1 cup plain yogurt
1 cup minus 2 tablespoons finely ground maple sugar*, divided
2 eggs
1/3 cup vegetable oil
2 cups minus 2 tablespoons flour
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
a good pinch salt
one large apple of a variety that holds its shape when cooked (I used Golden Delicious)
1. Preheat the oven to 180° C (360° F) and line a 25-cm (10-inch) cake pan with parchment paper.
2. Set aside 1 rounded tablespoon of the maple sugar for topping.
3. In a medium mixing bowl, whisk together the yogurt, the remaining maple sugar, eggs, and oil. In another mixing bowl, combine the flour, baking powder, baking soda, and salt. Peel the apple, then core, quarter, and slice it thinly. Add the flour mixture to the yogurt mixture and whisk it in quickly, until just combined. Don't worry about lumps and do not overmix.
4. Pour the batter into the prepared pan, arrange the apple slices on top, starting from the outside, and sprinkle with the reserved maple sugar.
5. Put into the oven to bake for 40 minutes, until the top is golden and a cake tester inserted in the center comes out clean. If you feel the apple slices might be browning too quickly, cover with a piece of parchment paper.
6. Let cool on a rack and serve, warm or at room temperature.
* If maple sugar is unavailable, substitute 3/4 cup maple syrup and use just 3/4 cup yogurt to make up for the extra moisture.
Easy as cake! I used syrup with the lesser amount of yogurt as noted. And I only had 9" cake pans, so used my 10" cast iron skillet. It all comes together really quickly and is so tasty and moist.
