Ingredients

4 large eggs
3/4 cup granulated sugar
1 teaspoon vanilla extract
1/2 cup vegetable oil
3/4 cup milk
1 1/2 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt

For the Custard Filling:

2 cups whole milk
1/2 cup granulated sugar
1/4 cup cornstarch
1/4 teaspoon salt
4 large egg yolks
2 tablespoons unsalted butter
2 teaspoons vanilla extract

For the Whipped Cream Topping:

1 cup heavy whipping cream

Step-by-Step

Preheat your oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper for easy removal.
Make the cake layer: In a large bowl, whisk together 4 eggs and 3/4 cup sugar until pale and thick. Stir in 1 teaspoon vanilla extract and 1/2 cup vegetable oil, mixing until well combined. Add 3/4 cup milk.
Sift in 1 1/2 cups flour, 2 teaspoons baking powder, and 1/4 teaspoon salt. Mix just until no streaks remain—don’t overmix, or the cake may turn dense.
Pour the batter into the prepared pan and smooth the top. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.
While the cake cools, prepare the custard: In a medium saucepan, whisk together 2 cups milk, 1/2 cup sugar, 1/4 cup cornstarch, and 1/4 teaspoon salt over medium heat until the mixture starts to steam.
In a small bowl, lightly beat 4 egg yolks. While whisking constantly, slowly pour some hot milk mixture into the yolks to temper them. Then, pour the warmed yolks back into the saucepan, whisking nonstop.
Cook, whisking constantly, for 3–4 minutes or until the mixture thickens considerably. Remove from heat. Stir in 2 tablespoons butter and 2 teaspoons vanilla until smooth.
Spread the warm custard evenly over the cooled cake layer. Let it cool to room temperature, then refrigerate for at least 1 hour until set.
For the topping, beat 1 cup heavy whipping cream until soft peaks form. Spread the whipped cream over the chilled custard layer.
Chill again if needed, then slice into neat squares. Wipe your knife between cuts for perfect edges.

What to Serve Vanilla Custard Cream Squares With

Vanilla Custard Cream Squares are delicious all on their own, but you can elevate them with a few thoughtful pairings. Serve them alongside a mug of hot coffee, cappuccino, or dreamy chai latte for a relaxing snack. If you’re planning a party, pair with fresh mixed berries, a scoop of vanilla ice cream, or even a drizzle of caramel or chocolate sauce for that extra wow factor. For a full dessert table, set them next to Lemon Drizzle Bars or Chocolate Mousse Cups for a lovely array of flavors and textures.

Top Tips for Perfecting Vanilla Custard Cream Squares

Measure ingredients carefully for both cake and custard layers to ensure the perfect texture.
Use whole milk for a richer, creamier custard, but you can substitute almond or oat milk for a dairy-free version.
To prevent lumps in your custard, whisk constantly and temper the egg yolks gradually.
Chill the dessert for at least an hour (or even overnight) for easier slicing and better flavor.
For an extra touch, add a dusting of powdered sugar, a grating of chocolate, or sliced strawberries on top before serving.

Storing and Reheating Tips

Vanilla Custard Cream Squares are best enjoyed fresh but can be stored in the refrigerator for up to 3 days. Keep them in an airtight container to prevent the cake from drying out and the custard from absorbing fridge odors. If needed, you can freeze the squares (before adding whipped cream) wrapped tightly in plastic and stored in a freezer-safe box for up to one month. Thaw overnight in the fridge and add fresh whipped cream before serving. Don’t microwave to reheat; instead, let them come to room temperature naturally to preserve their luscious texture.
