Chill the all-purpose cream and the condensed milk in the fridge for at least 2 hours

Arrange a layer of graham crackers on your container. The thickness of the slider will depend on the dish you're using.

Open and pour the all-purpose cream into a bowl and whisk to expand (soft or stiff peaks will do).

A hand mixer would be faster but a whisk will do the job.

Add the chilled condensed milk and the vanilla extract to the cream and whisk it to combine.

Pour the mixture into the container, level the top with a spatula or cake scraper then cover the top with another layer of graham crackers.

You may also add another layer of graham crackers in the middle. Just pour half of the cream mixture first then add another layer, pour the rest of the mixture and then top it again with another graham layer.

Place it in the freezer and let it chill for at least 24 hours.

Take it out, divide it and it's done. Keep storing the other sliders in the freezer to keep the consistency.

There are a lot optional ingredients you can add to the cream mixture like cashew nuts, almonds, fruits, caramel, etc.

Also, you may quickly dip the graham crackers in coffee before layering them. This will add another bitter-sweet flavor to the sliders. (Just disolve a teaspoon of instant coffee in some water, put it in a bowl and quickly dip the crackers).
