Boston Cream Pie Cookies are soft sandwich-style cookies filled with creamy vanilla custard and topped with glossy chocolate ganache, offering a delightful twist on the classic dessert.

Ingredients

Units Scale
  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • For the custard:
  • 1 1/2 cups whole milk
  • 2 egg yolks
  • 1/4 cup granulated sugar
  • 2 tbsp cornstarch
  • 1/4 tsp salt
  • 1 tsp vanilla extract
  • For the ganache:
  • 1/2 cup heavy cream
  • 1/2 cup semi-sweet or dark chocolate chips

Instructions

  1. Whisk flour, baking powder, and salt in a bowl. In a separate bowl, cream butter and sugar until fluffy. Add eggs and vanilla, then mix in the dry ingredients. Chill dough for 30 minutes.
  2. Preheat oven to 350°F (175°C). Scoop dough onto a parchment-lined baking sheet and bake for 10–12 minutes until edges are lightly golden. Cool completely.
  3. For the custard: Heat milk in a saucepan until steaming. In a bowl, whisk egg yolks, sugar, cornstarch, and salt. Gradually add hot milk, whisking constantly. Return mixture to pan and cook until thickened. Stir in vanilla and chill.
  4. For the ganache: Heat cream until just simmering. Pour over chocolate chips and let sit for 1–2 minutes. Stir until smooth.
  5. Assemble cookies by spreading custard on the flat side of one cookie, topping with another, and spooning ganache over the top. Let set before serving.

Notes

  • Chill custard fully before assembling to avoid runny filling.
  • Use high-quality chocolate for best ganache results.
  • For even cookie size, use a scoop or weigh dough portions.
  • Cookies can be made smaller for bite-sized treats.
  • Assemble just before serving to maintain texture.
