Prep a Bundt pan by spraying the inside of the pan with a baking spray containing flour (you can find this spray in the baking aisle at your grocery store). This step is so important if you want your cake to slide out of the pan. Set aside.
In a large mixing bowl sift together the flour, sugar, cocoa, baking soda, baking powder and salt.
In a separate bowl, whisk together the yogurt, milk, eggs, vanilla, coffee and vegetable oil.
Add the yogurt mixture to the dry ingredients, then use an electric mixer on medium speed to mix for about 2 minutes.
Pour the cake batter into the prepped Bundt pan. Gently tap the pan on the countertop to remove air bubbles.
Bake for 50-60 minutes, or until a toothpick inserted in the centre of the cake comes out clean.
When done, let the cake cool in the pan on a wire rack for about 15 - 20 minutes before removing the cake.
