One of the best indicators that spring is finally here to stay is when my rhubarb plant finally pops above the ground. It is incredibly faithful; no matter how cold the winter was, it never fails to grow again each May. Right now it is out-of-control, as the towering green leaves threaten to take over my entire garden. I’ve been looking for new ways to cook and bake with it, and was intrigued by rhubarb upside-down cake I spotted on Pinterest. However, I had a bucket of brioche in my fridge, so instead of mixing up cake batter I simply rolled out my dough and placed it over hot rhubarb and sugar. It was a success: a sweet-tart treat perfect for breakfast, or afternoon snacking.
