Notes
Store cooled cookies in an airtight container at room temperature for up to 1 week or in an airtight container for up to 2 weeks.
Freeze in a freezer-safe bag or container for up to 3 months.
For nut-free version swap peanut butter for sunflower seed butter or tahini and use pumpkin or sunflower seeds instead of walnuts.
Use very ripe banana for the sweetest, creamiest texture.
Don’t overbake—the cookies will firm up as they cool.
Wet your hands when shaping the cookies to avoid sticking.
Use parchment paper to prevent sticking and make cleanup easier.
Measure the grated apple in cups loosely, without pressing or squeezing
Measure ingredients accurately as written to avoid making the batter too wet or dry.
