Upside-Down Almond Rhubarb Cake


It’s time to celebrate the rhubarb season. The spring is here, and some of the fresh ingredients straight from the garden are already here. This years the spring for me means that another semester in the university will come to an end. It looks like my master’s degree studies are soon coming to an end. Some of you have asked me why do you even study law? The truth is that the most exciting part for me is copyright law (+ its combination with international law and the Internet). 🙂 Might sound strange, but that’s probably the reason why I even stayed in uni (+ I don’t like to leave things unfinished).

Anyway, enough university talk. Let’s celebrate the spring with the simple upside-down almond rhubarb cake. This cake here is the most basic gluten and refined sugar-free that you can enjoy on its own or serve it with ice cream. I must say that it’s hard to make a difference with this almond meal cake and plain flour cake. Almonds itself have enough fat inside, and you don’t even need to use butter to make it moist.
