Instructions
Cake/Sponge
-
In an electric stand mixer or hand mixer, cream butter and cream cheese together.

Add brown sugar and white sugar and beat until fluffy on a medium speed.
-
On a lower speed, mix in 1 egg at a time. Mix thoroughly in between eggs.
-
Add vanilla and mix well.
-
In a large bowl sift together the gluten-free Cup4Cup flour, baking soda, cornstarch, and salt. Set aside.
-
In a small bowl, mix together the milk and vinegar and set aside for 5 minutes.

Cinnamon Ribbon Layer
-
Mix together the cinnamon and sugar.
