Ingredients:
- 3/4 cup (150g) Granulated sugar
- 1/3 cup (40g) Cornstarch
- 1/2 tsp (3g) Fine sea salt
- 3 cups (710ml) Whole milk
- 4 Large egg yolks, room temperature
- 2 tbsp (28g) Unsalted butter
- 2 tsp (10ml) Pure vanilla extract
- 11 oz (312g) Vanilla wafers
- 6 Medium bananas, firm but speckled
- 1 tsp (5ml) Fresh lemon juice
- 2 cups (475ml) Heavy whipping cream, cold
- 1/2 cup (60g) Powdered sugar
- 1 tsp (5ml) Pure vanilla extract
Instructions:
- In a heavy-bottomed saucepan, whisk together granulated sugar, cornstarch, and fine sea salt until well combined.
- Gradually whisk in the whole milk over medium heat. Continue stirring until the mixture begins to steam.
- In a separate medium bowl, lightly beat the egg yolks. Slowly drizzle one cup of the hot milk mixture into the yolks while whisking constantly to temper the eggs.
- Pour the tempered yolk mixture back into the saucepan. Whisk vigorously over medium heat until the custard thickens and large bubbles begin to pop on the surface.
- Remove from heat and stir in the unsalted butter and 2 teaspoons of vanilla extract until smooth.
- Immediately pour the hot custard through a fine-mesh sieve into a clean bowl to ensure a silken texture. Cover the surface directly with plastic wrap to prevent a skin from forming.
- In a large bowl using an electric mixer, beat the cold heavy whipping cream, powdered sugar, and remaining 1 teaspoon of vanilla until stiff peaks form.
- Slice bananas and lightly toss with lemon juice to prevent browning. In a trifle dish or 9x13 pan, create layers starting with vanilla wafers, followed by banana slices, and then the custard base.
- Top the final layer with the stabilized whipped cream. Refrigerate for at least 4 hours to allow the wafers to soften into a cake-like consistency.
