Recipe Developer Tips

  • Reach for ripe raspberries. If don’t have ripe berries it will create a sour flavor. Ripe berries will enhance the sweetness.
  • The cornstarch is going to help the raspberry mixture to thicken up. You could also use tapioca starch if you would prefer.
  • When you put the first shortbread layer make sure to create an even layer. I used my fingers to press it into the pan. You could also use the back of a measuring cup for pressing.
  • Don’t overbake the bars or it will dry out the shortbread quickly.
  • Allow the bars to cool completely before you drizzle on the white chocolate.

Refrigerate – Make sure you refrigerate any of the bars in the fridge. Place in a sealed container for 3-4 days. You will find the raspberry bars will dry out as they are in the fridge.

Freezer – Go right ahead and slice and freeze the bars in a sealed container or freezer bag. Freeze for 2-3 months. Then thaw in the fridge overnight.


Can I make raspberry bars ahead of time?

You can make these raspberry bars ahead of time, and just store them in the fridge in a sealed container. You can enjoy these crumble bars straight from the fridge.

How can I make the bars gluten-free?

Yes, reach for a gluten-free flour blend in replace of the all-purpose flour. It will alter the texture of the bars a bit but will still be tasty.

Can I use other fruits instead of raspberries?

Go right ahead and add different fruit if you want, or pair it with another fruit of your choice. Peaches, strawberries, and blueberries, all would be great planning.

Can I use frozen raspberries instead of fresh ones?

Absolutely. Just make sure to thaw the raspberries first, and then mash and mix in the ingredients.
