Cook over very low heat, whisking constantly, until very thick, about 5 minutes; do not let boil. Remove from heat. Stir in chocolate and vanilla until melted and smooth. Scrape into a bowl; place plastic wrap directly on the surface. Refrigerate until cold and thickened, at least 2 hours. To assemble: Remove sides of pan from cake. Using serrated knife, cut cake horizontally into 3 equal layers. Place 1 layer on serving plate; spread top with 3/4 cup of pudding. Repeat with remaining layers and pudding.
