How to make light, fluffy vanilla cakes?
Every time I try to make a vanilla cake it comes out incredibly dense and heavy. Here’s the recipe I used:
3 2/3 cups (433g) cake flour
• 1 tsp salt
• 2 tsp baking powder
• ¾ tsp baking soda
• 1 ½ cups butter, room temperature
• 2 cups sugar
• 3 eggs + 2 egg whites, room temperature
• 1 tbsp vanilla extract
• 1 ½ cups buttermilk, room temperature
I whipped the egg whites to stiff peaks separately and folded them in last because I read that as a tip online, and I whipped the butter longer. I also increased the baking powder (?) (I think, this cake was a while ago) and weighed the cake flour. I cannot seem to get a light, fluffy cake no matter what I do. It was extremely dense, honestly it might have been denser than my chocolate cake. Any ideas? The recipe was from Sally’s baking addiction.
