Upside-Down Rhubarb Cake

Ingredients (one 20–22 cm cake, serves 8)

For the cake:

  • 200 g rhubarb, chopped

  • ½ cup coconut flour

  • 1 tsp baking soda

  • ½ tsp baking powder

  • Pinch of salt

  • 1 tsp vanilla extract

  • 1 tsp apple cider vinegar or lemon juice

  • ½ cup unsweetened plant milk

  • ⅓ cup coconut yogurt (or applesauce)

  • 2 tbsp pumpkin purée or almond butter

  • 2 tbsp erythritol or coconut sugar (adjust to taste)

For the beet-berry glaze:

  • 1 small cooked beetroot

  • ½ cup frozen or fresh berries (blueberries or raspberries)

  • 3 tbsp coconut yogurt

  • 1–2 tbsp erythritol or another sweetener

  • 1 tsp lemon juice (optional, for tang)

For decoration:

  • Walnut halves

  • 1 tbsp coconut yogurt (center topping)


Directions

  1. Preheat the oven to 180°C (355°F). Grease a 20–22 cm round baking dish or line with parchment.

  2. In a bowl, mix dry ingredients: coconut flour, baking soda, baking powder, salt, and protein powder if using.

  3. In a second bowl, whisk together plant milk, yogurt, pumpkin purée, sweetener, vanilla, and vinegar.

  4. Combine the wet and dry mixtures. Stir in the chopped rhubarb. The batter will be thick — that’s normal with coconut flour.

  5. Spread the batter evenly into the prepared pan. Bake for 30–35 minutes or until a toothpick inserted into the center comes out clean. Let cool fully before glazing.

  6. Make the glaze: Blend beetroot, berries, yogurt, sweetener, and lemon juice until smooth and pourable.

  7. Decorate the cake: Pour the glaze over the cooled cake, letting it spread naturally. Arrange walnut halves in a ring and place a spoonful of coconut yogurt in the center.
