Substitutions for Blueberry Bars Recipe:
Salted Butter: Butter is essential to this recipe. We haven't tried it with dairy free butter but it might work!
White Sugar: We don't recommend substituting white sugar unless you have to, but White sugar can be used interchangeably with brown sugar.
You can add 1 teaspoon of molasses to white sugar to make brown sugar. Check out this post on Sugar Substitutes for Baking for other ideas.
All Purpose Flour: We don't recommend substituting the flour, but you can check out this article on Cake Flour vs. All-Purpose Flour or Substitutions for All-Purpose Flour
Vanilla Extract: Helps to add flavor, we don't recommend substituting.
Cornstarch: Cornstarch is essential in bringing the blueberry filling together, we don't recommend substituting this.
Ground Cinnamon & Ground Ginger: Helps to add flavor, we don't recommend substituting.
Salt: We don't recommend leaving out the salt. Salt is necessary for balancing sweetness and bringing out those flavors.
Fresh Blueberries: Fresh store-bought blueberries, fresh wild blueberries, and frozen blueberries will all work beautifully in this recipe. You could also try apples with our Easy Apple Pie Bars.

Ellen Brookhart
These bars are delicious!!! They were also so easy to make! We used frozen blueberries and cooked them straight from the bag frozen and it still turned out amazing. You will not regret making these!

Hi Ellen,
Thanks for mentioning frozen berries. Didn't know whether to use them or not.
Pat

Yes, you can use frozen berries - it says it in the post.
Kris
I made these. I thought they were delicious, but I had to make 2 adjustments. First- the crust would just not come together for me without adding liquid. In this case, I added about 3 tbsp milk. Second- I had to bake the crust longer as well as the bars longer. I added about 10 mins to the baking time for each. Maybe it was just me, but I thought I would pass along. Thanks!

Has anyone tried to make these delicious looking bars gluten-free? If so what changes did you make or what flour did you use?
Liz @ Tasty Treats & Eats
I haven't tried it but maybe Bob's Red Mill All Purpose GF flour would work?
