How To Make Gluten Free Zucchini Blondies

Add your wet ingredients to a bowl – zucchini, almond butter, maple syrup, eggs, vanilla, and whisk until smooth
Add dry ingredients and fold together
Add in most of your chocolate chips, reserving some for topping
Pour and spread into 8×8 baking dish lined with parchment paper, then top with remaining chocolate chips
Bake at 350 for 28-32 minutes, until top starts to golden

Storage and Reheating

Room Temperature:
Store blondies in an airtight container for 3 days. They stay soft and chewy thanks to the zucchini.

Refrigerator:
Keeps them fresh for up to 1 week. The texture becomes slightly firmer, which is great for clean slicing.

Freezer:
Freeze individually wrapped blondie squares for up to 3 months. Thaw at room temperature or warm briefly.

Reheating for Gooey Chocolate:
Warm a blondie square in the microwave for 8–10 seconds for that perfect melty chocolate pull.

FAQ

Can I use almond flour instead of oat flour?

Yes — but almond flour creates a softer, more tender blondie. Oat flour gives the best chewy structure.

Do these taste like zucchini?

Not at all. Once squeezed and baked, zucchini adds moisture but no detectable flavor.

Can I make these dairy‑free?

Absolutely — just use dairy‑free chocolate chips.

Can I add protein powder?

Yes. Replace the almond flour with ¼ cup vanilla protein powder for a macro‑friendly version.

How do I prevent gummy blondies?

Make sure your zucchini is squeezed very dry and use the full amount of oat flour (¾ cup).
