Egg Yolk Chocolate Chip Cookie Bars

0 Preheat your oven to 350°F and prepare a 9x13” baking pan with non-stick spray and parchment paper
1 In a large bowl, mix your sugars and softened butter until light and fluffy. Beat in your egg yolks and vanilla paste. 
2 Add your flour to the measuring cup and top with your baking soda and powder.  Then pour into your large bowl and stir with a spatula. Mix in your chocolate chips. 
3 Spoon the dough into your baking pan. Use your spatula to evenly spread and flatten the dough. Sprinkle more chocolate chips on top and gently press into the dough. 
4 Bake for 22-28 minutes, or until the edges are lightly browned and the center is not wet. (Mine were done at 22 minutes. So check at around 20 minutes)
5 Allow for the bars to cool before cutting into them. Remove from the pan and place on a wire rack.
