In a bowl, add milk and vinegar to make buttermilk. Rest for 5 minutes.
Take a separate bowl, add all purpose flour, baking soda, milk powder and sugar. Mix until nicely combined.
Add the milk mixture into the dry ingredients along with oil. Give everything a mix to gain a smooth pancake batter.
On a non-stick pan, add vegetable oil and add about ¼ cup of the batter. Let the pancakes cook slowly. When you see bubbles on top, flip the pancakes carefully.
In a bowl with whipped cream, fold in the chopped Oreos to prepare the filling.
To assemble the sandwich, use the Oreo filling to fill 2 pancakes and then press down the edges to make a sandwich.
Repeat this process with all the pancakes and enjoy!
