Ingredients
Method
Preparation
- Preheat the oven and line a baking sheet with parchment paper.
- Whisk flour, cocoa powder, baking soda, and salt in a bowl.
Mixing
- Beat butter and sugar until light and slightly fluffy.
- Beat in the egg, vanilla, buttermilk, and red food coloring until smooth.
Combining
- Gradually add the dry mix to the wet mix and stir until just incorporated.
- Gently fold in the crushed sandwich cookies.
Baking
- Scoop tablespoon-sized portions onto the sheet and bake for 10–12 minutes until edges set.
- Cool a few minutes, then transfer to a rack to cool completely.
Notes
Use room temperature butter for easier creaming and measure flour correctly to prevent dense cookies. Chill the dough if it is warm and watch the bake time to keep centers soft.
