This Boston cream pie cheesecake is the most decadent mashup! With sponge cake, a cream cheese filling, and a chocolate ganache topping, it's to die for.
Preheat the oven to 350 degrees Fahrenheit. Butter a 9-inch springform pan and wrap the outside with foil.
Sift together cake flour, baking powder, and salt.
Beat egg yolks with 1/3 cup sugar until light and ribbony, about 5 minutes. Add vanilla. Fold the flour mixture into the yolk mixture, then blend in melted butter.
In a separate bowl, beat egg whites with cream of tartar until foamy. Gradually add 2 tablespoons sugar, beating until stiff peaks form. Fold the whites into the batter and spread in the pan. Bake for 13-15 minutes.
Make the cheesecake layer. Beat one package of cream cheese with 1/3 cup sugar and cornstarch until creamy. Add remaining cream cheese, then beat in remaining sugar and vanilla.
Blend in the eggs one at a time, then mix in heavy whipping cream.
Pour over the cooled cake layer. Place in a water bath and bake for 75-85 minutes until the center barely jiggles. Cool for 1 hour, then refrigerate for at least 4 hours.
To make the pastry cream, beat the heavy cream, pudding mix, and milk on high until thick. Spread over the chilled cheesecake.
Make the chocolate glaze. Combine chocolate, corn syrup, and butter in a microwave-safe bowl. Heat until melted, stirring until smooth. Cool slightly.
Pour the slightly cooled glaze over the dessert. Serve and enjoy!
