Preparation

  • In a large mixing bowl, combine rolled oats, peanut butter, honey or maple syrup, lemon juice, lemon zest, and shredded coconut if using.
  • Mix until well combined and a sticky dough forms. Adjust consistency with more lemon juice or oats if necessary.

  • Place the cookies on a baking sheet lined with parchment paper.
  • Refrigerate for at least 30 minutes to firm up.

Notes

For best results, double the batch and store the cookies in an airtight container in the fridge for up to 5-6 days. Can be frozen for longer storage; just let them soften slightly before serving.
