My Decadent Boston cream pie cake 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!

Nick’s favorite 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 Boston cream pie cake 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 for Boston cream pie cake?

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.

Hi Nick, Thanks for this video. Looks so delicious. Question: Can I use custard powder instead of eggs for the custard recipe? Do you think it will come out the same way? Thanks in advance for your response. keep safe!

Hi Sharls! Thanks so much for watching! I haven’t tried that, but think it would turn it into a much thicker custard. I’d say give it a go. If it comes out too thick you can always thin it out with a dash of warm milk. N x

I can’t wait to try this!!!!! It brings me so much lovely memories of when I first tried Boston cream doughnuts from one of the franchises that opened up in my home country! I even worked with them for 4 years! I live in Malta 🇲🇹 so 20 years ago it was something I had never tried!!! Unfortunately we don’t have this franchise anymore and no one really makes similar authentic doughnuts like I remember!!

Custard tasted awful! There was so much raw flour taste! No matter how long I was cooking and stir it again and again. I baked it with twice more milk and it did help a bit. I suggest using 20 g. cornstarch instead. And yep, I haven’t checked the rest of the recipe after this mess 🙁

I’ve made this recipe loads of times and I haven’t had that problem. And the custard is not baked. It’s cooked on the stove. I’ve also had lot’s of people tell me they enjoyed the recipe. I stand by this recipe 100% for those reasons and I would encourage anyone reading this to follow the recipe.

I LOVE YOUR RECIPES!!! Do you think this could be made into a two tiered cake and hold up as a wedding cake?

Hi Nivia! Hmm, it’s a sponge cake so you would need to make sure you have a properly support structure built for it. But I don’t see why not! And thanks for the kind words! N x

WOW! first attempt at a Scran line recipe after many years following on FB. What a recipe to start with. The custard was absolutely amazing, cooked it slowly on the hob and had no flour taste at all. I did splash out and buy the vanilla paste instead of just essence and it really made a difference. I also used whole milk (UK) so not sure if this made a difference. Will defo be trying more recipes, in love with this one!
