    These Chocolate Zucchini Bread Brownies you guys, I die. They are unreal. 

    I am a sucker for all things chocolate, brownies and zucchini to be honest. I love zucchinis made into zoodles, in my smoothies and in many of my desserts as well.

    These brownies are super fudgey, delicious and they satisfy your sweet tooth craving without spiking the blood sugar like crazy. Plus they even have some Vital Proteins Collagen Peptides in it. My secret baking weapon 😉 I love adding collagen peptides to my recipes because you don’t even taste it and it has made such a difference in my own personal health.

    The number one product I always recommend investing in as a consumer are collagen peptides. It can be very overwhelming to see all the new products and supplements posted about on Instagram or that you read about online. You never really know what is worth spending money on and what can you can pass on.

    To be honest, everyone’s body is so different in what will make a difference. But for me personally and those around me, we have seen amazing results from using Vital Proteins. My hair, skin and nails have been stronger. It adds protein to my hot tea (yup, I always add to my hot tea) and really helps with my digestion. It is something I use each and everyday since it is so easy to sneak into anything!

    I can promise if you make these Zucchini Bread Brownies, you won’t even know they are in there.

    These Chocolate Zucchini Bread Brownies require just one bowl and a few ingredients. Plus they are egg-free and gluten free-friendly! I hope you guys love them as much as I do!

    Will they still come out yummy if I sub the oat flour for almond flour or coconut flour?

    • Reply Rachel June 16, 2018 at 6:31 pm

      i haven’t tested. definitely not coconut flour as it is very different. maybe almond flour but you may need to add a few more tablespoons

      hi denisse, this is a dessert 🙂 zucchini bread brownies have been quite the hit. i recommend trying them and youll be surprised how you don’t taste it. if this isn’t your thing, just omit it and add more chocolate chips. xx

    Is there a way to sub for the liquid coconut oil? Can I just melt coconut oil or grass-fed butter?
