Equipment Needed
-
Mixing bowls

Whisk & spatula
-
Measuring cups & spoons
-
Cake pans (6-inch or 8-inch)
-
Oven

Cooling rack
Instructions
-
Preheat oven to 170°C / 340°F. Grease and line cake pans.
-
In a large bowl, whisk together all dry ingredients until well combined.
-
In another bowl, mix yogurt, milk, oil, vanilla, and vinegar until smooth.
-
Add wet ingredients to dry ingredients and whisk gently until lump-free.
-
Slowly add hot water, mixing gently. The batter will be thin — this is correct.
-
Pour batter into prepared pans, filling only ⅔ full.
-
Bake for 30–35 minutes, or until a toothpick inserted comes out clean.
-
Cool in pans for 10 minutes, then transfer to a cooling rack and cool completely before frosting or carving.
Tips
-
Thin batter gives a moist crumb — do not add extra flour
-
Chill layers before carving for clean edges
-
Use light sugar syrup if extra moisture is required
-
Ideal for buttercream frosting and fondant covering
-
Mixing note: Unlike vanilla eggless cakes where sugar and yogurt are whipped for extra fluff, here we gently combine wet and dry ingredients. This preserves structure, giving a stable, moist cake that’s perfect for carving and fondant work.
