BOSTON CREAM PIE COOKIES

Category: Cookies

For the custard:
1 cup milk
6 tbsp whipping cream
6 tbsp sugar
3 tbsp cornstarch
1/4 tsp salt
1 large egg yolk
2 tsp vanilla extract

For the cookies:
1 cup flour
1 cup plus 2 tbsp cake flour
3/4 tsp baking soda
1/2 tsp salt
9 tbsp unsalted butter at room temperature
1 cup plus 1 tbsp sugar
2 tsp vanilla extract
1/2 tsp grated lemon zest
2 large egg yolks at room temperature
1 whole egg at room temperature
1/2 cup plus 2 tbsp buttermilk at room temperature

For the chocolate glaze:
1/2 cup whipping cream
2 oz. unsweetened chocolate, chopped
1 tbsp plus 1 tsp unsalted butter at room temperature
6 tbsp confectioners sugar

To make the custard, place 1/2 cup plus 2 tbsp of the milk, the cream, and the sugar in a medium saucepan over medium heat. Bring just to a boil. Dissolve the cornstarch and salt in the remaining milk in a small bowl. Whisk in the egg yolk and then whisk into the hot-cream mixture. Whisk over medium-low heat until thick, about 2 to 3 minutes. Remove from the heat and stir in the vanilla. Transfer to a bowl, cover the surface with plastic wrap, and refrigerate for 2 to 3 hours.

To make the cookies, preheat the oven to 400. Lightly spray several baking sheets with nonstick cooking spray.

Whisk together the flours, baking soda, and salt in a small bowl.

In a medium bowl, beat the butter, sugar, vanilla, and lemon zest until light and fluffy, about 2 minutes. Beat in the egg yolks and then the whole egg, followed by the buttermilk. Fold in the flour mixture and stir until smooth. Drop by generous tbsp about 2 inches apart on the prepared sheets. Bake for 10 to 11 minutes, or until the cookies are firm yet spongy to the touch. Let cool. Turn a cooled cookie upside down and spread with a rounded tbsp of cooled custard. Top with a cookie. Continue in this manner until there are no more cookies.

To make the chocolate glaze, scald the cream in a small saucepan. Transfer to a small bowl and add the chocolate and butter. Whisk until smooth. Add the confectioners sugar and stir until velvety. Spread a scant tbsp of chocolate evenly across the top of each custard-filled cookie. Serve at room temperature. Makes 13 cream-filled cookies.
