Vienna Plum Cake : Low Carb : Gluten Free

British plums are in season from August to October, they are wonderfully versatile and can simply be eaten as they are or used in sweet late summer bakes. With a smooth, chalky skin and juicy flesh, this succulent British fruit is popular. They vary in colour from golden to purple, and popular varieties include Victoria and Marjorie Seedling.

So it is with plums in mind that I share this recipe for a low carb / Keto Vienna Plum Cake. It's a sweet and dense vanilla almond cake with tangy, juicy plums baked into the top, and yes, it's low carb and gluten free!

... and before the recipe a little more about the "Viennese plum cake." It is often referred to as Zwetschkenkuchen, and doesn't have a single, definitive origin story like the Sachertorte. It evolved from European traditions of using dried fruits and spices in festive cakes, and became associated with Vienna through its use of local plums, particularly the "Zwetschke" variety. While not a dish with a specific royal or historical origin, it's deeply rooted in Austrian culinary culture and is a popular treat, especially during plum season....

I like cake but I like fresh plums better. Our tree is very generous this year, with enough for the humans and the birds.

We seem to have more plums when I was young. I seldom have plums now. But I always was a fan of plum cake. Your recipe looks delicious.

Lovely recipe. Plums are a favorite fruit. Here in the USA, the crops at grocery store can be hit or miss, sweet or bitter and hard.

I love plums. I'm not a baker or hardly a cook anymore but I would definitely eat it if someone made it. I love plums. I use to have a plum tree before I moved to the mountains. The plums were amazing.

My son gave me a bag of mini plums from his garden last week.
