Preparation
Preheat oven to 350°. Mix sugar, coffee granules and cinnamon. In a large bowl, beat butter and sugar until crumbly, about 2 minutes. Beat in egg and vanilla. In another bowl, whisk together flour, baking powder, baking soda and salt; add to butter mixture alternately with yogurt, beating just until blended. (Batter will be thick.)
Spread half of the batter evenly into a 8-in. square baking pan coated with cooking spray; sprinkle with half of the coffee mixture. Top with remaining batter; sprinkle with remaining coffee mixture. Cut through batter with a knife to swirl. Sprinkle with nuts.
Bake until a toothpick inserted in center comes out clean, 25-30 minutes. Cool 5 minutes before serving.
