Directions

  1. Line the pan

    Line an 8-inch square pan with parchment.

  2. Warm the binder

    Microwave peanut butter and honey for 30 to 45 seconds until fluid. Stir in vanilla and salt.

  3. Mix

    Fold in oats and flax until evenly coated. Press very firmly into the pan.

  4. Top

    Melt chocolate chips with coconut oil. Spread a thin layer over the bars and sprinkle with flaky salt.

  5. Chill

    Refrigerate 1 hour, then lift out and cut into 12 bars.

Swaps & notes

Easy swaps

  • Use almond or sunflower seed butter.
  • Replace flax with finely chopped nuts.
  • Add dried cherries or mini chocolate chips to the oat mixture.

Cook notes

  • Natural peanut butter can work but may produce softer bars; stir it thoroughly first.
  • Use quick oats for a softer texture, not instant oatmeal packets.

Storage

Refrigerate up to 10 days or freeze up to 2 months. They soften at warm room temperature.

Questions

Are these gluten-free?

They are when made with certified gluten-free oats.

Can I reduce the honey?

A little, but the bars rely on it for binding. Reduce by no more than 2 tablespoons.

Why are they crumbling?

The mixture was not packed firmly enough or the nut butter was unusually dry.
