Boston Cream Pie From Scratch

This is my first attempt at making a Boston Cream Pie and I nailed it!

That doesn’t aways happen, so excuse me while I brag for a moment. I was certain that this would take a couple of attempts.

If you remember when I shared this Sausage Gravy and Biscuit recipe, I took that day off from my day job so that I would have time to cook some of Alan’s favorite meals for his birthday.

There wasn’t a lot of time to make adjustments, so I’m super glad the baking angels were by my side when I replicated his favorite cake!

I’ve always been too intimidated to make Boston Cream Pie from scratch. It just got in my head that this cake is complicated, so if it happened to be available at our bakery then I would buy it.

Betty Crocker or Duncan Hines also carried (not sure if it’s still available) a boxed cake mix kit that I have made as well, but the cream filling always left me with an aftertaste that I didn’t care for.

Perfect Sponge Cake For Boston Cream Pie

I put on my reading glasses (yes, I’ve succumbed!) and did my research in advance.

As I started to break down the details and look closer at the elements that make this cake.

I learned that I was confident with the ganache and filling, but the sponge cake was what I needed guidance on.

After looking at a bazillion recipes and settled on this Three Ingredient Italian Sponge Cake. What a baking score!

This cake uses only three ingredients just as the title says and it’s fabulous as well as SUPER easy to make!!

The cake came out light and airy and pairs perfectly with the vanilla cream and ganache.

I’ll be making this again and again!

Next time I may substitute the chocolate for strawberries and whipped cream!

Now can anyone tell me why this popular dessert is called a pie?!!

  1. Hi Sandra,

    I have been looking for a simple Boston Cream to make for my dinner party. I would like to make it as two somewhat thinnish sheet cakes and just put one on top of the other instead of trying to slice the cake in half. about

    Do you think a doubling of the ingredients would be enough for one sheet pan and then doubling again for the second pan? I would then proceed with the recipe as directed. Thanks.

  2. The vanilla extract made my filling a bit brown. Any tips on how to prevent that and keep the filling brights? (Without ridding it of vanilla flavor that is)

    1. Hmmm, I know there are clear vanilla extracts that you can purchase. My vanilla extract is homemade. That might make a difference. There is also a powdered vanilla for baking that I’ve used before, but I stopped using it when I noticed that it has fillers added to it. If you are ok with using food colorings a drop or two of yellow will help brighten up the filing. Hope it tasted delicious!

  3. I used to work at Marie Callender’s and I was always in awe of this dessert, I still haven’t attempted to make one. Your recipe makes it look very doable!
