Preheat the oven to 350 degrees F and spray the inside of a loaf pan with non-stick spray. Set aside.
In a medium mixing bowl (or stand mixer fitted with a paddle attachment), mix the softened 2 cups ice cream and 1 1/2 cups self-rising flour just until combined. Fold in 2 tablespoons rainbow sprinkles with a rubber spatula until evenly mixed in.
Pour the batter into the prepared loaf pan and spread it into an even layer.
Bake for 40 to 45 minutes or until a toothpick comes clean when inserted into the center. Cool completely before topping.
Whisk together 1 cup powdered sugar, 1 tablespoon milk, and 1/2 teaspoon vanilla extract until smooth (adding more sugar or milk as needed to reach your desired consistency). Spread over the top of the loaf and top with more sprinkles. Slice and enjoy!
