Vanilla Custard Cream Squares

If you’ve ever craved something creamy, cool, and not too fussy, Vanilla Custard Cream Squares are a quiet little win. Think: flaky pastry, soft vanilla custard in the middle, and a simple glaze on top. No bells or whistles. Just a tidy dessert that slices neatly and feels right at home after dinner—or with a cup of coffee. This version leans classic: puff pastry sheets, a stovetop custard, a short chill, and clean squares that hold together when you lift them from the pan. Nothing fancy, just good, familiar flavors that settle in nicely.

Ingredients for this Vanilla Custard Cream Squares

Makes about 12 squares

For the pastry layers

• 2 sheets frozen puff pastry, thawed (about 9–10 inches/23–25 cm square each)

For the vanilla custard

• 3 cups (720 ml) whole milk
• 1/2 cup (120 ml) heavy cream
• 2/3 cup (130 g) granulated sugar
• 6 large egg yolks
• 6 tablespoons (48 g) cornstarch
• 2 teaspoons pure vanilla extract (or 1 vanilla bean, split and scraped)
• 3 tablespoons (42 g) unsalted butter, cubed
• Pinch of fine salt

For the glaze

• 1 cup (120 g) powdered sugar
• 2–3 tablespoons milk (or water), plus a drop of vanilla if you like
• Optional: 2 teaspoons warmed raspberry jam for a swirl on top

Optional finishes

• Fresh berries for serving
• Extra powdered sugar for dusting

Instructions

1) Bake the pastry

Preheat your oven to 400°F (200°C). Line two baking sheets with parchment. Unfold each puff pastry sheet and place one on each tray. Prick all over with a fork (this helps them bake flatter). Lay another sheet of parchment on top and set a second baking tray over each to weigh them down slightly. This keeps the pastry from puffing too tall.

Bake for 15–20 minutes, until golden and crisp. Remove the top trays and parchment for the last 3–5 minutes if you want a touch more color. Cool completely on a rack.

2) Make the custard

In a medium saucepan, warm the milk and cream over medium heat until steaming (not boiling). If using a vanilla bean, add the seeds and pod to the milk now; fish out the pod later.

In a separate bowl, whisk the sugar, egg yolks, cornstarch, and salt until thick and smooth. It should look a bit pale and glossy. Slowly pour in about 1 cup of the hot milk while whisking—this tempers the eggs and keeps them from scrambling. Then whisk the tempered mixture back into the saucepan with the remaining milk.

Cook over medium heat, whisking constantly, until the custard thickens and starts to bubble—about 3–5 minutes after it comes up to temperature. Go slowly and keep whisking the corners of the pot. When it’s thick like pudding, take it off the heat. Whisk in the butter and vanilla extract (if not using a bean). Let it sit for 5 minutes, then press plastic wrap directly on the surface to prevent a skin.

3) Assemble

Line an 8×8-inch (20×20 cm) square pan with parchment, leaving overhang on two sides for easy lifting. Trim the baked pastry sheets to fit. Place one pastry layer in the bottom of the pan.

Give the custard a quick whisk to smooth it out. Spread it evenly over the pastry, nudging it into the corners. Top with the second pastry sheet, gently pressing to level it.

4) Chill and glaze

Cover and chill for at least 3 hours, or until the custard is fully set. Overnight is even better if you can wait.

For the glaze, whisk the powdered sugar with just enough milk to make a thick but pourable icing. Spread it over the top pastry. If you’re using jam, warm it slightly, dot a few small spoonfuls on the glaze, and drag a toothpick through for a casual swirl. Let the glaze set, 20–30 minutes.

5) Slice and serve

Lift the slab out with the parchment overhang and place it on a cutting board. Use a long, sharp knife. For the cleanest cuts, warm the knife under hot water, wipe it dry, and slice straight down—no sawing. Cut into 9 large or 12 smaller squares. Serve chilled, with berries if you like. Breathe. Enjoy.

Little friendly tips

• If the custard looks lumpy, whisk vigorously off heat—or press it through a fine mesh sieve. It’ll smooth out.
• Humidity can soften pastry. Keep the finished squares chilled and uncovered for the first hour, then cover lightly.
• Want more vanilla? Add 1/4 teaspoon vanilla bean paste to the glaze. Subtle, but lovely.

Frequently asked questions

Can I make Vanilla Custard Cream Squares ahead?

In fact, they’re better the next day. Assemble and chill overnight, then glaze a few hours before serving so the top stays pretty. They keep well for 2–3 days in the fridge. The pastry will soften a bit over time, but the flavors settle in beautifully.

What if I don’t have puff pastry?

You’ve got options. Graham crackers make a quick no-bake version: line the pan with crackers, add the custard, then top with more crackers and chill. You can also use flaky crackers (like soda crackers) for a retro icebox vibe. The texture is different—more tender than crisp—but still very good.

My custard was runny. What went wrong?

Usually it’s one of three things: not enough cornstarch, not cooking it long enough after it thickens, or not chilling it fully. Make sure you measure the cornstarch level (not scant), cook until the custard bubbles and holds its shape, and chill for at least 3 hours. If it’s borderline, the fridge is your friend—extra time helps it set.

One last note: this dessert doesn’t try to impress. It just shows up, layered and calm, ready when you are. Slice, share, tuck the leftovers into the fridge. Tomorrow, when the day gets long, you’ll be glad it’s waiting.
