A simple, tasty cake that takes only minutes to prepare. Make it as written, with candied or crystallized ginger, or substitute oranges or lemons as described in the note below.
Preheat oven to 350° F/180°C. Oil the bottom and sides of the pan, then place a parchment round on the bottom. Set aside.
Whisk together the flours, sugars, ground ginger, baking powder and salt in a medium bowl.
Using a larger bowl, whisk together the yogurt, eggs, vanilla extract, and oils.
Add the dry ingredients to the wet ones, and stir only until the ingredients are combined and no dry ingredients are visible.
Pour the batter into the pan, sprinkle the chopped candied or crystallized ginger, and bake for approximately 25 minutes, until a toothpick or other tester comes out dry, with just a few crumbs adhering to it.
Cool the cake on a wire rack for approximately 15 minutes. While it is still warm, unmold the cake by flipping it onto the wire rack, then inverting it onto a platter so the chopped candied or crystallized ginger is on the top. Once it is cool, you may dust the top with powdered sugar, using a small sieve.
