and topping are made from the same oat mixture, giving you a satisfying chew and a lovely texture contrast.
Subtle white chocolate: A delicate drizzle of white chocolate adds a touch of creamy sweetness without overpowering the fruit.

Tips for making strawberries and cream oat bars
- Drain strawberries well: After mixing your fresh chopped strawberries with sugar and cornstarch, let them sit for a minute or two and then drain any liquid. This step is key for a perfectly set, jammy filling in your strawberry oatmeal bars and stops the bottom from getting soggy.
- Press the base firmly: When you’re putting the bottom layer of oat mixture into the pan, really press it down with the back of a measuring cup or your hands. A compact base helps these homemade strawberry crumble bars hold their shape beautifully when you slice them.
- Melt white chocolate gently: Use a double boiler to melt the white chocolate chips for the drizzle. White chocolate can seize up and get clumpy easily if it gets too hot, so a gentle, indirect heat helps it melt smooth and glossy for your simple strawberry streusel bars.
- Cool completely: It’s so tempting to cut into these right away, but letting your make-ahead strawberry dessert bars cool fully in the pan is super important. They need time to set up properly, especially the strawberry filling, so they don’t fall apart.
Frequently asked questions
Can I use frozen strawberries? You can, but make sure they are fully thawed and then drained really well before mixing them with the sugar and cornstarch. Frozen berries release a lot more liquid than fresh ones.
How do I store these oat bars? Keep them in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. If it’s warm where you are, the fridge is probably better to keep the white chocolate from getting too soft.
Can I make these bars gluten-free? You could try using a 1:1 gluten-free all-purpose flour blend and certified gluten-free rolled oats. I haven’t tested it myself, but it should work fine.
What if I don’t have an 8×8 inch pan? A 9×9 inch pan would work too, but your bars will be a little thinner and might bake a few minutes faster. Keep an eye on them!

Strawberries and Cream Oat Bars
- Total Time: 50 minutes
- Yield: 16 bars 1x
Description
Ingredients
OATMEAL BASE AND CRUMBLE
- 1 1/2 cups (135 grams) rolled oats
- 1 1/2 cups (180 grams) all-purpose flour
- 1/3 cup (75 grams) light brown sugar, packed
- 1/2 teaspoon (2 grams) baking powder
- 1/2 teaspoon (3 grams) salt
- 3/4 cup (170 grams) unsalted butter, melted
- 1 teaspoon (5 ml) vanilla extract
STRAWBERRY FILLING
- 2 cups (300 grams) fresh strawberries, hulled and chopped
- 1/4 cup (50 grams) granulated white sugar
- 2 tablespoons (16 grams) cornstarch
- 1 tablespoon (15 ml) lemon juice
WHITE CHOCOLATE TOPPING
- 1/4 cup (45 grams) white chocolate chips
Instructions
- Prep the oven and pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch (20×20 cm) baking pan with parchment paper, leaving an overhang on all sides to easily lift the bars later.
- Mix the crumble base: In a large mixing bowl, combine the rolled oats, all-purpose flour, light brown sugar, baking powder, and salt. Whisk them together until well combined.
- Add wet ingredients: Pour the melted butter and vanilla extract into the oat mixture. Stir with a spatula or wooden spoon until the mixture resembles coarse crumbs.
- Form the base layer: Press about two-thirds of the oat mixture firmly and evenly into the bottom of the prepared baking pan. Use the back of a measuring cup or your hands to ensure it’s a compact layer.
- Prepare the strawberry filling: In a separate medium bowl, combine the chopped strawberries, granulated sugar, cornstarch, and lemon juice. Stir everything together until the strawberries are well coated.
- Drain the strawberries: Let the strawberry mixture sit for a minute or two, then carefully drain any excess liquid that has accumulated. This helps prevent a soggy bottom!
- Assemble the layers: Pour the strawberry filling evenly over the pressed oat base in the baking pan.
- Add the crumble topping: Sprinkle the remaining one-third of the oat mixture over the strawberry filling to create the crumble topping. Gently press the oats into the strawberry layer.
- Bake the bars: Bake for 30-35 minutes, or until the topping is golden brown and the strawberry filling is bubbly.
- Cool completely: Let the bars cool completely in the pan on a wire rack. This is crucial for them to set properly. Once cool, use the parchment paper overhang to lift them out of the pan.
- Melt the white chocolate: Set up a double boiler: fill a small saucepan with an inch or two of water and bring it to a simmer. Place a heatproof bowl on top of the saucepan (make sure the bottom of the bowl doesn’t touch the water). Add the white chocolate chips to the bowl and stir occasionally until fully melted and smooth.
- Drizzle and cut: Pour the melted white chocolate into a small Ziploc bag and snip a tiny corner off. Drizzle the white chocolate decoratively over the cooled oat bars. Let the chocolate set for a few minutes, then cut the bars into 16 squares or rectangles using a sharp knife.
Notes
- Don’t skip the strawberry drain! That little bit of excess liquid can make your bars a bit too wet. Draining it ensures a perfectly jammy, not watery, filling.
- Press that base layer firmly. Seriously, put some elbow grease into it! A well-compacted base is key for bars that hold together beautifully when you slice them.
- White chocolate can be finicky. The recipe specifies a double boiler for melting white chocolate for a reason. It’s much gentler than a microwave, which can easily overheat and seize the chocolate, turning it into a clumpy mess. Slow and steady wins the race here!
