Preheat your oven to 350 degrees and spray your bundt pan with non-stick baking spray.
Using your stand mixer fitted with the flat beater attachment, beat together the yogurt, sugar, eggs, lemon zest, and vanilla. Once combined, pour in the olive oil and beat again on low speed.
In a separate large sized mixing bowl, combine the flours, baking powder, and salt. Keeping the mixer on low speed, slowly pour the dry ingredients into the wet and beat on low until fully incorporated.
Pour the cake batter into the prepared bundt pan and bake for 60 minutes, or until a tester comes out clean. Let the cake cool for a good 20-30 minutes before inverting and removing from the bundt pan. Serve, slice and enjoy!
