Baking Instructions
- Step 1: Preheat Your Oven. Begin by preheating your oven to 350°F (175°C). This ensures that your cookies bake evenly.
- Step 2: Prepare the Cookie Dough. In a large mixing bowl, cream together the room temperature butter and sugar until light and fluffy. This should take about 2-3 minutes. Add in the milk, egg, and vanilla extract, mixing until well combined.
- Step 3: Combine Dry Ingredients. In a separate bowl, whisk together the flour, cocoa powder, salt, and baking soda. Gradually add this dry mixture to the wet ingredients, stirring until just combined. Be careful not to over-mix, as this can lead to tough cookies.
- Step 4: Scoop the Dough. Using a cookie scoop or tablespoon, portion out the cookie dough onto a parchment-lined baking sheet. Leave enough space between each scoop to allow for spreading.
- Step 5: Bake the Cookies. Bake the cookies in the preheated oven for 10-12 minutes, or until they are set around the edges but still soft in the center. Remember, they will continue to cook slightly after being removed from the oven.
- Step 6: Prepare the Marshmallow Filling. While the cookies are baking, prepare the marshmallow filling. In a mixing bowl, combine the softened butter, cocoa powder, milk, confectioners' sugar, and vanilla extract. Mix until smooth and fluffy.
- Step 7: Assemble the Cookies. Once the cookies are out of the oven and slightly cooled, take a cookie and spread a generous amount of the marshmallow filling on the bottom side. Top with another cookie, pressing gently to create a sandwich. Repeat until all cookies are filled.
Notes
- Store cookies in an airtight container at room temperature for up to 5 days.
- If you want to keep them for longer, consider freezing them.
- Thaw frozen cookies at room temperature before enjoying.
