- Stir in the chocolate chips.
Bake the Cookies

- Bake in a preheated oven at 350°F (175°C) for 10-12 minutes.
Buttercream Filling (Option 1)
- In a clean bowl, beat together softened butter and powdered sugar until light and fluffy.
- Add vanilla extract, adjusting with a tablespoon of milk if the mixture is too thick.
Chocolate Ganache Filling (Option 2)
- Heat the heavy cream in a saucepan until just simmering, then pour over the chocolate chips in a bowl.
- Let sit for a few minutes, then stir until glossy and combined.
Assemble the Cookie Sandwiches
- Match up cookies of similar sizes.
- Spread a generous amount of filling between two cookies, then press gently together.
