1-First Step: Chill your glass and gather the ingredients Put a serving glass in the freezer for a few minutes while you get the ingredients ready. Measure out 1 1/2 cups ice cubes, 1/4 cup cold heavy cream, 1/4 cup freshly squeezed lemon juice from 2 medium lemons, and 1/4 cup sweetened condensed milk. If you want toppings, set out whipped cream and a lemon slice too.

2-Second Step: Add everything to the blender Place the ice cubes, cold heavy cream, lemon juice, and sweetened condensed milk into a high-speed blender. A strong blender works best here because ice can be tough to break down into a smooth slush. If your blender has a tamper, keep it nearby in case the mixture needs help moving.

3-Third Step: Blend until smooth Blend the mixture for about 1 minute, or until the texture looks creamy and even. You want the ice to be fully crushed, with no big chunks left behind. If the mixture seems too thick, stop the blender and let it rest for a few seconds before blending again.

4-Fourth Step: Check the texture Give the whipped lemonade a quick look before pouring. It should be thick, frosty, and smooth, almost like a lemon milkshake or slush. If you prefer a looser drink, you can blend for a few more seconds with a tiny splash of cold water or a little more lemon juice, but add only a small amount at a time.

5-Final Step: Pour and garnish Take the chilled glass out of the freezer and pour in the lemon cream slush. Top with whipped cream if you want an extra creamy finish, then add a lemon slice for garnish. Serve right away while it is icy cold and fresh.
