Happy Friday! It’s the first weekend of spring and I’m looking forward to some fun foodie plans… what about you? I’ve got a culinary tour I’m leading of Chicago’s Chinatown, along with an interactive dim sum class I’m teaching on Saturday. On Sunday, I’m hosting a pre-Easter dinner with friends. So to end the week on a sweet note, here’s a Boston Cream Pie Layer Cake that made not too long ago. The Baron suggested a yellow cake for dessert the other day and rather than a plain cake, I decided to make this. Layers of spongy cake and vanilla custard are stacked and coated with a chocolate glaze frosting for this treat…
For the Yellow Cake:
2 Large Eggs
2 Large Egg Yolks
1/3 cup Buttermilk
2 teaspoons Vanilla Extract
1 3/4 cup All Purpose Flour of Gluten free flour blend* (sifted, then measured & then sifted again)
1 cup Granulated Sugar
1 3/4 teaspoons Baking Powder
1/2 teaspoon Salt
4 tablespoons Unsalted Butter (softened)
1/3 cup Canola Oil
1/2 cup Heavy Cream (whipped to soft peak)
For the Rosemary Orange Pastry Cream:
1 cup Whole Milk
1 cup Heavy Cream
1 sprig Rosemary
4-5 strips (2″) Orange Peel
1/2 cup Sugar
1/4 cup Cornstarch
4 Egg Yolks
2 tablespoons Butter
For the Dark Chocolate Glaze with Orange Liqueur:
9 ounces Bittersweet Chocolate
2 tablespoons Butter
1/2 cup Heavy Cream
1-2 tablespoons Triple Sec
For the Yellow Cake: Preheat oven to 350 degrees F. Grease an 18”x 13” rimmed baking sheet, line it with parchment paper, and then grease the parchment paper too.
In a large measuring cup, combine eggs and vanilla with 2 tablespoons buttermilk.
In a large mixing bowl, combine sifted flour, sugar, baking powder and salt. Whisk well to combine. With the mixer on medium low, beat in the butter, canola oil and the remaining buttermilk into the dry mixture. Stir in the egg mixture in three parts, while scraping down the sides of the mixing bowl. Do not over mix. Fold in the whipped cream into the batter.
Transfer batter onto baking sheet. Use an offset spatula to smooth surface and ensure the batter is an even depth. Bake for about 15 minutes, rotating half-way through baking, until the center is firm when touched.
Allow cake to cool for 5 minutes in pan set on a wire rack. Flip the cake onto a wire rack then immediately re-flip back onto a second wire rack. The cake should be resting with the parchment side down. Allow the cake to cool for another 30 minutes.
For the Rosemary Orange Pastry Cream: In a stainless steel pot, steam milk and cream with rosemary and orange peel.
Combine sugar, cornstarch and salt in bowl. Pour hot cream over and whisk to combine. Return milk mixture to pot and bring to a low boil, continuing to whisk.
In another bowl, whisk eggs and temper 1/2 cup of hot milk mixture into the eggs. Gradually pour this back into the pot and continue to whisk as the mixture comes to a boil. Continue to cook until thick.
Strain through a fine mesh strainer into a clean bowl with pats of butter in the bottom. Stir until butter melts. Chill with plastic wrap directly on top of pudding.
For the Dark Chocolate Glaze with Orange Liqueur: Put the chocolate and butter into a heat proof bowl. Heat heavy cream and triple sec until just hot. Pour hot cream over chocolate and stir until smooth. Let cool slightly before pour over cake.
Putting it all together: Layer cake, pastry cream, cake, pastry cream and third cake. Drizzle chocolate glaze over top of cake and spread to cover the sides of the cake completely.
*Gluten free flour blend:
This is the best combination for my personal uses and has never failed me. I purchased a majority of the ingredients at an Asian market (at less than $.99/lb) and the other ingredients marked were Bob Red Mill brand. Cornstarch was Argo brand.
300 grams superfine brown rice flour (Bob’s Red Mill)
250 grams sweet rice flour (Asian market)
150 grams tapioca flour (Asian market)
100 grams sorghum flour (Bob’s Red Mill)
100 grams potato starch (Asian market)
100 grams cornstarch (Argo brand)
