Recipes for homemade Irish cream are available at AllRecipes.com, on Taste of Home magazine's website, TasteofHome.com. The Irish cream produced from the AllRecipes.com instructions keeps for two months if refrigerated.
To make homemade Irish cream, gather 1 cup of heavy cream, 1 can of sweetened condensed milk, 1 2/3 cups of Irish whiskey and 1 teaspoon instant coffee granules. To prepare the recipe, combine all ingredients in a blender and blend on high for 20 to 30 seconds. Store in a tightly sealed container in the refrigerator, and shake well before serving.
Taste of Home's Irish cream recipe substitutes chocolate syrup, milk, sugar, and vanilla and almond extracts for whiskey, resulting in a non-alcoholic version of the coffee additive.
