👩‍🍳 How to Make Zucchini Snack Bars (Step-by-Step)

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.

Step 2: Grate the Zucchini

Grate your zucchini using the fine side of a box grater. Wrap it in a clean towel or paper towels and squeeze out as much moisture as possible—this keeps the bars from getting too wet.

Step 3: Combine Dry Ingredients

In a large mixing bowl, whisk together:

• Oats

• Flour

• Baking powder

• Baking soda

• Cinnamon

• Nutmeg (if using)

• Salt

Step 4: Mix Wet Ingredients

In a separate bowl, whisk:

• Egg

• Mashed banana (or applesauce)

• Maple syrup or honey

• Oil

• Vanilla extract

Stir in the grated zucchini until well combined.

Step 5: Combine Wet & Dry

Add the wet mixture to the dry ingredients and stir gently with a spatula until just combined. Fold in any optional add-ins like chocolate chips or raisins.

Step 6: Bake

Pour the batter into the prepared baking pan and smooth the top. Bake for 25–30 minutes, or until the center is set and a toothpick comes out clean.

Let cool in the pan for 10 minutes, then lift out using parchment and let cool fully on a wire rack before slicing into bars.

❓ FAQ: Zucchini Snack Bars
