This cream puff cake is a showstopping dessert that combines the flaky, buttery layers of puff pastry with a luscious vanilla pastry cream and a cloud of whipped cream. It’s a clever, deconstructed take on the classic French cream puff, but made infinitely easier by using store-bought puff pastry. The result is a crisp, creamy, and elegant cake that looks like you spent hours on it, yet comes together with minimal fuss—perfect for birthdays, holidays, or any celebration.
Ingredients
- 1 sheet (about 9.5 oz / 270 g) frozen puff pastry, thawed
- 2 cups (480 ml) whole milk
- 1/2 cup (100 g) granulated sugar, divided
- 4 large egg yolks
- 1/4 cup (30 g) cornstarch
- 1 teaspoon vanilla extract
- 1 1/2 cups (360 ml) heavy cream, cold
- 1/4 cup (30 g) powdered sugar, plus more for dusting
- 1 teaspoon vanilla extract (for whipped cream)
- Optional: fresh berries or chocolate shavings for garnish
Instructions
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- On a lightly floured surface, roll the thawed puff pastry sheet slightly to smooth out the creases. Cut it into two equal rectangles. Place both on the prepared baking sheet and prick them all over with a fork to prevent excessive puffing.
- Bake for 12–15 minutes, until golden brown and fully puffed. If they puff unevenly, gently press them down with a spatula. Let cool completely on a wire rack.
- While the pastry bakes, make the pastry cream. In a medium saucepan, heat the milk and 1/4 cup (50 g) of the sugar over medium heat until steaming but not boiling.
- In a separate bowl, whisk the egg yolks with the remaining 1/4 cup (50 g) sugar until pale and thick. Whisk in the cornstarch until smooth.
- Slowly pour about 1/2 cup of the hot milk into the yolk mixture, whisking constantly to temper it. Then pour the yolk mixture back into the saucepan with the remaining milk.
- Cook over medium heat, whisking continuously, until the mixture thickens and comes to a gentle boil. Boil for 1 minute, then remove from heat. Stir in the 1 teaspoon vanilla extract.
- Transfer the pastry cream to a bowl, cover with plastic wrap directly on the surface to prevent a skin from forming, and refrigerate until completely chilled, at least 2 hours.
- Once the pastry cream is cold, make the whipped cream. In a large chilled bowl, beat the heavy cream, powdered sugar, and 1 teaspoon vanilla extract until stiff peaks form.
- Gently fold the whipped cream into the chilled pastry cream in two additions, until fully combined. This is your cream puff filling.
- To assemble: Place one baked pastry rectangle on a serving platter. Spread the cream filling evenly over the top. Place the second pastry rectangle on top, pressing gently.
- Dust generously with powdered sugar. If desired, top with fresh berries or chocolate shavings. Refrigerate for at least 1 hour to set before slicing.
Tips
- Use cold heavy cream: For the whipped cream to reach stiff peaks, the cream and bowl should be very cold. Chill your mixing bowl and beaters in the freezer for 10 minutes before whipping.
- Don’t skip pricking the pastry: Fork pricks allow steam to escape, preventing the pastry from ballooning into uneven shapes. If it still puffs unevenly, gently press it down after baking.
- Make sure the pastry cream is fully chilled: Folding whipped cream into warm pastry cream will deflate it. Wait until the pastry cream is completely cold (at least 2 hours in the fridge).
- Substitution: If you don’t have cornstarch, use 1/2 cup (60 g) all-purpose flour instead. The texture will be slightly less glossy but still delicious.
Serving Suggestions
Serve this cream puff cake chilled, straight from the refrigerator. It’s wonderful on its own, but you can elevate it with a drizzle of warm chocolate sauce, a spoonful of berry compote, or a dusting of cocoa powder. For a festive touch, arrange fresh raspberries or sliced strawberries on top just before serving. Pair it with coffee or espresso for an afternoon treat, or with a glass of dessert wine for a special occasion.
Variations
- Chocolate Cream Puff Cake: Add 4 oz (115 g) melted dark chocolate to the pastry cream after it thickens, and fold in as it cools.
- Lemon Cream Puff Cake: Replace the vanilla extract in the pastry cream with 2 teaspoons of lemon zest and 1 tablespoon of lemon juice. Add a thin layer of lemon curd between the pastry layers if desired.
- Fruit-Filled Version: Spread a layer of sliced strawberries or peaches on top of the pastry cream before adding the top pastry layer.
- Almond Puff: Sprinkle sliced almonds over the top pastry before baking, and add a few drops of almond extract to the pastry cream.
Storage and Reheating
Store the assembled cream puff cake in the refrigerator, covered loosely with plastic wrap or in a cake carrier, for up to 3 days. The pastry will soften slightly over time, which is normal and still delicious. Do not freeze the assembled cake, as the cream filling will separate upon thawing. If you have leftover baked pastry rectangles, they can be stored in an airtight container at room temperature for up to 2 days and re-crisped in a 350°F (175°C) oven for 5 minutes. The pastry cream alone can be made a day ahead and kept refrigerated, covered, for up to 3 days.
Frequently Asked Questions
Can I use puff pastry that has already been rolled into a circle?
Yes, you can use any shape of puff pastry. Just adjust the cutting accordingly—you want two equal-sized layers. If using a round, you’ll get a round cake, which is lovely.
Why did my pastry cream turn lumpy?
Lumps usually happen when the eggs are added too quickly to the hot milk, or when the mixture isn’t whisked constantly. To fix it, strain the pastry cream through a fine-mesh sieve before chilling.
Can I make this cake ahead of time?
Absolutely. Assemble the cake up to 24 hours in advance, but wait to dust with powdered sugar until just before serving to keep it looking fresh. The pastry will soften a bit, which many people actually prefer.
Is it okay to use low-fat milk?
You can use 2% milk, but the pastry cream will be less rich and slightly thinner. Whole milk gives the best texture and flavor.
What if I don’t have a thermometer for the pastry cream?
You don’t need one. The pastry cream is done when it visibly thickens and starts to bubble gently. Boil for one minute to ensure the cornstarch is fully cooked.
Can I use whipped topping instead of heavy cream?
Yes, you can substitute 2 cups (480 ml) of thawed frozen whipped topping for the homemade whipped cream. Fold it into the pastry cream the same way. The taste will be sweeter and less rich.
