This is a fantastic no-churn ice cream with deep chocolate and Baileys flavors that don't overpower each other. It's eggless and no ice cream machine is needed.
Beat 2 cups cold heavy cream until thick but not completely firm. Use an electric mixer or stand mixer with the whisk attachment.
Sift ½ cup unsweetened cocoa powder into 1 can sweetened condensed milk. Stir to mix.
Add ¼ cup Baileys liquor and ½ teaspoon vanilla extract and mix until thoroughly combined.
Add the whipped cream in two parts into the chocolate mixture and fold it in with a spatula or whisk. Integrate thoroughly. Use a spatula to scrape the bottom of the mixing bowl and make sure no white streaks remain.
Pour into a large metal pan without a removable bottom (8-inch round or square pan or 2 medium loaf pans).
Freeze for 4-6 hours or until completely firm.
Scoop it into bowls and serve it plain with your favorite toppings.
Cover tightly with plastic wrap for longer storage, or use a freezer-safe container to avoid freezer burn.
Notes
Sweetened condensed milk: depending on the country, you might find sweetened and unsweetened (known in many places as evaporated milk). Make sure it has sugar.Unsweetened cocoa powder: in my experience, the dark ones are the best (this does not apply to the super dark used for making homemade Oreo cookies known as dark or black cocoa powder).
