Mix together the powdered Sugar mixture. Spray a 8 or 9 inch baking dish and generously dust some of the powdered sugar mixture. Set the rest of the mixture aside.
In a mixing bowl add 1/2 cup of cold water and the 2 gelatin packets to let bloom.
In a saucepan, add the remaining water, sugar, and cornstarch. Bring to a boil until it reaches 240 degrees. While waiting for it to boil add the Beetroot powder to the bloomed gelatin.
Pour immediately in the stand mixer, with the mixture on low. Slowly increase to high. Seat until super thick and glossy. Then add in the vanilla and salt, until combined.
Let sit in the fridge for at least 4 hours, or overnight.
Dust with the powdered sugar mixture and cut. I like to cut mine out in heart shapes! Enjoy!
