Boston Cream Pie Burger (บอสตันครีมพายเบอร์เกอร์)

1.Spread unsalted butter on the burger buns and bake at 200°C for about 3 minutes, or until the surface is slightly crisp. Let cool.

2.Prepare the custard by whisking egg yolks and sugar together. Add cornstarch and whisk again, followed by vanilla extract and milk. Stir until smooth. Cook over low heat, stirring continuously until thickened. Remove from heat, add unsalted butter, and mix well.

3.Transfer the custard into a bowl over an ice bath to cool, then place into a piping bag.

4.Pipe custard onto one burger bun and cover with another. Repeat for the second piece.

5.For the chocolate ganache, place dark chocolate and whipping cream in a microwave-safe bowl. Heat in 30-second intervals, stirring each time, until melted and smooth. Let cool slightly, then drizzle over the assembled burger. Allow to set before serving.
