Description
These cookies are everything you love about Boston cream pie in bite-size: tender, cake-like vanilla cookies sandwiched with rich custard and topped with smooth, silky chocolate ganache.
Ingredients
For the vanilla cookies:
-
½ cup unsalted butter, softened
-
¾ cup sugar
-
1 large egg
-
1 tsp vanilla extract
-
1 ½ cups all-purpose flour
-
1 ½ tsp baking powder
-
¼ tsp salt
-
¼ cup milk
For the custard filling:
-
1 cup milk
-
2 egg yolks
-
¼ cup sugar
-
1 tbsp cornstarch
-
1 tbsp butter
-
1 tsp vanilla extract
For the chocolate ganache:
-
½ cup semi-sweet chocolate chips
-
¼ cup heavy cream
Instructions
1️⃣ Make the custard: In a saucepan over medium heat, whisk milk, egg yolks, sugar, and cornstarch. Cook, stirring constantly, until thickened (about 5–7 minutes). Remove from heat, stir in butter and vanilla. Let cool completely, then chill.
2️⃣ Preheat oven: Set oven to 350°F (175°C). Line a baking sheet with parchment paper.
3️⃣ Make the cookie dough: Cream butter and sugar until fluffy. Beat in egg and vanilla. Mix in flour, baking powder, and salt. Stir in milk until smooth.
4️⃣ Bake cookies: Drop tablespoonfuls of dough onto baking sheet. Flatten slightly. Bake for 10–12 minutes until edges are lightly golden. Cool completely.
5️⃣ Make the ganache: Heat cream until just simmering. Pour over chocolate chips and let sit 1 minute. Stir until smooth and glossy.
6️⃣ Assemble: Spread or pipe chilled custard onto the flat side of one cookie, top with another. Spoon ganache over the top and let set.
Notes
-
