The Boil: In a small saucepan, combine the coconut milk, maple syrup, and nut butter. Bring to a soft boil over medium heat. Let the mixture boil for exactly one minute, then remove from heat.
The Mix: Immediately stir in the lemon zest, vanilla, salt, and GF oats. Stir until the oats are completely coated and the mixture is well combined.
The Scoop: Using a cookie scoop, portion out 12 even balls onto a baking sheet lined with parchment paper. Use the bottom of a measuring cup to gently flatten each ball into a cookie shape.
The First Chill: Place the tray in the freezer for at least 10 minutes to set the base.
The Dip: While the cookies chill, melt the white chocolate chips and coconut oil together using a double boiler (or in 30-second increments in the microwave) until smooth.
The Finish: Using a fork, dip each chilled cookie into the white chocolate until coated. Return to the parchment paper and freeze for another 10 minutes to set the shell.
Store: Keep these in an airtight container in the fridge or freezer for the perfect chilled, zesty bite.
