Here’s what you’ll do for the melty masterpiece of your choice:
1. Let ice cream stand at room temperature until slightly softened, about 5 minutes. Scoop into a large bowl; break into pieces using a wooden spoon or rubber spatula.
2. Add stir-ins, and gently fold until evenly incorporated.
3. Spoon ice cream into a 9- x 5-inch loaf pan; cover with plastic wrap, pressing directly onto surface of ice cream. Freeze until firm.
