Ingredients

For the Sugar Cookies

2 ½ cups all-purpose flour
1 tsp baking powder
½ tsp salt
¾ cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
1 ½ tsp vanilla extract
2 tbsp milk

For the Vanilla Pastry Cream Filling

2 cups whole milk
½ cup granulated sugar
3 large egg yolks
3 tbsp cornstarch
1 tbsp unsalted butter
1 tsp vanilla extract

For the Chocolate Ganache Topping

1 cup semi-sweet chocolate chips
½ cup heavy cream

Instructions

Step 1: Prepare the Sugar Cookie Dough

Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking powder, and salt.
In a large bowl, cream butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in vanilla extract and milk.
Gradually add dry ingredients until a soft dough forms.
Scoop tablespoon-sized portions onto baking sheets, spacing 2 inches apart.
Slightly flatten each cookie.
Bake 10–12 minutes until edges are lightly golden.
Cool completely on wire racks.

Step 2: Make the Vanilla Pastry Cream

In a saucepan, heat milk over medium heat until steaming but not boiling.
In a separate bowl, whisk egg yolks, sugar, and cornstarch until smooth.
Slowly pour warm milk into the egg mixture while whisking continuously.
Return mixture to saucepan and cook over medium heat, stirring constantly until thickened.
Remove from heat and stir in butter and vanilla extract.
Transfer to a bowl, cover with plastic wrap touching the surface, and chill for at least 2 hours.

Step 3: Prepare the Chocolate Ganache

Heat heavy cream until just simmering.
Pour over chocolate chips in a bowl.
Let sit 2 minutes, then stir until smooth and glossy.
Allow ganache to cool slightly but remain pourable.

Step 4: Assemble the Cookies

Pipe or spoon vanilla pastry cream onto the flat side of one cookie.
Place another cookie on top to form a sandwich.
Spoon or drizzle chocolate ganache over the top cookie.
Allow ganache to set before serving.

Tips for Perfect Vanilla Custard Filled Cookies

Use Room Temperature Ingredients

This ensures smooth mixing and even baking.

Chill the Custard Completely

Warm custard will cause cookies to slide apart.

Don’t Overbake

The cookies should remain soft, not crisp.

Let Ganache Thicken Slightly

Too hot, and it will drip excessively.

Flavor Variations

Chocolate Cookie Base

Replace ¼ cup flour with cocoa powder for a chocolate twist.

Espresso Infused Ganache

Add ½ tsp espresso powder to the warm cream.

Mini Version

Use smaller cookie scoops for bite-sized treats.

White Chocolate Topping

Substitute semi-sweet chocolate with white chocolate for a sweeter finish.

Serving Suggestions

Boston Cream Pie Cookies are perfect for:

Birthday parties
Holiday dessert trays
Afternoon tea
Bridal showers
Potluck gatherings

Serve chilled or slightly room temperature for best texture. Pair with coffee, cappuccino, or cold milk.

Storage and Make-Ahead Instructions

Store assembled cookies in the refrigerator up to 3 days.
Keep in airtight container.
Freeze unfilled cookies up to 2 months.
Fill and top with ganache the day of serving for freshest texture.

Frequently Asked Questions

Can I use instant pudding instead of homemade custard?

Yes, but homemade pastry cream provides richer flavor and better texture.

Can I make them ahead?

Yes. Prepare components in advance and assemble before serving.

Why is my custard lumpy?

It may have cooked too quickly. Whisk constantly and strain if needed.

Why These Bakery Style Sandwich Cookies Stand Out

These Boston cream pie cookies capture everything people love about the classic dessert but offer better portability and portion control. The contrast between soft cookie, creamy custard, and glossy chocolate makes them visually appealing and irresistible.

They’re elegant enough for formal occasions yet simple enough for weekend baking.
