In a large bowl, sift and mix flour, baking soda and baking powder
Mix well till everything is combined well. Keep it aside.
In another bowl, add oil, granulated sugar, yogurt and vanilla extract and mix everything well.
Add the wet ingredients to the dry ingredients
Mix using a whisk or electric hand mixer till you everything is mixed well and you get a very thick, tough mix.
Add water, in small increments while mixing in between, till you get a very smooth batter.
Break up 25 Oreos in small chunks and add into the batter
Carefully fold and mix the Oreos till equally distributer in the batter.
Take three 7 inch cake pans and line them with parchment paper. Grease with butter on the bottom and sides of the cake pans.
Carefully pour the batter into each pan and fill it up to halfway up the pan
Pre-heat the oven to 350 F and bake for 30 to 40 minutes or till a skewer/toothpick inserted in the center of the cake comes out clean.
Once baked, remove the cake from the pan. Run a knife along the walls of the pans to release the cake from the walls of the cake pan. Let the cakes cool down on a wire rack
Once cooled, use a knife or a Wilton Cake Leveler* to cut off the top dome part of each cake to get a flat even surface.
