How to Make Easy GF Vegan Rhubarb Cake [Sugar-Free]

This easy gluten-free vegan rhubarb cake has only 11 ingredients (not counting sweetener and salt) and doesn’t require advanced baking skills. The dairy free filling is creamy and moist, perfectly combining the sweetness of the batter and sourness of rhubarb.

As soon as the rhubarb season began, I started thinking about rhubarb cake recipe. However, only at the end of the season did I manage to whip up my first ever vegan rhubarb cake.

It makes me so happy that even my husband, who’s not a big fan of rhubarb, approved the taste and texture. Furthermore, when I asked my 8-year-old to describe it, he couldn’t say other than it was so good 🙂

The Ingredients

I started with soaking organic walnuts for the crust. Soaking makes the nuts more digestible and enhances mineral absorption by reducing the amount of phytates. Because I used soaked walnuts, I also added a bit of tahini to get the oily consistency. Other option would be to dehydrate the walnuts and process them until the oils start to separate.

Next, I decided to use oat bran instead of rolled oats to keep the glycemic load of my rhubarb cake really low. However, feel free to add rolled oats if it’s no concern to you (see more under tips).

Now, let’s move on to ground chia seeds, the true wonder in gluten-free and grain-free baking. It’s the substance that glues everything together or makes your mixtures thicker, similarly to psyllium. In fact, it works as a binder in the crust and as thickener in the filling.

I don’t even know how I came to the idea to combine chickpeas and coconut milk to achieve this divine custard-cream-like outcome. However, it’s just perfect! By the way, don’t be intimidated by the overly sweet taste of the filling as baking and the sourness of rhubarb will smooth it out. I’m sure some people would add even more sweetener though 🙂

When it comes to sweeteners I went for erythritol, as I’m willing to live Candida free. However, many people tolerate other sweeteners and can therefore use something else (see more under tips).

  4. While the crust is baking, process all filling ingredients (except rhubarb) in a blender or use immersion blender. Finally, mix in chopped rhubarb.

Tips on my easy vegan rhubarb cake:

  • Instead of walnuts you could use any other preferred nuts – almonds, cashews, hazelnuts, pecans, macadamia nuts.
  • Tahini can be substituted with any other nut or seed butter – almond butter, cashew butter, sunflower seed butter, hazelnut butter.
  • You could use rolled oats instead of oat bran, but add 2 tablespoons instead of 3.
  • Feel free to use any additive-free plant milk in the crust – almond milk, soy milk, rice milk, cashew milk, hemp milk etc.
  • If you’re not struggling with Candida overgrowth, feel free to substitute erythritol with any other preferred sweetener – coconut sugar, coconut nectar, agave syrup, maple syrup.
  • Instead of mixing chopped rhubarb right into the filling, you might also add layers of rhubarb and the filling by turns leaving rhubarb on top. Feel free to sprinkle some extra cinnamon on rhubarb pieces.
  • You can make this rhubarb cake even more blood sugar and gut friendly by sprouting the chickpeas before cooking them. Chickpeas will take about 24 hours to have 1-2mm sprouts.
  • Finally, if rhubarb season is over, use any sour berries such as redcurrant, blackcurrant, bilberries, sour cherries, sea buckthorn or even strawberries and sour apples.
