Vanilla Custard Cream Squares

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

2 cups graham cracker crumbs

½ cup unsalted butter, melted

¼ cup granulated sugar

2 cups whole milk

½ cup heavy cream

1 cup granulated sugar

½ cup all-purpose flour

4 large egg yolks

2 teaspoons vanilla extract

Powdered sugar, for dusting

Directions

Preheat the oven to 350°F (175°C).

In a medium bowl, mix the graham cracker crumbs, melted butter, and granulated sugar until well combined.

Press the mixture evenly into the bottom of a greased 9x9-inch baking pan. Bake for 10-12 minutes or until lightly golden and set. Let it cool.

In a saucepan, whisk together the milk, heavy cream, and granulated sugar over medium heat.

In a separate bowl, whisk the egg yolks and flour until smooth. Slowly add a little of the hot milk mixture to the eggs while whisking to temper them.

Gradually pour the egg mixture back into the saucepan, stirring constantly. Cook over medium heat, whisking until thickened and bubbling. Let it boil for 2 minutes, then remove from heat.

Stir in the vanilla extract. Let the custard cool for a few minutes before pouring it over the cooled crust.

Refrigerate for at least 2 hours or until fully set.

Before serving, dust with powdered sugar, slice into squares, and enjoy.

Variations

Chocolate Custard Squares: Replace ¼ cup of the flour with cocoa powder for a chocolate twist.

Citrus Infused: Add a teaspoon of lemon or orange zest to the custard for a refreshing flavor.

Nutty Crunch: Sprinkle finely chopped toasted nuts over the crust before adding the custard.

Coconut Delight: Mix shredded coconut into the custard or sprinkle some on top for a tropical touch.

Gluten-Free Option: Use gluten-free graham crackers for a gluten-free version.

Storage and Reheating

Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days.

Freezing: These squares can be frozen for up to 2 months. Wrap them tightly in plastic wrap and place in an airtight container. Thaw in the refrigerator before serving.

Reheating: These are best enjoyed cold, but if I prefer them slightly warm, I let them sit at room temperature for about 15 minutes before eating.

FAQs

How do I prevent my custard from being lumpy?

Whisking constantly while cooking is key. Also, tempering the egg mixture by adding a little hot milk gradually helps prevent curdling.

Can I make these ahead of time?

Yes, these squares are perfect for making ahead. They need at least 2 hours to set, but I sometimes prepare them the night before for even better results.

What can I use instead of graham crackers for the crust?

Crushed digestive biscuits, vanilla wafers, or even shortbread cookies work well as a substitute.

Can I use low-fat milk instead of whole milk?

Whole milk gives the best creamy texture, but if I want a lighter version, I can use low-fat milk. However, I wouldn't recommend skim milk as it may make the custard too thin.

How do I get clean slices when cutting the squares?

Using a sharp knife and wiping it clean between each cut helps achieve neat, even squares. Chilling the dessert well before slicing also makes a difference.

Conclusion

Vanilla Custard Cream Squares are a simple yet luxurious dessert with a perfect balance of textures. The creamy custard and crunchy graham cracker crust make them an irresistible treat. Whether I’m making them for a party or just to satisfy a sweet craving, they never disappoint.
