Atlantic Blueberry Vanilla Cream Puff

This Atlantic Blueberry and Vanilla Bean Cream Puff Cake is what I reach for when I want a true showstopper layered cake that still feels light and seasonal. The pâte à choux bakes up golden and delicate, then gets stacked with clouds of true vanilla bean cream and ribbons of wild blueberry compote. It always earns a collective gasp when brought to the table, but every bite is pure comfort.

The first time I made this for a summer birthday, everyone assumed I had ordered it from our favorite patisserie—nothing compares to homemade. Now it is the cake my sister requests for every celebration.

Ingredients

• All-purpose flour: gives structure and sturdiness to the choux layers for reliable puff
• Unsalted butter: ensures rich flavor and just the right tenderness in the pastry
• Large eggs: create the signature airy texture in cream puffs—choose very fresh eggs for best lift
• Heavy cream: makes the filling lush and holds soft peaks beautifully
• Vanilla bean or paste: brings the deepest most aromatic vanilla notes—splurge on a real bean if you can
• Mascarpone cheese: if you use it adds a subtle tang and helps the whipped cream stay sturdy
• Atlantic blueberries: deliver bright jammy sweetness—choose plump berries without wrinkles
• Lemon juice: sharpens the blueberry compote and balances creaminess
• Powdered sugar: sweetens and finishes the layers elegantly
• Cornstarch: thickens the blueberry compote for spoonable texture

Step-by-Step Instructions

Prepare the Choux Pastry:

Bring water butter and a pinch of salt to a boil in a saucepan over medium heat until the butter is fully melted and bubbles form around the edges

Quickly add all-purpose flour and stir fast with a wooden spoon until the dough forms a single ball and pulls away from the sides of the pan this is key for the right puff

Let the dough cool out of the pan for several minutes so it does not scramble the eggs when you add them

Beat in eggs one at a time fully incorporating each you want a dough that drops from a spoon in thick ribbons and has a slight sheen

Scoop or pipe the dough into two even eight inch rounds on a baking sheet lined with parchment leaving room for the dough to expand

Bake at a steady heat until deep golden puffed and crisp so the pastry will hold up to the filling allow layers to cool fully before assembling

Prepare the Blueberry Compote:

Combine blueberries sugar and lemon juice in a small saucepan over medium heat bringing out the berries juices

As fruit simmers stir in the cornstarch mixed with water and continue to cook just a few minutes until the sauce is thick enough to coat a spoon

Cool the compote completely so it does not melt the cream during assembly

Whip the Vanilla Bean Cream:

In a large chilled bowl use an electric beater to whip heavy cream scraped vanilla beans or paste and powdered sugar to soft peaks for lightness

Gently blend in mascarpone if using until completely smooth and the mixture is billowy

Assemble the Cake Layers:

Set one cooled cream puff layer on a white plate then spread half the vanilla cream evenly covering to the edges

Spoon blueberry compote generously over the cream with some juicy berries at every slice

Top with the second pastry layer pressing gently so the cake holds together

Finish with the rest of the cream and a few dots of compote plus plenty of fresh blueberries and a light dusting of powdered sugar

Save

The mascarpone cream is my favorite part because it stays fluffy all day and never weeps even in warm weather It reminds me of picnics growing up with bowls of whipped cream and berries This cake always brings back that easy joy

Storage Tips

This cake is best enjoyed fresh the same day but you can bake choux layers and make the compote ahead Store cooled choux wrapped airtight at room temperature for one day and refrigerate cream and compote separately in covered bowls Assemble just before serving to keep everything crisp and beautiful For leftovers refrigerate covered for up to one more day though the pastry may soften

Ingredient Substitutions

Any juicy sweet blueberry works but wild Atlantic berries add the deepest flavor For the cream filling substitute vanilla extract if you cannot get vanilla bean and swap crème fraîche or Greek yogurt for mascarpone if needed Dairy free alternatives work for whipped cream as long as they are stable for piping

Serving Suggestions

This cake is at its best with just a few more fresh blueberries on top A little lemon zest is nice for serving during spring or to brighten the winter season For individual desserts pipe choux into small puffs and fill with cream and compote for a fun twist

Recipe FAQs

→ What makes pâte à choux pastry light and airy?

Pâte à choux is made by cooking flour into a dough with water, butter, and eggs. Steam created during baking causes the pastry to puff, resulting in a delicate, hollow texture perfect for layering or filling.

→ How do I achieve smooth vanilla bean cream?

Use chilled heavy cream and whip until soft peaks form. Gently fold in mascarpone for extra richness and smoothness. Scraping fresh vanilla bean seeds ensures flecks and true flavor.

→ Can frozen blueberries be used for the compote?

Yes, both fresh and frozen Atlantic blueberries work well. Frozen berries may release more juice; simply simmer slightly longer to thicken the compote as needed.

→ What’s the best way to assemble the layers?

Ensure the choux rounds are fully cooled. Spread cream evenly, then layer the blueberry compote before topping with the next choux round. Finish with more cream and fresh berries.

→ How do I store leftovers to maintain texture?

Keep the assembled cake covered in the refrigerator for up to one day. The choux may soften over time, so enjoy soon after assembling for the best texture contrast.

→ Is mascarpone cheese required in the cream?

Mascarpone adds extra richness and stability, but it’s optional. The cream will still be delicious without it; just ensure it’s whipped to a thick consistency.
