Ingredients
Method
Step 1: Make the Pastry Cream
- In a saucepan, whisk egg yolks, sugar, and cornstarch until smooth.
- Heat milk until just simmering and slowly pour into yolk mixture while whisking.
- Return to heat and stir constantly until thickened.
- Remove from heat, stir in butter and vanilla, then chill for 30 minutes.
Step 2: Prepare the Cookie Dough
- Cream butter and sugars until fluffy.
- Beat in egg and vanilla.
- Add flour, baking soda, and salt; mix until dough forms.
- Scoop dough onto a baking sheet and flatten slightly.
Step 3: Bake the Cookies
- Preheat oven to 180°C (350°F).
- Bake cookies for 10–12 minutes or until edges are golden.
- Cool completely before assembling.
Step 4: Make the Ganache
- Heat cream and pour over chocolate chips.
- Let sit for 1 minute, then stir until smooth and glossy.
Step 5: Assemble
- Pipe or spoon chilled pastry cream onto the flat side of half the cookies.
- Top with remaining cookies to make sandwiches.
- Drizzle or spread ganache on top. Chill to set.
Notes
- Cookies can be made ahead and filled later.
- For a shortcut, use store-bought vanilla pudding.
- Add a touch of espresso powder to the ganache for depth.
