Boston Cream Pie Dessert Parfait

I LOVE Boston Cream Pie. There is just something amazingly flavorful that happens when you combine homemade sponge cake, with Bavarian cream and homemade chocolate ganache.

Really I love anything that has the flavors of Boston Cream pie, including the Boston cream donut. My love for Boston Cream pie started when I was a kid. It is my dad’s favorite dessert and I set a goal of creating the best Boston cream pie recipe ever after I got done going to cooking school.

After I created my Boston Cream pie recipe I started branching and getting more creative because there is no such thing as to much Boston Cream and I am going to continue to create fun and tasty variations that include the amazing Boston cream flavors.

What is Boston Cream Pie?

Boston Cream pie is an amazing dessert that is made with 2 layers of sponge cake that is filled with cream or custard and then topped with chocolate ganache or glaze.

For this Boston Cream dessert parfait you don’t have to worry about making layers with a cake since we will be chopping the homemade sponge cake up and layering it with cream and chocolate ganache!

For this Boston Cream Pie Dessert Parfait I used a mason jar as my dish, however you can use a large bowl or a large tall glass. I just love how mason jars look when I am making individual desserts and how they look when they are set out for everyone to enjoy.

How to Make Mason Jar Boston Cream Pie

How to Make Vanilla custard for Mason Jar Boston Cream Pie Parfait

In a medium bowl, whisk together the yolks, sugar and the cornstarch.

In a medium saucepan bring the milk to a gentle boil, be careful it doesn’t boil over.

Remove the pan from the heat and whisk about 1/3 cup of the hot milk into the yolk mixture.

Return the entire mixture to the saucepan.

Over medium-high heat bring the mixture to a boil, whisking constantly for 1 minute. Remove the pan from the heat and whisk until smooth.

Whisk in the butter until melted.

Immediately strain the custard through a fine-mesh sieve into a medium bowl.

Whisk in the vanilla extract.

Cover the surface of the custard with plastic wrap and let cool to room temperature. Refrigerate for two hours, or until well chilled.

Preheat the oven to 350 degrees F.

Grease the bottom and sides of a 9-inch cake pan.

Whisk together the cake flour, baking powder, and salt. Set aside.

In a small saucepan, combine the milk and butter.

Heat over medium heat just until the butter is melted. Remove the pan from the heat and set aside.

In a bowl of an electric mixer using the whisk attachment, beat the eggs at high speed until blended, about 1 minute. Gradually add the sugar and vanilla extract and beat until pale and tripled in volume, about 6 minutes.

Gently fold one-third of the flour mixture into the egg mixture. Repeat with the remaining flour mixture in two more additions.

Reheat the milk mixture to just under a boil.

Add it all at once to the egg mixture and gently fold it in. Scrape the batter into the prepared pan.

Bake the cake for 20-25 minutes, until it springs back when lightly touched and a cake tester inserted into the center comes out clean.

Cool the cake in the pan on a wire rack for 10 minutes. Run a paring knife around the edge of the pan and invert the cake onto the wire rack.

Chocolate Glaze for Mason Jar Boston Cream Pie Parfait

In a small saucepan, bring the cream to a boil.

Remove from the heat and add the chocolate to the pan.

Stir until the chocolate is completely melted and the glaze is smooth.

Stir in the vanilla extract. Transfer the glaze to a small bowl.

Cover the surface of the glaze with a piece of plastic wrap and let cool for about 10 minutes before using.

Transfer the custard filling to the bowl of an electric mixer. Add 1/4 cup heavy cream and using the whisk attachment, beat the mixture at high speed until it is light and forms soft peaks, about 1 minute.

Using a long serrated knife, cut the cake horizontally into 1-inch chunks.

Place a handful of the cake into each mason jar. Top that with a layer of a custard than a layer of chocolate. Repeat this until each jar is full with multiple layers of each item.

Serve the cake immediately, or place the lids on the jars and refrigerate.
