Boston cream pie !

“In Boston they ask, how much does he know? In New York, how much is he worth? In Philadelphia, who were his parents?” – Mark Twain.

Yup, its called a pie but its really cake !


Wikipedia tells me it is because this cake came into being a long time back when cakes and pies were made in similar pans ! 

Boston cream pie is two layers of yellow or vanilla cake ,  filled with custard or pastry cream and topped with a shiny glaze. I have made it before and found it really heavy and sweet. Good, but heavy and sweet. 

This time around, I played it with a little bit. I made a Boston cream pie layer cake (this dessert is going to have an identity crisis for sure !)I chose a sponge that is really light – which is my hot milk sponge cake . I layered the cake and soaked it generously with some simple syrup. I used vanilla pastry cream for the filling but lightened it by folding in a little whipped cream.And i topped it with some dark chocolate ganache – perfect against all that sweetness !

If you havent tried the hot milk sponge cake yet, you should give it a go. Its a great basic vanilla cake- with the lightness of a traditional sponge cake but with a little structure like that of a butter cake. You can eat it plain but I prefer using it in layer cakes. You can make it in a bigger pan and slice in two with the pastry cream slathered in between. Speaking of pastry cream , or creme pastisserie which is its official name , its a thick custard based on milk or cream and eggs with a little flour for thickening. I have a go-to recipe for pastry cream that has yolks but since I didnt want to have spare egg whites lying around, in this cake I used a cream that uses one egg and makes a small quantity. 

Like I was saying , I folded some whipped cream into the pastry cream, so you get the flavour of the pastry cream  but it is light and fluffy . I covered the cake with it before pouring on just-made ganache. You can whip in more cream if you want to pipe , or you can use the pastry cream itself without the cream. You can also set the ganache and ice the cake instead of just pouring it on. As usual, I couldnt wait !

It sounds simple and probably looks plain – but let me  tell you – DELICIOUS !

  5. It is done when you dip a spoon and run your finger along the back of the spoon, there is a clear path.
  6. Stir in the butter and vanilla.
  7. Strain (optional) into a bowl. Cover the top with plastic wrap so that it touches the surface of the cream.

Notes
  1. This cake needs to be refrigerated and tastes good for atleast 4 days.
  2. To make the most of your time , make the cake. As the cake bakes, you can make the pastry cream. Prepare the simple syrup before assembling the cake and the ganache as the cake chills after the crumb coat.
  3. The simple syrup and whipping cream is optional.
  4. My measuring cup is 240 ml.
  5. The finished cake weighs about 1 kg or a little more.
FLOURS & FROSTINGS http://floursandfrostings.com/

I just love it when its all about the cake . This cake has no frills – just good strong flavours. It tasted really yum when served cold but if you decide against soaking it , do let it come to room temperature. The cake is fluffier but so light and so good!
