Beat eggs with sugar until fluffy. Add lemon zest, oil, and yogurt and mix until combined. Stir together flours with baking powder and salt, then add to wet ingredients with mixer on low just until incorporated. Add thyme and pint nuts, mixing on low to combine.
Pour into an oiled 8″ round cake pan and bake at 350 degrees until a toothpick comes out clean, about 30-40 minutes. Let cool on a wire rack for 20 minutes, then remove to a cake plate. Dust with powdered sugar before serving if desired.
