rhubarb banana cake + cashew icing // gf, vegan

rhubarb banana cake

I’ve had a very, very busy life lately. Studying my soul away, graduating from high school and completing my final exams hasn’t left a lot of time for baking, blogging and social media-ing. Now, finally, I have had a free weekend to bake – after working every saturday for the past few months. I also sort-of-didn’t-really quit my job. My boss desperately needed me to stay on so I set a few ‘demands’. Now I no longer work saturdays, and I no longer work with three colleagues who were exacerbating my depression, anxiety and general frustrations. 

I desperately wanted cake. I wanted it ASAP. On the kitchen bench were two overripe bananas that I forgot to freeze. There was rhubarb in the fridge – turning. Whilst gazing at the massive rhubarb plants spreading through my veggie patch (the leaves are larger than my torso. Seriously.) a lightbulb instantly appeared above my head, and then boom! Some rhubarb banana cake, cashew icing included, magically appeared out of nowhere after conjuring my fairy godmother.

Kidding. However, it did take less than an hour. 

An hour very well spent. Melting, mixing, folding, pouring, icing and then eating this cake made a little of my depression dissipate. There wasn’t even any guilt involved because I knew this was made from entirely natural ingredients that are better for me than all the regular refined ingredients, additives and preservatives dumped into packaged cakes. Also, it’s 6 inch, so that probably helped.

Licking the spoon helped too. Baking therapy for the win.

If you’re having a bit of a blue patch (sadness) or a grey patch (loneliness) or even a red patch (hangry) this rhubarb banana cake should soon sort you out. Especially if it’s a red patch. 

Much love, your author the bakery employee who quit but was then reemployed two days later, Rosie.
