FAQs

Can I use frozen raspberries instead of fresh?
Yes, you can use frozen raspberries. Just thaw them and drain any excess moisture before adding them to your batter.

Can I make these bars gluten-free?
Absolutely! Substitute all-purpose flour with a gluten-free flour blend suitable for baking.

What can I do if I don’t have lemon juice?
If you don’t have lemon juice, you can use lime juice as an alternative. It will give a slightly different flavor but still works well with the raspberries.
