Preheat oven to 350 degrees. Spray three six-inch cake pans with non stick spray and line the bottoms with parchment paper rounds. Set aside.
Add the butter and sugar to a large bowl and cream together with an electric mixer.
Then add in the egg white and vanilla and mix until smooth, about 1 minute.
Next add in the honey and buttermilk and combine.
In a separate bowl whisk together the cake flour, cinnamon, baking powder, baking soda and salt.
Add the dry ingredients to the wet ingredients and mix until the batter is smooth.
Evenly divide the batter between the prepared cake pans. Bake the cakes for 29-34 minutes or until a toothpick comes out clean from the centers with a few moist crumbs.
Let the cakes cool in their pans for 10 minutes, then transfer them to a cooling rack to finish cooling.
