Can I use frozen mulberries for Mulberry Crumble Bars?

Yes, frozen mulberries work very well in Mulberry Crumble Bars. There is no need to thaw them completely before baking. However, because frozen berries release extra moisture, you may want to add a little more cornstarch to keep the filling thick and prevent soggy bars.

How do I store Mulberry Crumble Bars?

Store Mulberry Crumble Bars in an airtight container at room temperature for up to two days. For longer freshness, refrigerate them for up to one week. The bars can also be frozen individually for convenient make-ahead desserts.

Why are my berry crumble bars falling apart?

Berry crumble bars usually fall apart if they are sliced before cooling completely. Allow the bars to cool fully so the filling can set properly. Chilling them briefly in the refrigerator also helps create cleaner slices.

Can I make Mulberry Crumble Bars gluten-free?

Absolutely. To make gluten-free Mulberry Crumble Bars, substitute the all-purpose flour with a high-quality gluten-free flour blend and ensure the oats are certified gluten-free. The texture remains deliciously crumbly and satisfying.

Instructions

Preheat the oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper.
In a medium bowl, combine the fresh mulberries, granulated sugar, 2 tablespoons flour, cornstarch, and lemon juice. Stir gently until evenly coated and set aside.
In a large mixing bowl, combine 3 cups flour, rolled oats, brown sugar, baking powder, and salt.
Pour the melted butter into the dry mixture and stir until a crumbly texture forms.
Press two-thirds of the crumble mixture firmly into the bottom of the prepared baking pan to create the crust.
Spread the mulberry filling evenly over the crust, including any accumulated juices.
Sprinkle the remaining crumble mixture evenly over the top of the berries.
Bake for 40 minutes or until the topping is golden brown and the filling is bubbling around the edges.
Allow the Mulberry Crumble Bars to cool completely before slicing into squares and serving.

Notes

Store the bars in an airtight container at room temperature for up to 2 days or refrigerate for up to 1 week.
Frozen mulberries may be used, but add extra cornstarch if the filling seems too watery.
For cleaner slices, chill the bars in the refrigerator before cutting.
Mulberries can be substituted with raspberries, blackberries, or mixed berries.
Serve warm with vanilla ice cream for an extra comforting dessert.
