Grease and line an 8-inch cake pan with parchment paper.
Step 2: Mix Dry Ingredients
In a bowl, whisk:
Flour
Baking powder
Baking soda
Salt
Set aside.
Step 3: Mix Wet Ingredients
In another bowl:
Beat eggs and sugar until light and pale.
Add oil and mix well.
Add yogurt and vanilla.
Mix until smooth and creamy.
Step 4: Combine (Gentle!)
Add dry ingredients to wet in 2–3 batches.
Fold gently with a spatula.
Do not overmix — stop as soon as smooth.
Lumps are okay. Overmixing kills softness.
Step 5: Bake
Pour batter into pan.
Tap pan gently to remove air bubbles.
Bake 35–40 minutes.
Toothpick should come out clean or with soft crumbs.
Step 6: Cool Properly
Let cake cool 10 minutes in pan.
Remove and cool completely on a rack.
