📝 Ingredients

  • 1 3/4 cups old-fashioned oats or quick-cooking oats
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon fine sea salt (scale back slightly if using table salt)
  • 2 cups mix-ins* (nuts, seeds, chocolate, shredded coconut, or dried fruit)
  • 1 cup creamy peanut butter or almond butter

✨ Kitchen Tools You’ll Need

This recipe doesn’t require fancy gadgets, just a few reliable kitchen basics to keep everything simple and stress-free.

  • 9-inch square baking pan
  • Parchment paper
  • Mixing bowls
  • Food processor or blender (optional for chopping mix-ins)
  • Measuring cups & spoons
  • Spoon or spatula
  • Flat-bottomed glass for pressing

Step-by-Step Beginner-Friendly Instructions

  1. Line a 9-inch square baking pan with parchment paper, criss-crossing two strips for easy removal later.
  2. Add oats, cinnamon, and sea salt to a large bowl and stir to combine.
  3. Briefly blitz your mix-ins in a food processor. Add large nuts first for a few seconds, then add the remaining items and pulse until everything is broken into small, even pieces. Pour into the bowl with the oats.
  4. In a liquid measuring cup, combine nut butter, honey or maple syrup, and vanilla extract. Stir until smooth. If needed, warm the mixture slightly, but ensure it cools to room temperature before adding (especially if using chocolate mix-ins).
  5. Pour the wet mixture over the dry ingredients. Stir with a large spoon until everything is fully combined and no dry oats remain. If the mixture feels too loose or easy to stir, sprinkle in more oats until thick and firm.
  6. Transfer the mixture to the prepared pan. Spread evenly, then use the bottom of a flat glass to press it down as firmly as possible—this ensures the bars hold together.
  7. Cover and refrigerate for at least 1 hour, or overnight.
  8. Lift the set mixture from the pan using the parchment, place on a cutting board, and slice into 16 bars.
  9. Wrap bars individually in parchment or store in a single layer to prevent sticking.
