Ingredients and Substitutions

  1. 1 cup hot milk
  2. 3 eggs
  3. 4 tablespoons butter
  4. 2 cups demerara sugar (use half if making fillings separately)
  5. 1 cup cocoa powder
  6. 2 cups oat flour
  7. 1 teaspoon baking soda


  • For demerara sugar: Brown sugar can be a suitable replacement.

  • For cocoa powder: Experiment with any cocoa powder ranging from 32% to 50%.


Mixing the Dough:

Begin by combining hot milk, eggs, butter, demerara sugar, cocoa powder, oat flour, and baking soda in a mixer. Ensure a thorough mix before adding the baking soda. Beat for about 15 seconds until the consistency is smooth.

Baking the Cake:

Transfer the mixed dough into a greased round mold with a hole in the center. Bake in a preheated oven at 180 degrees for approximately 40 minutes, or until a toothpick comes out clean.

Creating the Filling:

  1. Prepare fake condensed milk using the provided recipe.
  2. In a pan, mix the fake condensed milk, light milk cream, and cocoa powder.
  3. Heat the mixture until it boils, then simmer for 5 minutes. Allow it to cool before filling the cake.

Assembling the Cake Layers:

  1. Cut the baked cake into layers.
  2. Wet each layer with a syrup made from 500ml of water and 100ml of condensed milk.

Building the Cake:

  1. Layer the cake, adding the filling between each layer.
  2. Drizzle the syrup over the assembled cake.

Slicing and Serving:

Render 24 slices of cake, perfect for a lunchbox of 220ml.


If you’re making separate fillings, use only half a cup of demerara sugar.

Top 4 Mistakes and How to Avoid Them

1. Rushed Mixing:

Avoid a hurried mix. Take time to ensure all ingredients are well incorporated, especially when adding the baking soda.

2. Incorrect Syrup Application:

Ensure the syrup is mixed well before drizzling. Inconsistent syrup distribution can lead to uneven moistening of the cake layers.

3. Overlooking Filling Cooling Time:

Allow the filling to cool adequately before applying it to the cake. Rushing this step might compromise the cake’s structure.

4. Neglecting Half-Sugar Option:

When making fillings separately, remember to use only half a cup of demerara sugar to maintain the perfect balance of sweetness.


1. Can I use regular flour instead of oat flour?

Yes, you can substitute oat flour with whole wheat flour for a slightly different texture.

2. Is there a specific brand of cocoa powder recommended?

Feel free to experiment with any cocoa powder, ranging from 32% to 50%, based on your preference.

3. Can I freeze the cake slices?

Absolutely! Ensure proper packaging, and the cake slices can be frozen for up to three months.

4. Can I replace demerara sugar with artificial sweeteners?

While it may alter the taste, you can experiment with small quantities of artificial sweeteners as a substitute.

5. How long does the ganache take to set?

Allow the ganache to set for at least 1-2 hours before slicing the cake for the best results.
