In mixer beat butter until smooth.
Add sugar and mix until fluffy, about 3 minutes.
Add eggs one at a time and incorporate completely
Mix in vanilla.
On Low add flour with baking powder in three additions alternating with the milk (beginning and ending with flour)
Do not overbeat, just mix in each addition until well blended.
Bake at 325 degrees until cake is fully cooked and the toothpick comes out clean.
Separate the batter into three bowls the total batter is 8 cups. Each bowl will have 2 2/3 cup batter, tint one orange, one yellow, and the other white, (yes they have white coloring it's one of my favorites, it makes it bright white) I use Americolor Colorings. The yellow is egg yellow.
These cakes were baked in 7-inch pans that was sprayed with a baking spray.
My cakes baked for 55 minutes.
Cool cakes completely.
I baked my cakes the day ahead and wrapped them in plastic wrap and placed them in the refrigerator overnight for them to firm up and be easier to stack when icing them.
