Ingredients:
1 stick unsalted butter, at room temo
1 1/2 cups sugar
2 eggs, room temp
1 cup Greek yogurt, at room temp
1 tsp vanilla
1 tsp baking soda
1 tsp baking powder
1/2 tsp salt
1 tsp cinnamon
2 cups fresh plums, diced
1/2 cup chopped pecans
Preheat oven to 350. Ina says to grease a 9" square pan, but this was not big enough. Definitely use a 9 x 11 or even a 9 x 13.
In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and 1 cup of the sugar for 3-5 minutes, until light and fluffy. With the mixer on low, add eggs, one at a time, then the yogurt and vanilla, and mix until smooth. In a separate bowl, sift together flour, baking soda, baking powder and salt. With the mixer on low, slowly add the dry ingredients to the batter and mix just until combined. In a small bowl, combine the remaining sugar with the cinnamon.
Spread half of the batter evenly in the pan. Top with half of the plums, then sprinkle with 2/3 of the sugar mixture. Spread remaining batter on top, arrange the remaining plums on top and sprinkle with remaining sugar and pecans.
Bake for 45-55 minutes, until toothpick inserted into center comes out clean.
No photos of the finished product because, cakewreck! But here are a couple photos of the gorgeous plums I had:
