Ingredients
For the Cake:
- 2 large eggs (at room temperature)
- 1 cup granulated sugar
- ½ cup whole milk
- 5 tablespoons unsalted butter
- 1 cup all-purpose flour (plus 2 tablespoons)
- 1 ¼ teaspoons baking powder
- ¼ teaspoon salt
- 2 teaspoons vanilla extract
For the Pastry Cream:
- 6 egg yolks (at room temperature)
- ⅔ cup granulated sugar
- ¼ cup cornstarch
- 1 tablespoon vanilla extract
- 2 cups whole milk
- 1 tablespoon unsalted butter
For the Ganache:
- ¼ cup heavy cream
- 4 ounces bittersweet chocolate (chopped)
Instructions
- Make the Pastry Cream: In a saucepan, heat the milk and vanilla extract over medium heat until it begins to steam but does not boil. Remove from heat. In a separate bowl, whisk together egg yolks and sugar until pale and slightly thickened. Sift in cornstarch and whisk until smooth. Slowly pour hot milk into the egg mixture a little at a time while whisking constantly to temper the eggs. Strain the mixture back into the saucepan and cook over medium heat, whisking constantly until thick and just bubbling. Remove from heat and stir in butter. Transfer to a bowl, cover with plastic wrap pressed onto the surface, and refrigerate until chilled, about 1–2 hours.
- Prepare the Cake: Preheat oven to 350°F (180°C). Grease and parchment line an 8-inch round cake pan. Whisk together flour, baking powder, and salt in a small bowl. In a large bowl, beat eggs and sugar until pale and fluffy, about 3–5 minutes. Heat milk and butter in a small saucepan until steaming, then stir in vanilla. Gently fold dry ingredients into egg mixture until just combined. Slowly add warm milk mixture, stirring until smooth. Pour batter into the pan, smooth the top, and bake for 30–35 minutes or until a toothpick comes out clean. Cool in pan for 10 minutes, then transfer to wire rack to cool completely.
- Assemble the Cake: Once cooled, slice cake horizontally into two layers. Place bottom layer on serving plate and spread chilled pastry cream evenly over it. Top with the second cake layer and gently press down. Chill the assembled cake in the refrigerator for at least 2 hours to set.
- Prepare the Ganache: Heat heavy cream in a small saucepan until steaming, do not boil. Add chopped bittersweet chocolate, let sit for 2–3 minutes, then stir until melted and smooth. Pour ganache over the chilled cake, spreading gently to the edges so it drips slightly down the sides.
- Final Chill and Serve: Refrigerate cake until ready to serve. Slice and enjoy this rich, classic dessert.
Notes
- Ensure eggs and egg yolks are at room temperature to achieve a smooth, well-incorporated batter and pastry cream.
- Tempering the eggs while making pastry cream prevents curdling and results in a silky custard.
- Press plastic wrap directly onto pastry cream’s surface to prevent a skin from forming during chilling.
- Use an 8-inch round cake pan for ideal cake thickness and layering.
- Allow cake to cool completely before slicing to avoid crumbling.
- For best results, chill assembled cake for a full 2 hours or overnight to enhance flavors and stability.
- Use high-quality bittersweet chocolate for a balanced ganache flavor.
- Store leftovers refrigerated and consume within 3 days for optimal freshness.
