Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Caramel Cake
Ingredients
Directions
Cream the butter and sugar together.
Add the eggs and sweet milk, mixing well.
Sift together the baking powder and flour, then add to the mixture.
In a separate bowl, combine the chocolate, milk, and sugar, and flavor with vanilla.
Let the chocolate mixture cool, then fold it into the cake batter along with the beaten egg whites.
For the icing, boil the brown sugar, cream, and butter until it forms a soft ball in water.
Spread the icing over the cooled cake.
