Instructions
How to make Gluten Free Shortbread
Place a sheet of parchment paper at the bottom and along the sides to line the baking pan.I recommend leaving some excess paper over the edges of the pan to make it easier when removing the shortbread.
In a bowl, beat together butter and sugar until fully combined but not creamed as we don't want to add any air into the shortbread dough.
In a large bowl mix together the flour, cornstarch, xanthan gum, and salt.
Combine the flour mix with the butter and sugar mixture and knead together until it forms a dough.
Place the dough into the lined baking pan and spread out evenly. I like to use my hands to spread it in the pan and then use a small offset spatula to smooth out the surface. If preferred you can roll the dough on a piece of parchment paper to the size of the pan then lift it into the pan.
Using a knife cut into the dough about ¾ deep to score in the shape of the shortbread fingers and then pierce each shortbread finger with a fork a few times (See image 5 in the post above).
Place the Shortbread dough in the fridge for 15 minutes and Preheat the oven to 180°C/350°F/Gas mark 4.
Place in the oven for 50-60 minutes (Mine took 55 minutes) until slightly golden around the edges. Remove from the oven and place the baking pan on a cooling rack.
With a knife carefully go over the lines previously made while the shortbread is still soft. Sprinkle the top with the optional sugar if desired.
It is important to leave the gluten free shortbread in the baking pan on the cooling rack to fully cool before removing it from the pan as it will firm up nicely once fully cooled.
Notes
Tip #1:Quality ingredients - Using high-quality ingredients such as European butter that has a lower water content is essential as there are very few ingredients needed to make the gluten free shortbread so it really matters when it comes to achieving the best texture and flavor.
Tip #2: Don't overbeat - Stop beating once the butter and sugar are fully incorporated as too much air through over-beating will cause the top of the shortbread to puff up when baking and we don't want that.
Tip #3: Pricking the top - By scoring the lines of the shortbread cookies finger will make it easier for clean cuts after they have cooled. Pricking the tops of the cookies before baking will allow air to escape and help prevent the shortbread from puffing up during the baking process.
Tip #4:Chilling the dough - Chilling shortbread dough before baking helps solidify the butter, reduce cookie spread, enhance flavor, and make the dough easier to handle for a tender, crumbly texture and well-defined shape.
Tip #5:Let it fully cool - It is important to leave the gluten free shortbread in the baking pan on the cooling rack to fully cool after baking before removing it from the pan as it will firm up nicely once fully cooled.
