1. Preheat oven to 350°F. Grease the bottom of an 8-inch round baking pan.* Line bottom with waxed paper; grease pan. In a medium bowl whisk together flours, baking powder, and salt.
2. In a large bowl combine granulated sugar and zest. Using fingers, rub zest into sugar until sugar is moist and aromatic. Add yogurt, eggs, and vanilla; whisk until well blended. Gently whisk in flour mixture. Using a large rubber spatula, fold in oil until combined. Spread batter in prepared pan.
3. Bake 40 to 45 minutes or until top of cake feels springy and a toothpick comes out clean. Cool cake in pan on a wire rack 15 minutes. Use a knife to loosen edges of cake from pan. Remove cake from pan; peel off waxed paper. Cool on wire rack.
4. Dust cake with powdered sugar. Serve with Apricot-Cherry Compote and, if you like, crème fraîche. Makes 8 servings (1 slice cake + about ⅓ cup compote each).
APRICOT-CHERRY COMPOTE In a large saucepan combine ¼ cup each sugar, water, and dry white wine (such as Sauvignon Blanc) or water, and 1 tsp. lemon zest (optional). Cook and stir over medium heat until sugar is dissolved. Stir in 12 oz. (3 to 4) fresh apricots, peaches, or pluots, pitted and sliced, and 8 oz. (1½ cups) fresh sweet cherries, pitted. Bring to boiling; reduce heat. Simmer, uncovered, about 15 minutes or until fruit softens and syrup thickens. Remove from heat; cool slightly. Transfer to a container; cover and chill before serving.
*NOTE You can bake this cake in a 1½- or 2-inch-deep pan. With a 1½-inch-deep pan, it will be more full, and the cake will bake up to the edge of the pan. Bake at least 45 minutes in this pan.
