I made another batch of Gluten Free Peanut Butter Cup cookies. These cookies are courtesy of the recipe from The Baking Beauties. But I didn't have any tapioca starch in the pantry. Feeling daring, I added more potato starch to fill the void. And it worked! And that is when the happy dance in the kitchen commenced in the kitchen.
Tapioca starch is used to help inflate, lighten and brown your baking. I found that these cookies inflated nicely when they were in the oven and I think they have a nice colour to them. I did bake them in the oven with the rack at the mid-range. So thrilled they turned out.
