Equipment

  • Microwave-safe bowl
  • Whisk
  • Mixing spoon or spatula
  • Cookie scoop
  • Parchment paper
  • Baking sheet

Ingredients
  

  • 1 cup 164 g white chocolate chips
  • 2 tbsp 30 ml fresh lemon juice
  • 2 tsp lemon zest
  • ½ cup + 2 tbsp 57 g quick oats

Instructions
 

  • Line a baking sheet with parchment paper.
  • Melt white chocolate chips in a microwave-safe bowl, 15–30 seconds at a time, stirring in between, until smooth.
  • Whisk in the lemon juice until smooth and creamy.
  • Stir in lemon zest and oats until evenly mixed. Batter will be thick!
  • Scoop 1 tbsp-sized portions onto the tray and flatten slightly into disks using the back of a spoon or your fingers.
  • Optional: sprinkle a little extra zest on top for extra flavor and brightness.
  • Chill in the fridge for 30–60 minutes, or until cookies are firm to the touch. Let sit at room temperature for 10–15 minutes before eating.

Notes

  • You’ll only need one large lemon for both juice and zest — maybe not even the whole thing!
  • Be sure to strain your lemon juice for best texture.
  • Want them sweeter? Use 2 tbsp less oats.
  • Want more oat flavor? Add 2 tbsp more oats.
  • Smaller scoops work great — I use a 1 tbsp OXO scoop.*
  • Store in an airtight container in the fridge for up to 1 week, or freeze for longer.
