Today is DF’s 47th birthday, every year he asks for the same cake: a Boston Cream pie. the Boston Cream Pie is an oxymoron; it is not a pie in anyway. I have pondered this for years, how did the Parker Hotel, where the first pie/cake originated, decided on two layers of sponge cake with a pastry cream between the layers become known as a pie? During my investigation I found the first pies created included raspberries, chocolate icing and slivered almonds and was referred to as Mrs. Washington pie. Through the years the Boston Cream Pie/ Cake has evolved into the delicious dessert we revere today. Bostonian’s lay claim to the pie/cake as their creation, that being said my version, as most, is based off the Parker House Hotels original recipe.
Sydney and I thought since the recipe is prepared over 2 to 3 days it might be easier to break the posts into three separate posts; the first being the sponge and pastry cream, followed by the assembly, and the chocolate glazed top.
For Sponge Cake:
250 grams egg white, 8 egg whites
1/4-teaspoon egg white powder
140grams egg yolks, about 9 egg yolks
226 grams / 1 1/8-cup super fin sugar divided
Pinch of salt
158 grams/1 1/2-cup cake flour, sifted 3 times
28 grams/1 ounce melted clarified butter, room temperature
Preheat the oven to 180 degrees C/350 degrees F. Spray two 9-inch (one 10-inch) cake pan with baking spray and flour.
Prepare your mise en place. Separate the eggs and divide the sugar into two bowls.
In standing mixer with the whisk attachment place egg yolks and ½ cup of sugar. Whip on medium-high speed till pale, ribbons form, and tripled in volume, set aside.
In a very clean copper bowl of a standing mixer add egg whites, salt, egg white powder and cream of tartar, only if not using a copper bowl. Beat on medium speed till soft peaks form and than add ¼ of sugar. Continue to whip till stiff peaks form, slowly add the last ¼ of sugar, and increase the mixer speed to medium-high. Beat until peaked and very shiny.
Once stiff peaks have been achieved, fold the whites into the yolk mixture a 1/3 at a time.
Gradually sift the flour, 1/3 at a time.
Fold the flour into the eggs with a spatula.
Add about 1/2- cup of the batter to the clarified butter, fold completely, and then add fold back to cake batter.
Pour this mixture into a 10-inch (or 9 inch pans) prepared cake pan. Bake for about 20 minutes, or until spongy and golden. Remove from the oven and allow the cakes to cool in the pans for 15 minutes or until firm.
While the cakes are cooling prepare the pastry cream.
Once the cakes have firmed up transfer to cooling racks for about 1/2 hour, wrap in plastic film, place the cakes and the prepared pastry cream in the refrigerator overnight.
Tune in tomorrow to see how this delectable cake/pie is assembled.
I had no idea it was a three day process. Your layers are thicker than most I’ve seen and I like that. You guys work so well together.
This looks like a more “solid” boston cream cake-which I like. Usually the inside has a pudding like consistency and the top is very runny. The chocolate definitely is different, not sure if the inside filling is due to refrigeration or not. Thanks for sharing this stunning cake and I look forward to seeing more on this. Happy Birthday DF!
From the pictures I see that you have 3 layers of sponge. Is the recipe enough for 3 9″-pans or do you just cut one of the sponges in half?
