  3. In the bowl of an electric mixer beat together butter and sugar until smooth and fluffy, add eggs one at a time and beat well until light and fluffy, add vanilla. Set aside.

This cake really works well in a removal bottom brownie pan. This will allow the sticky cake to be removed easily and cut into squares. You can find one here. (this link goes to Amazon where I am an affiliate partner)

You can use frozen berries for this recipe just be sure you don’t over mix the batter or your cake will turn blue!
