In a large bowl, pour in the heavy whipping cream.
Mix with an electric mixer until fluffy.
Add condensed milk and with a spatula, combine very well folding into whipping cream. Stir in one direction.
Transfer half the mixture into a plastic container with a lid. (Pour in only half of it.) Then add Oreos or your favorite toppings. Mix. Add more according to your liking.
Pour in the remaining half of the mixture into another container and repeat the same process.
