1. Pour Kahlúa® into Shot Glass to about 1/2 full. 2. Using a spoon(inverted), slowly pour in the Peppermint Schnapps until glass is about 3/4 full. Done correctly, the Schnapps will flow under the Kahlúa® for a clear layer. 3. Again using a spoon, but this time right side up, slowly top off the glass with a layer of Baileys. Be careful to place the spoon right at the top of the Kahlúa® layer and to raise it as the glass fills up. Done correctly, this will provide a layer of Baileys floating over the Kahlúa® . 4. Toss it down all at once for something like a Peppermint Pattie, WITH A BANG!!! NOTE: Best if all ingredients are chilled
