2 1/2 teaspoons pure vanilla extract or vanilla bean paste
2 cups all-purpose flour
1 teaspoon salt
1 cup vanilla baking chips, divided (you can use white chocolate chips)
10-12 Golden Oreos or vanilla sandwich cookies of choice, broken into large pieces.
Preheat oven to 350F. Lightly grease a light metal 9x13 baking pan.
Vanilla Wafer Crust
Mix together melted butter, vanilla, and crushed cookies and press into the prepared pan, using the bottom of a glass or ramekin to really pack the crumbs in tight. Bake crust on center rack for about 10 minutes and allow to cool.
In a saucepan, melt the butter on low heat and then remove from heat and add the vanilla chips. Cover and let stand for 5 minutes, and then stir until chips are melted and the mixture is smooth. Allow to cool.
In another bowl, beat eggs, sugar and vanilla.
Mix in the butter and vanilla mixture along with the flour and salt. Mix until just combined. Pour the batter over the cooled vanilla wafer crust. Top with the Golden Oreo cookie pieces.
Bake at 350 for 30-35 minutes, until top is golden and a toothpick comes out with a few moist crumbs. Oven time may vary, do not over bake.
Place remaining vanilla chips into the corner of a plastic Ziploc bag. Microwave in 30 second increments, kneading chips with your hands after each one, until melted. Use scissors to snip off a tiny corner of the bag and drizzle the vanilla over the top of the bars.
