How do you feel about this recipe? I’m pretty psyched because I have 712 zucchini growing in my garden, so I need a delicious go-to recipe to use ’em up. Well, if you’re in a similar situation, things just got real. Because this right here is the world’s greatest No. 1 most amazing zucchini bread. Cinnamon Crunch Zucchini Banana Bread - And it’s also banana bread, and the world’s greatest of that, too. It’s tender, soft, fluffy and so super tasty, you guys.

And I’ll be honest, I was a bit leery making this bread with oat and almond flours. Things just get weird sometimes with substitutions, but I tell you what — subbing in those flours was one of the best decisions of my life. Okay, maybe that’s a bit dramatic, but you know.

And what’s super extra cool is the crispy, crunchy flaky topping that’s cinnamon and sugar. Hence the “cinnamon crunch” name. It just takes a little dusting, and voila! Life is all that. You’re in for a treat, friends.

Also, if you’re wondering, yes, I totally ate several bites of bread straight out of the pan. It was hot out of the oven, and I couldn’t wait to cut it so I just got a fork out and went for it.

Now is not the time for judgment. It’s just time to eat.
