Ingredients
1 1/2 sticks unsalted butter, melted, plus more for baking sheets
1 cup plus 2 tablespoons unbleached all-purpose flour
3/4 teaspoon kosher salt
1 cup sugar
3 large eggs, room temperature
2 teaspoons pure vanilla extract
2 pints vanilla ice cream, softened
1/2 pint raspberry sorbet, softened
Preparation
Preheat oven to 350°F. Butter two 9-by-13-inch rimmed baking sheets. Line each with parchment, leaving an overhang on two long sides; butter parchment. Whisk together flour and salt.
In another bowl, whisk together butter, sugar, eggs, and vanilla extract. Whisk in flour mixture until smooth. Divide batter evenly between sheets; bake until dry to the touch, 12 to 14 minutes. Transfer sheets to wire racks; let cool completely.
Using a 1 1/2-inch star cutter, stamp out 12 evenly spaced stars (3 rows of 4, about 3 inches apart) from one cake; discard or reserve for snacking. Beat ice cream and sorbet separately until spreadable; spread ice cream over uncut cake in an even layer. Dollop sorbet over ice cream; swirl with the tip of a knife. Top with stamped cake, top-side up.
Wrap in plastic (still in sheet); freeze at least 8 hours and up to 1 week. Transfer cake to a cutting board; cut into 12 sandwiches with a serrated knife. Serve immediately.
