This is a wonderful recipe for an autumnly plum sheet cake. It’s an easy recipe and the perfect cake for a crowd. It’s gluten free, made with basmati rice and ground almonds and sugar reduced. This cake is ideal for an afternoon snack cake or a Sunday dessert for you and your family.
Fall is almost at our door steps. The air already holds the promise of colder weather and the leaves start to change their colouring from hues of green to more vibrant colours. I truly love this season. Especially when I’m fed up with the hot temperatures and the sweaty and sticky nights because the house holds about 1000° degrees Celsius 😉 . My kids are cranky too when the nights are as hot as the days. Without air-condition its almost unbearable. That’s why we are all so happy and welcoming fall with everything we have . That leads us directly to this beautiful recipe for an Autumnly Plum Sheet Cake!

1000 and 1 autumnally plum sheet cakes!
I love developing new recipes and exploring new flavours. Most of the time it’s a very rewarding job but it also holds it’s challenges especially when you aren’t 100% satisfied with the outcome but your family begs you on their knees to just stop baking the same cake over and over again. I can’t help myself I have to redo it over and over again until I feel satisfied with what I baked or cooked up. I know sometimes I can be a real tyrant but believe me I just do it for the greater good of baking and enjoying food ;-).

Why do I use Basmati Rice for most of my gluten free baked goods.
I know many people of you have problems with their gut and are sensible to gluten or if nothing else just try to develop a healthier lifestyle for themselves and their families. It’s the same for me. I always had a sensitiv gut and can’t eat everything I like on a daily base. I started thinking about what alternatives there are for white flour. As you may noticed most of our recipes are without white bleached flour and are mostly naturally sweetened and or sugar reduced.
Healthier recipes!
We like to enjoy sweet things but at the same time we like to make our food healthier and more enjoyable for us. That’s why we most of the time use spelled flour, sweet potatoes or ground basmati rice instead of white flour. And it’s the same for this sheet cake with ripe plums .
To buy organic rice is very important for me. It is very important to ground the rice almost as fine as flour.
Rice is a stable in every household.
Rice in general is a stable in almost every house and it’s the same for me that’s why I like to use it for baking. It’s one thing I will always have at home. The difference is that my choice of rice is always basmati. I love the taste and I always buy organic which is very important for my baked goods. Organic tells me that it’s hopefully free from pollution coming through air, pest control, water and other factors.
Basmati is a very slim corn and it’s easy to ground it at home in your blender to flour. It has almost the same behaviour when used for baking as normal flour. It’s just very important to ground it very very fine.

Let’s start baking and just stop talking about anything other than the plum sheet cake, will you please Nina?!?

The important things first!
- The basmati rice needs to be grounded in your blender as fine as possible. That’s important because if the ground rice is to course the batter needs more liquid and has to stay longer in the oven.
- All ingredients need to be at room temperature, if some of the ingredients are to cold you don’t get a homogenous batter and that is important for the success of every baking recipe. So please take all the chilled fresh ingredients out of the fridge 20 minutes before you start baking.
- Measure everything accurately .
- The butter and the sugar must be whisked until light pale and fluffy. That will be about 10 minutes.
- The egg whites need to be beaten until very stiff. Please fold them in gently into the dough.
- Don’t count on your oven to be exactly like mine. Please have an eye on your cake . That means always put a wooden skewer into the cake to make sure that it is done .

Autumnly plum sheet cake.
- Start with preheating the oven. That’s always a good first step 😉
- Prepare the baking sheet with baking paper.
- In a medium bowl mix together all dry ingredients.
- In another medium bowl mix together the milk, greek yoghurt (or as I prefer skyr yoghurt), vinegar and vanilla extract.
- Separate the eggs and beat the egg whites until very stiff.
- In a bowl of stand mixer start creaming the room soft butter cubes with the brown sugar until pale and fluffy. About 10 minutes.
Half of the work is already done.
- Add the egg yolks one at the time to the butter mixture and mix until just incorporated.
- Ad in 5 steps alternately the wet and the dry ingredients starting and ending with the dry ingredients. Mix until slightly incorporated.
- Now gently fold in the stiff egg whites with a spatula. Don’t overdue it. We want all the air in the batter.
- Pour the batter onto the prepared baking sheet and put the plum halves with the cut side up gently on top of the cake batter. Arrange the plums next to each other in neat rows.
- Sprinkle the sugar-cinnamon mixture on top of the cake.
- Put the cake into the oven and bake for about 35 minutes or until a wooden skewer comes out clean.
- Let the cake cool down and cut it into 10x10cm squares.
Gently fold in the stiff beaten egg whites We want to keep the air in our batter!

Enjoy the cake as it is or with some powdered sugar or if your are extremely brave ;-), add some beaten and slightly sweetened cream on top.
