Notes

The butter and eggs should be room temperature. I try to let them sit out for about 30 minutes before I begin
½ cup of chocolate chips would be a great addition to this cake.
I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
