Method:
- In a large mixing bowl, combine 1/2 cup of unsalted butter and 1/2 cup of granulated sugar with 1/2 cup of packed dark brown sugar. Using an electric mixer, beat them together until light and fluffy, about 2-3 minutes.
- Add 1 large egg and 1 teaspoon of vanilla extract to the mixture. Beat until well combined.
- In a separate bowl, whisk together 1/2 cup of all-purpose flour, 1/4 cup of cocoa powder, 1 teaspoon of baking soda, 1/2 teaspoon of salt, and 1 teaspoon of instant espresso powder (if using).
- Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Fold in 1 cup of rolled oats with a spatula.
- Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper. Using a cookie scoop, place heaping tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 10-12 minutes.
- While the cookies are cooling, prepare the vanilla bean buttercream. Beat 1/2 cup of unsalted butter until creamy. Add the scraped seeds from 1 vanilla bean, 1 cup of powdered sugar, 2 teaspoons of whipping cream, and a pinch of salt. Beat until fluffy and smooth.
- Once the cookies are cooled, flip half of them upside down. Spread a generous amount of buttercream on the flat side of each cookie. Top with another cookie.
