Boston Cream Pie Cake

My Decadent Boston cream pie is made with a soft vanilla sponge cake, silky smooth vanilla pastry cream and topped with my delicious, one-bowl glossy chocolate sauce! This classic American cake is such a treat, so easy to make and a perfect example of the simple things in life, being so good!

Nicks favourite thing…

It’s always the simple things in life that are the most enjoyable. And this cake is no exception. This cake is easy to make, delicious and so classic. And just an FYI, I would classify this dessert as something you’d find at a country fair. Those are my favourite types of desserts! No fuss, not fancy, just really delicious!

What does it taste like?

The sponge is soft and light and really easy to make. The custard filling is a creamy, easy to make classic pastry cream speckled with thousands of vanilla beans. And to top it off, a glossy and perfectly silky chocolate ganache.

What are the ingredients I need?

Milk – I used cos milk, but almond milk will also work.

Unsalted butter – salted would work well too.

Caster sugar – also known as superfine sugar.

All-purpose flour – also known as plain flour.

Eggs – you’ll need egg yolks for the custard and whole eggs for the cake. I used large eggs. If you’re looking for ways to use up the left over meringues, check out my Passionfruit Pavlova here, my Fairy bread Pavlova here, and my Strawberry Pavlova here! !

Vanilla bean paste – you can use vanilla extract in its place. Always use good quality vanilla extract when baking, it makes a huge difference. I have a great recipe here for it if you’d like to try your own!

Heavy cream – this is the type of cream you use for whipping.

Baking powder – this is used to help the cake rise.

Salt – I used fine salt.

Dark chocolate – I used nestle dark chocolate melts.

Glucose syrup – also known as corn syrup.

Let’s go through each step.

  1. Add the next layer of cake and gently press down.
  2. Finish by pouring the chocolate ganache on top.

My Top Tips!

  • When pouring the ganache, make sure the ganache is not too warm or thin or it will drizzle off the cake and look messy. You want it just thin enough that it will gently and slightly fall off the sides. Refer to the video to see what I mean.
  • Make the custard first to give it enough time to chill and set.
  • Make the ganache about 30 minutes before pouring to allow it to come to the right consistency.
  • When adding the custard, use a spatula to spread around and flatten out as much as you can. Alternatively, you can use a spoon.
