Create bakery-style Boston Cream Pie Cookies at home. This recipe delivers soft vanilla cookies filled with rich homemade pastry cream and topped with a smooth chocolate ganache.

Ingredients

Scale
  • For the Soft Vanilla Cookies:
  • 1 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • For the Pastry Cream Filling:
  • 1 1/2 cups whole milk
  • 1/2 cup granulated sugar
  • 3 large egg yolks
  • 3 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • For the Chocolate Ganache Topping:
  • 4 ounces semi-sweet chocolate, chopped
  • 1/2 cup heavy cream
  • 1 tablespoon unsalted butter

Instructions

  1. Make the Cookie Dough: In a large bowl, cream the softened butter and sugar until light and fluffy. Beat in the egg and vanilla extract. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  2. Chill the Dough: Wrap the dough in plastic wrap and chill in the refrigerator for at least 1 hour. This step helps the cookies keep their shape.
  3. Bake the Cookies: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper. Roll the chilled dough into 1.5-inch balls and place them 2 inches apart on the prepared sheets. Flatten each ball slightly with the bottom of a glass. Bake for 10 to 12 minutes, or until the edges are lightly golden. Let the cookies cool completely on the baking sheets before moving them.
  4. Prepare the Pastry Cream: Heat the milk in a saucepan over medium heat until it just begins to simmer. While the milk heats, whisk the sugar, egg yolks, and cornstarch together in a medium bowl until pale yellow.
  5. Temper the Eggs: Slowly pour about half of the hot milk into the egg mixture while constantly whisking. Pour the tempered egg mixture back into the saucepan with the remaining milk.
  6. Cook the Cream: Cook over medium heat, whisking constantly, until the mixture thickens significantly and comes to a boil. Boil for 1 minute while continuing to whisk. Remove from heat and stir in the vanilla extract. Transfer the pastry cream to a clean bowl, press plastic wrap directly onto the surface to prevent a skin from forming, and chill for at least 2 hours until cold and firm.
  7. Make the Chocolate Ganache: Place the chopped chocolate in a heatproof bowl. Heat the heavy cream and butter in a small saucepan until simmering. Pour the hot cream mixture over the chocolate. Let it sit for 5 minutes, then whisk until smooth and glossy. Let the ganache cool slightly until it is thick enough to spread but still pourable.
  8. Assemble the Cookies: Once the cookies are cool and the pastry cream is firm, use a small offset spatula or piping bag fitted with a round tip to spread a generous layer of pastry cream onto the flat side of one cookie. Top with a second cookie to create a sandwich.
  9. Glaze: Dip the top of each assembled cookie into the chocolate ganache, or drizzle the ganache over the top. Let the chocolate set before serving.

Notes

  • For the softest cookie texture, avoid overmixing the dough once the flour is added.
  • If you want a quicker filling, you can use high-quality vanilla pudding mix prepared according to package directions instead of homemade pastry cream.
  • Chill the assembled, filled cookies for 15 minutes before dipping them in the ganache; this helps prevent the filling from squeezing out.
