Why You'll Love This Recipe
About the Ingredients
1 cup (125g) all-purpose flour
Provides structure for the crust. Substitute with gluten-free all-purpose flour if needed.
1/2 cup (115g) unsalted butter, softened
Adds richness and tenderness. Use salted butter and reduce added salt if you prefer.
1/4 cup (50g) granulated sugar
Sweetens the crust. You can use coconut sugar for a deeper flavor.
1/4 teaspoon salt
Enhances flavors. Omit if using salted butter.
1 cup (240ml) whole milk
Creates a creamy filling. Substitute with 2% or oat milk for a lighter option.
2 large egg yolks
Thickens the custard filling. Use pasteurized eggs if serving to young children.
1/4 cup (50g) granulated sugar
Sweetens the filling. Adjust to taste.
2 tablespoons cornstarch
Thickens the filling without a floury taste. Can use arrowroot powder.
1 teaspoon vanilla extract
Adds warmth and flavor. Use pure vanilla for best results.
1/4 teaspoon ground nutmeg (optional)
Adds a classic spice note. Use cinnamon for a different twist.
Tips & Tricks
- For a crisp crust, pre-bake it for 8-10 minutes before adding the filling.
- Whisk the filling constantly while heating to prevent lumps and a scorched bottom.
- Let the dessert cool completely before cutting so the filling sets properly.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prepare Pan
Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal.
2. Make the Crust
In a bowl, mix flour, 1/4 cup sugar, and salt. Cut in softened butter until crumbly. Press evenly into the pan. Bake for 10 minutes until lightly golden.
3. Whisk the Filling
In a saucepan, whisk milk, egg yolks, 1/4 cup sugar, cornstarch, vanilla, and nutmeg until smooth.
4. Cook the Custard
Heat over medium heat, stirring constantly, until thickened and bubbling, about 5-7 minutes. The custard should coat the back of a spoon.
5. Pour Over Crust
Pour the hot custard over the baked crust. Spread evenly.
6. Bake the Dessert
Bake for 15-20 minutes until the edges are set and the center is slightly jiggly. The internal temperature should reach 170°F (77°C).
7. Cool and Serve
Let cool completely on a wire rack, then refrigerate for at least 2 hours. Cut into squares and serve chilled.
Delicious Variations
- Add 1/2 cup of chocolate chips to the filling for a chocolate twist.
- Top with fresh berries or a dollop of whipped cream before serving.
- Swap the nutmeg for cinnamon and add a pinch of cardamom for a spiced version.

Frequently Asked Questions
Q: Can I make this School Lunch Dessert ahead of time?
Yes, you can make it a day ahead and store it in the fridge. This dessert actually tastes better after it has chilled, making it perfect for meal prep.
Q: Can I use a gluten-free flour for the crust?
Absolutely, you can substitute the all-purpose flour with a 1:1 gluten-free flour blend. The texture will be slightly different but still delicious.
Q: How do I know when the custard is done?
The custard is done when it thickens and coats the back of a spoon, and when the internal temperature reaches 170°F (77°C). It will continue to set as it cools.
Q: Can I use low-fat milk instead of whole milk?
