I based my cake recipe on my classic, super simple, very easy to make one-bowl "plain" cake.
1 cup flour
1/2 cup sugar
1 t baking powder
1/6 cup oil (I use soy)
1/2 cup water
1 t vanilla
mix dry ingredients
add oil and water
pour in pan
bake medium heat, every oven is different, until pops up when center of cake is gently pressed
If it seems done on top and loose inside, then lower the heat a bit.
You can ice, sugar or serve plain.
*Bli neder, I'll blog about the challah baking later.
