Directions for No-Bake Custard Slice

Ready to create this creamy treat? Let’s layer it up!

Prepare Pan

I line an 8×8-inch square pan with parchment paper, leaving overhang for easy removal.

Layer Base Biscuits

I arrange a single layer of graham crackers or digestive biscuits to cover the pan’s bottom, breaking pieces to fit if needed.

Make Custard

In a saucepan, I whisk 4 cups milk, ½ cup sugar, and ⅓ cup cornstarch until smooth. I heat over medium, stirring constantly, until hot. I slowly whisk in 3 egg yolks, stirring for 5–7 minutes until the custard thickens. Off the heat, I stir in 2 tbsp butter and 2 tsp vanilla extract until fully combined.

Assemble Layers

I pour half the custard over the biscuit layer, spreading evenly. I add another biscuit layer, pour the remaining custard, and top with a final biscuit layer.

Add Icing and Chill

I mix 1 cup powdered sugar, 1–2 tbsp milk, and ½ tsp vanilla extract until smooth, then spread over the top biscuit layer.
I chill the No-Bake Custard Slice in the fridge for at least 4 hours, preferably overnight, to set.
I slice into squares and serve this chilled Summer Dessert.
