‘Boston Cream Pie’ (or should I say cake) … this dessert is actually a cake but it is called a pie just due to the fact that back in the day when this recipe was developed cakes were actually baked in pie tins. It is an amazing combination of airy sponge cake, generous amount of silky pastry cream and chocolate glaze.

If you want to bake a simple yet elegant cake for a special occasion like a birthday or anniversary with minimum time and mess in the kitchen this is your cake. The best part is that you can prepare the pastry cream ahead of time (1 to 2 days) and store it in the fridge.  With very basic ingredients and less effort you can make this amazing treat for you family and friends.

I baked this cake for my husband’s birthday last week. As I had the pastry cream already sitting in my fridge it hardly took me 40 minutes (Including Baking time) to bake him his birthday cake. He loved it and to be honest it was hard to stop at one piece.

There are three parts to this recipe. We will start with the pastry cream  followed by the cake  and then the chocolate glaze.

Pastry Cream for Boston Cream Pie


  • 1/4 cup sugar
  • 3 large egg yolks
  • 2 tablespoon all purpose flour
  • 2 tablespoon constarch/cornflour
  • 1 1/4 cup milk
  • 1 teaspoon pure vanilla essence

Cooking Directions

  1. In a heat proof bowl mix the egg yolks and sugar together.
  2. Sift the cornflour and flour together and then add it into the egg mixture and mix until you get a smooth paste.
  3. In a saucepan heat the milk until just boiled. Pour the milk very slowly into the egg mixture whisking constantly to avoid curdling of the eggs. whisking constantly is very important (if you feel that some of your eggs have curdled don’t worry you can strain the mixture to get rid of lumps).
  4. Now when you have a smooth mixture pour it into the saucepan and return to heat. whisking constantly cook the mixture for 2 to 3 minutes of medium to low heat. This will allow the flour and cornflour to thicken the pastry cream to a spreadable consistency.
  5. When the pastry cream is thick enough take of heat and transfer it to a clean bowl to avoid further cooking from the hot sauce pan. Stir in the vanilla essence and allow it to cool.
