• Preheat your oven to 150 degrees celsius or 350 F.Prepare a rectangular baking dish by greasing it with vegetable fat and lightly flouring. 
• Pour yogurt into a small mixing bowl and add thebaking soda, stir and set aside for 7 minutes.
• In a large mixing bowl add sugar and oil and beatuntil thoroughly mixed. 
• You will notice some bubbles forming in the yogurtbecause of the leavening action of baking soda.

  Gently pour the yogurt mixtureinto the sugar and egg mixture. 
• In a separate bowl, whisk the flour, baking powder,and salt. In two batches, add the dry ingredients to the wet ingredients and fold gently with a rubber spatula.

  Mix until all ingredients are fullycombined. Be careful not to over-mix. 
• Pour the cake batter into the greased pan. Bake for 30 to 40 minutes until a toothpick comes out clean.

Mixing the three milks 

• While the cake is baking, mix the three milks in a jar and set aside.

  Taste the sweetness of your milk mixture, and adjust the sweetest to your satisfaction, mild sweetness tastes excellent.

  I believe it would taste delicious if you add a dash of cardamom or saffron.
