Ingredients Breakdown

For the Shortbread Crust

• 2 cups (250 g) all‑purpose flour
• 1 cup (225 g) unsalted butter, softened
• ½ cup (100 g) granulated sugar
• ¼ tsp salt

For the Vanilla Custard (No‑Bake)

• 2 cups (480 ml) whole milk
• ½ cup (100 g) granulated sugar
• ¼ cup (30 g) cornstarch
• 4 large egg yolks
• 2 tsp vanilla extract
• ¼ tsp cream of tartar (helps set without heat)

For the Whipped Cream Layer

• 1 ½ cups (360 ml) heavy whipping cream
• 2 tbsp powdered sugar
• 1 tsp vanilla extract

For the Chocolate Ganache

• 8 oz (225 g) semi‑sweet chocolate, chopped
• ½ cup (120 ml) heavy cream
• 1 tbsp unsalted butter (optional for shine)

Step‑by‑Step Instructions

1. Prepare the shortbread crust. In a large bowl, combine flour, sugar, and salt. Cut in the softened butter using a pastry cutter or fingertips until the mixture resembles coarse crumbs. Press the dough evenly into the bottom of a 9‑inch springform pan, creating a firm, even layer. Chill for 10 minutes while you work on the custard.
2. Make the no‑bake vanilla custard. In a medium saucepan whisk together milk, sugar, cornstarch, and cream of tartar. Warm over medium heat, stirring constantly, until the mixture thickens (about 5‑7 minutes). Remove from heat and whisk in egg yolks quickly to prevent curdling. Stir in vanilla extract. Transfer the custard to a shallow dish, cover with plastic wrap (direct contact), and refrigerate until firm, about 20 minutes.
3. Whip the cream. Using a chilled bowl and beaters, whip the heavy cream, powdered sugar, and vanilla until soft peaks form. Keep the whipped cream refrigerated.
4. Assemble the first custard layer. Once the custard is set, spread half of it evenly over the chilled shortbread crust, smoothing with an offset spatula.
5. Add the whipped cream layer. Gently pipe or spread the whipped cream over the custard, ensuring an even thickness. This layer creates a light barrier that prevents the chocolate glaze from soaking into the custard.
6. Layer the second custard. Spoon the remaining custard over the whipped cream, smoothing the surface. The contrast between the pale custard and the white cream will be visible after glazing.
7. Prepare the chocolate ganache. Place chopped chocolate in a heat‑proof bowl. Heat the cream in a small saucepan until just simmering, then pour over the chocolate. Let sit 2 minutes, then whisk until glossy and smooth. Stir in butter if using for extra shine.
8. Glaze the cake. Slowly pour the warm ganache over the top of the assembled cake, allowing it to cascade down the sides. Use a spatula to spread any excess and create a smooth finish. The ganache will set as it cools, forming a firm chocolate shell.
9. Chill to set. Refrigerate the fully glazed cake for at least 30 minutes (or up to 2 hours) to allow the ganache to firm and the layers to meld.
10. Release and serve. Run a thin knife around the edge of the springform pan, release the latch, and gently remove the outer ring. Transfer the cake to a serving platter, slice with a hot knife for clean cuts, and enjoy!

Pro Tips & Tricks

Variations & Substitutions

• Gluten‑Free: Substitute the all‑purpose flour with a 1‑to‑1 gluten‑free blend and add 1 tbsp xanthan gum for structure.
• Dairy‑Free Custard: Use full‑fat coconut milk in place of whole milk and a dairy‑free butter substitute for the shortbread. Ensure the chocolate ganache is dairy‑free (use coconut cream).
• Reduced‑Sugar: Replace granulated sugar with an equal amount of erythritol or monk fruit blend; adjust sweetness to taste.
• Flavor Twist: Add 1 tbsp espresso powder to the ganache for a mocha variation, or swirl ¼ cup raspberry puree into the custard for a fruity note.
• Mini Cakes: Divide the batter into 12‑count muffin tins lined with paper; each mini will set faster and serve as elegant bite‑size desserts.

Storage Tips

This layered cake is best enjoyed within 48 hours for optimal texture. Store it in the refrigerator, covered loosely with plastic wrap or a cake dome to prevent the ganache from absorbing odors. For longer storage, wrap the entire cake tightly in aluminum foil and freeze for up to 2 weeks. Thaw in the refrigerator overnight before serving; re‑glaze with a thin drizzle of warmed chocolate if the ganache softens during thawing.
