Ingredients
For the Cake:
- 6 tablespoons butter, softened: Adds richness and tenderness to the cake.
- 2 tablespoons all-purpose flour: Combines with cake flour for structure.
- 1 ½ cups cake flour: Creates a light, fluffy texture.
- 2 teaspoons baking powder: Helps the cake rise.
- ¼ teaspoon salt: Balances the sweetness.
- ¾ cup white sugar: Sweetens the cake.
- 2 eggs: Provide structure and moisture.
- 1 teaspoon vanilla extract: Enhances the cake’s flavor.
- ½ cup milk: Keeps the batter moist and smooth.
For the Custard Filling:
- ½ cup light cream: Adds richness to the custard.
- ½ cup milk, divided: Thins the custard and aids in cooking.
- ¼ cup white sugar: Sweetens the filling.
- 1 pinch salt: Enhances the flavors.
- 4 teaspoons cornstarch: Thickens the custard for a creamy texture.
- 2 eggs: Create a smooth, custardy consistency.
- ½ teaspoon vanilla extract: Adds warmth to the filling.
For the Chocolate Glaze:
- 3 (1-ounce) squares semisweet chocolate: Forms the rich, glossy topping.

- ¼ cup light cream: Thins the glaze for pouring.
- ½ cup confectioners’ sugar: Sweetens and thickens the glaze.
- ½ teaspoon vanilla extract: Enhances the chocolate flavor.
Why These Ingredients Matter
- Cake Flour: Ensures a tender, light cake that contrasts the dense custard.
- Custard: The creamy, vanilla-infused filling is the heart of the pie, providing richness.
- Semisweet Chocolate: Creates a glossy, decadent glaze that ties the dessert together.
- Eggs: Essential for structure in both the cake and custard, ensuring a cohesive texture.
Substitutions and Variations
- Cake Flour: Substitute with 1 ¼ cups all-purpose flour + ¼ cup cornstarch for a similar texture.
- Light Cream: Use half-and-half or whole milk for a lighter custard and glaze.
- Semisweet Chocolate: Swap with dark or milk chocolate for a different flavor profile.
- Cornstarch: Replace with 2 tablespoons flour for the custard, though cornstarch yields a smoother result.
- Vegan Option: Use vegan butter, plant-based milk, a flax egg substitute (1 tbsp flaxseed meal + 3 tbsp water per egg), and vegan chocolate.
- Gluten-Free: Use a gluten-free cake flour blend and ensure cornstarch is gluten-free.
Instructions
Step 1: Preheat and Prep
- Preheat your oven to 375°F (190°C).
- Grease and flour two 9-inch round cake pans.
- Sift together 2 tablespoons all-purpose flour, 1 ½ cups cake flour, 2 teaspoons baking powder, and ¼ teaspoon salt. Set aside.
Tip: Sifting the dry ingredients ensures a light, airy cake with no lumps.
Step 2: Make the Cake Batter
- In a deep bowl, cream 6 tablespoons softened butter with ¾ cup white sugar until light and fluffy, about 2-3 minutes with a mixer.
- Beat in 2 eggs, one at a time, ensuring each is fully incorporated.
- Mix in 1 teaspoon vanilla extract.
- Add the flour mixture alternately with ½ cup milk in three additions (flour, milk, flour, milk, flour), beating until smooth after each addition.
- Divide the batter evenly between the two prepared pans.
Tip: Scrape down the bowl to ensure even mixing for a uniform cake texture.
Step 3: Bake the Cakes
- Bake at 375°F (190°C) for 15 minutes, or until the cakes begin to shrink from the sides of the pans and the centers spring back when lightly touched.
- Remove from the oven and turn the cakes onto wire racks to cool completely.
Tip: Run a knife around the edges before inverting to prevent sticking.
Step 4: Make the Custard Filling
- In a saucepan, combine ½ cup light cream and ¼ cup milk. Heat over medium until bubbles form around the edges, but do not boil.
- Stir in ¼ cup white sugar and a pinch of salt until dissolved. Remove from heat.
- In a small bowl, whisk ¼ cup milk with 4 teaspoons cornstarch until smooth. Add 2 eggs and whisk to combine.
- Gradually pour the hot cream mixture into the egg mixture in a thin stream, whisking constantly to temper the eggs.
- Return the mixture to the saucepan and bring to a boil over low heat, stirring constantly. Cook until thickened and smooth, about 5 minutes.
- Remove from heat, stir in ½ teaspoon vanilla extract, and let cool to room temperature, stirring occasionally to prevent a skin from forming.
Tip: Place plastic wrap directly on the custard surface while cooling to avoid a skin.
Step 5: Make the Chocolate Glaze
- In a heavy saucepan over low heat, melt 3 (1-ounce) squares semisweet chocolate with 2 tablespoons butter, stirring until smooth.
- Remove from heat and gradually stir in ¼ cup light cream in a thin stream, mixing until smooth.
- Add ½ cup confectioners’ sugar and beat vigorously until glossy.
- Stir in ½ teaspoon vanilla extract.
Tip: If the glaze thickens too much, gently reheat over low heat and add a splash of cream.
Step 6: Assemble the Pie
- Place one cooled cake layer on a serving plate or cake stand.
- Spread the cooled custard filling evenly over the cake, leaving a slight border around the edges.
- Place the second cake layer on top, pressing gently to secure.
- Pour the chocolate glaze over the top, allowing it to drip down the sides for a dramatic effect.
Tip: Work quickly with the glaze to ensure an even, glossy finish before it sets.
Step 7: Chill and Serve
- Refrigerate the pie for at least 1 hour to set the custard and glaze.
- Slice into 12 wedges and serve chilled or at room temperature.
Tip: Use a sharp knife dipped in hot water for clean slices through the custard and glaze.
