Can I use frozen mulberries for Mulberry Crumble Bars?

Yes, frozen mulberries work perfectly for Mulberry Crumble Bars. There’s no need to thaw them beforehand, but you may want to add a bit more cornstarch to account for extra moisture. This helps keep the filling thick and prevents sogginess.

How do I store Mulberry Crumble Bars?

Mulberry Crumble Bars can be stored in an airtight container at room temperature for up to two days. For longer storage, keep them in the refrigerator for up to a week. You can also freeze them for up to three months and thaw before serving.

Why are my Mulberry Crumble Bars too soft?

If your Mulberry Crumble Bars turn out too soft, it could be due to excess moisture in the fruit or not enough thickener. Make sure to use the right amount of cornstarch and allow the bars to cool completely so the filling can set properly.

Preheat oven to 350°F (175°C) and line a baking pan with parchment paper.
In a large bowl, mix flour, oats, granulated sugar, brown sugar, and salt.
Add melted butter and vanilla extract, then stir until crumbly.
Reserve one-third of the mixture for topping and press the rest into the pan to form the crust.

Spread the mulberry mixture evenly over the crust.
