Rich and buttery, this vegan brown butter shortbread is sublime topped with lemon-infused icing sugar. While this may sound fancy, rest assured, the recipe is kid simple: 1 bowl, 1 minute of mixing, then straight into a cake pan and into the oven.
Having said that, you do need to make the vegan brown butter ahead of time, as it needs to be chilled a few hours before using.

Ingredients
There are just 4 ingredients in this recipe: vegan brown butter, rice flour, icing sugar, and cake and pastry flour. Make the vegan brown butter earlier in the day or the night before and chill it. It won’t harden when chilled, but it will be a thick, pourable consistency.

The rice flour helps make the shortbread tender. I originally used the cake and pastry flour as it was all I had on hand, but I liked the end result, so kept with it. Rice flour and cake and pastry flour both have a lower protein content than regular flour, resulting in more tender baked goods.

The Process
There’s a visual of the process below. It’s very straightforward: Once you have the chilled vegan brown butter, it’s just a matter of putting all the ingredients in a bowl and mixing until well-combined, about 1 minute or so. Butter the sides and bottom of a cake pan with some vegan brown butter. Spoon the cookie dough into the pan, levelling it out. It doesn’t have to be perfectly flat as it will rise in the oven and even out somewhat.
Bake at 300F for about 20 minutes and then remove and let cool. The cookie dough will have risen but it will fall a bit in the pan while cooling.
Once cooled, run a knife around the edge of the cookie and then cut it into triangles. We made 16 cookies as they are quite rich.
If you want to garnish the cookies with the lemon-infused sugar like we did, remove the cookies from the cake pan and line them up to form a circle in the same way they came out of the pan. Put something lacy on top — like a doily. I used a placement from CB2 that looks a bit like a doily and it did the trick. You could even make a paper snowflake and use that.

Carefully remove the doily and your cookies are dusted with lemony-sugar and ready to impress.

Before you make this shortbread check out the Dark Chocolate Bark Recipe and also Vegan Brown Butter Chocolate Chip Cookies. Making all 3 of the recipes on the same day would be a great idea. Make enough vegan brown butter for both kinds of cookies and then use the buttery pecans that result from the vegan brown butter-making process in the Dark Chocolate Bark. You will not regret this!
