Special thank you to Amore di Mona for sponsoring this post.
My Easter special Rosemary Lemon Brownies are probably the healthiest baked brownies you will find. With an original rosemary lemon flavour, dark chocolate, hidden zucchini and grain-free cassava and tigernut flour these make a fabulous wholesome yet indulgent treat.
I am continuing to experiment with grain-free flours and cassava and tigernut are quickly becoming one of my favourites to bake with and worked really well in this recipe. As you can see I have also used zucchini that is completely disguised in the brownies and ads extra fudginess.
Brownies are normally loaded with sugar and I really tried to use the least sugar possible without affecting the final result. I’ve used rapadura, you can use any of your favourite raw sugar.
The flavours I’ve used are different to what you would normally expect in brownies. Lemon is often paired with white chocolate but it’s rather interesting with dark chocolate too. Definitely worth to try if you never have. In my opinion rosemary and dark chocolate are fabulous combo and if you love this herb as much as me you are in for a treat.
However the flavours are open for your own adaptation and you could put your own spin on the recipe or try it without the lemon zest to see what you prefer.
As you would expect from brownies they are fudgy and moreish. I have used 120g of dark vegan chocolate in the recipe and you could add even little more if you like. To make them extra special I have decorated them with some whipped oat cream mixed with little cacao powder and topped them with rosemary sprigs, lemon slices, lemon zest and shaved chocolate.
Hope you love them :)

Hola Hana! En Argentina es dificil encontrar chufa o harina de chufa, pero ya las encargue, quiero probar este brownie, no me lo pierdo por nada del mundo. Gracias! Un cariño enorme!!!
Hola Marcela! Ah, you’re so beautiful! Hope you love them! Lots of love :)
Dear Hana,
this looks like a wonderful recipe, and I’d love to try it.
As I do nto have all the ingredients on hand, I was wondering how I could substitute. Do you think almond flour could work instead of cassava flour? I do not have regular tigernut flour, but could use either some raw tigernut flakes or roasted tigernut flour. And would using coconut sugar make a significant difference in taste?
Many thanks for your help. I am still new to this kind of baking..
