FAQs

Can I use fresh raspberries instead of preserves?
Yes, you can use fresh raspberries, but they may not create the same swirl effect. You can mash them slightly and mix them into the batter or just use them on top.

What if I don’t have lemon juice?
If you don’t have lemon juice, you can substitute it with an equal amount of lime juice. The flavor will be different but still tasty!

Can I make these bars gluten-free?
Yes, you can use a gluten-free all-purpose flour blend in place of regular flour to make these bars gluten-free. Just make sure that the blend contains xanthan gum for the best texture.
