In a bowl, combine the butter, sugar and salt. Give it a nice mix.
Add the egg and continue to mix.
Mix until you get a smooth, uniform consistency.
Add the coconut flour and mix well to combine.
Spread this mixture in a thin layer on a parchment paper lined baking sheet.
Pop it in the oven preheated at 350 F for 7-10 minutes, or until it looks light golden brown.
Allow it to cool down completely and then scrape the baked mixture off the parchment paper, breaking it into small flakes.
Use immediately or store for later.
Notes
If you want to make colored flakes, add a drop of food coloring into the mixture.
You can also try using gluten-free flour or cake flour to make these Feuilletine flakes.
Fresh orange zest, a pinch of ground cinnamon or pumpkin pie spice or some spiced orange honey can be great additions to the Feuilletine mixture, for that extra depth of flavor.
Create a thin layer of the mixture on the parchment paper. A thick layer will not have that crispy texture and will take longer to brown.
Keep an eye on the tray at the 7-8 minute mark, and remove it from the oven once it starts to look golden brown.
