Instructions
Make The Angel Food Cake
Preheat oven to 175°C.
Beat egg whites in a stand mixer fitted with the whisk attachment on low speed until frothy, about 3 minutes.
Add cream of tartar, vanilla, and salt; increase speed to medium, and beat until mixture is doubled in volume, about 4 minutes.
With the mixer running on medium speed, gradually add granulated sugar, about 12 g at a time.
Beat until meringue is glossy, bright white, and thick enough to form soft, rounded mounds on top of egg white mixture, about 4 minutes. (Stop beating meringue shy of soft peaks.)
Sift cake flour over meringue using a fine mesh strainer; stir once with a rubber spatula just to combine. Fold to fully incorporate flour. (Do not overmix.)
Transfer batter to an ungreased 25 cm footed aluminum angel food cake pan with removable bottom.
Bake in preheated oven until cake is golden brown and bounces back when top is lightly pressed, 40 to 45 minutes.
Invert cake pan to stand on its feet; let cake cool completely, 1 hour and 30 minutes to 2 hours.
Meanwhile, Make The Brown Sugar-Bourbon Cream
Whisk together egg yolks, brown sugar, all-purpose flour, cornstarch, and salt in a small saucepan.
Whisk in milk until well combined. Cook over medium-low, whisking constantly, until mixture thickens and begins to bubble, about 8 minutes.
Continue to cook, whisking constantly, 1 minute.
Immediately pour mixture through a fine mesh strainer set over a medium bowl; discard any solids.
Stir in bourbon and vanilla bean paste. Add butter; stir until melted.
Press a piece of plastic wrap directly onto surface of pastry cream; chill in refrigerator until cold, about 1 hour and 30 minutes.
Run a long, thin knife around pan edge and center tube to release cake.
Lift center tube to remove cake from pan sides; run knife under cake to release it from the pan bottom.
Invert cake onto a serving platter.
To serve, beat heavy cream in a large bowl using a whisk until stiff peaks form, about 4 minutes.
Stir three-quarters of the whipped cream into chilled pastry cream to loosen; fold in remaining whipped cream until just combined.
Cut cake slices using a long, serrated knife or angel food cake cutter, and serve with brown sugar-bourbon cream and berries.
