In a double broiler over medium to medium low heat combine the egg whites and sugar. Mix them together until the sugar dissolves. Do not let the mixture boil.
Add your egg mixture to a mixer with a whisk attachment and mix until stiff peaks form.
Sift the Think. Eat. Live. SunFlour and powdered sugar together into the egg whites.
Slowly fold the dry ingredients into the egg whites. If you are adding food coloring add a few drops in once the dry ingredients have just been combined. Continue to stir the mixture until it flows off the spoon without breaking.
Grab 2 baking sheets and either line them with an oven safe silicon mat or parchment paper. Add your mixture into a piping bag with a circle tip and pipe uniform circles 1/2 inch apart.
After the circles have been piped tap the sheet several times against the counter. Set the trays aside undisturbed for around 1 to 1.5 hours.
When a thin film has formed on the top of the cookies place one sheet at a time into an oven preheated to 325 degrees. Rotating the tray every 5 minutes bake the cookies for 15-20 minutes. Cookies are best enjoyed after a couple hours in the fridge and can even be stored in the freezer!
