Preheat oven to 350 degrees and place oven rack in center position. Cover a baking sheet with parchment paper and set aside.

In a bowl, use a hand mixer to combine eggs, oil, sugar and vanilla. Mix well, add flour one cup at a time, mixing until well combined between additions. Dough should look and feel like cookie dough.

Add white chocolate and mix by hand until well distributed in the dough

Split the dough in half and form into two long "bars" so to speak (see photo) Bar should be long enough to make it no more than 3/4 high (see photos)

Place 1 1/2 tablespoons granulated sugar into a small bowl. Add 1 teaspoon vanilla and mix. Then use half of the cinnamon sugar to sprinkle on both cookie bars.

Bake at 350 for 25 minutes. Remove form oven and turn oven temp down to 325. Use a sharp knife to slice the dough into 1/2" pieces, turn on their sides and sprinkle with remaining cinnamon sugar. (see photos)

Place back in the oven and bake for 25 more minutes. Remove and allow to cool. Store in a covered container for up to a week.
