So excited to share this vegan recipe for my German Rhubarb Cake with you guys today! A healthy gluten-free and vegan spin on traditional German cake recipe! Rhubarb season is finally in full swing here in Canada and I cannot wait to make all my favorite rhubarb recipes.
This easy rhubarb cake is the kind of cake that takes minutes to make and that is perfect for breakfast or a sweet afternoon treat. It is made with a mix of oat flour and ground almonds, making it super moist AND gluten-free. I love the texture, it’s so so wholesome with wonderful juicy tart bursts in the middle, thanks to the chopped rhubarb.
Baking gluten-free cakes with oat flour:
I love baking with oat flour as it behaves so much like wheat flour. It lends soft and fluffy texture to cakes and quick bread and comes with a mild flavor, slightly nutty. Especially delicious when paired with tangy rhubarb.
The absence of gluten definitely makes a difference in a cake so this cake is not super light and airy in texture. It is more similar to cakes baked with spelt or whole wheat flour than to refined wheat flour.
You can make oat flour from whole rolled oats at home. You just need a good blender, coffee or spice grinder or food processor.
If you’re not extremely sensitive to gluten, any oat flour will do for this recipe. If you have celiac disease it’s important to look for gluten-free certification—you’ll see it displayed prominently on the package.
What can I use instead of oat flour?
You could make this recipe for vegan rhubarb cake with whole wheat flour or spelt flour if you don’t mind gluten and don’t feel like grinding oats. Wheat flour of course works as well. The baking time might be shorter so check after 35 minutes.
Tips for making this recipe for rhubarb cake:
- To make oat flour, simply process oats in the blender until you obtain a fine powder.
- Xanthan gum is an optional addition, but it will help your cake hold together a little better and not crumble
- This version baked in a 20-cm springform pan will stay quite juicy and moist for days.
- Instead of coconut sugar, you can use brown sugar or date sugar to keep it refined sugar-free.
- For a lighter texture, use whole wheat flour instead of oat flour.
