Ingredients
  

Essentials

  • 1 cup rolled oats Old-fashioned oats give the best chew.
  • 1/2 cup peanut butter or almond butter Use smooth or slightly chunky.
  • 1/4 cup honey or maple syrup Sweetener to bind and balance the lemon.
  • 1/4 cup lemon juice Fresh is best for bright flavor.
  • Zest of 1 lemon Adds concentrated lemon aroma.
  • 1/2 teaspoon vanilla extract
  • A pinch of salt

Optional Add-ons

  • 1–2 tablespoons chia seeds or ground flaxseed For a fiber boost.
  • 1/4 cup shredded coconut For texture and mild sweetness.
  • 2 tablespoons mini chocolate chips Stir in after mixing so they don’t melt.
  • 1–2 tablespoons poppy seeds For extra lemon pairing.
  • 1 tablespoon Greek yogurt Thick to make them a bit softer.
  • A sprinkle of powdered sugar mixed with lemon zest For a light dusting if serving to guests.

  • Add wet ingredients: Add the peanut or almond butter, honey or maple syrup, lemon juice, lemon zest, vanilla, and a pinch of salt to the oats.
  • Mix until combined: Stir until the mixture is evenly moistened.
  • Form cookies quickly: Use a tablespoon or small cookie scoop to portion the dough and shape into cookies.
