In the bowl of a 5 qt stand mixer, combine 100 grams corn syrup and 2 egg whites. Stir to combine but do not begin whipping.
In a heavy duty thick bottomed pot, combine 600 grams of sugar, 600 grams of corn syrup, 10 grams salt, and 180 grams of water. Stir to combine. Bring to a boil over high heat.
When syrup slurry reaches 234F, begin whipping egg whites on HIGH. DO NOT STOP COOKING SYRUP.
Cook syrup until temperature reaches 254F. Turn off heat.
Very slowly, stream hot syrup into the whipping egg whites. Once all of the syrup is incorporated, whip on high for an additional 4 minutes. Go slow in this step or you will collapse the egg whites.
Turn mixer to low. Add in vanilla, coconut oil, and powdered sugar. Bring back to high for 20-30 seconds to incorporate ingredients.
Layer on top of cooled caramel so the nougat is about ½ inch high. You will have extra nougat and that's okay!
Top nougat with an additional sheet of oiled parchment paper. Cool overnight
