Stir in eggs 1 at a time, and then stir in vanilla. Stir in flour mixture until just incorporated, do not overmix.
3. Divide batter between pans. Use an offset spatula to spread batter into thin, even layers. Bake, rotating pans once, until batter just begins to set, 8-10 minutes. The surface will look dry, and testers inserted in the center wil come out wet. Let cool completely in pans on wire rack.
4. To assemble, place the flat side of a lare wire rack over 1 brownie, and invert rack, brownie, and pan together. Remove pan and parchment. Repeat with remaining brownie. Place a clean rimmed baking sheet over 1 brownie, and invert pan, brownie, and rack together. remove rack. The brownie should be in the pan, top side down.

8. Prepare an ice-water bath. Uncover cream mixture, and reheat until hot but not boiling. Whisk egg yolks, sugar and salt in a large bowl. Add cream mixture in a slow steady stream, whisking constantly until well combined. Return mixture to saucepan, and stir constantly over medium heat until thick enough to coat the back of a spoon, about 8 minutes. Do not let the mixture come to a simmer.
9. Strain through a fine sieve into a bowl. Discard solids. Set the bowl in the ice-water bath. Stir in vanilla, and let cook, stirring occasionally, until cold, about 20 minutes.
