Ingredients

Scale
  • ½ cup unsalted butter

  • 2 tablespoons fresh lemon juice

  • ½ teaspoon salt
  • ½ cup white chocolate chips (optional)

  5. Add quick oats and salt, stirring until well combined.
  6. If using, fold in white chocolate chips while the mixture is still warm.

  8. Let the cookies cool at room temperature for about 30 minutes or until set.

Notes

  • Use fresh lemon juice and zest for the best flavor—bottled juice won’t give the same bright citrusy taste.
  • Quick oats work best, but if using old-fashioned oats, pulse them in a blender a few times for a softer texture.
  • For a firmer texture, refrigerate the cookies for at least 30 minutes before serving.
  • Store in an airtight container at room temperature for up to 1 week, in the fridge for 2 weeks, or freeze for up to 3 months.
  • Want a healthier version? Swap granulated sugar for honey or maple syrup and use coconut oil instead of butter.

These easy, no-bake lemon oatmeal cookies are a delightfully chewy and refreshing treat—perfect for lemon lovers and no-bake dessert fans alike! 🍋✨
