Preheat oven to 350 degrees F.
Prepare a 9-inch springform pan by lightly spraying well with cooking spray or grease and flour the pan. A 9 inch square baking dish would work too, as long as it is at least 3 inches in height. Set aside.
In a large bowl with stand mixer, cream together butter and sugar until light and creamy, about 3 minutes.
Add yogurt, eggs, oil, vanilla and cinnamon, and mix to combine.
Add flour, baking soda, and salt and mix until smooth.
Spread into prepared baking dish. Set aside.
