Method


Cake

This recipe is best made in two separate batches. Prepare and bake the first two layers using half the ingredients, then repeat with the remaining ingredients for the second two layers.

  1. Preheat and line: Preheat the oven to 180 degrees Celsius. Line two cake tins with parchment paper.
  2. Mix wet ingredients: Combine half the Greek yoghurt, applesauce, date syrup, eggs, and vanilla extract in a large bowl and mix until smooth.
  3. Mix dry ingredients: In a separate bowl, whisk together half the flour and whey protein. If using plain flour, add 1 tsp baking soda and a pinch of salt.
  4. Combine: Gently fold the dry mixture into the wet mixture until just combined. Do not overmix. Fold in sprinkles if using.
  5. Bake: Divide the batter evenly between the two tins. Bake for 18 to 20 minutes, or until a toothpick inserted into the centre comes out clean. Do not overbake; the centre should be just set for the best texture.
  6. Cool: Remove from the oven and allow to cool completely in the tins before handling.
  7. Repeat: Once the first batch has baked and is cooling, repeat steps 1 through 6 with the remaining ingredients to produce your third and fourth layers.


Frosting

  1. Blend: Add cottage cheese to a blender or food processor and blend until completely smooth and creamy.
  2. Mix: Transfer to a bowl and stir in whey protein and vanilla essence until well combined. Taste and add date syrup or monk fruit if extra sweetness is needed.
  3. Assemble: Once all four cake layers are fully cooled, spread frosting between each layer and over the top. Decorate with sprinkles as desired.

Storage: Store assembled cake in an airtight container in the fridge for up to 4 days. Un-iced layers can be wrapped individually and frozen for up to 1 month.


Date Syrup (makes approx. 160 ml)

You will need: 200 g (12 to 16) Medjool dates, pitted; 240 ml boiling water

  1. Soak: Place pitted dates in a bowl and cover with boiling water. Soak for 10 to 15 minutes until softened. If using regular dried dates, increase soaking time to 20 minutes.
  2. Blend: Transfer the dates and soaking water to a blender. Blend until completely smooth. Add extra water, one tablespoon at a time, if the consistency is too thick.
  3. Strain (optional): Pass through a fine mesh sieve for a smoother syrup. For a cake batter, this step is not essential.


Tip: Medjool dates give the richest, most caramel-like result. Any leftover syrup keeps in a sealed jar in the fridge for up to two weeks.
