Β Upside-down Rhubarb Brunch Cake has a buttermilk cake base and is topped with tangy rhubarb laced with gooey caramel, which makes this already-moist cake irresistible.

Whenever I think of upside-down cake, I think about the Pineapple Upside-down cake that was popular in the 80s, when I was a kid – a piece of cake topped with an unnaturally bright red maraschino cherry in the middle of a ring of too-sweet canned pineapple.

This is not your typical upside-down cake from the 80s. This Upside-down Rhubarb Brunch Cake is the real deal.

Rhubarb is overflowing from my local farmer’s markets and grocery stores and I’m taking full advantage this year! I’ve already made Strawberry Rhubarb Jam and Mini Banana Rhubarb Muffins – and now I’m baking it into a cake.

I don’t make cakes too often because I honestly don’t like cake all that much. (I know, the shock and horror of this admission from a food blogger!! I would much rather eat pie any day.)

But this is a cake I can get behind. Upside-down Rhubarb Brunch Cake has a buttermilk cake base and is topped with tangy rhubarb laced with gooey caramel, which makes this already-moist cake irresistible.

I would recommend baking this cake on the day you intend to serve it – as the days passes, the cake gets moister and moister – which isn’t necessarily a bad thing (we’ve still enjoyed it 3 days later!), but optimal texture is definitely on day 1.

Serve Upside-down Rhubarb Brunch Cake with a strong cup of tea, and if you really want to wow your brunch party guests, serve it with vanilla bean ice cream!
