Boston Cream Pie (II)
This Boston Cream Pie recipe features a simple vanilla cake filled with homemade pastry cream and topped with a chocolate ganache.
Six years ago, I made my grandma a Boston cream pie for her 91st birthday when she requested something that involved “white cake and pudding”. It was the first time I had made Boston cream pie from scratch, and as it turned out, that was the last birthday that we were able to celebrate with her, so the pie-that-is-really-a-cake holds a special place in my heart.ย You can see my rendition of that original cake here (please excuse the absurdly awful pictures!); it was a sponge cake filled with homemade pastry cream and covered in a silky chocolate glaze.
It was good, but in retrospect I thought it could be better. I wanted the best Boston cream pie recipe I could muster. So, when I asked my husband if there was anything in particular he’d like for dessert on Easter and he said “Boston cream pie”, it was my chance to make a new and improved version. Here it is!
So, total disclaimer (that I’m sure I’ve mentioned before) – I’m really not much of a white/vanilla cake person. I’m not a huge cake fan in general, so if I DO eat it, I really, really prefer that it be chocolate. However, there is an exception. I don’t need much convincing when it comes to Boston cream anything because..ย I mean, pastry cream and chocolate?ย DONE!
Alright, here’s the rundown of how I put this cake together…
Sponge cake does absolutely nothing for me, so I nixed that in favor of my favorite yellow cake recipe. I used the same pastry cream filling from the original recipe because I’ve made it countlessย times for a ton of different things, and it’s always perfect. If it’s not broke, right? As for the chocolate, I prefer Boston cream pies that have exposed sides and just chocolate on top for more of a casual/rustic look. I ditched the glaze in favor of my favorite ganache (used on my peanut butter cup cake) and let it thicken up a little more than usual, although you could totally pour it on and let it slide down the sides – it would be equally gorgeous!
I served this alongside my fresh strawberry pie for dessert on Easter and it was a huge hit. A couple of other cake-averse family members loved it, which sealed the deal for me!

Boston Cream Pie
Ingredients
For the Pastry Cream
- 2 cups (473.18 ml) half-and-half
- ยฝ cup (100 g) granulated sugar
- Pinch salt
- 5 large egg yolks
- 3 tablespoons cornstarch
- 4 tablespoons cold unsalted butter, cut into 4 pieces
- 1ยฝ teaspoons (1.5 teaspoons) vanilla extract
For the Cake
- 2ยผ cups (281.25 g) all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- ยฝ cup (113.5 g) unsalted butter, at room temperature
- 1ยฝ (1.5) cups granulated sugar
- 3 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1ยผ cups (300 ml) buttermilk
For the Chocolate Ganache
- 8 ounces (226.8 g) semisweet chocolate, finely chopped
- ยพ cup (178.5 ml) heavy cream
Instructions
- Make the Pastry Cream:ย Heat the half-and-half, 6 tablespoons of the sugar, and the salt in a medium heavy-bottomed saucepan over medium heat until simmering, stirring occasionally to dissolve the sugar.
- Meanwhile, whisk the egg yolks in a medium bowl until thoroughly combined. Whisk in the remaining 2 tablespoons sugar and whisk until the sugar has begun to dissolve and the mixture is creamy, about 15 seconds.ย Whisk in the cornstarch until combined and the mixture is pale yellow and thick, about 20 seconds.
- When the half-and-half mixture reaches a full simmer, gradually whisk the simmering half-and-half into the yolk mixture to temper.ย Return the mixture to the saucepan, scraping the bowl with a rubber spatula; return to a simmer over medium heat, whisking constantly, until a few bubbles burst on the surface and the mixture is thickened and glossy, about 30 seconds.ย Off the heat, whisk in the butter and vanilla.ย Strain the pastry cream through a fine-mesh sieve set over a medium bowl.ย Press plastic wrap directly on the surface to prevent a skin from forming and refrigerate until cold and set, at least 3 hours or up to 2 days.
- Make the Cake:ย Preheat oven to 350 degrees F. Grease and flour two 9-inch round cake pans; set aside.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt; set aside.
- Using an electric mixer, cream together butter and sugar until light and fluffy, about 3 to 5 minutes. Scrape down the sides of the bowl and beat in the eggs, one at a time, beating for 1 minute between each addition. Beat in vanilla extract.
- Add the dry ingredients all at once and beat on low speed until just combined. Add the buttermilk and beat on low for 1 minute, then increase the speed to medium and beat for 3 additional minutes.
- Divide the batter evenly between the prepared pans. Bake for 25 to 35ย minutes, or until a skewer inserted into the center of the cake comes out with just a few moist crumbs attached. Remove from the oven and cool for 10 minutes in the pans, then turn out onto wire racks and cool completely before assembling.
- Make the Ganache:ย While the cake cools, make the chocolate ganache. Place the chocolate in a 4-cup measuring cup; set aside. Place the cream in a small saucepan over medium heat and warm until it just comes to a boil. Pour the cream over the chopped chocolate and let sit for 2 minutes. Begin whisking the mixture in the center, gradually working your way outward until the ganache is completely smooth. Set aside to cool, whisking occasionally, until it has thickened slightly, yet still a pourable consistency.
- Assemble the Cake: Place one of the cake layers on a serving platter, then spread the pastry cream evenly over top. Place the second cake layer on top and pour the chocolate ganache into the center of the cake layer. Using an offset spatula, gently spread the ganache into an even layer over the top of the cake. Refrigerate until ready to serve.
Notes
- This cake can be prepared up to 1 day in advance and should be kept in the refrigerator.
- Half and half is a common dairy product in the U.S. but can be replaced with 50% whole milk and 50% heavy cream.

Boston Cream Pie II looks absolutely irresistible โ that creamy filling and rich chocolate topping are a perfect match! Have you tried making it from scratch or followed this recipe exactly?
Made the Boston Cream Pie to the T! AMAZING!!!! We made it again it was THAT good! Love this cake!
Easy to make. Hard to keep together. I learned if you use the side of a spring form pan it will all stay in place and set better. Really good though.
I made this over the weekend. I follow the directions to the letter. Overall, the cake is moist and flavorful, the pastry cream is delicious, the ganache complimented the flavors of the cake and the pastry cream. However, like others, the pastry cream oozed out between the cake layers, and was just a mess. When adding the chocolate ganache it just created more of a mess because the pastry cream was everywhere. Not sure that I will keep this recipe in my repertoire without tweaking it a bit.
I found the post to be exceptionally informative, and I greatly appreciate the shared insights.

I made this cake. It is sweet and yummy. I can enjoy it while playing bloxd io
A Boston Cream Pie is never two full layers. It is a 1 layer cut into 2 layers, with a glaze, never ganache. Well, that’s if you are looking for a traditional Boston Cream Pie.
And this cake recipe is a standard yellow cake, hardly a vanilla cake.
There are MANY versions of this recipe so chill out, buttercup.. Take a pill…..
This is my go-to recipe when I want an impressive dessert. ย Iโve never had to strain my pastry cream as itโs smooth and too thick to strain. I line the same size cake pan with plastic wrap, pour the pastry cream in pan, press another plastic wrap to top to prevent a film and refrigerate over night. ย
After baking/cooling the cakes in the morning, the pastry cream easily turns out of the pan on to the bottom layer. ย Presto! A perfect puck of pastry cream! Be sure to line the pan or the cream will stick to the bottom and make a mess.
For the ganache, I use a better quality chocolate ( in a shiny wrapper) and have never had a consistency issue. ย Thanks again for making me look talented! ๐
Thank you for the suggestion of putting the filing in a cake pan! Genius!
