In a bowl, sift together 2¾ cup all purpose einkorn flour, ½ tsp baking powder, ½ tsp baking soda, 2 ½ tsp arrow root and ½ tsp salt. Sift 3 times and set aside.
In a large bowl whish together1 egg plus 1 egg white, 1 cup organic sugar and ¼ tsp cream of tartar. Whip about 90 seconds until bubbly and fluffy.
With a spatula, fold in ¼ cup organic sour cream, 1½ tsp organic vanilla extract and ¼ tsp organic almond extract. Use a spatula and mix well, but don't over mix.
Add in 1/3 at a time the flour mixture. Again, use a spatula and combine completely.
Cover with a tea towel or plastic wrap and place in the refrigerator for 1 ½ to 2 hours.
Preheat the oven to 375℉.
Line a baking sheet with parchment paper.
Using a medium cookie scoop, scoop out and place 12 scoops spaced about 2 inches apart onto the parchment lined baking sheet.
Rip a small piece or parchment paper from the roll. Use the bottom on a glass. One at a time place the parchment paper on top of the ball of cookie dough and then place the glass on top and press to ¼ to ½ inch thick.
Bake for 7- 8 minutes. Watch closely... you don't want to overcook. Remove from the oven and let cool.
Frost with the buttercream frosting once cooled.
