Is Boston Cream Pie a Pie?

Surprisingly Boston cream pie isn’t a pie at all. Instead, this stunning dessert is made with two layers of moist vanilla cake, encasing a delicious, lightly sweetened custard and finished with a dark chocolate ganache glaze.

So no, it is not a pie, this gluten-free dessert is a cake. But if you are looking for a pie with custard, you may enjoy the Gluten-Free Coconut Lemon Custard Pie or the Coconut Crème Brûlée.

This Boston cream pie is made mainly with milk. Yes, 3 1/2 cups of milk. The recipe may look complicated, but it is sooo easy to make. It took me 20 minutes of prep time to put this gluten-free dessert together.

easy steps to make gluten-free Boston cream pie

To not overwhelm you, I will break down the steps of making this Boston cream pie recipe. The recipe may look complicated because of the long instructions, but it’s not.

gather all the ingredients

Get the ingredients ready for the recipe.  What I love about this Boston cream pie recipe is the ingredients are basic pantry things. Milk, eggs, butter, vanilla, sugar, baking powder, and to keep the flours simple, I used a gluten-free all-purpose flour blend.

The only ingredient you may have to get is tapioca flour/starch, but you can also use corn starch. The glaze is also easy, chocolate and cream.

make the custard first because it needs to cool

Begin with the custard. The custard needs to cool, so that is why I started with the custard. First, you heat the milk with sugar. Then, in a separate bowl, whisk the remaining custard ingredients.

Next, add some hot milk to the bowl, pour the mixture into the remaining hot milk, cook until it thickens, then cool—nothing to it.

make the cake batter 

Super easy! Whisk the eggs with sugar and salt until light and thick. This is pretty standard with most cake recipes. In a small saucepan, heat the milk until very hot but not boiling. Remove from the heat, stir in butter until melted and then vanilla.

Slowly pour the hot mixture into the eggs while the mixer runs, then fold in the dry ingredients. Done! Pour the mixture into the baking pans and bake.

prepare the chocolate ganache glaze

You will need two ingredients. Good gluten-free chocolate or chocolate chips and cream. Using a double boiler, heat the cream and chocolate until the chocolate has melted. About 3 minutes. Done!

assemble the Boston cream pie

This is the fun part. Spread the custard over the bottom cake, top with the second cake and pour the chocolate glaze over the top. Then refrigerate the cake for a minimum of two hours, allowing the cake to set. Done!

1 or 2 cake pans for the cake?

I like to simplify things, so I used two 8-inch round cake pans. If you don’t have 8-inch cake pans, you can use one 9-inch round cake pan and split the cake into two layers after cooled. You may need to bake the cake a few minutes longer until it passes the toothpick test. 

plan ahead when making Boston cream pie

You need to allow time for chilling. The custard needs time to set and become firm enough for slicing, so plan ahead when making this dessert.

How to slice the cake?

For slicing the Boston cream pie, yyou will need a sharp knife and very hot water. Resting your knife in a jug of hot water in between slices will give you a perfect slice of cake.
