Preheat oven to 350°F.
In a bowl, add 1 container of vanilla yogurt, 1 container of vegetable oil, 2 containers of sugar, and the zest of 1 lemon. Whisk to combine.
Add 3 eggs and a splash of vanilla extract, and whisk again to incorporate.
Add 3 containers of all-purpose flour, 1 tsp of baking powder, and ¼ tsp of salt. Mix until just combined.
Grease a 9-inch bundt pan with non-stick spray and pour the batter into the pan, smoothing the top.
Bake for 40 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool in the pan for 10 minutes, then invert onto a wire rack to cool completely.
