FAQs

Can I use frozen blueberries instead of fresh?

Yes, but thaw and drain them first to prevent excess moisture.

Do I need to use salted butter?

You can use unsalted butter, but add a pinch of salt for balance.

Why is my filling too runny?

Ensure the bars chill for at least 2 hours before slicing. The filling will firm up as it cools.

Can I make these bars ahead of time?

Yes! Prepare them a day in advance and keep them refrigerated until serving.

How do I get clean slices?

Use a sharp knife, wiping it clean between cuts for neat squares.

Can I make this in a larger pan?

Yes, but double the ingredients for a 9×13-inch pan and adjust the baking time.

Is sweetened condensed milk necessary?

Yes, it thickens the filling and provides sweetness. There’s no direct substitute.

Can I add a meringue topping?

Yes! Pipe meringue on top after baking and broil for a golden finish.

What pairs well with these bars?

Enjoy them with whipped cream, vanilla ice cream, or a hot cup of tea.

Can I use Meyer lemons?

Absolutely! Meyer lemons add a slightly sweeter, floral citrus flavor.
