1-First step: Gather and chill everything. Set out your ice cubes, cold heavy cream, fresh lemon juice, and sweetened condensed milk. The colder the ingredients are, the fluffier the whipped layer will be. If you are making this for guests, chill your glasses too for an extra frosty finish.

2-Second step: Whip the creamy layer. In a medium bowl, add the 1/4 cup cold heavy cream and 1/4 cup sweetened condensed milk. Use a hand mixer or a whisk to whip until the mixture looks thick and fluffy. You want it airy, but still spoonable. This usually takes about 1 to 2 minutes with a mixer, and a little longer by hand.

3-Third step: Add the lemon juice. Slowly pour in the 1/4 cup freshly squeezed lemon juice from 2 medium lemons. Stir gently so the mixture stays light and creamy. The acid from the lemons helps balance the sweetness and gives the drink that classic whipped lemonade flavor people love.

4-Fourth step: Build the drink. Fill each glass with 1 1/2 cups ice cubes. Then pour the whipped lemon mixture over the top. If you want a more layered look, pour it slowly so the cream floats a little on top of the ice. This is what gives the drink its fun, cloud-like look.

5-Fifth step: Add the final touches. Top with whipped cream if you want a fuller dessert style drink. Add a lemon slice for garnish if you like a pretty, café-style finish. Serve right away while it is cold and frothy.
