Ingredients You’ll Need

Here’s what makes these crumble bars shine:

• All-purpose flour: Forms the sturdy base and crumbly topping.
• Brown sugar: Adds a rich caramel-like sweetness and moisture.
• Butter: Provides that golden, buttery crumble and delicious depth of flavor. Cold butter is key!
• Rolled oats: Brings texture to the crumble topping and a bit of rustic charm.
• Salt: Balances the sweetness and enhances the other flavors.
• Fresh or frozen blueberries: These give the bars their juicy, tangy core. No need to thaw frozen ones—just toss them in.
• Cornstarch: Helps thicken the berry layer as it bakes, so the bars don’t get soggy.
• White chocolate chips: Sweet, creamy, and a perfect match for the blueberries.
• Vanilla extract: Adds warmth and rounds out the flavors.

Variations

• Berry Swap: Try raspberries, blackberries, or a mix for a new twist.
• Dark Chocolate Love: Substitute dark or milk chocolate chips for a richer contrast.
• Nutty Crunch: Add chopped pecans, walnuts, or sliced almonds to the crumble for extra texture.
• Citrus Pop: Stir in a little lemon or orange zest to the berry mixture for a bright, zesty kick.

How to Make White Chocolate Blueberry Crumble Bars

Step 1: Make the Crumble Dough

In a large bowl, mix flour, brown sugar, oats, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture is crumbly. Set aside 1 cup of the crumble for the topping.

Step 2: Press the Base

Press the remaining crumble mixture firmly into a greased or parchment-lined baking dish to create an even crust. This will form the base of your bars.

Step 3: Add the Blueberry Filling

In a separate bowl, toss the blueberries with cornstarch and a splash of vanilla extract. Spoon the mixture evenly over the crust.

Step 4: Sprinkle the Good Stuff

Sprinkle white chocolate chips over the blueberry layer, then top with the reserved crumble.

Step 5: Bake to Golden Perfection

Bake at 350°F (175°C) for 35–40 minutes, or until the top is lightly golden and the blueberry layer is bubbling around the edges.

Step 6: Cool and Slice

Let the bars cool completely in the pan before slicing. This helps them set up nicely and makes cutting them a breeze.

Pro Tips for Making the Recipe

• Use Cold Butter: This is crucial for that perfect crumbly texture. Soft or melted butter will make the dough too wet.
• Line the Pan: Use parchment paper for easy removal and less mess.
• Cool Completely: As tempting as it is to dig in right away, let the bars cool fully for the cleanest slices.
• Don’t Overbake: The bars will firm up as they cool, so take them out when the edges are golden and the center still has a little give.

How to Serve

These bars are delightful just as they are, but here are some serving ideas to take them up a notch:

Pair with a Beverage

A hot cup of coffee, a cold glass of milk, or even a chilled herbal tea pairs beautifully with the sweet, fruity richness of these bars.

Dessert Plate

Serve them warm with a scoop of vanilla ice cream or a dollop of whipped cream for an easy but elegant dessert.

Brunch Spread

They make a lovely addition to any brunch table—alongside fresh fruit, muffins, and yogurt parfaits.

Make Ahead and Storage

Storing Leftovers

Keep the bars in an airtight container at room temperature for up to 2 days, or refrigerate them for up to 5 days for extra freshness.

Freezing

Wrap individual bars tightly in plastic wrap and freeze in a zip-top bag. They’ll keep for up to 2 months. Thaw at room temp or reheat gently in the microwave.

Reheating

To warm them up, pop a bar in the microwave for 10–15 seconds. If you’re feeling fancy, serve warm with a drizzle of white chocolate sauce.

FAQs

Can I use frozen blueberries?
Absolutely. Just toss them in frozen—no need to thaw. You may need to add an extra teaspoon of cornstarch to absorb the additional moisture.

Can I make these bars gluten-free?
Yes! Use a good 1:1 gluten-free flour blend and certified gluten-free oats. The texture might be slightly different but still delicious.

What if I don’t have white chocolate chips?
You can chop up a white chocolate bar or use milk or dark chocolate chips instead. The flavor will change slightly, but it’ll still be a treat.

Can I double the recipe?
Definitely. Just bake it in a larger pan, like a 9×13-inch dish, and add a few extra minutes to the baking time. Keep an eye on the top for golden doneness.
