The BEST Vegan Boston Cream Pie

This is the only recipe for VEGAN Boston cream pie that you will ever need my friends!!!

Isn’t it a beautiful thing? I think it’s a beautiful thing if I do say so myself. Hey, I don’t get credit for how pretty smooth chocolate ganache looks all on its own. I only post recipes after they have been approved by my loyal gang of quality control taste-testers (AKA my family and friends). This recipe has been thoroughly tested and repeated a few times now. It’s a definite keeper.

Why is a Boston Cream Pie Called a “Pie”?

You may have wondered why they call it Boston cream “pie” when it is actually a cake. A very, very yummy cake, but a cake just the same. Well, in the past when cakes became a common thing to bake, pie tins were far more common than cake pans.

The dessert was given its name because cakes and pies were less distinguishable in the middle of the nineteenth century. It became a classic recipe and so the name remains “Boston Cream Pie” and not “Boston Cream Cake” because changing it now would be quite confusing.

What is Different About a Vegan Boston Cream Pie from a Normal One?

A traditional Boston Cream Pie is made with dairy cream, dairy butter, and eggs. A vegan Boston Cream Pie is made with no eggs and no dairy. In order to replace those ingredients the recipe uses vegan “butter”, cornstarch, and plant-based milk to make the custard for the filling. It also uses semi-sweet chocolate that does not contain dairy for the ganache topping. For the cake part you’ll replace the eggs with vegan egg alternatives such as flax seeds, banana, or starch.

How to Make a VEGAN Boston Cream Pie?

The first step to making a vegan Boston Cream Pie is to prepare the cake layers. You will combine ingredients in the proper order, mix, then bake until finished. After that you will cool the cake layers while preparing the rest of the cake.

The second step is to make the custard. Be very careful not to step away as the vegan custard may clump or burn if you don’t continue stirring gently. Once the custard is finished it will need to be cooled.

Step three is assembling the cooled custard and cake layers. You will spread the custard on the base cake layer and carefully top with the other cake layer.

The final step is to melt the ganache ingredients together and pour it over the finished Boston Cream Pie. Lastly, serve it, share it, and enjoy!
