CHOCOLATE "CREME EGG" TART

Steps:

• Make the crust:
• Preheat oven to 350°F. Grease tart pan with butter. Pulse cookies and salt in a food processor until cookies are finely ground. With the motor running, slowly pour in melted butter and process until well combined.
• Using a measuring cup, firmly press cookie mixture into bottom and up sides of tart pan. Bake crust until firm, about 10 minutes. Transfer pan to a wire rack and let cool 15 minutes.
• Make the filling:
• Using an electric mixer on medium-high speed, beat corn syrup, cream cheese, butter, vanilla, and salt in a large bowl, scraping down sides of bowl as needed, until combined, 1-2 minutes. Add powdered sugar and beat on low 1-2 minutes, then increase speed to medium and beat until incorporated, 1-2 minutes more. Transfer 1/2 cup filling to a medium bowl. Transfer remaining filling to a pastry or large resealable plastic bag; this is the "egg white" filling.
• Add yellow and red food coloring a few drops at a time to filling in bowl to match the color of an orange egg yolk. Transfer "yolk" filling to another pastry or large resealable plastic bag.
• Make the chocolate ganache and assemble the tart:
• Heat both chocolates in a medium heatproof bowl set over a medium saucepan of barely simmering water (do not let water touch bowl), stirring with a spatula, until chocolate is melted.
• Meanwhile, heat cream in a small pot over medium, stirring occasionally, until warmed through and small bubbles start to appear on the surface.
• Add salt to melted chocolate, then remove from heat and gradually whisk in cream until incorporated. Whisk in butter, then corn syrup, until smooth and combined.
• Pour 1 1/2 cups ganache into cooled crust; reserve remaining ganache in bowl. Chill filled crust until set, about 30 minutes.
• Snip off ends of pastry bags to create a 3/8" hole. Pipe "yolk" filling in a tight spiral in the center of the tart to create an orange "yolk" about 3" wide and 1/2" thick. Pipe "egg white" filling around "yolk" in a tight spiral, about 1/2" thick, leaving about a 1/2" ring of chocolate showing around "egg white" filling at the edges of tart.
• Set bowl with ganache over a pot of barely simmering water; heat ganache, stirring, until it pours easily. Pour over filling until covered; do not overfill. Chill until set, at least 3 hours. Let sit at room temperature 15 minutes before serving.
• Do Ahead
• Tart can be made 1 day ahead. Chill until set, then cover loosely with plastic wrap.
