way to cook:
Blend the eggs, sugar, milk, oil, melted butter, and vanilla until smooth.
Add the flour, baking powder, and salt into the blender and pulse gently until the batter is just combined without over-mixing.
Pour the smooth batter into a greased and lightly floured 8-inch pan.
Bake in a preheated oven at 170°C–175°C until the top is golden and a skewer inserted comes out clean.
Allow to cool before slicing or frosting.
