Ingredients

You only need ten simple ingredients, many of which you likely already have in your pantry.

  1. Rolled oats (or store‑bought oat flour)
  2. Bananas
  3. Coconut oil
  4. Vanilla extract
  5. Milk or a non‑dairy alternative
  6. Chia seeds
  7. Baking powder
  8. Cinnamon
  9. Zucchini
  10. Dark chocolate chips (optional)

Make your own oat flour

Oat flour is easy to make at home: pulse rolled oats in a food processor or high‑speed blender until fine and flour‑like. Use a 1:1 ratio — 1.5 cups rolled oats yields about 1.5 cups oat flour. Store extra oat flour in an airtight container for future baking.

How to make the bars

The recipe is straightforward. The only slightly time‑consuming step is shredding and draining the zucchini. Use a box grater or food processor to shred, then press the zucchini in a clean dish towel or cheesecloth over the sink to remove excess moisture. Removing extra water prevents soggy bars.

Combine wet ingredients, mix in dry ingredients, fold in drained zucchini and chocolate chips, and bake in an 8×8 pan. In about 27 minutes you’ll have golden, flavorful bars that cool and slice beautifully.

Kitchen tools

  • Grater or food processor for shredding zucchini
  • Mixing bowl and spoon
  • 8×8 baking dish
  • Parchment paper (optional, for easy removal)
