Separate the egg yolks from the whites.
In a stand mixer, pour the egg whites. Using the general mixer attachment, mix on medium-high until aerated. Then add ¼ cup of the sugar by the spoonful. Continue mixing until soft peaks are formed.
In a large bowl, beat the egg yolks until they are pale. Add the second ¼ cup of sugar, vanilla, and salt to the beaten yolks.
Take the egg whites and fold them into the yolks bit by bit. When this is mixed evenly, sift the flour and corn starch directly into the mixture and fold it all in.
Preheat the oven to 350℉
Once everything is well combined, you can fill a piping bag with the mixture. Cut a rather large opening and pipe onto a baking sheet lined with parchment paper. Pipe into 4 inch by 1 inch logs with generous amount of space between. Once all are piped, dust with powdered sugar.
Bake at 350℉ for 12 to 15 minutes or until lightly golden. They should be a bit firm to the touch.
Let cool and serve!
