Key Ingredients:
Unsalted butter — the heart of the shortbread crust, melting into the flour to create a tender, crumbly base that holds the custard with quiet strength.
All-purpose flour — simple and dependable, forming a soft, buttery foundation that contrasts beautifully with the smooth cream layer above it.
Egg yolks — rich and golden, they give the custard its velvety body, lending depth, warmth, and that unmistakable homemade character.
Whole milk or heavy cream — the soul of the filling, creating a custard that is lush, silky, and comforting with every chilled bite.
Vanilla extract — the aroma that ties everything together, adding sweetness, floral warmth, and a timeless flavor that feels both gentle and luxurious.
Cornstarch — the quiet stabilizer, ensuring the custard sets into a smooth, sliceable layer without losing its delicate softness.
Powdered sugar — a snowy finishing touch that softens each bite with airy sweetness and elevates the dessert’s elegance.
Expert Tips:
Let the butter truly soften before making the crust, not melted, not cold—just supple enough to cream into a light, airy base. This ensures the shortbread bakes up tender, not dense.
Whisk the custard patiently and constantly, especially as it begins to thicken. Slow, steady stirring prevents lumps, protects the yolks from scrambling, and gives the custard its signature silky finish.
Use medium heat, never high, when cooking the custard. Gentle heat allows the starch to bloom and the eggs to thicken without curdling, creating a smooth, luxurious texture.
Strain the custard through a fine sieve before spreading it on the crust if you want an extra level of smoothness — a small step that makes the final squares feel professionally made.
Let both layers cool thoughtfully, allowing the crust to settle after baking and the custard to rest before chilling. Rushing can cause condensation or an uneven set.
Chill the finished dessert long enough, preferably overnight. The flavors deepen, the texture firms, and cutting becomes clean and effortless.
Wipe your knife between slices, especially if you want perfectly sharp, bakery-style squares. A clean blade preserves those picture-perfect edges.
Dust with powdered sugar right before serving, so it stays bright and delicate instead of melting into the custard.
How to make Vanilla Custard Cream Squares
Ingredients
Shortbread Crust
1 cup unsalted butter, softened
1/4 cup granulated sugar
2 cups all-purpose flour
A pinch of salt
Vanilla Custard Filling
3 large egg yolks
1/2 cup granulated sugar
2 tablespoons cornstarch
2 cups whole milk or heavy cream
1 teaspoon vanilla extract
A pinch of salt
Topping
Powdered sugar, for dusting
Instructions
1. Preheat and Prepare the Pan
Preheat the oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper, leaving extra overhang on the sides to help lift the bars out later.
2. Make the Shortbread Crust
Cream the softened butter and sugar together until light and fluffy, about 2–3 minutes.
Add the flour and a pinch of salt, mixing only until the dough comes together.
Press the dough evenly into the lined pan.
Bake for 15–18 minutes, or until the edges look lightly golden.
Set aside to cool slightly while you make the filling.
3. Prepare the Vanilla Custard Filling
In a medium saucepan, whisk together the egg yolks, sugar, and cornstarch until smooth and lump-free.
Slowly pour in the milk (or cream), add the pinch of salt, and whisk until fully combined.
Cook over medium heat, stirring constantly, until the custard thickens and begins to gently bubble, about 5–7 minutes.
Remove from the heat and stir in the vanilla extract.
Let the custard cool for a few minutes.
4. Assemble and Chill
Spread the warm custard evenly over the baked crust.
Tap the pan on the counter to release any trapped air bubbles.
Allow it to cool to room temperature, then refrigerate for at least 2 hours (or overnight) until completely set and firm.
5. Cut and Serve
Lift the chilled custard slab out of the pan using the parchment overhang.
Dust generously with powdered sugar.
Slice into squares and enjoy as is — or serve with berries, whipped cream, or a drizzle of caramel for an extra treat.
Important Notes When Making Vanilla Custard Cream Squares
Temperature matters at every step — softened butter creates the right crust texture, gentle heat keeps the custard creamy, and a full chill ensures the bars slice cleanly and hold their shape.
The crust should be lightly golden, not deeply browned; overbaking it can make the base too firm and compete with the delicate custard. Aim for a pale, tender shortbread that supports without overpowering.
The custard will thicken suddenly near the end, so stay attentive. Once it bubbles softly and coats the back of a spoon, it’s ready—going past this point may make it grainy.
If using heavy cream instead of milk, the custard will be noticeably richer and denser; choose milk for a lighter feel or cream for a more luxurious bite.
Vanilla quality makes a difference. Pure vanilla extract or vanilla bean paste adds warmth and depth that elevates the entire dessert.
Allow enough chilling time, as the custard needs hours to fully set. Cutting too early may cause it to slump or squash into the crust.
Humidity can affect powdered sugar, sometimes causing it to dissolve. Dust right before serving for the prettiest presentation.
Store the squares covered in the refrigerator, as the custard is delicate and absorbs nearby odors easily—airflow or strong-smelling foods can alter the flavor.
How to Enjoy This Dish Vanilla Custard Cream Squares After Cooking
Let the chill fully settle before your first bite. These custard squares are at their best when the cold has tightened the creamy layer and softened the shortbread just enough. That first cool, velvety bite should feel refreshing and luxurious.
Slice with intention. Use a warm, clean knife for each cut to create sharp edges that highlight the contrast between the buttery crust and silky custard. Presentation matters with a dessert this delicate.
Dust generously with powdered sugar right before serving. This adds a soft sweetness and visual elegance, like fresh snow settling on the surface. It melts slowly with each bite, giving a gentle lift to the custard’s richness.
Pair each square with something gentle. A handful of fresh berries, a spoonful of whipped cream, or a thin ribbon of caramel can elevate the experience without overwhelming the subtle vanilla notes.
Savor slowly. The beauty of this dessert lies in its simplicity — the buttery crumble, the cool custard, the warmth of vanilla. Take small bites and let the textures unfold: the initial firmness, the melting softness, the delicate sweetness.
Serve with a warm drink for contrast. A cup of hot tea, a mild coffee, or even warm milk creates a soothing balance to the chilled dessert, making each bite even more comforting.
Share it chilled, not room temperature. These squares soften as they warm, so keep them cool until the moment you’re ready to enjoy or serve them. The crisp edges and clean layers are part of their charm.
Enjoy within 2–3 days. The custard tastes freshest during this window, and the shortbread stays tender without becoming soggy. Over time, the custard absorbs moisture and loses its delicate texture.

Frequently Asked Question:
Can I make the custard filling ahead of time?
Yes. You can prepare the custard up to 24 hours in advance. Press plastic wrap directly on the surface to prevent a skin from forming, then refrigerate. Before assembling, whisk it briefly to restore smoothness.
Why did my custard turn lumpy or grainy?
Lumps typically form when the heat is too high or the custard is not whisked constantly. To rescue it, pass the warm custard through a fine mesh sieve — it will instantly smooth out and improve the final texture.
Can I use vanilla bean or vanilla bean paste instead of extract?
Absolutely. Vanilla bean paste gives a deeper, more aromatic flavor and beautiful specks of vanilla throughout the custard. Use the same amount as you would extract for a more luxurious result.
How do I prevent the crust from becoming too hard?
Avoid overbaking. The crust should be pale golden, not deeply browned. Overbaked shortbread turns firm and can overpower the custard’s delicate texture. Remove it as soon as the edges show light color.
Why do my squares collapse or slide when I cut them?
This happens when the custard is not fully chilled. The dessert needs at least 2 hours — preferably overnight — to set completely. For clean slices, use a cold sharp knife and wipe it between each cut.
How do I know when the custard has thickened enough?
The custard is ready when it coats the back of a spoon and leaves a clean line when you swipe your finger across it. It should bubble gently—not vigorously—and feel silky, not runny. Overcooking can make it grainy, so remove it from the heat as soon as it thickens.
My shortbread dough feels too crumbly. What should I do?
Lightly press and fold the dough with your hands. The warmth of your palms helps the butter bond with the flour. Avoid adding water — shortbread should be firm but cohesive. If it still won’t hold together, the butter may have been too cold; let the dough rest at room temperature for 5 minutes.
How can I prevent the custard from forming lumps while cooking?
Constant whisking is key. Keep the mixture moving from the moment you turn on the heat until you see gentle bubbles. Using medium heat allows the cornstarch to thicken steadily without shocking the egg yolks.
Can I bake the crust and assemble everything later?
Yes. You can bake the crust up to one day ahead. Let it cool completely, then cover it well to prevent dryness. Assemble with the warm or reheated custard when you’re ready — the custard will adhere better if it’s not cold.
My custard layer looks uneven. How do I fix that?
After spreading the custard, tap the pan firmly on the counter several times. This releases trapped air, smooths the surface, and helps the custard settle into a clean, even layer before chilling.
