Ingredients

Zucchini oat bar ingredients in glass bowls.
  • Sprouted gluten free oats – 2 1/4 cups. Sprouted oats can be easier to digest for some people.
  • Banana – 1 ripe banana. The riper it is, the sweeter the bars.
  • Zucchini – 1 cup, grated and excess liquid squeezed out.
  • Chocolate chips – 1/2 cup. Use dairy-free chips if you need the bars to be dairy-free.
  • Maple syrup – 1/4 cup. Pure maple syrup provides the best flavor; honey can be used as a substitute.
  • Coconut milk – 3/4 cup (or unsweetened almond milk).
  • Cinnamon – 1/2 tsp for warmth and depth of flavor.
  • Egg – 1 large, to bind the mixture.

Substitutions and Variations

  • Add mild vegetables like grated cauliflower or thawed cauliflower rice for extra volume without changing flavor much.
  • Stir in seeds (flax or chia) or sliced almonds for extra nutrients and texture.

If you try other substitutions, note them and adjust cooking times as needed.

  • Tip #3: Let the bars cool completely (about 10 minutes) before cutting to help them hold together.

Recipe FAQ’s

How should I serve this?

Warm or room temperature are both great. Top with fresh berries or banana slices. Reheat in the microwave for 20 seconds or in a 350°F oven for 5–10 minutes.

Are oats Paleo?

Oats are generally not considered Paleo because they are a grain. Some people reintroduce them successfully once their gut health improves.

How can I tell the bars are cooked through?

They should look golden and slightly dry in the center. You can also insert a toothpick—if it comes out mostly clean, they’re done.
