Boston Cream Pie

Ingredients:
yellow cake mix, prepared according to directions
For the pastry cream:

• 1/2 tbsp butter
• 1 cup whole milk
• 1 cup whipping cream
• 6 tablespoons sugar (upon further review we've added another tablespoon of sugar)
• 2 tablespoon cornstarch
• 3 eggs
• 1 or 2 teaspoons vanilla extract, or to taste
• big pinch of salt

For the chocolate ganache:

• 4 ounces high-quality dark chocolate, preferably bittersweet
• 1/2 cup cream
• 1 teaspoon butter

A Boston cream pie is all about the cream and ganache. In fact, here's a tip in case you want to take that idea and run with it – instead of two cakes, just use one. Use a long, serrated knife to split the cake in two, and proceed with the recipe as shown.
