I love rhubarb in many recipes! Whether it is simply stewed and served with cereal for breakfast, in a rhubarb cordial, or in a delicious cake recipe such as this one. In our vegetable garden we have three rhubarb plants and they are always put to good use!


In all of my recipes there are measurements in grams. It is way more accurate. Consequently, you need a kitchen scale to make this recipe. Here’s the link to the scale that I use, but there are cheaper ones as well.


Gluten free flours: Millet flour, tapioca starch, and oat flour are used for the best texture. Quinoa flour can be replaced with gluten free oat flour if you prefer, but I have tried this recipe with both and it is equally as good.

Sugar: In my opinion any dish with rhubarb needs that sweetness added and the combination of white and brown sugar is perfect.

Eggs: Three large eggs help to bind the gluten free flours used. I have not tried this recipe with flax eggs.

Rhubarb :You will need about 4 large rhubarb stalks, thinly sliced

Strawberries: Sliced strawberries combine so well with the rhubarb.

Cinnamon:just a touch of cinnamon on the topping adds to the flavour

Whole Oats:the crunchiness of the baked oats with butter and sugar are so tasty and add that extra crispiness.
