Step-by-Step Instructions to Make Boston Cream Cake
To craft a delicious Boston cream cake, follow these steps diligently. Ensure to gather all ingredients and tools before starting.
Making the Pastry Cream
Begin with the pastry cream. In a medium saucepan, whisk together 2 cups of whole milk, 1/2 cup of granulated sugar, and 1/4 teaspoon of salt.
Bring to a simmer over medium heat. In a separate bowl, whisk 5 large egg yolks together with 1/4 cup of cornstarch until smooth. Gradually mix the hot milk into the egg yolk mixture.
Return the mixture to the saucepan and cook over medium heat, stirring constantly until thickened. Remove from heat, stir in 2 tablespoons of unsalted butter and 1 teaspoon of vanilla extract.
Cover with plastic wrap, pressing it directly on the surface to prevent a skin from forming, and refrigerate until fully chilled.
Preparing the Cake Layers
Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large mixing bowl, cream 1/2 cup of unsalted butter with 1 cup of granulated sugar until light and fluffy.
Add 3 large eggs one at a time, beating well after each addition. Mix in 1 teaspoon of vanilla extract. In another bowl, sift together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/2 teaspoon of baking soda.
Alternately add the dry ingredients and 1 cup of buttermilk to the butter mixture, beginning and ending with the flour mixture.
Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Cool the cakes in the pans for 10 minutes, then remove from pans and cool completely on wire racks.
Assembling the Cake
Once the cake layers and pastry cream are ready, start assembling the cake. Place one cake layer on a serving plate. Spread the chilled pastry cream evenly over the top of the cake layer.
Place the second cake layer on top, pressing gently to set. Refrigerate the assembled cake for at least 30 minutes to firm up the pastry cream.
Creating the Chocolate Ganache
For the chocolate ganache, heat 1 cup of heavy cream in a saucepan over medium heat until it just begins to simmer. Place 8 ounces of chopped semisweet chocolate in a heatproof bowl.
Pour the hot cream over the chocolate and let it sit for 5 minutes to melt. Stir until smooth and glossy. Let the ganache cool slightly before pouring it over the chilled cake.
Allow the ganache to drip down the sides of the cake naturally. Refrigerate the cake until the ganache sets. Serve chilled.
Tips for Success
Here are some effective and practical tips for making a cream cake recipe successfully:
Consistent Measurements
Accurate measurements ensure the cake’s quality. Use a kitchen scale for precise flour and sugar amounts. Measure liquids in a clear measuring cup at eye level.
Proper Mixing Techniques
Mix ingredients uniformly. For the cake batter, mix until just combined to avoid dense texture. Incorporate air by whisking well when making custard.
Chilling Time
Chill the custard thoroughly. Rest in the refrigerator for at least 2 hours before assembling. Ensure the cake layers cool completely to prevent melting the custard.
Ganache Consistency
Achieve smooth ganache by using high-quality chocolate. Heat cream to just boiling, pour over chocolate, and let sit before stirring. Stir until glossy.
Assembly Precision
Layer evenly for stability. Spread custard between cake layers uniformly. Apply gentle pressure to avoid spilling. Chill the assembled cake for at least 1 hour before adding ganache.
Serving Temperature
Serve the cake chilled. The flavors meld better, and the texture is firmer. Store leftovers in the refrigerator, covered to retain moisture.
Storing and Freezing
Proper storage ensures a Boston cream cake maintains its quality, flavor, and texture.
Storing
To store a Boston cream cake, place it in an airtight container to prevent it from drying out. Keep the cake refrigerated, especially if it contains perishable ingredients like custard and ganache. Stored this way, it can last up to 3-4 days without losing its freshness.
Freezing
For longer storage, freezing the Boston cream cake is an option. Ensure the cake is completely cool before wrapping it in plastic wrap, followed by aluminum foil for an extra layer of protection.
When ready for use, thaw the cake in the refrigerator overnight; this preserves its moisture and texture. Cakes can be frozen for up to 2 months, but consuming it sooner ensures better flavor.
