Method

Preheat the oven to 350°F. Butter a 9x13-inch baking pan. 

Bring 1 1/2 cups water to a boil in a small pot, and then pour over oats in a large, heatproof bowl; set aside.

In a second large bowl, beat 1 1/2 cups of the sugar, 1/2 cup of the yogurt, 4 tablespoons of the butter, vanilla and eggs with a wooden spoon until combined. 

Stir in flour, baking soda, cinnamon, and 3/4 teaspoon of the salt, and then stir in oatmeal mixture until well combined. 

Transfer to the prepared pan, spread out evenly, and bake until golden brown and the cake springs back in the middle when touched, about 35 minutes. Set aside to let cool completely.

Once cake is cool, make the icing. In a small bowl, whisk together remaining 1/2 cup brown sugar, remaining 1/4 cup yogurt, remaining 2 tablespoons butter and 1/4 teaspoon salt until well combined. 

Spread over cake, cut into squares and serve.
