01 - Line a large baking sheet with parchment paper or a silicone baking mat to prevent sticking.
02 - In a large bowl, combine Rice Krispies cereal, mini marshmallows, and chopped pecans. Mix thoroughly and set aside.
03 - In a medium saucepan over medium heat, melt butter. Add brown sugar, brewed coffee, espresso powder, and salt. Stir constantly until smooth and just beginning to bubble, approximately 2-3 minutes. Remove from heat and stir in vanilla extract.
04 - Pour the hot coffee mixture over the cereal mixture. Using a spatula, quickly fold and stir until all ingredients are evenly coated with the coffee mixture.
05 - Using a cookie scoop or tablespoon, drop mounds of the mixture onto the prepared baking sheet. Press gently with the back of the spoon to form rounded cookie shapes if needed.
06 - Melt chocolate chips with coconut oil in a microwave-safe bowl, heating in 20-second intervals and stirring between each until smooth. Drizzle melted chocolate over the shaped cookies.
07 - Transfer the baking sheet to the refrigerator and chill for at least 30 minutes, or until cookies are firm and set.
08 - Store cookies in an airtight container in the refrigerator for up to 1 week to maintain freshness and texture.
